Car Accident Claim Payouts: How Much Money Will You Get After An Automobile Crash?


If you were involved in an automobile accident in which you sustained injuries as a result of someone else’s negligence, you are entitled to be compensated for your economic and non-economic damages. Whether you suffered minor injuries, such as a slight whiplash or cuts and bruises, or more severe injuries, such as broken limbs, internal bleeding, severe soft tissue sprains or strains, the at-fault driver has a responsibility to make you financially whole and to put you back to where you were before the accident occurred. This is true whether that driver has auto insurance or not. If he does not, you will likely have to sue him for your damages. If he has insurance, you, or your attorney, will be working with a claims adjuster employed by his insurance company, to try to obtain a settlement. This may or may not involve filing a lawsuit and going to court, depending on whether or not you and your attorney see eye to eye with the insurance company on the value of your insurance claim.

Evaluation of your claim
How an adjuster evaluates an injury claim depends on the company’s procedures, but in general, these are the criteria he or she takes into account when determining how much money an injured individual should receive to settle his or her claim:

• Facts of the accident
What happened, at what speed, where, who was involved, were any laws broken, were the police called to the scene, was anyone ticketed, etc., are the basic facts the adjuster will consider.

• Liability

Claims adjusters must evaluate a claim for fault before offering any settlement. If one party is clearly liable and there is no question, it is not a difficult issue. But there are accidents where it is difficult to determine who was responsible, such as those in an uncontrolled intersection, or a left turn made in front of a speeding car entering the intersection. Sometimes reconstruction experts need to be employed to evaluate the accident scene, the damage to the cars, etc. in order to determine what actually happened to figure out who was in the wrong. Sometimes it is determined that both parties were negligent and fault may need to be apportioned.

• Extent of Injuries
The adjuster will request certain information regarding your injuries so he or she is able to determine how injured you really are. They sometimes look at injuries with a rather skeptical eye. Since fraudulent claims are fairly common, don’t take it personally. Just provide what they are asking for. Usually they want a medical report from your physician with a diagnosis and a prognosis for your recovery. They want to know what treatment and/or medication was prescribed and what the status of that treatment is now. Their experience helps them to determine if the treatment was reasonable and necessary for your type of injuries. They may ask if your doctor told you to take time off from work. This way the adjuster gets a complete picture of the difficulties you are having since the accident.

• Expenses

This is fairly simple. How much did you spend on medical bills as a result of the auto accident? How much did you lose in wages? Any other expenses? You will need to provide documentation to support your claim: copies of medical bills and statements, wage stubs, receipts for medicines and other expenses. One difficult item to prove may be how much money you lost if you have your own business and you had to miss work. Sometimes a financial expert is required to help determine the losses. Then there is the damage to your property that needs to be submitted, unless your own insurance pays for it. If the at-fault driver’s insurance will be paying, you will need to provide at least one repair estimate; they will likely want to take a look at the vehicle themselves if where, or to what extent the car is damaged will help determine liability.


• Other Factors

Sometimes there are other factors involved that should be taken into account and you might want to point them out to the adjuster who is evaluating your insurance claim. For example, if you were caring for young children or an elderly relative before the accident and now you cannot, you may need to hire someone to do so. If you were working in a job requiring physical activity that you can no longer do either temporarily or permanently, you’ll want to let them know. If you can no longer do housework and have to hire someone or your spouse has to take time away from work to do that, tell them. All of these factors affect the value of your claim.


Once the adjuster has all of the necessary documentation to evaluate your claim, it is really quite subjective. He or she will come up with a value range based on all the information and make you an offer, likely from somewhere near the bottom of their range. There is no set formula, like 3 times the medical bills, although many use that as a guide. They do not expect you to take their first offer; they expect you to negotiate. If you have an attorney, he or she will do the negotiating for you. If you do not, you are on your own.

Remember that insurance companies are not in the business of spending a lot of money on claimants. They want to protect themselves and their bottom line, and not pay more than they have to or than they believe is a fair amount. But if you negotiate wisely, you can get them to the top of their range and walk away satisfied. If you believe their range is too low, and your attorney agrees, it is time to go to court.

Auto Insurance Deductibles: How Much Should Your Deductible Be?


We would all like to save money when it comes to buying auto insurance, but, as my mother always told me, don’t be penny-wise and pound foolish. If you have never purchased auto insurance before, or even if you have, you should be aware that one of the important decisions you will have to make is at what dollar amount to set your collision and comprehensive deductibles. For these two types of coverage, the deductible amounts will be a determining factor in how much your premium is.

A central rule to remember with auto insurance is: the higher the deductible, the lower the premium--but the more you'll pay out of pocket in case of a claim; the lower the deductible, the higher the premium--but the less you'll fork over if you have an insured claim.

All auto insurance policies that cover collision and/or comprehensive have a deductible. The deductible is the part of your policy that you are responsible for paying. Auto insurance policies don't simply take care of all of your damages or expenses. You are required to pay for some of the damages, but that amount depends on your deductible. Deductibles vary by state, but are most often in amounts of $100, $200, $500 or $1,000. How does it work? If you are in an accident that causes $3000 worth of damage to your car, and your deductible is $500, you are required to pay the $500 and the insurance company will take care of the remaining $2,500. If you carried a $100 deductible, you would pay the first $100, and then your insurance would pony up the remaining $2,400.

How to decide
It’s not always easy to decide how much you are willing to pay now (for your premium) versus later (for your deductible) should you need to make a claim. Some of the factors to take into consideration are your:

• income
• credit
• savings
• comfort level
• age of your car
• driving history
• premiums

Think about your household income, credit available and your personal savings. If you were to experience a car accident today- what amount of money would you feel comfortable paying as your deductible? In other words, what do you have in the bank or available on your credit card, and how much can you get your hands on if you need to that won’t have a huge impact on you or your family? If your current deductible is higher than that amount--make it lower! If you could easily afford to pay more--you might want to increase your deductible in order to lower your premium.

Much of it has to do with risk. Are you willing to take the risk by having a large deductible that you won’t have an accident, or if you do, that you’ll be prepared to cover that amount? Are you comfortable with that, or are you going to fret over it?
So you see that which option you choose (high deductible/lower rates or low deductible/higher rates) will depend on what you can afford, but it also depends on how often you expect to need your insurance. While no one expects to have an accident, you know your driving history; if you tend to have a fender-bender of some sort every few months, you will likely want to pay the minimum amount and let the insurance company take on the majority of costs. For safer drivers who have an excellent driving record, it makes sense to go with the higher deductible and pay lower premiums instead.

Questions to ask yourself
Every so often, make sure to review your auto insurance deductible and consider these two questions:
• Has my household income changed since I set this deductible?
• Does this deductible still reflect the amount of money I would be able to pay in the event of a claim?

Purchasing car insurance doesn’t have to be confusing. Take the time to go over the numbers and figure out what you would be able to afford out of pocket in case of an accident and how much you can afford to pay on a monthly basis. A little research can go a long way. It’s also helpful to speak with the auto insurance agent who can give you a good idea of what the norm would be for your car’s age and your driving experience.

You may remember the battle that raged between pharmaceutical companies who wanted to hold on to their patents and African nations who couldn’t afford the non-generic price tag on the AIDS drugs that would help their dying populations. A similar problem is brewing over green energy technologies: developing countries are demanding that the U.S. waive its patents on clean energy technologies so they can afford to cut their carbon emissions, and the U.S. is saying no way. According to a forthcoming article in The Yale Law Review, the situation benefits no one and is easily remedied.

Wind-Powered Knitting Machine Lets Nature Knit Scarves!

Perusing Designboom this morning we saw this super rad wind-powered knitting machine by Merel Karhof. We had to share this amazing device that beautifully knits tubes using only wind power! The idea initially came to Karhof as she walked by cul de sacs and noticed a consistent breeze flowing outwards. She decided then that she would come up with way to harvest that free energy source and put it to good use. The result – the “Wind Knitting Factory“.

Showcased first at the Hotel RCA exhibition, hosted by royal college of art during Milan Design Week, the Wind Knitting Factory is a 1.2 meter diameter handmade wind mill attached to a loom mechanism. As the wind blows, it spins the loom and knits a scarf tube!

Obviously the stronger the wind is blowing, the faster a scarf can be knit. Each scarf is 2 meters long and is labeled with the day it was made and how long it took to the wind to knit it. Totally powered by free renewable energy without any human power, these amazing little scarves are perfect for wearing on a windy day too!

Vein-Like Piezoelectric Shower Harvests Kinetic Energy to Heat Water

Piezo Shower, I saloni Premio SaloneSatellite, Sebastian Jansson,  Fernanda Piza, Victor Stelmasuk, Natalie Weinmann, piezoelectricity,  energy efficient design, Milan Design Week

This incredible concept for a self-heating piezoelectric shower combines inspiration from the human body’s circulatory system with technological innovations in piezoelectricity. The fluid web of piping heats water by utilizing energy from friction produced by flowing water — it’s therefore able to function completely off the grid. Conceived by Finnish Sebastian Jansson, Mexican Fernanda Piza, Brazilian Victor Stelmasuk and German Natalie Weinmann, the design not only grabs our attention as an exotic art form but also enlightens us with its energy-efficient design.

The Piezo Shower placed second in the ‘I saloni Premio SaloneSatellite’ competition during Milan Design Week. The design was a project of the Master of European Design Programme that took place at ENSCI Les Ateliers Paris and was supervised by Thomas Lommee and Sebastian Müller.

Focusing on new technology allowed the design team to rethink conventional showering systems and create a design that is full of new defining qualities. The design features a network of fibers within its curving and connecting pipes that harvest kinetic energy from friction and generate electricity to heat the water.

The design team explains that the shower is “futuristic yet feasible.” Inspired by the human body’s circulatory system, the designers expanded the area of the piping and added twisting curves that allow for more movement and time for the water to create friction inside the piping.

The shower is controlled through a digital touchscreen that can be integrated into bathroom tiling. The control system also projects waters temperature, pressure and water consumption over-time, providing the necessary details for consumers to adequately monitor their own water waste and energy consumption.

The ‘I saloni Premio SaloneSatellite’ competition was open to contestants that took part in SaloneSatellite 2010 and was reserved for designs that pertained to bathroom and kitchen ambiences.

Bionic Humidifier: A Flower that Helps You Breathe Easier

Gonglue Jiang, bionic humidifier, humidifier, green humidifier,  flower himidifier, bio mimicry, green gadgets

Nature, nurture and design come together in Gonglue Jiang’s Bionic Humidifier — a clever appliance masquerading as a potted plant that also functions as an indoor humidifier. Jiang’s artificial “bloom” wilts and goes limp without continual watering (refilling) and comes in an assortment of colors and shapes — just like the garden variety. “I designed a humidifier simulating a live flower that needs to be ‘nurtured,’” Jiang explains, “which fulfills emotional needs for the users.

The Bionic Humidifier does it all— it moisturizes your apartment, it looks beautiful while it does it, AND it offers the bragging rights that go with keeping something alive! And don’t think this is just decorative folly — this apparatus has been created to live, die and be maintained like a flower, making it more than just another household tool.

No green thumb? No worries — the Bionic Humidifier is much more forgiving than Mother Nature. Once you provide water, your plant will perk back up and resume humidifying. With the looks and mannerisms of a plant, Jiang aims to bring both fresh air and a natural feel into otherwise enclosed spaces, and, unlike typical whirling and fizzing varieties of humidifiers, the Bionic Humidifier provides a “natural breeze effect in home humidifying.

Although not particularly known for its skyscrapers, Latin America will soon have their very own eco tower to add to the growing mix of green skyscrapers all over the world. Torre Reforma, designed by Mexico-based LBR&A Arquitectos, will be Latin America’s tallest building coming in at 244 meters (800 feet), which will put it in somewhere around 180 on the list of the world’s tallest skyscrapers. Even more noteworthy than its height though is that the building is aiming for LEED Platinum certification and will hopefully encourage a wave of green building in Mexico City and the surrounding regions.

Located in downtown Mexico City, Torre Reforma, a 46 story mixed-used development, will sit across the street from Torre Mayor. A historic gothic-style building, which currently exists on the site will be dismantled and rebuilt on the corner of the site and underneath the tower. Inside, the tower will have restaurants, retail, 18 floors of apartments and 26 floors of office space. The tower is currently under construction and is expected to be completed in late 2011.

Halfway up the tower, a two story garden resides in the heart of the building and acts as a vertical park for residents and employees. Floor to ceiling glazing will reveal the park to the exterior and afford views to those inside. On the upper levels, the structural cross bracing membranes, which help stabilize during an earthquake, are visible. The south side of the tower is wedge-shaped and covered in photovoltaic panels to produce power for the building. At night, windows are automatically opened at night to help flush heat from the building. LBR&A Arquitectos has designed the eco tower in hopes of achieving LEED Platinum certification, which will hopefully spur on more green building projects in Latin America.

Ark House

Conceptual architectural design, green building, sustainable  design, sky bridge, Montana home, green design, eco design, sustainable  design, green architecture

Whether for a future flood or a remnant of one from long ago, the Ark House is a provocative residential design that is, ironically, land-locked in the middle of Montana. The design calls for two huge cathedral roofs- one protecting a substantial deck that leads to the next roof over the main house. In addition to making a bold statement, the home boasts some eco-conscious and energy-saving features that Noah himself would likely be impressed with.

Architectural firm Axis Mundi was asked to design a home for a 100 acre site in Madison Valley, Montana that has a contemporary feel but still relates to the ancient landscape. As you enter, you are introduced to a vast covered space not unlike an open barn that leads to a staircase and then a bridge suspended over a pond, after which, the living space finally comes to view. The architect claims a near zero energy profile with a high performance envelope, a ground source heat pump and solar electric panels, presumably built into the roof system. If it ever sets sail there will be plenty of room for all with a 4,800 sq ft deck and 5400 sq ft three story interior.

Storage for your hacking needs

Sometimes your project needs a lot of non-volatile ROM, right on cue [Matthew] let us know how to not only connect, interface, read, and write to SD cards with a PIC over serial, but also how to do the above mentioned with an old PATA HDD. For those without a PIC/serial connection don’t fret, [nada] let us know about his Bus Pirate SD card hack, of which our personal favorite part is the creative use of an old 5.25″ floppy connector as the SD card socket.

Beach stereo

[Adam] wanted a stereo that could stand up to rain and keep sand out. He ended up building this beach stereo out of a cooler. The cooler’s already made to be water tight. He cut holes in the front and back for marine speakers and added a water-tight bezel and cover for the controls on the deck. Inside you’ll find a marine battery to power the unit. Now he and his friends can rock-out even in poor weather thanks to this portable and rugged unit.

Steam powered tank

This steam-powered tank is really something of a steam-electric hybrid. Steam provides the locomotion, but an electrical system provides the remote control and steering. A full boiler will provide 10-15 minutes of operation which you can see in the video after the break. Before you leave a nasty comment: Yes, we realize this project is from several years ago. It’s new to us and the completion date doesn’t diminish the novelty of this well-executed build. This is the quality and uniqueness we’re used to seeing from [Crabfu].

Low Cost Killer Robot

One of our most prolific commenters, [mrgoogfan], shared with us his working BattleBots style robot. Built for under $500, it is capable of zipping around at 25 miles an hour under load. Chances are, this robot would be just as much fun as a Bar Stool Racer as it is with all the weapons attached. The bill of materials also includes a good number of links as well as prices to get the blossoming roboteers in the audience started. We cant wait for the microcontroller automated version, because the idea of a big angry killer Roomba is just the kind of thing that makes us happy. Oh, and we might have a couple suggestions for weapon packages

Check out the video after the break to see [mrgoogfan] zipping around on the top of his robot and showing off the weapons systems.

Have any of you built your own BattleBot or similar platform? We would love to hear from anyone willing to show off a cheaper, faster, smarter, or stronger build, or any tips for people looking to get started in building their own.

Update: Nintendo DS camera control

All of the juicy details needed to control a camera from your Nintendo DS are now available at the Open Camera Control project. This is the descendant of [Steve Chapman's] setup from a few years ago. The system has been polished up and has seen many feature additions. It’s been used in movie production and works with a wide range of cameras.

Start by building your own interface cable using an AVR microcontroller running the Arduino bootloader. Finish up by loading some open source software onto the DS to add a cornucopia of shot options.

Hardware jailbreak eases reboot pains

This device can jailbreak an iPhone. It doesn’t require a computer and it can either reboot a phone that was one-time-boot jailbroken using the blackra1n exploit, or jailbreak a factory fresh unit. We wouldn’t say this solves the tethering problem caused by blackra1n (needing to return to a computer to reboot the phone), but it certainly does ease the pain. We saw some info about the board layout but no parts list or firmware. See the demo after the break and leave a comment if you have more information on the parts or code.

Coffee powered Car-puccino

We can only imagine how amazing this coffee burning car smells at it speeds down the highway at a maximum of 60mph. Don’t jump out of your seat so quick to get your own, while the idea sounds fantastic, the mileage will bring you back to earth rather quick. At 3 miles per kilo of coffee, it can turn that £36 210 mile trip into one between £910 and £1,820 with a stop to re-bean-fill every half hour!

Still, the Car-puccino is an amazing conversion, and we’re getting closer and closer to Back to the Future’s Mr. Fusion

A Zero-Energy Recyclable Espresso Maker

Thursday, April 1, 2010

eco espresso maker, green appliances, green coffee maker,  recyclable espresso maker, green espresso maker, aluminum coffee maker,  aluminum espresso maker, green gadgets

Despite all the reasons why we should cut down on caffeine, it’s hard to say no to that daily little cup of java goodness. So rather than flipping on the switch to your energy hungry espresso maker – or even worse, stuffing your machine with those wasteful single serving plastic containers – we suggest you try the Presso Espresso, an eco-friendly and recyclable espresso maker from designer Patrick Hunt.

Through a controlled blend of pressure and temperature, Presso offers a simple and eco-friendly way to get your daily fix (or fixes!). All you need to do is fill the tamp handle with your choice ground, pack it in, add hot water, raise the handles of the machine to let the water infuse the grinds, and then press the handles downwards to release your piping hot beverage below. Made from polished aluminum, the Presso can also be recycled at the end of its life.

We admit the basic principles behind the Presso Espresso aren’t that different from a traditional moka, or even a French press, but the design is pretty sweet!

Vacuum tube tesla coil

Monday, March 1, 2010

[xellers] may have been in 8th grade when he built this vacuum tube tesla coil, but he did a fantastic job. Unlike most of the tesla coils we have shown, this one doesn’t use a high current transformer from a neon sign. Instead, he’s gone the direction of vacuum tubes. He spent a total of about $125 which isn’t too bad. Most of us could reduce that cost by scrounging from our parts bin.

LEGO router case bests factory finish

Stare at [Luke's] LEGO router case; STARE AT IT! The router is nothing special, a WRT54GL that is fun to hack. We’ve seen it used as a robot, turned into a war driving box, and obviously this is where dd-wrt custom firmware started.

[Luke] designed the case in MLCAD and found a seller for the parts which came in just over $50. We think it’s much better looking than the stock case an if you used that for a different project, this is a way to replace it. We’ve embedded [Luke's] assembly video after the break. If you like this case, take a look at his LEGO PC case as well.

Bike trainer computer: Speed, Cadence, Heartrate, Trainer temp

[Kurt] was using a bike trainer to get in shape for warmer and dryer biking months. Unfortunately it’s pretty hard to train if you don’t have reliable data concerning how hard you’re working. There’s commercial solutions for trainer computers but he’d read some rough reviews about them and decided to build his own trainer computer. He’s done a great job of integrating a lot of different data collection sources. He picked up two replacement bike computer sensors to use on the back wheel for speed (the front wheel is stationary with this type of trainer) and on the crank for cadence. He also wears a heart rate monitor and sourced a SparkFun heart rate module to gather that data. Finally, an LM235 analog temperature sensor was combined with a spring clamp to detect the temperature of the trainer’s resistance module.

Data from the sensors is collected with a PIC16F73 microprocessor and fed to a computer over a serial connection. He’s got a screenshot of the realtime graphs that he’s using for feedback while on the bike. This is a useful and practical setup but when he get’s tired of exercising he’s just a few lines of code from converting this into a gaming controller.

Stroke to unlock

If you’re into embedded clothing this stroke sensor is for you. As demonstrated in the video after the break, stroking the threads in a particular direction will create a circuit that senses and, in this case, turns on an LED. The concept uses two conductive buses on the back of a piece of neoprene. Conductive and non-conductive threads are then added for a furry or bristly finish. When stroked perpendicular to the power buses the conductive threads come together and form a circuit.

For some reason this just seems a bit creepy to us but perhaps that’s only because we haven’t come up with the right application for the technology. We’re pretty sure that a sweatshirt with an LED marquee and a “hairy” back that you stroke to illuminate is the wrong application.

Don’t put that EPROM in your mouth!

[Jeremy] had some chips on hand that included EPROM. We’re not talking about EEPROM, we mean EPROM that need a UV light source to erase. Most people don’t want to drop a few hundred dollars on a dedicated EPROM eraser, there must be another way.

Boy, EPROM really suck. But so do pacifiers and he already had a solution for exposing those to UV. He pulled out his $30 UV pacifier cleaner and tossed the chip inside. Two times through the cleaning cycle and the data was gone. We’ve looked into using UV LEDs to do the job but some experimentation shows that it doesn’t work. These pacifier cleaners are cheap and easy to get a hold of. The real question is are you still using chips that require UV for erasing?

Arduinome with many pots

[Aggaz] added 16 potentiometers to his Arduinome.The Arduinome is a monome clone based around the Arduino as a microprocessor. We seen some Arduinome builds in the past but [Aggaz's] work augments the physical interface.

Potentiometers used in circuit bending allow for manipulation of the sounds coming out of the circuits. In this case the pots are connected to the microcontroller instead of the sound generation circuitry which means you can do whatever you want with them depending on how creative you are with the code. So far he’s just starting to get the new set of interfaces to play nicely over the serial connection. This could end up being quite popular as it only requires the addition of a multiplexer IC, the potentiometers, and the knobs.

Weather clock

[Sean_Carney] build this clock that tells the weather instead of the time. The two hands display the current conditions and the temperature. Forty below zero seems amazingly cold if you’re on the Fahrenheit scale but [Sean's] from Winnipeg so he’s operating on the Celsius side of things.

Two servos move the hands to match the data scraped off of the Internet. An Arduino does the scraping with the help of an Ethernet shield. This reminds us of the Harry Potter clock that tells a persons location.

Amazing chassis hacks

[Crabfu] pulled off some great chassis work on top of a remote control drivetrain. His most recent build turns the tiny traveler into a lunar rover complete with passenger and a communications array. For this he’s sourced the parts from a toy but boosted the realism with hand-painted details that leave us in awe. His previous project sourced the body from a model truck kit. Once again, it’s the paint work that makes us envious of his skills.

Both projects conceal a Losi 1/24 scale micro rock crawler that provides for some incredible locomotion. See video of both builds after the break.

Steampunk Nixie clock

This single-digit Nixie clock is a thing of beauty. You might hate Steampunk or you might love it, but you have to respect projects where the design gets equal (or more) consideration compared to the function. The electronics used in the project build upon an existing single Nixie design. Instead of hiding the guts inside the clock the PCB has been laid out to augment the design. We think [Blue Metal] hit it out of the park with this one!

Kodak digital frame vulnerability

Kodak managed to release a product with a big fat security vulnerability. [Casey] figured out that the Kodak W820 WiFi capable digital frame can be hijacked for dubious purposes. The frame can add Internet content as widgets; things like Facebook status, tweets, and pictures. The problem is that the widgets are based on a feed from a website that was publicly accessible. The only difference in the different feed addresses is the last two characters of the frame’s MAC address. Feeds that are already setup can be viewed, but by brute-forcing the RSS link an attacker can take control of the feeds that haven’t been set up yet and preload them with photos you might not want to see when you boot up your factory-fresh frame.

It seems the hole has been closed now, but that doesn’t diminish the delight we get from reading about this foible. There’s a pretty interesting discussion going on in the thread running at Slashdot.

LEGO robot lays dominoes not eggs

[Mattias] brings the awesome once more with his LEGO robot that sets up dominoes. You’ll remember his work from the wooden keyboard case and the mechanical binary adder. This time around he’s still exercising those woodworking skills by making his own domino tiles, but it’s the robot that makes this interesting. In the must-see video after the break the device lays perfectly straight, perfectly spaced dominoes just begging to be upset by a spoiled toddler. The robot is nothing more than handful of LEGO parts powered by a tape deck motor. The parts may be meager, but there’s an abundance of ingenuity tied up in the design.

CES: Parrot’s AR Drone

We hadn’t been here long when we stumbled upon the Drone tent. The AR Drone is a wifi controlled quadcopter that has been making waves recently. We actually got to play with one a little bit. Well, sort of. There was too much interference inside for us to fly it manually, but we did smack it around a little bit while they told us about it. It was amazingly steady and strong while it tracked a target around the tent. Check back later for more videos and details.

CES: RoBoard Robotic Hand

Today while walking around the booths, we saw a robot hand sitting out with a couple of exposed boards. This of course attracted our attention, and we thought we would share.

The hand is based on a RoBoard Vortex86DX board, which is an x86 control board. We even got the pinouts and datasheets, and we will post those later when we manage to get them uploaded.

CES: USB 3.0 Behind the scenes

We know a couple of you have been asking about the tech behind the show, and we managed to spot an FPGA (in this case, the Xilinx Virtex 5) serving as the core of a demo between two SuperSpeed USB Solid State drives. It was used as both a USB 3.0 hub, as well as being used to time the file transfers and get accurate speed reports. The Hi Res Shot is also available.

2-axis motion timelapse photography

[Milapse] picked up a motorized telescope base a few years ago. He’s using it to add motion to time-lapse photography. The base provides two-axis rotation controlled with a handheld keypad. Custom firmware and a bit of software allow for computer control. [Milapse] is pretty well-known in the time-lapse photography circles of the Inter-web. He’s posted a ten minute video explaining his setup and programming work for the hardware.

His use of a quality camera produces some nice video.However cost at $200 for the base, if you just want to play around with the concept you might want to stick to a webcam and LEGO setup.

[Thanks Jack]

Suska open source Atari ST

Got a special place in your heart for Atari computing? Now you can quench that need using new hardware. The Suska project has achieved complete hardware emulation of the Atari ST using an FPGA. The project’s progress tracker shows implementation of the major chips at 100%. They are running EmuTOS, an Atari emulator, as the operating system because running the original would violate copyright. The chip used is an Altera Cyclone III. You could load up the code on your own hardware but judging from the number of connections needed it might be less of a headache to buy a board from these guys.

[Thanks Erik]

Spy on your office

[Garagedeveloper] sent us his custom surveillance system, part 1, part 2, and part 3 after needing a way to find out why some cables at work were becoming unplugged (spoiler, the cleaners were messing up the wiring). At the base of the system is a web cam glued to a stepper motor. However, it gets much more in depth with a web front-end that allows the user to stream the feed and control the position of the stepper. We’re not particularly fond of how many different parts the project takes, while it all could be accomplished under C# with ASP.NET and parallel port library instead of including Arduino and excess code, but to each their own and the project turned out a success anyway.

Version control for Eagle

[Jeff] set up version control for Eagle libraries and projects. He mentions that Eagle has become the standard for open source hardware projects and he’s absolutely right. We use it for our projects, and we’ve grown to expect that the posts we feature have Eagle files available in most cases.

But Eagle falls short in its library management. There is some amazing work from SparkFun to support a usable parts library, but who hasn’t added parts themselves? [Jeff] setup libraries using github so that changes and additions to the libraries can benefit all and cut the amount of time spent making custom footprints for new components and packages.

SparkFun’s Free Day is nearly upon us…

As I’m sure many of you already now, today is January 7th. While that might not have any real significance normally, today this means that our favorite hobby supplier, SparkFun, is giving away up to $100,000 of electronic goodness. We know we have our shopping carts filled to the brim, and we’re sure that most of you do too. With the start of Free Day being roughly 10 minutes away, we recommend that everyone man their shopping carts…. This should be interesting…

Fun Theory grant is 25k for a fun project

First the bad news, it’s too late for you to apply for this grant. The good news is that you can vote for the projects you think deserve money to do some good.

The Fun Theory is the group that produced the musical subway stairs and the bottle bank arcade. Now they’ve put out the call to arms on the Internet for submissions that make life more fun and our communities better places. All of the submissions for the fun-theory-award are in and available for your perusal. Some of the most popular submissions include a vending machine that uses recycled cans to play a slot-machine game, a hand sanitizer that makes funny sounds when used, and putting a giant crossword puzzle at bus stops to encourage ridership and make waiting more fun.

[Thanks Matthew][see Matthew's entry in the contest]

Max/MSP accelerometer beat control

let us know about his Max/MSP Controller. Inside the device is an ADXL 335 accelerometer and 6 push buttons wired to an Arduino. The input data is sent to Max MSP, a sequencer controlling 5 audio tracks, correlating to 5 of the buttons. The 6th button controls delay. What we really liked was how the accelerometer modified the speed of the beat in the X-axis, and the delay intensity with the Y-axis. Whats next? We think gesture recognition might be something fun to try, but [Ryan] is unsure. We’ll keep you up to date.

Reverse engineering the Telly Terminator

[Oliver] received the Telly Terminator as a gift and decided to take a closer look at it. This key fob has two buttons; one shines an LED like a flashlight and the other turns off televisions. Sound familiar? Yeah, it made [Oliver] think of the TV-B-Gone as well.

He cracked open the case to find just a few components. The brain behind the IR signals is a Helios H5A02HP. Only a few pins are used for outputs so he connected a logic analyzer and recorded the signals. His writeup covers the process quite well. He takes a known IR transmitter protocol and compares it to the capture from the logic analyzer. It turns out that the fob generates 46 different signals and with further analysis concludes that there’s a chance the code used here is from an older version of the TV-B-Gone source.

Pong, for real

Over at EvilMadScientistLaboratories.com they’ve asked a question that many of us have never thought to ask. What exactly is Pong supposed to be? Instead of assuming it was ping pong like the rest of us, they decided to build a literal physical interpretation. They may have taken some liberty, using solenoids as the paddles, but the end effect is quite nice. Watching them play actually looks both challenging and fun. There’s a great writeup about the construction, so be sure to check out the project page.

CES update: January 6th, 2010

It’s just about time for CES (as we’ve mentioned once or twice), so we thought we would update you on our latest goals and ideas for the show.

This year [Caleb Kraft], [Nick Caiello], [James Munns], [Devlin Thyne], and [Brett Haddock] will be covering CES. We are currently looking for some good places to go if we get a chance to break away from the show, and while we won’t make any guarantees, we’d love to meet some of our readers! Please direct all ideas for your favorite eatery to our Contact Page. Keep an eye on our Twitter page (@hackaday) for CES updates and what your favorite writers are up to, where we are eating, and other possible chances to meet up with us.

We are also still looking for Las Vegas Hackerspaces to visit, so let us know and we would love to cover it!

Be sure to check out our updated interest list after the break, and keep sending in what you want to see!

Pulse Oximeter

[Mike] is building his own Pulse Oximeter which uses light to measure the oxygen saturation in blood. One collateral benefit of this measurement is that pulse rate can be calculated from the same data. The parts used for the detector include a red LED, infrared LED, and a TSL230R light intensity measuring chip. As explained in the video above, each LED is shined through the tip of your finger and onto the light sensor. The IR LED is used as a baseline and compared to the red LED, which has some of its intensity absorbed by the red blood in your finger. This is a pretty approachable biometric concept so you may want to start here before moving on to more involved biometric interfaces.

Update: more pink wireless-terminal hacking

[Dave] poked around inside of an IM-ME wireless toy and compiled his findings. He read about the device when we covered it in November and picked up a couple to see what he could do. He patched into the debug port in the CC1110 processor and enabled it by performing a chip erase. He then began mapping out how the processor connects and communicates with the qwerty keyboard, the wireless radio, and the LCD screen. The board is full of test points which make the hardware easy to access. [Dave's] experiments show that this hackable device is full of potential so let’s see what you can do!

Arduino I/O Speed Breakdown

[Jee Labs] has worked out how long it takes for an Arduino to perform various I/O operations. Predictably, analogRead() takes the longest, followed by analogWrite(). Arduino really falls behind when it comes to digital pin I/O: digitalWrite() takes a whopping fifty times longer than a direct bit write to a port register! This is something to take into consideration when you are looking to do some beefy I/O with an Arduino. Perhaps this I/O performance will be addressed in the future with Arduino 1.0.

RepRap acrylic extrusion using hotbed

[Nophead] started the year off by successfully extruding acrylic using a RepRap machine. The problem when working with this material is that when the hot ooze hits the cold air the printed material tends to warp, badly. [Nophead] raised the ambient air temperature around the part being extruded by replacing the bed of the RepRap machine with a heated aluminum plate.

We took at look at his build details for the hotbed. The plate itself is aluminum that he had milled by a machinist friend of his. It looks like the heat is produced by a network of power resistors bolted and soldered to the bottom of the plate. The original idea was to produce a controllable SMT soldering platform. Unfortunately this heating method doesn’t have the power needed to raise the temp quickly but that failure turned out to be a RepRap success.
