Xerox ink will print circuits
Saturday, October 31, 2009
Xerox has announced a breakthrough in printable circuits. They’ve developed a conductive ink called “silver bullet” that can be printed on many different types of substrate to create circuits. The key part of the new ink is its lower melting point. Plastic film substrate melts at 150 degrees Celsius but the ink is liquid when ten degrees cooler to avoid damaging the film. This begs the question: how do you then solder components to the circuit?
The benefits of printable circuitry are obvious. Aside from cheaper and easier RFID, disposable circuits like greeting cards, and fabric-based electronics, we’re hoping this will facilitate more environmentally friendly PCB fabrication. That really depends on the ink’s production process and the resilience of the resulting circuitry.

When it comes to keeping up with blogs and other websites, a common complaint is information overload. Even if you subscribe to receive site updates through an RSS reader, it’s easy to wind up with more items in your reader than you have time to actually read. You may still want to read some of those posts, but if you don’t want to read all of them, searching through your reader for the important news items can be almost as much of a burden as going from site to site.
Because of the ongoing concern of information overload, many people who previously relied on RSS have drifted away from it. However, RSS readers are evolving to solve these issues and improve their usefulness.
