[Sleepydog] just sent in this cool video of a patch cable he made with a built in EL wire. He’s using a Power over Ethernet router to control which ports have power. He states that this would allow easy identification of specific cables in the mess. While the proof of concept seems completely functional, and the idea is nice, we have to wonder if the cost to put in all the extra hardware would be worth it. Each cable would have to have its own inverter, not only driving up cost, but possibly adding interference. That does not mean we don’t want this desperately, we do. But we want it just because it looks cool. He needs to choreograph this to some music now and make his entire server room into a fancy display.
In an attempt to create an easier to use interface for the elderly, [Stephen] has put together this phone prototype which uses RFID tags to dial. It is common for our motor skills and eyesight to deteriorate as we get older. There are special phones out there, but generally the only changes they make are enlarged buttons and louder speakers. [Stephen] had the idea to make a system where an elderly person would hold up a picture of the person to the phone and it would dial. He picked up an RFID card reader and an Arduino. The code for the RFID reader was already available, and with minor modifications to prevent multiple swipes from hand tremors or slow movements, he was able to get it working pretty fast. The Arduino then sends the data to an ioBridge to make the call.He’s using Google voice to physically place the call, so you could probably adapt this to other services as well. You can see a video of it in action after the break.
