A year and and half ago, I set out to create an RFID office chair that logs me in and out of my computer automatically when I sit down or get up, using a strategically placed implant in my backside.
Well, at long last, here it is:
What you need to create this:
- An office chair with a RS232 ACM08Y long range reader bolted to the back:
- A Linux computer running SiRFIDaL:
The flexEM has roughly a foot of range with this reader, and reads across the entire surface. This means I can twist and turn on the chair, slouch or lean forward and the reader stays latched onto the chip no matter what.
Now, I probably should make it wireless and battery-powered. The serial-cum-power cable running from the chair to the computer doesn’t look great. But I don’t really move that much in that chair, so I never run over it with the casters. I may just keep it as it is.
I love it when a plan comes together
