Eye tracking via electrical impulse

_eyeball_movement_electric_sensor (Custom)

Generally when tracking eye movement we use various methods that require sensors being pointed at the eye itself. This approach is quite different in that it is sensing the “electrical potential of the cornea”. We have no idea how this works, but it looks pretty cool.

1964 300baud modem surfs the web

[phreakmonkey] got his hands on a great piece of old tech. It’s a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to see if it would actually work. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn’t working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It’s still amazing to see this machine working 45 years later. He’d love to hear from you if you’ve used a similar device.

CandyFab relaunched

Forget about machines that can replicate themselves, what we want is a machine capable of making an 8 inch wide hollow torus out of sugar. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the new wiki site.

CATaLOG: RFID cat tracking


Like many pet owners, [Pete] was curious about his little furry friend’s habits while he was gone. He decided to build an RFID tracking system to monitor their positions. This data would then be available on the web.  An Arduino handles the communication of the data, both to twitter and his personal cat tracking site. We were a bit surprised to see that the only data transmitted on the final project was whether the cat was inside or out. We’d like to see a heat map of the cat’s activity in the house.
