Social Button Device: Sputnik?

Some days ago I had the pleasure to celebrate my friend Remmelt’s birthday with him. I met some interesting people there and I also got to know the Sputnik that Sascha brought from this(last) year’s 23C3:

It’s an RFID transponder, i.e. it will work both as a sender and receiver, has a touch sensor already implemented and a tiny but programmable microcontroler onboard. So it looks like the perfect solution – unfortunately programming it is not within my range, at least for this moment (RS232 serial protocol and unfamiliar MicroChip PIC16F684 microcontroller) . Let’s see what ideas we will develop to build our prototypes…


Larissa found a very nice site that explains everything about the PIC and about RF communication as well. It’s the web page of Tom Igoe (surprise, surprise)
