Another option would be to use something like an iPAC four And connect the individual keys up to a terminals.  Or use the UHID board.

Re: Hacking a Bigtrack

<t>If the bar magnets are attached are attached to the axle, then I guess they rotate. If they rotate then a simple coil could be used to detect the magnetic pulses that occur each time the magnet passes. The circuitry is quite simple, to then turn the current produced into something meaningful.<br/...

I did a clock in Java once. But that was years ago, so probably not much help on the Java front I'm afraid.

Re: GPIO and TTL serial

Its been a long time since I've done any real serial ttl stuff so a little rusty. Am I right in assuming the RX and TX pins on the GPIO are actually ttl serial.

I really hope the answer is yes, as I have a couple of potential projects that use a TTL serial interface for coms.

Re: Freedomotic Home Automation on Raspberry

At the moment I am still waiting for a PI.

I have the following x10  interfaces  a CM11, a CM15 and an XM10. The CM15 has a USB interface. The others will need a serial to USB converter.

So I can test with a wide range of interfaces.
