Break a leg, Wild Thumper!

I experimented a bit with video. The weather was perfect for it, as reported earlier.

One laptop with webcam streaming live from my balcony to ustream.tv. And my little 10fps camera on board. Then fool around until the batteries run dry.

Afterwards I found a problem in one of thumper's "legs". It limped. Exploratory surgery confirmed the great fear: a gear is missing some teeth. Oh well, we'll always have the photos.

RF link TX/RX 434 MHz = lessons learned and then some

I'm trying to build some sort of RC transmitter using the 434 MHz radio link set. Sometimes called Easy Radio, but not by SparkFun. Edit: because they're not the same thing!

I am setting this up on a breadboard with a Picaxe 08M and two potmeters as inputs. The two ADC bytes are combined into one byte. The one byte gets transmitted.
