After struggling with the ‘245 for some time, [James] decided to swich out the BEAM circuit for a Picaxe microcontroller. The Picaxe can only sink or source about 20ma per pin, which is slightly ...

It uses the classic seven segment displays, a PICAXE microcontroller and works with most engines. He’s released full source and PC board designs to boot. This looks like a great little ...

For those interested in the electronics side, you’ll need a few key components: the 9g mini-servos, the SD21 servo driver, and the picaxe 18x microcontroller. These components can be sourced ...

like a PICAXE 18X Microcontroller and a whole 96 bytes of RAM to address (though have no worries, Chris is planning on boosting that to a spankin' 8K before too long). The whole thing runs on ...
