New controller board

Hello, it's been a really long time, since I last posted something on LMR, but now I've made a new controller for my robot and I thought I'd blog about it.

Tiny adventures in motor control

Since my last blog entry about using timers and interrupts on the Atmel Tiny 26P, I have put together a driving lego monster with homemade dual h-brigdes that in principle should be able to eat something like 25A or so - of course the wires used are not able to carry that much current but hey I only had those IRF540 and IRF9540 hexfets lying around :-).The controller is still the Tiny26P and my goal is to make this my I2C enabled motor driver for later use with other stuff.

Fun with timers and interrupts on Atmel Tiny26

A long time since my last post on this site... Anyway I've been experimenting a little with my Atmel Tiny26 uC today using AVR Studio 4 for development and the AVR ISP mkII programmer to program the uC.

AVR is in the house!

Last week I purchased the AVR ISP mkII programmer for the Atmel AVR series of chips and I had previously bought some ATtiny26 chips for use in motor controllers, line sensors, etc.
