How to get a start in using C and not bootloaders

Hello there lmr, I was thinking that it would be best for me to learn some C and program micros without using a bootloader (happy now krumlink?). I was wondering where to start. I am not trying to bring up a debate but i was wondering if PIC or AVR was better to start off with? Which one is easiest to use and which has the better programming environment. Also what would be needed to start in PIC or AVR? I know a chip, board, and programmer, any thing else? Or any thing else you can think of for someone trying to get into this.

Anyone have experience (good or bad) with Tayda electronics? Please share.

I just googled this one part and Tayda came up as the absolute winner on price. Who would like to teach me how to order small quantities from suppliers far far away. Any caveats, consumer traps, unusual conditions, broken promises?

B5 progress

Whatup gays,

Calculon just wanted to drop a line and share his progess on his B5 (the Backyard Beverage Buddy BBot) project. He started his project last fall as his entry into the XMOS challenge. The idea is basically a cooler on wheels that rolls around Caluclon's backyard and offers beverages to people. That's still the general plan, but the scope has changed slightly.

B5 1.0 features the following:
