Re: gEDA-user: Design Lab Equipment
To add my 0.02 CDN...
I have a couple of NXP LPC2103 based boards that I have been using. They cost me $24.95 USD from www.futurlec.com. These are ARM based and I use GCC (with the patches from www.gnuarm.com, which you don't really need unless you want to mix ARM and Thumb code) to program them. They also have a built in ROM bootloader so you don't have to mess with JTAG to program them.
NXP has plenty of example code to get you started, and I wrote a simple command line downloader for it that runs under FreeBSD, but should compile on Linux without any changes. .

I second this motion! basic stamps have nice small simple boards,
the drawback i have with them is I didn't want to learn another
variant of basic.....
If you are familiar with C I'd suggest a microcontroller that is
capable of being programmed in C, assembly can be tighter and
cleaner, but that takes practice.
I am fond of the Atmel AVR series, and the GCC tool chain that goes
along with it, it is also convient for OS X and Linux users, as the
basic stamps native environment is windows.
yes they have compilers and such for linux, but the AVRs have better
OS X support. With the GCC tool chain you have the ability to use
both assembly and C
I have seen DJ Delorie using the R8C from Renasas, and I see that
they are also using a GCC tool chain. They look like a nice part as
well.
Happy researching
