Of particular interest are the 28 pin DIP versions of the PIC32 (a MIPS based CPU) as well as the ARM based LPC1114FN28 from NXP. Both of these can be used on a breadboard without needing a module or a development kit which makes them very well suited for hobby level projects. I have samples of both of these chips and I'm experimenting with using them in my competition entry.
In the meantime I'm partway through a little weekender project which I'll write about tomorrow. I'm very happy with the way it's shaping up so far - I can't wait to show it off.
