Ciseco

An assortment of radio boards for use with Arduinos, Raspberry Pis and the like. They're based on the CC110x chips so they're pretty flexible (e.g. they do one with a built-in USB controller, and an Arduino clone that uses that to do the USB serial port).

FT240X

Like the ubiquitous FTDI serial chips, but with a parallel FIFO interface. This'd be ideal for getting data efficiently off of older machines.

Mele A100 | Arch Linux ARM

Allwinner A10 ARM machine, widely available for not very much money. I'm half-tempted except that fortunately I don't really have a use for one.

Computer Laboratory: Baking Pi - Operating Systems Development

Bare-metal programming on the Raspberry Pi board. This is what we'd need to get RMoX running -- probably a worthwhile experiment at some point...

Debian HOWTOs

Installing Debian on various embedded machines. The SheevaPlug might be what I'm after; it's slightly more expensive than I'd like.
