I don’t want to tip my hand too soon, but there’s a few things about WordPress that I find myself writing code for that, really, I shouldn’t have to write code for. Especially since the foundations of making things “just work” are all already in WP, and in most cases, have been around for quite awhile!
I broke down and ordered an Arduino (ok, the Freeduino SB, specifically) from HVW Tech. Piece of advice - to save on the $5 handling fee “on orders under $30″ — add an L293D motor driver for to your order for $3.95. You know you’re gonna need one anyway… 
So, I ordered a PICAXE 28X1 board from Advanced Micro Circuits (aka World Educational Services), and it arrived yesterday. It’s a bit smaller than I expected (which isn’t a bad thing at all!), but it was also sans-interface cable, which was a bit of a let down (the cable is, however, en route!). Either way, it’s a compact microcontroller package with a decent feature set, so I’m looking forward to playing with it. Fits inside an altoids tin, sans-batteries, and I suspect with a proper LiIon pack, it’d probably fit in the tin with batteries. We’ll see… 
It was up against the Freeduino SB (produced by Solarbotics / HVWTech, a derivative of the Arduino Deicimila board), which probably would have been my choice had I done some more research up front. The Freeduino SB is a bit cheaper, mostly due to the fact that it ships as a semi-kit where only the SMT components are pre-soldered, and the rest of the assembly is up to the purchaser, but the trade-off was that the PICAXE was built with the capability to add a motor driver by simply socketing an L293 into a slot on the PICAXE board — the Arduino would require an external circuit. What I didn’t know, was that Adafruit sells a motor driver “shield” for the Arduino for just under $20.
Someday I'll fill this space with meaningful, personal information. Today - is not that day.
