NXT Mindstorms

Doing a side project to help out in the job at the moment for a christmas thing, and getting to play with the new NXT mindstorms kit as a result (I only used the older mindstorms kit before now in TCD). They’re much beefier on the inside, the sensors are much more polished-looking, Robolab has come on a long way (but is still a wussy way to program these things, wish I had time to blast an open source firmware to the brick), and they’re even faster to get up and running with. In 20 minutes, I had this built:

The ultrasonic sensor is a nice addition to the kits – stick that on a servo mount and you’d have a 360° sensor for mapping your environment… albiet a really noisy crappy one 😀

Ten minutes later I had Robolab installed on a WinXP virtualbox on my Debian-running laptop (sweet how far we’ve come – in the old days, I’d just have to dual-boot to get usable performance like this), and ten minutes of fiddling later, I had taught my new robot to fear me…

(You have to teach them to fear you first, otherwise they’ll turn around and shoot you in the face…)

Snow in Dublin

It’s getting a bit chilly out there. Last time it was this cold this early in the year was 25 years ago. What was that about climate change not existing again?

(edit: Some of these made it into TheJournal.ie…)
