This one fits firmly into the hobbyist category, but a bloke on a set of message boards has managed to create a little mini-Segway using parts worth about thirty quid or so. All it consists of is some Lego and an Arduino.
What’s an Arduino? I’m glad you asked. It’s a pre-built circuit board that you can plug into your PC via USB and, with a little bit of programming, will do all kinds of crazy stuff. You can hook up other components, like accelerometers, GPSes, and sensors, and do stuff like ringing doorbells with Twitter or making mini-Segways.
I’d not heard of it before, but as soon as I saw it, the geek light in me started flashing, so I’ve ordered one (A “Diecimila” for £20, not too bad) and will give it a shot. If I’m able to make anything good, I’ll let you know.
Are you an Arduino user? Got any tips for an Arduino noob? Have you made any cool Arduino projects? Drop us a comment, or email us photos and/or video. If it’s awesome then we’ll cover it.
