Look through some of the things I've made, remade or I'm still making.

Why bother buying something that's exactly the same as everyone else's when you can spend a few hours* making something unique for next to nothing?

If you do part with you pennies on some new gadget don't you just want to get a screwdriver to it, invalidate your warranty and find out how it's made? If you can't open it, you don't own it.

These are the thoughts of Mr. Maker.

*OK, the Log House took a bit longer.

I've been making some motor controller circuits using components taken from scrap computers and video recorders. These are for an ongoing project but first I thought I'd test them on a robot (also made from junk), so the result is ArtBot. This robot has dual H-bridge controllers for the DC motors, 2 servos, a bumper switch and a light sensing circuit.

Experience has also taught me that easy access to the OFF button is essential when testing robots.
