Hack a Day has great articles about hacks from all over the world. This time I want to write about a very interesting project about radio controlled lawnmower.

I wanted to build similar lawnmower with the difference that I would use Wiimote for controlling it. But interfering Wiimote directly to an AVR or other micro controller is a bit hard, so I thought of using the laptop to connect Wiimote to a mower. I already made some plans, but then I realized about the biggest problem - danger of using something like this without my direct control over it.

After all, I'm perfectly capable of hurting myself without additional help, so building this could end badly.

Anyway I'm happy that someone actually made something like this, and I have no problems about him using it as long as it's far away from me. :-D

I stumbled upon an interesting article about wireless transmission of power and thought of sharing it here.

It's really simple and cheap way to wirelessly transmit electricity on really short distance. It's made of big and small coil, a couple of capacitors and LED diode.

I'm interested in omnidirectional wheels from when I watched Prototype This!, The Discovery Channel TV series. They used these wheels in episode Six-Legged All Terrain Vehicle.

I thought a few times about building a RC car with these omni wheels, but never got around to even buy needed materials. And of course there is also a lack of tutorials/articles about it on the Internet.

Well, I then forgot about it, but a few days ago I found a post about Omni-car on Hack a Day blog. http://hackaday.com/2009/11/17/omni-car/

Really interesting project, but sadly these wheels are a bit too expensive.
