Well I am waiting for my version A.5 picaxe and got an idea for this little guy. He is not fully done yet but getting there.
Stevie is a BEAM bot/Solar Roller. As you will see in the video I need to get him a good propeller from a hobby shop. And he is only under a 100 watt bulb. In sunlight that motor will move pretty fast.
It only cost about 25 bucks to make him.
The solar cell is SCC3733 from solarbotics.com
The base is made out of expanded PVC.
The wheels are 9mm rubber.
The back has a small metal caster on it.
The motor is from a broken Sony cell phone.
Green small LED for the head light.
I used the wire that came with my picaxe board since it was small enough. I just pulled each cable free from the ribbon.
The propeller is a home made one from cut up twisty ties. lol I cant wait to find an acuall small propeller for him.
