You see, I’m making a laser guided car for the sixth grade Science Fair. There will be a track built up of mirrors reflecting the laser into a guidance for the car. The laser will hit into a phototrasistor, telling it either to turn right, left, or straight depending on which “eye” it hits. The funny part will be that the car will be wearing sunglasses to block out UV light that will completely malfunction the car. Also, the mirror stands will contain a lower elevated infrared LED that will tell the car wether to turn left of right. ROBOTS ARE AWESOME!!! :>)I almost have the main control circuit finished.

I work at a radioshack in Westland Michigan and during our store renovation I took home one of the ipod plastic tube signs. My friend has an ipod so I gave it to him.  I got creative and took some logitech speakers and a bunch of wires and made him a hanging ipod docking station. this things cool. I plan on adding a blue neon light to illuminate the sign at night, and I’m thinking of adding a pull chain on/off switch.

I think it would be awesome if you posted a how-to on making an electric bb/pellet minigun, possibly with a turret. (more…)
