Shawn White - Carrot Top - Raggedy Ann look alike?

Anybody notice that Shawn White (US Snowboarding olympian) looks like Carrot Top (US comedian)?

20Amp Motor Driver/Controller

I am looking for a 20 amp motor controller/driver. I prefer an IC, that way I can integrate my own driver circuitry, but if it is cheap (under 50) post it. I'd prefer if it could provide 20 amps per channel. It will be operating on 12VDC.

Maze Solving Robot Progress

Updates

Progress on my Maze Solver:
Mainboard: Schematic Done, Board Layout Done
Sensor Board: Schematic Done, Board Layout Done
Programming: Haven't started
CAD: Done!

Finished the sensor board, took some screenshots of it in cad, added to attachments.

I will package all necessary files in a zip so anybody can build this robot. I just recieved the PCB materials today, so hopefully tomorrow (Jan 19) I can etch the boards and start assembling the robot.

Audible click coming from Maxbotix LV EZ1

Just got my sparkfun stuff today, and while testing my Maxbotix LV EZ1, I can hear a faint clicking noise a few times a second. Also, the Analog values seem to be completely inaccurate. I think the accuracy may be with the Power supply (ATX computer psu). The clicking noise can only be heard when the sensor is pointed directly at my ear. The sample rate of this sensor is 20Hz, so I know it shouldn't be the sampling device making the noise. Any experience with this strange problem?

Coil Gun Rifle

I have been making soem good progress on the Coil Gun Rifle:

Arc Point Art

Well, I had some fun in the attachment. I would take a sheet of flexible circut stuff, and charge my 24Joule Capacitor bank. i would then short out the points between the plate and the wire, vaporizing the copper at the point, creating a black spot. In the attachment, I spelled KL!, mostly because I diddnt have that much to mess with :)

 I was thinking of doing LMR next :)
