My son aidan and I have been working on a pair of arduino based robots. Today I had him look at the boards from the check reader pile and reverse engineer the emitter detector pairs that tell the reader when the check is present. After poking around at the circuit board he came up with this diagram. Which we distilled into this circuit.

I was making a set of paper encoders to attach to the wheels but aidan thought it would be better just to use the holes in the gears After a trip to the hardware store for some epoxy putty to sheild the phototranister, I put two pair in each of the Tamaya Wall Following Mouse based robots and bench tested them with an arduino.

Finally, I get my drawing from two days ago up.  This is my Victoria’s Secret bot, version 1.  She’s just a prototype, that’s why she doesn’t look too happy.

Day one, and I’ve got nine minutes of my lunch break left.  I got my first robot portrait finished and scanned.  Enjoy.

I’m still going to pick up trash, since I do that anyway, but I think I am going to draw as my daily thing.  I’m going to do Robot Portraits.  I did one of my friend Mark and it came out cute (I think).  I may have it in a postable format.

He misspelled “portrait,” not me.
