Whizzer - PhotoVore's.
Now this one is really fun. Whizzer seems to spin around and
hide in the dark. Once it ran itself under the stove and just stopped
there, sitting, waiting, not moving. Whizzer is so fast, it couldn't
be caught anyway. It does not have a whisker as yet, but seems to
back up all by itself. I had a lot of laughs with this one.
Just before going into Taco Bell, it was put on the top of my car's roof.
It almost jumped off into the parking lot, but stayed there and looped
around and around heading toward the back window.
Whizzer's weight closes the switch to keep it going, but stops when
it is picked up. This saved the trouble of a slide or toggle switch.
There is paper between the two switch contacts to stop it from running
when it's posing. This switch breaks the '0V' wire, the one from
the batteries to the photovor1.
The batteries are 2 cells from a 9 volt battery, just under 3 volts.
Tires: First a layer of wire insulation is installed, then a short
piece of plastic tubing is put over that (Thanks to Wacky Willy's, Beaverton).
Here are the pix, click for larger ones.

Tires are now that clear plastic tubing, much better.
The back leg (slider) is soldered to the switch. Just set it
down to turn it on.

It has yellow paper in the switch to make it sit still for photo shots.
Close up of switch and left side. In the larger pix, you can
see the floor lint wrapped around the pager motor shafts.
