Breadboarded Beam Pummer Circuit with Solar Cell

A new version of this pummer circuit, but with the solar cell installed. Low and behold, it worked the first time! I soldered it up, plugged it in and the LED pummed; then I aimed a flashlight at it and the pumming stopped.

 

See the notes on the previous photo for the rest of the details.
