The Spud Clock

My daughter asked for a new alarm clock....something funny and without batteries.

Her wish, my command: I took a cheap digital clock and wired it to two serial connected potatoes.


Found this neat clock online.

Two spuds, 2 copper pins and two galvanized pins are generating the juice.

Right now we are trying to find out how long the clock works with one
spud charge. And is a "Russet Potato" better for the job than a
"Larette Potato"...only time will tell.
