As you can see in the photo of the monkey under construction he sits on a circular ply board that is attached to a bar the other end of which runs in a gear-driven eccentric self-aligning bearing which rocks him with a circular motion. This motion is continuous and draws attention to him. If a coin is inserted into the slot he raises his hat, wiggles his feet and raises a notice from a slot in the base which says ‘Thank You’.

A couple of things found (a Topsy, for example, “runs for 7 hours on a 12 volt 30 AH battery“):

1. http://www.mark-ju.net/bike_ride/equipment/charger.htm charges stack of 6Vs
2. For about the same weight as a generator setup, you could get a solar charger that works whether you
   are pedaling or not. Batteries.com has one that weighs .28 pounds and will charge 4 AAs in “as
   little as 12 hours of direct sun” and costs 20 bucks.

D says re controlling barrel organ valves using MIDI:

Could probably do that very neatly using micro pc like a gumstix
No need for hard drive for midi files - use flash memory. Power it off solar/dynamo, probably.

Do I want something like this? You bet:

Let us put men and women together
See which one is smarter
Some say men, but I say no
The women got the men like a puppet show
