seeking help with drumbot (robotic drummer)

...

Don't know about drumbots, but Alistair Riddell at anu's sound art &
physical computing might have some pointers.  He build at least 3
solenoid-controlled pianos over the years.

You might try looking for places that sell parts for pinball machines.
One machine uses a few of them and they are a fairly high failure item.
They used to be inexpensive, but that was a long time ago.

Good Luck,

    --FWIW I've messed with solenoid valves for a Stamp calliope; one
would imagine bare solenoids are cheaper at least. If you need a dozen or so
ebay is your friend: got my valves for 1/4 retail price.

I haven't made one, but Here are few choice sources.  A lot depends on how
much force you need.  Some of these won't have any specs.  However, the
general energy formulas apply. Energy in = energy out.  Also, be concerned
about how much current they draw when actuated for more than a brief time.
They act like a short, with a low value resistance.

Can you tell that I am unemployed and looking for things to do!  If anyone
is looking for a CAD expert with machine design experience, please contact
me.  I am in the Eastern PA area, but will also consider moving to central
& eastern GA, or central& south FL.

I wonder if the aftermarket electrically-operated trunk releases might
not be a really good source for solenoids....
