This is actually my very old idea, but I never knew how to realise it since I`m not some electronic genious..
This is another great midi project based on PIC, and I wonder is there some ideas how to interface electromehanics with midibox. I know there`s a way to put relays (probably too slow for this purpose) on a digital out modules, but can you somehow send midi signals from sequencerĂ to transistors which drives the motors, electromagnetsâŚ
I get inspired aboutà interfacing drum over midi when I first time saw automated piano with rorating drum with mechanical trigers on it. Imagine to put little beaters on a diferent kind of junk⌠cans, boxes, real drums on a stage and sequence it in a backstage. If you make fast beaters that react quickly it could be more then usefull.

I think Darlington transistor arrays are faster than relays, and the DOUT module even supports these ICs directly, the output pins become high current sinks instead, so the negative pins of all your mechanical stuff is connected to the DOUT pins and the positive pins connected to whatever supply you want.
Didnât you already do stuff like this with old hard disks?
theres something faintly disturbing about the fact that the nudists association managed to claw their way in on such a topic..
conversely, if like one chap i knew.. you take up photography & drawing classes in the right places ..youll have quite a legitimate excuse to study a varied range of fine & inspiring curves.
The time delay from setting an output to actually beating the drum is easy to fix, especially using a sequencer in a PC.. just time shift the percussion tracks forward.
Of course then itâs no longer interactive, but only useful for pre-recorded sequences.
In the interest of being polite, Iâm not going to make any comments about Sashas friends (or family)
relais⌠? maybe transistors ?
