Drunk as always, but again pretty ingenious and simple ! 😆

hey lets pore whiskey on this tape and see how it sounds , yeah he comes up with some off the wall crazy shit but its fun to watch and I bet he’s a hoot to hang with in his shop .

No question about that !! LOL

He reminds me of a close friend. Let’s make a guitar, but string it with spaghetti.

Was actually thinking of attaching one to the Mikrokosmos module.

And I thought :
“Now I need a Mikrokosmos… it has it all, even the screw for attaching the stop”

Here’s a couple of Mikrophonies outfitted with springs. There’s also the interesting idea of having the modules lying loose across the rails of a skiff, and “playing” them by moving them around.

I can’t see any reason for connecting a wire to the stop.
The piezo picks up mechanical vibrations from the stop, nothing electrical involved in this interface.
But it can’t hurt…

interesting using it for CV control .

thanks , it just looked he did that, I know the other way would work, I was just seeing where the best aural placement would be , knowing the stop is not an electrical element

definitely see piezo is past stop and only attached to jack , thanks again. Us superthinkerbuilders over look practical things , dont we?

Okay so the doorstop is pretty fun. This is maybe ten minutes after hooking it up:

It’s great but I think it needs an actuator. Imagine a CV-controlled solenoid that gives the door stopper a good ding whenever it receives a trigger.

than a robot to trigger the the actuator …

I was thinking the synth signals could trigger the actuator. That’s a kind of robot I suppose.

And then a Nintendo controller to control the robot.

I love this. I love the look of the Mikrokosmos with the doorstop.
But I might instead play with setting up a doorstop with piezo as an external thing to plug into the Mikrokosmos…
