Audio volume of a Synth can be easily controlled via LDR-LED (Morley Vol pedal), but I prefer to control the Vol via lateral/ horizontal hand movements to create Vol and tremolo variations.
I discovered that there exist a $200+ gadget, called "Hot Hand 3", but I think the same effect can be achieved more economically:
How about using a tiny mercury glass switch, found in Chinese "Driver Anti-Sleep" devices, here: **broken link removed** I have a couple of these. Of course, they only turn on and off, but at least the liquid mercury allows me to shake-switch and so, vary the turn on & turn off events via lateral hand movements.
Of course the volume should not just abruptly turn on or off, but rather trigger varied, smooth volume swings.
I'm thinking of a simple circuit, based on an electrolytic, which softens and briefly delays the mercury switch's turn on and turn off events.?
That way I could build it into a tiny box and attach it to a ring on my finger.
This would allow me to rapidly shake the mercury switch horizontally and thus, create the desired volume and tremolo variations.[/u]
