I have been working on this for an embarassingly long time. But yesterday I simply decided it was time to finish it, so I did.
It's a "data glove" or maybe more accurately an "input glove". It captures what each of my fingers does with five individual slide potentiometers, for controlling some other mechanical device.
That "other mechanical device" is not built yet. And the fact is that it could really be almost anything with five functions, like a mechanical hand or a four-legged robot with a flamethrower.
