|It's just because I hadn't quite decided on the mapping, and I'd like
|the flexibility to play around with it as I see what's possible, but
|this is what I've got at this point:
|Input Ohms Output Ohms
| 82 23870
| 164 17030
| 284 2223
| 464 12270
| 794 8950
| 1474 6730
|I'm sure the resistances on both sides have some give in them--they're
|measured values and obviously aren't standard, but that's part of what
|I'll have to figure out as I tune this.
|One thing that's clear is that there is no relationship between the
|input and output numbers, so it can't be a simple amplifier-type
|solution. I agree with Phil that a microcontroller would give me a
|lot of flexibility, but I also agree that it's a bit more work than I
|had hoped for (and this is definitely a one-off application).
I thought, in your original post, you mentioned that more than one
switch could be pressed?
