The two analog organs are still in the garage. Well one is. The other is now mostly MIDI-fied. As I think I wrote earlier, I ran into a few tricky spots, the last of which was my attempt to install the oh so important swell controlling variable resistor.
Most electronic organs use a rotary resistor, but the range of motion is not really compatible with most commercially available rotary resistors. And if you choose to use a linear resistor as I did, things get even more interesting.
I tend to obsess about details, so it was easy to get bogged down in prototype building. The ideal solution will probably eventually turn out to be use of a 3D printer to create the desired support for the linear 10k potentiometer, but that means money and/or time. In the meantime, there are some more straightforward solutions. Here's one way to do it:

or even simpler:
You will note that some of these contraptions tend to require a bit of 'elbow room', which I am trying to minimize. I also am trying to recycle the original Rodgers Swell pedal mechanisms, so obviously things got complicated fast. Stay tuned for progress and feel free to post your suggestions.
