At this point, more theoretical than practical.
Most TX's use 5V technology, Microchip has a nice 8PDIP, 10K, 256 step, device, the MCP41010, that will happily run on 5V.
If this were to replace a slider or pot on a TX, you would be able to hack any brand TX, even with limited tech skills.
So, this is an attempt http://youtu.be/20tISVKXImE
And the code is here, just begs to be trimmed down by a qualified code monkey :-)
Hope to have some PCB layout this week........
