I've also made some Ultimation Fader Test Jigs. I have four available for purchase. These are very much a prototype, but still helpful when testing faders and not having a console at your side to test.
A purchase includes the fully populated PCB, +24V DC power supply for the board, and a programming cable should you want to alter the arduino code.
I am going to price these low at 150USD plus shipping. I only have 4 in stock. Not planning to do another run unless there is more interest.
Here's a video of the test jig in action,
