Custom 1 CH DigiSpark

[drigotti]

I was looking for a tx arrangement to operate the throttle on my new F2G electric speed plane (control line). A few emails to and from Phil Green and I had my solution. A custom programmed and prewired 1ch DigiSpark board. I coupled it with the Lemon rx DIY tx module and the results are EXACTLY what I wanted. A few hours designing the case and 3D printing produced what you see here. I especially like the "hidden" antenna!
Phil provided a single green color wire to calibrate the throttle knob. During calibration it is grounded to any black wire coming out of the module. If you look closely you can see a single header pin soldered to the pots black lead. I simply connect the green wire to it for calibration. No trim function is provided nor needed. A buzzer is provided to warn unit is on after 30 minutes operation. I added the green LED with a 390R resistor in series that is hidden in the long black heat shrink tubing on the left. TX case is 110 by 60 by 30. I used Tinker Cad for the design and printed on my Bambu P1S 3D printer.
Thank you Phil!!!
