uBITX Remote Head with 3.5" Nextion Screen

thingiverse

This is a remote head housing for the uBITX HF kit using a 3.5" Nextion touchscreen. The RF board and Raduino of the uBITX are housed in a separate enclosure, pretty much of your own choice. Although I have made a front plate adaptor for my old compact uBITX case design, details on that are on the old design's page as a revision/addendum. This page will focus only on the remote head. Link for the main box with the RF board and Raduino: https://www.thingiverse.com/thing:2925336 Instructions on how to replace the Raduino firmware to support Nextion screens and how to load the GUI to the Nextion screen: https://www.youtube.com/watch?v=hhQkF18Vpho Materials needed for this remote head are: - 10k volume potentiometer with a 17mm diameter housing, a 6mm diameter by 11.5mm long teethed shaft (same as in the compact case) - GX16-n microphone jack where n is the number of pins (same as in the compact case) - 3x 5mm ultrabright LED bulbs, your choice of color for the knob rings backlight - 8x M3 3mm machine screws - 3x M4 4mm nuts and bolts Optional items: - 2x 3mm red and green LED bulbs for extra TX/RX indicators - 50mm, 1watt minimum speaker - 2x 3.5mm stereo phone jacks - DB25 25-pin D-sub connector and 2x M3 3mm nuts and bolts The remote head contains a 3.5" Nextion screen, the VFO knob, the volume control and mic socket of the uBITX transceiver. Interface to the main box is via a shielded cable, whose number of conductors will depend on whatever you want hooked up in the remote head. For this reason, I have chosen a DB25. It's cheap, readily available, and has more than enough needed pins. And I reckon there are loads of serial cables lying around doing nothing. If you want to hardwire directly, I have included a cable thru plate for 6mm, 8mm, and 10mm cables. The knob rings should be printed at 100% infill with clear/translucent filament for best light transfer. Everything else at 20% infill with the filament type and color of your choice.
