Handwheel 3.5" TFT for Estlcam
thingiverse
This handwheel is based on s_fr`s great work: https://www.thingiverse.com/thing:4126582 Due to better visibility of the display and a cheaper rotary encoder I modified it to my own needs. I designed a new housing matching to a bigger 3.5" Nextion TFT (NX4832T035) and also added a hole for 9-pin sub-d-plug. Pushbuttons are 12mm momentary switches, I`ve used illuminated (3-9V) ones. The handwheel comes in two versions. Regular (single colour) topshell and dual color topshell. The bottomshell fits both. Firmware for 3.5" Nextion is in the included ZIP-file. Copy firmware to a sd, insert sd to the TFT and power it up. Wait till TFT is updated, remove sd and restart the TFT.. For further informations, schematics, firmware for arduino leonardo etc. see original design.
