My Focuser Build This focuser build is for a Skywatcher Equinox80 ( no longer manufactured) and can also be adapted to the Orion EON80 I wanted a compact controller box, the usual positioning of the Arduino on the board did not allow that (couldn't find a USB mini T connector) so I redesigned a board with the arduino turned 90°. I enclosed the Fritzing file. The Board has the following options: - OLED display - Home Switch Position - Rotary Encoder - Temp probe - Power on reset / flash I chose to mount the rotary encoder and the connectors for the temp probe on the motor bracket so used a DB-25 instead of the usual DB-9. This allows to have an integrated system on the scope and be able to use the focuser 'naturally' when using it visually (TBH I liked the moonlite NiteCrawler setup - I could've gone one step further and mounted the display too) There is provision for LEDs but I chose not to mount them, there is the power LED though that illuminates the On/Off switch Most parts are sourced from Amazon and Digikey with some extras from a local Fry's. Inspired by pipshag's bracket I decided to print my own and enclose it, I attached the FreeCad file. As at first I didn't know if I was going to source OLED or TFT I chose to merge the 2 different source codes into the Focuserv270_DRV8825_HW203.ino file. Be advised that not all sanity checks for exclusions are well done but it works on my OLED setup.
