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.
