This is a retractable SimHub compatible race flag designed to be mounted behind a C49 Samsung ultra-wide monitor. The retraction mechanism - in this case - is controlled via HomeAssistant (ESPHome).
For the raceflag the following BOM is required:
- 1x Arduino Nano
- 1x 8x8 DC5V WS2812B LED Matrix
- 4x M3x20mm screws to mount the back plate
- 2x M3x8mm screws to hold down the Arduino Nano
For the retraction mechanism the following BOM is required:
- 1x 28BYJ-48 5V DC stepper motor + ULN2003 stepper motor DRIVE MODULE
- 1x NodeMCU Amica Modul V2 ESP8266 ESP-12F or similar ESPHome capable board
- 4x M4x25mm screws to mount the mechanism adapter onto the flag's back plate
- 1x M3 nut to mount the toothed rack to the mechanism adapter
- 1x M3x8 screw to mount the toothed rack to the mechanism adapter
- 4x 4x16 screws for the mechanism lid
- 2x 3x35 screws to mount the mechanism onto the stepper case
- 4x 3x20 screws to mount the stepper case onto the monitor mount
- 4x 3x10 screws to hold the mcu in place
- 1x 3M Dual Lock SJ3550 tape to mount the system onto the display
Software
Check out the SimHub Wiki on how to set up and wire the WS2812B LED Matrix and the encoder.
The NodeMCU of the retraction mechanism can be controlled via ESPHome & HomeAssistant or Arduino Sketches.
