- 3D printer + filament (approx 300g per winder)
- Soldering iron & the skills to use it
- Basic tools
- Screwdriver
- Hack saw or a rotary tool with a cut-off wheel (to cut the 4mm metal rod to size)
- Sandpaper or files. This will depend on how dialed-in your 3D printer is.
- Epoxy glue
- Again, whether you need this or not will depend on how dialed-in your 3D printer is.
- How to use a multimeter (we'll only check for continuity)
- Some spare small-gauge wire (ex. 22 AWG)
- Rudimentary knowledge of electronics
The following parts list will allow you to build:
- 1x powered winder (required)
- 2x un-powered winders (optional)
This means that you'll be able to construct a 3-watch winder. Remember that the system is modular, so if you decide to only build a single powered winder, that's ok.
- $40.00 (February 2023)
Caution
If you're planning a Winderoo build, do not purchase a Raspberry Pi Pico. Purchase an ESP32 instead to save some money and avoid future headaches. You can find a link to purchase an ESP32 in Winderoo's Bill of Materials.
