Geared tracker for astrophotography

thingiverse

It appears you've shared a detailed guide on creating an astrophotography tracking system. I'll help you break down the content into a more readable format. **Components** You've listed several components required for the project: 1. Arduino board 2. Tracker head 3. Power supply (lithium-ion battery pack) 4. Charging socket and cable 5. Switches (mini on-off rocker switch, standard-sized DPDT slide switch, miniature push button switch) 6. Battery box **Tracker Assembly** The assembly process involves: 1. Mounting the tracker head on a tripod 2. Attaching the camera's ball mount to the tracker head 3. Connecting the control box to the tracker head **Controller and Tracker Functionality** The controller allows you to select between siderial, solar, and lunar time modes. Each mode is indicated by a flashing LED. * Siderial time: Green LED flashes at 1 Hz * Solar time: Yellow LED flashes at 10 Hz * Lunar time: Blue LED flashes at 0.1 Hz **Aiming the Tracker** You've added a picattiny mount to the tracker head for aiming purposes. At night, you use a red dot sight to find Polaris (the North Star). In the daytime, you can use a phone mount and Google's Sky Map app to find Polaris. **Testing the Tracker** You've tested the tracker using a simple aluminium bracket with a white card at one end and a pinhole at the other. The sun's image was still central after 2 hours, indicating that the system works accurately for astrophotography. **Updates and Additions** You've made several updates to the project: 1. Added SCAD and STL files for an alternative lid (siderial time only) 2. Added a single LED trim for use with the siderial time lid 3. Updated the control box design, including: * Improved lid fit and assembly * Changed charging socket to avoid accidental power supply connection * Added OpenSCAD library for generating switch hole positions
