Hi, the project I’m working on right now is Casper. Casper is a modified 6’’ dobsonian telescope that can automatically point itself at a planet or other celestial body.

Besides a lot of research what I have done so far is make the schematic for the control board PCB. The control board includes a STM32 microcontroller, stepper motor drivers, Raspberry Pi Zero, and much more. I made it all in KiCad so the time does not log but I spent roughly 7-8 hours on making it.

How I went about making it this is I started out selecting the integrated circuits (ICs) I would use for each part of the board. I need a microcontroller, stepper motor drivers, buck converter, and a LDO. Once I knew those parts I looked at the datasheet to find the standard application circuit and followed that pretty closely, with some modifications.

Next steps are to start laying out the components for the actual board and make traces to connect them all.
