This planetarium (a mechanical model of the planets in our solar system) consists of 6 planets (Mercury, Venus, Earth, Mars, Jupiter and Saturn) who are in orbit around the sun. Each planet has it’s own Raspberry Pi Zero W, a stepper driver (Adafruit Motor HAT) and a stepper motor (NEMA 17).
On a website any date can be entered after which the website sends out a string with the positions for each of the planets. The Raspberry Pi picks the position up via wifi, calculates the position and takes the steps necessary with the stepper motor.

Re: planetarium
Very attractive and educational. I'm sure American fans will appreciate the option of including Pluto, but would its path be circular as well?
Hallelujah!

Pluto (and Neptune and Uranus) can be included, but if you want to scale it right you need a big ceiling......Disciple wrote:Very attractive and educational. I'm sure American fans will appreciate the option of including Pluto, but would its path be circular as well?

Re: planetarium
It took a while to write and sort things out, but the first release of the documentation is written.
