About the Saxion-Sky-Projector PCB

Saxion-Sky-Projector is an open source AVR/Arduino PCB design by Emanuel-de-Jong, published on GitHub. It is a board, with 42 components from 12 distinct parts.

Its main chip is the Arduino UNO R4 Wifi, from the AVR/Arduino family. Other key parts include the PCA9685. By type, the board carries 12 transistors, 9 resistors, 8 capacitors, 4 modules, 3 diodes and 2 fuses.

From the project

A hand crafted light refraction ceiling projector.

A DIY controllable and customizable 3-in-1 sky projector. The code is nothing special, but the technical components, prototyping and planning were interesting. I made a schematic and a 3d model and used components like MOSFETs and PWM Drivers.

With the high power LEDS, I also had to take heat into account in multiple places. Aluminium bases, a fan and even a thick heatsink were needed.

Saxion-Sky-Projector: common questions

What microcontroller does the Saxion-Sky-Projector use?

The Saxion-Sky-Projector is built around the Arduino UNO R4 Wifi, from the AVR/Arduino family.

How many components are on the Saxion-Sky-Projector?

42 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Saxion-Sky-Projector design files?

From the Emanuel-de-Jong/Saxion-Sky-Projector repository on GitHub, which has the schematic and a netlist; the links under Design files point to each one.

Can I use the Saxion-Sky-Projector design in my own project?

The repository has no license, so all rights stay with Emanuel-de-Jong. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Saxion-Sky-Projector without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
