LED Dimmer for Fairy Lights

Gruffalo Fairy Light Dimmer

A simple LED light dimmer. My kids love fairy lights, but the ones we have are too bright to use them as sleep lights so I thought about churning up a quick PWM dimmer for them.

It's a simple project with simple goals:

• Do some electronics. I won't get the Noble prize on electronics for this one.
  • Subgoal: doing something in the incredibly sexy After Dark finish from OSH Park.
• Play with the Silicon Labs toolchain. I don't have any FW on my Github.
• Work with encoders. They are tactile and they are nice!
• Think a bit on user interfaces that children can use.
• See how far I can get without getting sued for copyright infringement.

The design acts as a motherboard for another of my projects, a breakout board for the BGM220P BLE Module.

This is more or less how it looks like. The renders are done with pcb2blender, and it doesn't handle transparent soldermasks yet, so it's not showing the underlying copper base.

Tools I'm Using / Stuff I'm Stealing.

Made with:

• KiCad, obs.
• Inkscape, for the art manipulation.
• Fusion360, for 3D model generation, as a source for my Fab layers and for the enclosure.
• Blender + pcb2blender, to generate my renders.
• I'm using KiBot as the main tool in my CI/CD pipeline.

Things I definitely didn't do:

• The art, taken from certain children's book authors.
