features

  • Since it was my first time I wanted to keep it simple
  • the main thing is a 555 timer that flashes 2 LEDs
  • There is also an LED + photoresistor so there's more light when it's...bright (I thought it went the other way around while I was making this oops)
  • and a push button at the beginning of the circuit.
  • Also has silkscreen art by me on Krita :D and a bit of FR4 art. didn't have time to figure out copper loll

I would have liked to add something to do with the motor (a lil buzz fidget or something) but that didn't happen rip. also the transistors are cool I just couldn't figure out what to do with them (except fix my photoresistor LED).

Questions

How big is the Pcbrushy PCB?

It measures 84.6 × 87.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pcbrushy use?

18 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Pcbrushy KiCad files?

From the Herbeon/pcbrushy repository on GitHub, at the commit this page was made from: the board is pcbrushy/pcbrushy.kicad_pcb and its schematic pcbrushy/pcbrushy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pcbrushy design in my own project?

Its repository states no licence, so its author keeps all rights: ask Herbeon before reusing the design.
