full source and story:


Why I started with this project?

Original i had a good deal on 600 Nichia SMD LEDs -
this led type is normally used in big outdoor screens…
very bright for the size and very good color and binning…

Which PCB Design Tool I use and why?

  • Kicad
  • its the only option i like to use :wink:

What’s my greatest fail with the project?

  • killed ~5 boards → they are missing a polarity protection!

What’s my greatest win in the project?

  • find new communities with reflow ovens :wink:
  • make friends in this communities :wink:
  • learning in all areas :wink:

hm… currently iam only allowed to do one image per post…
