This year at the Seattle and Portland Mini Maker Faires I did a presentation on getting started with designing your own PCB using KiCAD. In this presentation as an example I created a pumpkin shaped PCB with a candle like flickering LED.
Here are the KiCAD schematic and PCB layout files to use as the starting point for your own project:

The Pumpkin PCB is now also available as a kit:

So where do you get the flickering LED? I don’t see any part numbers or bill of materials.
The flickering LED is a Betlux Electronics p/n: BL-L101UYW-B-S3. You can purchase individual ones from Evil Mad Science http://evilmadscience.com/productsmenu/partsmenu/408
Just wanted to thank Eric for these great (and fun!) kits. I received three yesterday and built one late last night (yeah, I was excited). They work perfectly!
Will be building the other two with my boys soon 🙂
Thanks Eric!
The boys put their kits together and loved it! Especially little Tucker. I can’t believe that at 8 he could do it, but he did — all by himself.
Here are some pictures of him at work.
