OSHWA-themed Learn to Solder add-on board for the Open Hardware Summit 2018 badge designed by Andrew Sowa
Here is the parts list.
5mm color changing LED:
EDGELEC 100pcs 5mm RGB Slow Flashing LED Diodes Multicolor (White Lens / Colors Changed Automatically) Diffused Round Top +100pcs Resistors (For DC 6-13V) / Bulb Light Emitting Diode
E-Projects 500EP5141K00 1k Ohm Resistors, 1/4 W, 5% (Pack of 500)
E-Projects 500EP514470R 470 Ohm Resistors, 1/4 W, 5% (Pack of 500)
NOTE: Resistor value should be chosen based on personal preference for brightness. I found the LED to be too bright with 470 Ohm while inside my apartment with indoor lighting. I preferred to make the LED dimmer with 1K Ohm.
