I purchased mine from to get some quickly, but search ebay for massive quantities and cheap prices, but expect the usual wait on shipping from China. They are sold in bulk on fleabay dirt cheap.

I'm using 31AWG magnet wire in red and green so I can identify polarity. This wire has an enamel insulation on it. I just scrape off the enamel finish on the ends with an Xacto knife to prepare for soldering.

The SMD LEDs that I'm using are size 1206. I'm...Continue Reading
