100 Second Build - LED Flasher

All in a day - and three iterations to get it right

JF Brandon (BF)

As part of a new series showing off how fast we can print a board, here's a short video of how we built a simple 555 timer LED flasher in an afternoon. The first iteration took about two hours, from start to finish. We had to do a few small turns to make sure the wiring was correct (we were missing the right cap and dropped the transistor in the original design). Each turn was less than 20 minutes, and the pasting and assembly was relatively quick.

If you'd like to get the original files just drop a line by email and we'll send them over! They're a great starting point for anyone with an SV2, or to teach students on the go.
