Make an interactive stand for your Google Home

Make some light up ice skates

Cool IC Tester build

Posted on February 26, 2018 by robertwilkie

Seems to have a pretty extensive test set too.  Good way to verify a chip is working, or that its what you think it is.  The board you can order (author opensourced it) and its nothing but solder points for … Continue reading →
