Using a small 3D printer to build a big one

Posted on June 25, 2015 by robertwilkie

Make a Joule Thieft without a Ferrite

Posted on June 25, 2015 by robertwilkie

Posted on June 23, 2015 by robertwilkie

Clever idea, the author built a mini dust collector (typically big ones you use to get sawdust before it goes into your shopvac) to find small parts that he dropped.  I like the bug screen addition to the build and … Continue reading →
