Nice PC fan build

I like this fan build. Only interesting bit was the author build his own PWM controller. Which I think you can pick up pre-made for a few dollars more than the parts. https://www.instructables.com/id/DIY-Cordless-Table-Fan-From-Scrap/

Nice looking mini lathe build

Rather sharp looking lathe build. Not so sure I would make one from plexi-glass, but it does look nice. The author even designed and make his own motor controller. More work than I would have done (just would have gotten … Continue reading

Bump stops for your CNC

The free plans are fore an X-Carve, but could be adapted to any CNC. My 2 cents, I was looking at this build and it would be pretty easy to build by hand as well with scrap wood.

Nice write up on making knobs

Only part that adds a bit complexity to this is cutting the t-nut to allow for screws to be placed in to hold them in. Me…I superglue them in. https://www.instructables.com/id/Stupid-Easy-Project-Knobs/

Turn a drill bit into a Scribe

Convert a Scion xB into a camper

I want one of these sorting machines

Its fun to watch the video. Basically a light from the bottom lights up the parts for a camera to take a pic of and figure out what is what in shapes, then it picks them up and puts each … Continue reading

Turn and old metal saw into a plastic cutter

I got a kick out of this one. The one thing that worries me is the one end of the line for voltage is pretty much exposed and near the handle where your hand would go. And get zapped. Besides … Continue reading
