Opensource security token

Google Opensourced aspects of its Titan keys, so you can now build your own with a $10 (not including shipping) Nordic, nRF52840, Dongle. Looks interesting. I wonder what this will do for companies that build similar tokens but at the $50 range.

Using the head from a cordless drill as an endstock

The title on the video confused me. The author basically is using the head from a cordless drill to be part of the tailstock for a homemade drill based lathe.

Cool LED and water combo sign

I wish the author included a video of it working. It looks cool as the LED shines thru the sign and water runs thru the lettering.

Nice spindle drum sander build

For using with a drill instead of a drillpress. Author did a bit more work than I would have in making it, but the do look nice. And they still can be put onto the drillpress.

3D print a brake for your vise

Interesting build for a metal bending brake for your vise. Not so sure I would do this as I don’t know if I would trust it. Also you can buy one for your vise for $40.

Review of a resin printer

The author did a nice review on a cheap resin printer. The Phrozen Sonic Mini, the review sounds interesting, but I can’t find it anywhere for $200, maybe $300.

3D printed Dremel CNC

basically its the mounts and axis for a simple 3D printed CNC to use with a dremel. The write up the author does on the CNC build is pretty nice too.

Interesting video on converting a frig compressor

The author basically bypasses the relay and wires in a switch directly into the compressor to turn it on. Downside, to turn it off you have to cut power to it.
