Cool 3 color CNC wall plotter

Reminds me of the Maslow CNC in its build. Most of the parts are 3D printed and it has an internal gear to switch markers. I like how the author uses vasoline for “grease”. Parts here https://www.thingiverse.com/thing:4192091

Nice center punch build

But its alot of work, for something you can get pretty cheap at Harbor Freight. Me…I think I would buy it myself. Thought the homemade one does seem to work better. https://www.homemadetools.net/forum/spring-center-punch-video-90441#post200601

OK crazy boat motor build

The author uses 8 cheap DC brushed motors, and an 8 way gearbox to drive a propeller for a boat. Cool build but I don’t know how long that setup will last.

Now you have to attach staps to the person, but its an interesting build using an arduino to tell when someon is not telling the truth.

3D print a frame for Pingpong ball disffusers

Basically you use the ping pongs as an LED diffuser. Neat idea.

Turn a RPi into a Dogecoin miner

Not so sure how much you would get from this, or if you get even close to enough to cover the electric costs. Anyways could be a good way to into people into mining. https://www.instructables.com/How-to-Make-a-Raspberry-Pi-Crypto-Miner-Dogecoin/

Nice short write-up on using dowels for joints

The author does a nice job on how you can a tool called the dowelmax to use dowels as corner joints. But…I have seen several homemade tools that do the same job. Still nice article to read up on.

Using a RPi as a security camera

Interesting build. Myself, I am still fond of Wyze cameras, thought some changes have me a little concerned. https://www.makeuseof.com/create-a-multi-camera-cctv-system-with-raspberry-pi-and-motioneyeos/

3D printing forms for making custom paper shapes

Basically the author takes old paper, converts it back to pulp, and then puts it into a form he 3D printed out to shape the paper. Nice idea to make custom containers.
