Posted on April 14, 2023 by robertwilkie

Pretty much adding a drawing attachment to a 3018 CNC (which I think runs around $200). Not a bad idea to multi purpose the CNC.

Posted on April 13, 2023 by robertwilkie

Nice built to automate cutting a gear from a disc, you enter in the diameter of the circle, number of teeth, and it goes thru and cuts the gear for you.

Opensource Pasta cooker

Posted on April 12, 2023 by robertwilkie

OK it doesn’t cook the pasta, its a sensor/timer for passive cooking the pasta, basically instead of leaving it in boiling water, you heat up the water, put the pasta in and this device tells you when its done (before the water gets completely cold). Interesting build

The poor person’s bubble machine

Posted on April 3, 2023 by robertwilkie

I got a kick out of this one, the Author basically glues on cheap wands from dollar store bubbles and puts them on a disk that spins and blows out bubbles.
