Made this fun little desk thingy, five different modes, live flight tracking radar display, spinning globe, ai robot 'assistant', and then a clock in the style of an altimeter.

Uses both a pi and then a waveshare 2.8" esp32 display all in a 3d printed case.

Built it as a gift for my son who is in the air force, so it's supposed to look like a bit of old military gear.

I have one of these helium tanks sitting around, and would like to do something with it. Any ideas? It can be something useful or something decorative. I'm also into car track days, woodworking, and music if that inspires anything.

I am installing s panel for camping gear and fez hats. I have a space of 90 mm or 3.5” that i need to support.

I have tons of M8 bolts that I am thinking of using to use standoffs for the supports.

I am looking at Amazon, Ali and google, but not finding anything, any suggestions. Other options.

This is just the jewelry I made last weekend. If there is interest I'd be happy to post more. Let me know your thoughts.

I’m an ok carpenter and plumber, but I know very little about electrical. I could use some help/guidance on this lighting situation.

I’m making a parade float where I’m trying to string together some little lights. It’s going to be a bunch of these lamps (or similar).

How do I daisy chain 8-10 of these together so they all work of the same switch?

Do I just cut the chords and connect all same-colored wires?

Any help is appreciated! Thank you!

Spent a lot of time designing this — 60cm long, fully 3D printed chassis, dual brushless motors with custom gear reduction, held together with screws and brass threaded inserts. No glue anywhere in the build. This is the moment in Episode 1 where the tracks finally moved on their own. The motors had been overheating for weeks, then torque was insufficient through two gearbox iterations, then the suspension nearly couldn't hold the 12kg weight. Three redesigns later, here we are. Full build breakdown on YouTube if anyone wants the engineering details (linked in comments because not sure if main post allows). Happy to answer questions about printing settings, motor specs, or the gear ratios.

Hand forged cuff in twisted Elite Coppermai. Perfect twist, no delaminations, and an awesome pattern. What do you think?

YouTube video is live for interested folks and it has tons of real-world tests and engineering info on how I achieved this insane output

I teach STEM and robotics and teach the concept of mechanical advantage with gears. Sometimes I want to make custom gears depending on the project and it's normally pretty tedious so I built (vibe coded) a web app that exports svgs for the gears and base plate.

While I lasercut them, you could easily convert svgs to be 3d printed too.

Hey all, I finally finished an etch a sketch project that I've been working on for almost a year now. It started off as a digital etch a sketch (using eink) and next thing I knew, I had built an etch a sketch camera. This footage isn't from the camera itself but rather, I imported the Simpsons couch gag into it and had it do its thing. I also had it make a colored version of the video by looking at the what the underlying pixel color is, and make a gradient line from point A to point B. Hope you like it!

I just wanted to share my Laser Engraver enclosure. I’m really proud of it but nobody else in the house gets it 🤣
Made from 1/2 and 1/4 inch melamine, 3D printed parts and acrylic. It has a 6in exhaust fan that moves about 300CFM and 3D printed quick connects so it’s easy to setup and put away.

Titanium miniature hydraulic cylinder.

Something a little different. A custom cube in different progressions of basket weave damascus. Brazed together with sterling silver and phosphorus copper. The gaps are filled in with black epoxy.
