My latest free tool, ScanRuler.com, can automatically reverse-engineer your 3D Scans! Just tell your AI agent to connect to the ScanRuler MCP give it an stl and tell it to reverse engineer it. A detailed video and a custom skill will be released in the next few days!

Working on a new tool that automatically reverse-engineers 3D scans into really good CAD geometry. This example took a good hour, but man, does it look good and clean!

My first Claude Code project! github.com/benkrasnow/OpenPl… Single-page web app with COM port IO. I really enjoyed using Claude, and this app is something that I will definitely use in the near future.
I had a single-stage oxygen regulator fail "open", sending tank pressure to the output. The seal looked like brown candle wax (crumbles on right side of photo). I didn't know they could fail this way just from age and normal use.
I recently learned the USGS has free aerial LiDAR data for many areas. Draw a box, then click the green button on the right side and select Eptium viewer. apps.nationalmap.gov/lidar-e…
Also, I have quite a few videos that are soon to be released, but the perfectionist in me always causes me to wait, trying to add things, or improve things, thinking I can always make the video a little more interesting.
I'm looking forward to being a featured creator again at Open Sauce 2026. It's a really fun event that celebrates creativity and technical ability. July 17-19 at the San Mateo Event Center. Check it out! opensauce.com/

Hyundai now requires you ask permission to change your brake pads. A $2,000 adapter. A $60 weekly subscription. This makes repairs at the shop even more expensive. Oh, but you replace your brakes yourself? Well, they also want a business EIN. No DIYers allows.
You bought the car, but Hyundai still owns the brakes.

Hey all! Its unfortunately time to find a new home for my SEM. if you are interested take a look at this doc. TLDR: asking $2,250 OBO, pick up in Santa Clara CA. Other than that its best offer / whoever makes it easiest for me to move it on

This is a room with >2000 CNC mills near Shenzhen that I've been inside. The mills are arranged in cells with multiple tended by a robot on tracks, so there are very few people working on the floor.
There are dozens like this in China.
What's the biggest similar facility in the US?

update: We are hiring a software engineer, if you are interested in evolving from replying into becoming a “stove person”.
More info in the next tweet.
