First in a series by Jeremy Fielding on building your own CNC machine. He even adds a 4th axis to it.

Anyone know the differences between Librem 5 and Necunos?

I decided to replace the old under-the-cabinet fluorescent lamp (hasn't worked in years) with an adhesive-backed LED strip (warm white from Ebay - $7.50 for 5 meters). I got a 12V switching power supply wall wart ($8.00 from Ebay), removed it from the case, and stuck it a wood box (held together with 5-minute epoxy). The box is stuck to the cabinet wood with Weldwood contact cement. The little brackets that help the LED strip stay up are made from 1/16" UHMW.

I'd like to take a moment to praise d-sub connectors (DB-25 etc). They're awesome. I'm surprised by the current they can handle every time I look it up. You can't connect them backwards and they're easy to solder to.

All of the motors on the Cocktailor are powered through a DB-25. A lot of my model planes have DB-9s in them to connect wings etc.

For anyone who wants to contribute to individual FreeCAD contributors, there's now a Librapay team page set up.

liberapay.com/FreeCAD

It's my understanding that when you donate to the team, it gets evenly distributed among everyone in the team. You can still donate separately, and all three of the devs on there currently are also on Patreon.

I'm working on a new mount for my lights stand. I decided to use M5 hardware for everything.

The whole square thing around 1/4-20 bolt was not a great idea, but version 2 is on the way.
