Erinnerung: Heute Abend im #cccac ist der #FreeCAD Workshop.
Präsentiert von @la und mir.

Am kommenden Mittwoch, den 01.07.2026 findet bei uns im Clubraum ein #FreeCAD Workshop statt.

Zielgruppe sind Menschen, die noch keine Erfahrung mit FreeCAD haben. Wir zeigen euch, wie man 3D-Objekte modelliert, um diese dann z.B. zu drucken oder zu fräsen.

Following recent news, we have cancelled Mullvad's sponsorship of EMF 2026.

If you'd like to contribute to make up for the lost income, you can still sponsor EMF through our ticket shop:

We might get a geometric constraints solver in #KiCad

I don't know much about it. But there is an open MR https://gitlab.com/kicad/code/kicad/-/merge_requests/2663

From the commit message:
> It lets users attach geometric and parametric constraints to PCB and
footprint graphics so dependent geometry is re-derived on edit, instead
of converting every relative datasheet measurement to an absolute number
by hand.

The solver is FreeCAD's planegcs, vendored under thirdparty with pcbnew
owning the adapter

And that’s a wrap for the LHC sort of! Coming “soon” (2030ish), the HL-LHC.

The IKEA Spain #Blahaj manual has vectors.

Idea: Drag Soldering Workshop

Station 1: get dolled up
Station 2: solder some QFP chips

This weeks #FreeCADFriday job is a little meta: making a handout for a upcoming #FreeCAD workshop in out hackerspace.
This is heavily inspired from the #KiCad workshops I have been doing in the past, copying the basic concept.

Die #Saarland Uni entzieht 13 Persönlichkeiten wegen deren NS-Vergangenheit an der #Saar die Ehrenwürden. "Auf Grundlage heutiger Maßstäbe erscheinen die von dem Beschluss betroffenen Personen nach Überzeugung des Senats nicht länger als ehrungswürdig."

It is finally done! The mill @FabLabMuc now has a DRO
Thanks again to @cccpresser for sending us the DRO!

I’m also really happy with the wall mount, it was may first bigger metal project with multiple parts. And my plan with welding the structure and then milling the important faces to spec went really well

Compiling #KiCad on my machine is just no fun.

And this was an incremental build - but with at least a hundred new commits.

#makerworld is such a scam. Why does it need a login to download 3D models?

I wanted to get some files for a #emfcamp2026 workshop, but no, its just not possible without making an account. The stuff on bugmenot also does not work because makerworld wants 2FA via email.

Ofc. I could waste my time by making a new account with 10minutemail or so. But I don't want to. I just want to download the fucking .stl and be happy.

Can we please go back to thingiverse? Or move forward with manyfold?

As the saying goes: Age is just a number. And even though we don’t know the age of many #StarTrek characters, it can be interesting to compare them. So let’s see if you can guess who is how old for today’s #TrekTriviaTuesday question.

As always no googling and no spoiling the answer for others. Please boost after voting! :BoostOK:

Vote will run for 24h, then I will reply with the correct answer.

Which of these characters were born in the same year?

social.saarland wird geschlossen. Wenn sich jetzt niemand findet:

Nach Jahren der erfolglosen Suche nach einem tragfähigen Betriebsmodell mit engagierter und verantwortungsbereiter Führung geben wir auf.

Es gibt quasi nix zu tun, es kostet (knapp) unter 100€ pro Monat, lediglich droht latent eine rechtliche Haftung die idealerweise auf den Schultern einer Organisation statt einer einzelnen Person ruhen sollte; Dennoch fand sich niemand.

Keiner machts -> Ende Gelände.

When routing tracks connecting pads of different function, like power input and enable, always place the tracks in such a way that you at least have a chance of cutting the track to fix or debug any issues you didn't anticipate. Especially do not connect logic inputs directly to power planes. Future you will thank you.

Ich hab 2 Tickets fürs #Rockharz Festival in 2 Wochen übrig. Ich habe original 200€ pro Ticket bezahlt, und würde die gerne für den gleichen Preis weitergeben aber alles ist besser als wenn die verfallen. Macht einfach gerne einen Vorschlag

Is there a nicer word for 'dogfooding'?

Wikipedia mentions "drinking our own champagne", but that does not have a nice ring to it.

i’ve had a little experiment over the years of bookbinding using bare pcbs as book boards and it works well but i just need to keep practicing my stitches. I did some case binding years ago, but need to explore adhesives for that. Recently I’ve some coptic style binding thats a perfect use case and no adhesives but my stitching is sloppy. pictures below are a couple notebooks i made using ewaste destined bare pcbs from my old job as book boards

For #FreeCADFriday we have this simple T-profile used to mount some bins below a shelf.

And because 3D-Printing is boring, I convinced @derwellensittich to mill them. The only 'suitable' material we found in the hackerspace is a thermoplast (PVT) that makes a nice goo when not properly cooled.

With adaptive toolpath it gets better as its easier to evacuate chips and thus the heat. But on deep cuts the shaft of the endmill rubs on the material making just to much heat.
