Me when computer

Raspberry Pis really come with their own flavor of computer sickness, don't they.
I pulled one from the scrap pile at work and since then I've been thinking about what to do with it!
Many fun ideas, but the second I think about them in any way I realize that this can be done better and cheaper with either a microcontroller or a cheap (or often times free!) old computer.

Wellp, my thesis is due, but I doubt I'll be able to finish it in time with news like these

Finally!
After watching them weld at this construction site for months I happened to go by just as they got ready to inspect the welds!
The source is a lot smaller than I expected it to be, it's a B-Type container made from depleted uranium. In it is a TBq or so of Ir-192 or Se-75, depending on the weld thickness and material.

Random question: Is anyone here working on / with a HVEC Van De Graaff Accelerator? Ideally an "original" belt driven one. I'm looking for details of the charging and terminal brushes, specifically their geometries. There are many different variants with the brushes directly lying on the pulleys, sometimes they're a bit down-stream, sometimes they are down-stream and have an extra opposing electrode... I just would like to know how it was actually done, and not just simple schematic drawings.

There are a lot of warnings for CF / GF loaded 3D printing filaments, so I wanted to see what's going on.
I printed a piece of Prusament PP-CF and it felt like a Kiwi fruit! The @FabLabMuc@muenchen.social SEM Pics explain why: There are tons of exposed Carbon Fibers on the surface! It's pretty rough overall, doesn't look like any other 3D print I've seen before.
I'm surprised how many of these fibers just stick out, like they're not embedded in the plastic at all!
The last pic is of a broken edge.
