Some new stuff just arrived

So, I've got some fresh stuff from the workshop. Still in as-received state, but this is a big step for now. Just see how blue-prints turn into reality:

PCB for the ammeter arrived! Not yet populated, as I'm still waiting for the ICs (should be here next week). I hope that everything will fit, as some drills are smaller than expected

Sample holder is also ready. It turned out very nice. Maybe not exactly as in the render, but the crucial parts are ok. Also it is blackened, to limit light scattering from it.

Also the vacuum chamber parts are done, but I still have to put it together - expect some pictures soon.
