@f4grx @sad_electronics which are well spend money. Would recommend.
Absolute 0-brainer if you work with this stuff professionally. And decent for DIY stuff.

It works!
Now I need to mount two of those into the case. Which still needs to be build.

This is also a #NameThatWare what is the source of those pulses?

@azonenberg manually manufacturing is probably faster than all the research you put into it. Even if you need 50 pieces.
Slotted screw, solder a washer into the slot.
Takes a few seconds per piece.

@azonenberg Those are "DIN 580", which apparently are also available in M3. But not part
The opening of the ring-hole is 11mm for those M3 types. That might be to big for your application.

If tinkering is allowed, solder/braze/weld a washer to a screw. Then you have full control over sizes.

@cd0 can you share the .svg so others can try?

@jomo on scihub? I accessed it at work, where it was automatically licenced with the university contract.

It is finally confirmed. The esoterics were right! Living things do have an aura!

It is actually biological ultraweak photon emission (UPE). Which is extremely low-intensity emission (10−103 photons cm−2 s−1) in the spectral range of 200−1000 nm.

The effect was known, but this paper shows methods to actually take pictures using electron-multiplying charge-coupled devices.

Here is the paper: pubs.acs.org/doi/10.1021/acs.j

@int21h Not wrong, but one important part is missing.

Here is another #NameThatWare challenge.
I opened this device to learn how its working and how to connect to it.

As always, hide jour guesses and deductions behind a CW.

@la @cccac perhaps you should invest into a new dial indicator.

Since the measuring instruments cabinet @cccac got too messy (my fault) I've gone ahed and made some foam inserts for them. One done, two to go.

A piece of foam with pockets of several measuring tools in it. Among them: Dial Calipers, a small machinists square, a micrometer, a small straight edge, a dti (mahr puppitast) and several (7) indicators of different resolution and ranges.
