Bought a plate of slate at the euroshop and got a piece of pyrite with it!

@whitequark They're everywhere here, used to be 1€ for everything, now it's 1 to 5€ depending on the item. Most of what they sell are household items, snacks and toys

In the pyrite community we call gold "Fools Pyrite"

Don't you love it when you watch a video of someone telling their experience with autism and it feels like a biography of your own life...

wellp.

So here's a fun experiment:
Nuclear Track Detectors from the hardware store!
I bought some protective sheets for welding masks which are made from a plastic called CR-39, exposed them to a radium watch face (two sheets, one on the front, one on the back in case there is some coating) and now, if I etch them, they should show tracks / tunnels where alphas hit the plastic!

Now I only need a day off where I can watch a vat of 6M NaOH boil for 6-8 hours...

And in they are!

Another attempt and an ABSOLUTE success!
I am so happy with this, it's really simple and absolutely stunning!

Unfortunately it doesn't image all that well, but the holes are definitely visible!
I think it needs more etching time, they aren't as deep as I would have expected.
Still, amazing to see and to think that every single dot on there is produced by one single helium nucleus!
You're basically counting atoms here ;-)

Ceramics class! I made a trio of mugs, two of which are marbled, and I started on one of these donut shaped jugs that I was reading about on Wikipedia. That donut is hollow

Ohh fun, ATLAS just caught something cosmic!
At the moment there is no beam in the LHC, and it's a straight line through the detector but not the beam collision point in its center.
I wonder how they select events to display here, if this just happened to trigger all the right... well, triggers.

Flea market time!

Sooooo
I made a small "investment"

A friend who has supplied me with great scintillators in the past is retiring, so I decided to get a few more before he could not sell them anymore.
This time he really outdid himself and made a perfect NaI / PMT assembly, which will replace the detector in my lead castle. The CsI are perfect for smaller / portable detectors, the rest is for my collection ;-)

It's interesting to see the difference between batches, look at the colors under UV!

@RichiH A good bit, but definitely less than "market value" ;-)
The whole set cost me around half of what a new, off the shelf NaI like that alone would be!

Has YouTube added a way to pay for videos to appear on the front page?
Mine is currently full of 1-20 view 10-30 second videos of random companies displaying their products.
Glass cutting, tuna processing, PET bottle cutters for recycling, you name it.
What the hell.

The street lights failed for a few hours and it was an entirely new world!
Kinda want it to go dark again

I have poor self control

I have tried and I have failed.
This definitely was not the right way to go about winding a 45° coil.
I'll redo and print the holders this time instead of lasercutting from acrylic, and I'll have the tube clip in instead of wind through, that was such a pain!

gigabecquerel,
@gigabecquerel@chaos.social avatar

One 40 hour print later and they came out PERFECT!
The 6 mm copper tube clips in really well, can't wait to form the primary around them!

10ish primary windings, and one (probably optimistic) strike rail!
Still some cleaning up to do tho.
Next step will be the spark gap!

Wellp, this is going to be fun to solder

gigabecquerel,

Half way there!
I like how it turned out, looks properly chunky, at least for this size tesla coil

Aaaand done!

And the stack is done!
Voltage testing TBD, but it looks promising.

Worked like this for maybe half a second, then something arced over in the MMC, charred and gave the high voltage a nice and easy path to get through.

But damn, I'm definitely on the right path!
