SMH
It's only november and they've already put up christmas trees...

"Oh this should be around 20 mm, the dimension is not critical"

The result: a few 100 nm off.

I bet the next time I actually try to get something to this accuracy it will be way off :|

God fucking damn it I hate malls.
They're all kinds of sensory overload and none of them are fun.

Well that's *basically* half a LINAC, right? 😋

Today I cleaned and de-rusted a pair of machinists vices I found on the scrapyard a while ago. By the looks of it they're some apprentice pieces, and they are beautiful!
But they do have some issues as well, the one on the bottom has significant jaw lift, while the one with the rotatable jaw has its pin at a slight angle so the jaw can't actually be screwed down when rotated around. Maybe re-drilling and -reaming that hole for a bigger, straight pin will solve that.

Fyoooshn!

Ah yeah, that hits the spot

aaaAAAAA
Who spec's current like this???
10⁻³ fC/ns???

I found a small cyanotype set at a local store and was afraid today wouldn't be sunny enough, but it worked so well 😍

And a few more!
I'm not entirely happy with the bubble chamber print, bug from what I understand it will get more contrast in the next few days due to further oxidation of the blue pigment.
I didn't take a pic of it, but the unexposed paper is a blueish green

I have acquired a geiger counter with a satisfactory number of buttons, dials and switches!

Now I only need to find some 1.5, 15 and 75 V batteries for it, or fitting switching regulators. The count indicators are basically discretely built decatrons!
Schematic is in the manual:

@North Yep,!
I actually confirmed that, in the center of each walkway the radiation is less than at the surface.

The
whole
fucking
station

is uranium glazed???
That must be tens of kg of uranium!

Hot damn I almost didn't want to leave

Edit:
Fuck sake there are so many armchair experts here.
NO, this is NOT dangerous!
Radiation is all around you and so far you have done just fine surviving that.
It's a nice color and an interesting historical fact, and that's all there's to it.

Don't talk to me or my son or my son or my sons son ever again

Sometimes you just get lucky on ebay!

I fucking LOVE these old school (literally) posters and been looking for this one for a while now!
Soooo happy right now 😍

A friend was visiting a glass blower in Czechia and I ended up with a care package 😍

Cubes, a shotglass and scrap for my own experiments, I'm so happy!

Also, fuck you, if you have the right of way just fucking take it.
Don't wait until I have come to a full stop to then be "nice" and wave me through.
Just fucking drive and follow the traffic rules!

*Me, venting over being almost run over three times while biking to work this week*

Colleague:
Aha, yes, but you see, I once also saw someone on their bike not showing their best behaviour!

Lychee Pear
Vanilla raspberry

Man that's a great way to start the day

A nice evening of trying to get the best out of our SEM!
