Looks cool! - does it run off batteries or something like that?
Getting a lot of scopes to run from DC is not anything special these days if you're happy to do away with a Line trigger. Many of the later Teks ran a prereg stage into their SMPS where some 45V is all that's needed for them to run on DC whereas many DSO's will run on ~15V if you bypass their SMPS and feed them with DC.
Just gotta do your homework.

Any reason you couldn't run a scope off a sine wave inverter and a 12V car battery?

for the two 34401A

Any reason you couldn't run a scope off a sine wave inverter and a 12V car battery?Not excepting for load constraints and lack of mains earth safety risk.

And the fact that you are then converting DC to AC so that the SMPS can convert it back to DC at almost the same voltage (and of course all the accumulated losses along the way).

If you're only doing this infrequently, efficiency is not a big concern.

True, but it still doesn't seem sensible. It's like using a sinewave inverter in a car, only to then plug in a USB charger to charge your phone. Why not just use a DC/DC converter to increase the voltage directly?

Added a small LED bar at the top of the bench to improve visibility.
And this little S1-107 scope is quite useful, sometimes even more useful than the other, much better scopes.
5MHz single channel is not much. However this thing can run on 27V DC, allowing measurements of floating potentials (well, mains are internally isolated too, but I wouldn't want to stress the isolation) like for example VFD's, welders etc.
This thing also comes with 20V/div setting which means it can display a full 1200Vpp signal on the screen using ordinary 10X probe. My two other scopes (schlumberger 5228 and Tek TBS1042) can only do 400Vpp on 10X.
Quite useful for that last 150-200V extra when measuring flyback primary overshoot.

An old Soviet oscilloscope pleases the eye, but it is still dangerous to fly it at high speeds. Look at my simple isolated probe for low frequencies. You can buy components very cheap on Aliexpress and recalculate the resistor to 1500V, for example.

And the newest addition to my workbench.
A 100W transformer soldering iron.
[...]
I started to play with electronics on such transformer soldering irons - I have two such soldering irons, one ZDZ 75 / 45W Łódź soldering iron
and the second ZDZ 120W Lodz, despite many years of service, work perfectly. They are great for soldering cables, I use them when I need to fix something in cars, sometimes with electronics
I started with such soldering gun too, when I was 8 years old, now I'm 23 and I decided to go back to it.

Cool idea with the isolated power strip, definitely easier than digging out the isolating transformer every time - I might copy that!
I recently moved my electronics workshop into a separate room, as in the old workshop it was to messy (dust) and cold in the winter.
Nothing really special to see, just basic equipment, but i have some space on the shelves to fill in the future
I need to install the power outlets on the right bench, same as on the left one, hope to find some spare time soon...
