Are you sure you understand the circuit?
What is wrong with it according to you?
As to bad design, astronauts now stuck on the ISS because the Boeing return module is defective.
Billions they did spend of tax money
US becoming more and more a lost empire...
China just did a sample return from the backside of the moon.

Aside from being ugly, at least three things.

That's fine, since the US never was an empire. But we did mostly
conquer the world by being what other people want to be.
Use Street View all over the world. Most places look like a suburb of >Houston.

Human beings have curiosity
that is how we evolve.
The sample will teach us about how our universe (forming of the Moon specfically) happened.
And if we can have a permanent base there, say as an in-between stop for further exploration of space.
Later, when US astronuts land on Mars (if ever) they will find Chinese restaurants there
and they better bring some Chinese currency so they can pay forlanding rights and food.

Am I the only person here who designs electronics? Sigh, OK.
The resistive voltage divider R2 R3 wastes voltage and power.
The SCR high-side switch is crazy for several reasons.
The optocoupler into the second dc/dc converter makes no sense and is >probably unreliable.
Why do some people use optocouplers where both the input and output
are grounded? It becomes a low-beta NPN transisor.
Why switch only the second dc/dc converter?

We already have lots of moon dirt. It's not very interesting. The
Chinese thing is a political stunt. An expensive one.
Why would dirt from the farside of he moon be any different from the
rest of the moon dirt?
And if we can have a permanent base there, say as an in-between stop for further exploration of space.
Space is mostly vacuum. Why do we need to kill humans to "explore"
vacuum?

A recent study suggests that people who go to Mars will have kidney
damage.

1000 years ago 80% of the population was farmers who barely grew
enough to survive. Clothes were so valuable that people were killed
for theirs. Most people were illiterate and lived in the dark when the
sun went down.
Progress has made us so efficient that probably 80% of the
developed-world population now has zero net productivity.

Well, given that 100% of what gets counted as productivity is devoted to >things that quickly pass away, it’s hard to get too worked up about that.
Materialism (of either the philosophical or the vernacular sort) ends in >futility.(*)

Those farmers might have been starving, but they had resources. For
example, they could grow a large family and sell off the kids if they
have a bad harvest. They could organize a mob and pillage the
neighbors crops. Every culture has a festival to mark the beginning
of the harvest season, which oddly coincides with the beginning of the >pillaging season.
Clothes were so valuable that people were killed
for theirs.
That's a rather high price to pay for wearing the latest fashions. >Unfortunately, little has changed over the last 1000 years:
"BEWARE AND BE SAFE !!! SNEAKERS GETTING ROBBED / STOLEN" ><https://www.youtube.com/watch?v=4LHrCLiMKZQ>
Most people were illiterate
Today, people are more literate but continue to do stupid things.
Literacy is not a good substitute for intelligence or a cure for
stupidity.
and lived in the dark when the sun went down.
That would be the dark ages.
They didn't last long to do much real
damage. Also, we still have regular planned power outage holidays to
remind us of those days. Here's a map of California showing past PSPS >(Public Safety Power Shutoff) events.
Progress has made us so efficient that probably 80% of the
developed-world population now has zero net productivity.
In FY 2023 the IRS processed 162 million individual tax returns.
That's out of a total population of 333 million. Subtract 74.4
million children age 0 to 17, most of whom are not required to file a
return:
162 / (333 - 74.4) = 63% of US adult population is productive
or
100 - 63 = 37% are non-productive.

That's hilarious. A tumbling dowel pin at 200 feet/sec. That might not
even break skin.
Imagine that in a battle with even a .22 rifle. A .22LR is about 1200
f/sec and the rounds arrive pointy-end first.

That is very nice!
I tried a simpe multy coil long time ago, with photo-cells.
But this guy and his 3D printing work, and so many other improvements.. Amazing I have a power laser now as weapon in case byethen invades
here...

You just blind the target and then get it.
There is actually a small recoil force...
hard to tell the differnce between force due to magnetic effects.
but you can make the thing swing if pulsed in the right frequency.
Did burn a hole in the box through..

You can screw on filters to project things like star patterns etc..

You could use a lower power green laser of say 10mW to temporarily blind
your assailant instead, Jan. That blue one you have there is pretty
extreme for neutralising a wouldbe thief and would probably burn through
half his brain as well!
