That's the fun of out of context comics. This one doesn't state that the goal is to replace the sun, but to equal its brightness.

Suppose batman has a new sun-powered gadget, except well he's Batman so it needs to work at night. But he'd need 455000 moons to pull that off, and yet he does it somehow.

I'd read that comic...

Why not? There's a bunch of applications where that is a requirement.

The Lunar Laser Ranging experiments are a fun one, I think. Scientists shoot lasers at mirrors placed in the moon and measure the trip time of light to calculate the distance of the moon to the millimetre.

However:

Out of a pulse of 3×10E17 photons aimed at the reflector, only about 1–5 are received back on Earth, even under good conditions.

Too small, but an interesting example.

In many countries, and across history, universities are the breeding ground of anti-establishment protests. Young people with a strong desire to change the world, not yet shackled by the burdens of society and all that.

Except that in the US, students are chained down with massive debt they can't escape from, so that they can be kept on a leash.

A mirror doesn't generate its own light either, but would you try shooting a weapons grade laser into one and pointing it at one of your eye sockets?

Also the Earth would probably be pulled apart under the gravity of all those moons, which will likely solve many of the present day issues so let's not rule that out as an option is all I'm saying.

Going by experience here, the American WILL question this idea the very seconds the foreign has a diverging opinion or calls them out on something.

Looking at US politics from across the pond, there seems to be a healthy dose of activism, except it's exclusively online.

Unfortunately nowadays this is totally irrelevant, because it's so easy to counter by anyone with money to burn.

When people have actually gathered (mostly unions) they have found success.

Judging by the backlash I saw online on that butter recall because of the missing "contains milk" statement, it seems like few will miss the regulations.

In the long run, looser regulations could prove to be a Darwinian solution to most current issues.

Ah yes the embodiment of the French Revolutionaries spirit. Paraphrasing the slogan, wasn't it something like

"wake me up my brothers after the king gets beheaded, why would I go out with my pitchfork if nothing's gonna happen".

That was a wild rabbit hole...

The Beagues paid 15 cents for [their infant son's] stamps and an unknown amount to insure him for $50, then handed him over to the mailman, who dropped the boy off at his grandmother’s house about a mile away.

Wow how did they get this photo of a moving subject in a camera from the 30's. I'm impressed

Hi everyone!

I'm trying to control a "dumb" led light strip segment with an ESP-01S. This is fairly low current, the strip will pull 150mA-200mA max (depends on... artistic? needs).

I have two NPN transistors (2N2222), one to control the 12V supply to the white "channel" and the other the red+blue (don't need the green).

I had to pull-down the gates as I had some flickering, and it works perfectly if I manually connect the GPIOs after the ESP-01S boots.

The ESP will boot if I have the RX pin (GPIO03) pulled down on boot, but not if I pull down any of the others.

I'm not smart enough to come up with a way to have that extra pin I need to be high only during boot, while the gate it's attached to needs to be pulled down...

Any thought, other than getting something with more IO pins?
