I had a job where the CEO/founder regularly yells at people and punches the wall.

During citywide rollout. He and a few other people went out to buy power inverters so they can power up my PC using someone's car

Better than yelling at a wall and punching people

When I was CTO I would punch walls too. Finally convinced the CEO to get me a boxing sandbag in the office.

People underestimate the fucking productivity boost a safe anger outlet provides.

Must add, karaoke or otherwise soundproof room helps with the yelling too. (Also guilty 😁)

Kinda impressed by power inverter in the car. That is a can do attitude.

@Demolishun Except I was the only one actually doing the work lol. They were only able to power up My pc

What I don't get...

Unless power "inverter" doesn't mean what I think it does...

Car batteries are DC, so they don't need any apparatus to hook to a computer, save maybe voltage conversion, which is easily done with a transformer. Hell. Most laptop bricks handle the 12V of a car battery.

@CoreFusionX you don't do DC voltage conversion with just a transformer.

@CoreFusionX I'd assume they mean a tower PC. Also, do car batteries emit a steady 12V? Last time I tried to do something similar, I was told that the 12V actually swings between 15 and 6 depending on the charge and other factors, so I shouldn't run a hard drive on it unless what I want to do involves destroying data.

@lorentz Car electrical is some of the worst output you can get. The battery will actually smooth out the output of the alternator a lot. It is better to convert than have it fry your laptop. Electronics in cars are hardened to prevent them dying.

@electrineer Please plug a keyword here, I want to learn electric engineering from DevRant the same way I learned about horizontal scaling and various other topics through various experts' angry responses.

@lorentz do you want a keyword for DC voltage conversion? SMPS.

@lorentz

My bad. Terrible case of lost in translation. What I meant is called a "converter" in English.

Still, feeding DC into a bridge rectifier (which is what laptop bricks are, afaik) results in DC with a slight voltage loss.

Don't really know if the voltage output of a car battery is stable, I guess the same capacitors in the PSU that protect against voltage spikes would act just the same here.

Probably unsafe long term without a more advanced regulator, but doable in a pinch, particularly if the car ain't running.

@CoreFusionX If the car isn't running is key here.

Can't we simply use the car's battery? Without actually going through the car? There shouldn't be power fluctuation.

lol. I'm going to frame the problem a bit by specifying it was a tower.

Keep going, don't mind me
