Failed electrical engineering major here - it turned out I was built to be a scientist, not an engineer, but it took a year of EE classes to figure that out.

Regarding energy storage, capacitors aren't much different than batteries, but they can charge/discharge faster, have lower energy density (units of stored energy per units mass), and self-discharge faster, hence why they aren't used in place of batteries. For something where weight and volume aren't an issue and with no need for long-term storage, like a solar-equipped house, a huge cap would be a great option. I'm trying to figure out how to build one of what's described it the article now.

The rate at which a capacitor discharges varies just like a battery, proportional to the resistance of the circuit. The reason most folks associate capacitors with "shorted terminals go boom" is the maximum rate of discharge on a capacitor is much higher than a battery, plus some capacitors operate at a much higher voltage than is practical for a battery, increasing the likelihood of generating a small arc. Shorting the terminals with a conductor makes a low resistance circuit so it just dumps its charge, whereas a battery would max out at a much lower rate, typically making a toasty wire versus a vaporized or melted wire.

Speak for yourself, I might make one!

I'd punch the alleged deals into camelcamelcamel to find they'd been similar for years. I've even found prices that went up!

Dude, these are SO fucking cool!

Edit: this picture is getting so much mileage this year.

People are much nicer as a whole here. I was on Reddit for years and I started to dread seeing I had replies to my comments. I'm actually excited when I get responses here.

It helps a ton. Facial massage and neti pots help me survive the worst congestion.

Oh shit, I didn't know about ESPhome. There goes my free time!

No kidding. I have a disability and was fired back in January for it (investigation and lawsuit pending). There are so few jobs I can do and it really sucks.

 
 

I just had three "very special" Craigslist experiences in a row and wondered what everyone else deals with when selling things online.

Starting with the time-honored tradition of copying a meme I just saw.

I'll nuke this community if we get 196 back (edit: if the community agrees to nuking, fuck unilateral decisions)

Seriously people, use the fucking fan. It clears away odors and covers up the sounds of your dropping a deuce. If you want to stew in your shit smell and revel in the music of your magical poop plops, do so in the comfort of your own home. If you're a guest and the bathroom has a fan, turn it on. We don't want to share.
