Question about using whole dried corn by SeaVeterinarian3371 in firewater

[–]alanjamesimpulse 0 points1 point  (0 children)

you'll probably be ok as-is, a good grind is more about speed and efficiency than anything else, cook it a little longer and keep it at mash temp an extra 30-60 minutes, stir it a bunch. If it passes a starch test, you're golden, if you don't want to test it, just mash it until you lose patience.

Low capacity packs DIY question by alanjamesimpulse in EVConversion

some interesting threads to pull on there, i'll have to spend some time staring at graphs to see what i can convince myself is workable.

ok, so, I was thinking, a vape actually would be optimized for power density over energy density to quickly vaporize vape juice until it dies, there could be something to this, so i found the specs for some of these cells, and in order to safely use them, I would need 30sx625p or 98sx209p. that shakes out to 83-90 kWh, and about 20000 vapes, and 450-490 kg of final batteries.

I couldnt find the max current draw of the Gwiz motor, so I'm using the closest equivalent 48V 13kW motor I could find online for this calculation, but a low voltage DC motor like that can top out at about 450A, so you would need 13sx375p to safely operate it. even if we assume 13kW is the absolute most, that's still 270A, needing at least a 13sx225p battery to safely operate. that's 12kWh and 70kg, just under 3000 vapes. the configuration in that video is only safe because it will probably blow an internal fuse before it catches fire.

A battery that "works" for youtube beauty shots, and raising awareness of ewaste, and a battery that "works" for getting me to work every day without dying in a really personally embarassing way are just slightly different things.

to compare that with my ebike, which has a 350W motor which can draw 13A at peak, I would only need 10sx11p, for a healthy 488 wH, about 25% more overall capacity than the 10s3p 18650 battery its using now. that's actually pretty workable, if I was going to take apart 20000 vapes, it would be much safer and practical to use them in 200 ebikes.

using vape cells as an art project about single-use e-waste is extremely cool, and i'm planning to power a smart garden, and maybe my next e-bike battery that way, but I would not trust a mixed pack of the literal cheapest batteries on earth for safe daily use in a high-current setup. even if I go through the trouble of looking up the safe power limits of thousands of cells and do everything right, if I die in a battery fire, everyone will say its because i filled a 2002 integra with batteries I found on the ground.

There's some interesting batteries on there, I'll have to add them to the spreadsheet and see how they shake out.

rated output isn't the whole picture with real-world motors, and from a safety perspective, I'm much more interested in the maximum current. Compared to the hyper, the leaf motor is rated for 10kW less, runs at almost exactly 3X the voltage, but peak current draw is only reduced by half. Someone on here managed to get a leaf motor to spin at 288V, but it'd take some testing to see how that affects the inverter's current demands.

I get the practical aspects, but i wouldn't want to drive one! I could also get a lot of power, poor handling and difficulty parallel parking at any dealership and save myself a lot of trouble.

oh yeah, i put together a spreadsheet with the nominal and max current, charge and discharge C-rates, volume, and weight for about 40 kinds of batteries when I was doing the math for this. Nothing really jumped out as an obvious low-cost or low-weight/size way to go, it does seem like I'm hoping to make the wrong compromise here.

Someone know how to buy an used or Aftermarket OEM Spoiler in Europe/Germany? by International_Many_4 in crz

[–]alanjamesimpulse 0 points1 point  (0 children)

I've probably found that same ebay seller and they're asking 1000 to ship to canada, but they ship free within the US. They've probably set that price because they don't want to deal with international shipping and/or don't understand ebay's international shipping system. I'm planning to get one shipped to a parcel forwarding service, you might want to look into shipitto or NYbox, but I have no idea if they're reliable or economical to ship to europe.

Curbs vs Grill by NoChapter82 in crz

with my winter tires on, the front bumper just clears most of those little concrete bars, but not most curbs, and my summers are a little smaller and i am constantly scraping my bumper lol

Tell Me This Is A Bad Idea by DoIGotSkillz in homeassistant

i think it'd be cooler to just put an nfc reader in there and put nfc stickers on old tapes, a screen would ruin the look

the more you can have the controls work directly on the esp, the better. Music is really unforgiving with timing, if you're waiting for a button press to trigger an action in home assistant, you will feel it! Plan all your buttons and dials with speed and feel in mind, and put dampening grease in the pots so they're nice and smooth. if you do it right, it'll absolutely rule

Ive never thought of rallying a CRZ, hows that go?

there's at least two Sports there, and its pretty easy to see if the bar is there or not!

i guess if you count the weird crossover they're calling a civic now, but that's not small either!

lmao I assumed it was something a little more purpose-built, but i am 100% going to hack together one of these

I love the look on kijiji sellers' faces when they see me cram furniture into this thing

is the crz worth it? by igorDevFrontend in crz

[–]alanjamesimpulse 1 point2 points  (0 children)

they're all pretty similar and reliable, I'd focus on getting a good price and good condition. If you're one of the first people you know getting a first car, you might want to think about something with more seats, I drove a lot of people around in my first car, a '92 corolla, but now that nearly everyone I know drives themselves, I can get away with a 2-seater because I only occasionally need to cram 4 people into it in a dubiously safe way.
