Fun* fact in this video: the 'disposable' vapes thrown away in Britain alone contain enough lithium batteries to make 1.2 Million e-bikes. I've been independently powering things with vape batteries that I've rescued before seeing this video. Pull out the cell, add a cheap usb charging module and you have a fully rechargeable 3.7v power source. If you need higher voltage you can put them in series and you can even get multi-cell balancing modules for next to nothing if you want to have a few in parallel for more current. I don't trust them for anything critical, but they're great for low-budget projects as the cells are completely free. My bike lights are all powered by them (one can run a flashing bike light for a couple of weeks' use), as well as various other things that had their batteries die, or that didn't come with rechargeable batteries. I also only charge them somewhere flameproof, though I haven't had any issues so far. #making#electronics#reuse https://www.youtube.com/watch?v=ehp23hrrEHY
@Weeble But it's small and it's fun to collect. :blobcat3c:
Someday, you'll feel nostalgic and still have all your original packaging. Although I worry that most smartphones will become obsolete simple because of no available good replacement battery, which was the case for an older Samsung Galaxy Note that I tried to refurbish but couldn't because of that.
Still, my point stands: Collecting original packaging is fun, especially if it doesn't need that much space.
There’s a reason why this TI-92 was $10 on eBay. Take the batteries out of your unused electronics people. Now I have spare parts for the functional TI-92 that arrives tomorrow at least.
"Over 3 billion kilograms of valuable electronics inside children’s toys are thrown away each year, and very few people are aware of this hidden e-waste"
New instance means I copy-paste my #introduction from my previous instance lol. So here’s my #intro!
I’m Bryn, (she/her, 25) and I live in the greater Pittsburgh area! I’m a #bisexual, #polyamorous#trans girl with a passion for #electronics, #music (especially #indie), and human interaction, i.e. #communication. I’m happiest when I’m among friends, lovers, or just other people in general!
I was a team lead in customer facing tech support for a home security company, but I gave that up after facing major #burnout. Now, I’m taking a few months to recuperate while my partners keep me alive, and I’m looking to start a #freelance#branding and #WebDesign co-op with one of said partners!
This account is not professional; I post #nsfw content on occasion. I spent too much of my life without confidence to let my newfound beauty go to waste! :blobcat_coy: This content will always be hidden behind a content warning, of course!
Definitely follow me if you like cute girls, relationship anarchy, free open-source software, or any combination thereof! Boosts are also very much appreciated, but please give higher priority to mutual aid requests and the like.
FDTD really is a surprisingly simple algorithm. Its core is just 3 nested "for" loops, with two multiplications and a bunch of additions. Run it once to get the electric field from the magnetic field of the surrounding grids, and run again to do the opposite. Just this is enough to model all classical electromagnetism in the universe. #electronics
