Hey! Apologies if it's not the sub for this.

So I have the device above for 6 years now but it has some issues, like constant crackling and popping noises from the speakers that starts off stupidly loud when the device is powered on and it subsides in like 10 minutes but never goes away completely. Anyway, whoever I took it to gave up or told me it was unfeasible to fix it based on costs, but nobody really knew what was the issue.

Some specs are 10" sub, 300W RMS, 2x75W sats (5Ω?). Forgive me but that's all I know and that's where my (lack of) knowledge ends in general.

So I'm wondering how difficulty would it be to give it a new life with a completely new power supply, driver or whateve

Hey! So point is in the title but I'm wondering if it's just garbage PLA filaments or some other issue. Like I've tried two different black filaments from Amazon which both melted like rubber when I just extruded them in the air. Blobbing into a thick teardrop if that makes sense. I went up to 240°C with one out of annoyance but it clogged completely mid print. I also generally use 195-200°C regardless of what is the factory recommended temp because that seems to be the best result for over a dozen filaments so far; very little stringing, good layer adhesion and my thermistor is a few degrees higher than room temp (after like a day of no use).

So I wrote those black filaments off (and it so

Hey, so recently I've been using disposable devices called Escobar but I finnally figured out what juice they use in the factory from the guys who make it but it doesn't taste/feel the same in any of my devices (up to 1.2Ω) but does taste the same if I disassemble, refill and recharge the device (crazy how wasteful these are with literally rechargeable 280mAh li-ion cells but no charging ports).

So I took a multimeter to an Escobar and it measured 4Ω on the dot so that's what I'm after. The liquid is also fully in cotton so it's not leaking at all regardless of liquid, which is a plus and it's new to me (I only have old tanks and an Uwell Caliburn G2).

Ideally I'm looking for a slim device

I picked up a couple of Sunlon 12V 5020 fans and buck converters but I could only find models for 5015 fans and Hero Me's massive list of parts but no clear information just links to patreon.

Single or dual 5020 doesn't matter.

Also, anyone using fan ducts from PLA? I think with always having some fan speed it should be fine but I'm not sure.

Hey, I'm looking into getting a solar setup with an inverter that's using the solar output directly first but supplementing it from the grid on the fly BUT it does not put electricity back to the grid. That is very important because here in the EU I'd have to get a permit and would be limited in many ways and possibly even taxed.

So I think it needs a hybrid inverter? But at this point I'm not planning on having batteries, maybe later but I'd like to have that as an option later.

Point is to use solar first like an off-grid, but supplemented from the grid live and just "waste" the excess solar production instead of sending it back to the grid.

What's the most reliable inverter brand or mo

Hey, so instead of 4 wires the device works perfectly well with a single ~2.5Ah 18650 cell. My issues is that the device cuts it off at 3.5V.

My question is, anyone have any experience with stuff like this? Do I need to include a BMS that's more laxed and figure out where to wire it (would be quite a challenge)?

I mean now a 18650 cell getting cut off at 3.5V is barely any better than a tiny 1000mAh factory default Li-Po, which also got destroyed in the process of extraction (they didn't spare the epoxy, hell they used just as much as the battery!) so I can't measure 4-wire Li-Po cutoff voltage.

I'm sorry if it's not allowed and feel free to delete this, but since this sub have a tech-savvy approach and we/I like to mod stuff to be 18650-powered I was wondering what kind of 3D printers you guys use.

I'm looking to get one for years but now I really want one as I can see a bunch of really great ones on the market. I can't wait to make custom housings/backplates/etc. to replace garbage, low-capacity pouch cells with proper 18650 solutions, going from duct tape and hot snot to proper 3D printed solutions!

Hey, I'm from the EU (R32 coolant) and I have a 3.5kW Midea Ultimate Comfort and a very pricey 5kW Daikin Ururu Sarara AC in different rooms far away and I've been battling both of them for years because they both smell like what I can only describe as 'geriatric mold' when cooling even after a full cleaning including disassembly (not just spraying inside).

The smell comes and goes almost instantly (lasting like ~30 minutes), but what I've recently noticed is the smell does not randomly comes, but 100% once they bought the temp down to target and just start idling and running the fans. But then it always happens! Hence, I've set my Daikin to 21°C and literally only turn it on when it's hot

Hey, so it's an update on this post. Now I replaced all the cells and the pack does power tools but the charger still throws an error (red blink). I can't tell any difference between measuring the 4 leads between this and a working pack.

I also couldn't find any results for buying a controller/BMS/board for this pack (FMC688L). Can I reset the controller/BMS by applying voltage manually like it is the case for some BMS when they trip? Or some kind of fuse tripped permanently and I'm SOL?

What can I do here?

Hey, so one of my packs threw an error on the charger and won't charge but it still works. I took it apart only to see this: https://imgur.com/a/UoArOk4

Not sure what happened there, there's no way it was exposed to water so maybe one of the cell leaked? Either way, one cell in the corner is reading 2.3V while all the rest are reading 3.5.

Under the wrap there's just gibberish (UG8R28 003172). The smaller 5-cell 2 Ah packs have teal Samsung INR18650-20R (M SDIEM 125) so I'm guessing these red ones are similar in specs (edit: I tested one for capacity: 1990mAh). I'm planning on testing them all and use them in other projects if they have low internal resistance and decent capacity. Except

Hey, is there an app that I can use via bluetooth instead of a laptop with the given software?

If so, would you be so kind to post a few pictures?

I'm contemplating getting a 12 Pro but I'm reading very different things about its battery life. I'm basically curious about on screen time and deep sleep drain.
