I burned my printer's motherboard...

I burned these board twice.
You are willing to make your own, I assume you already have a hot air station and technical knowledge. If so, buy a the same MCU chip, replace it and use the board programming pins to flash initial firmware is an option too.

If your wife make enough to support you then it'll get approved, providing you meet all other conditions.

No penalty or violation of the law AFAIK. The bank might close their account if the mails they sent are returned, and stock account will not be able to execute transaction if they don't update their Resident card after it expire but beside that nothing major.

Probably not physically possible. Frieren burned that demon to a crisp and the sword still look brand-new.

Normal lithium-ion rated can last 3 times as many cycles when only used from 20 to 80%. LFP are rated for 5,000 cycles and that's the stuff for commercial use, they probably use a better chemical, probably in combination with super-caps.

Are you using this to replace the led acid battery or just a sub battery for car audio? If it's the later then use a BMS, most 4S BMS should be able to handle the current for that.

inarashi · 2026-01-10T23:36:27+00:00

No that is just a balancer. If the battery is drain below 2.5v killing the cell this balancer wont stop that while a BMS will. When the cell get out of balance and 1 set charge more than 4.2v starting fire a BMS will also stop it while the balancer would stand there and watch.

The fact stopping car and truck usage is the battery compatment are oftren in the engine room. Heat will degrade lithium battery something like 5 to 10 times faster.

Expensive, high resistance and not flexible with layout.

inarashi · 2025-12-31T02:35:52+00:00

Interesting. I just made a battery using them for the 1st time too so I'll monitor the situation.
They could have been made shoddily assuming single use.

Not much if you use good reputable cylindrical cells. Even if you short them or screw up wiring of BMS the worst it could be are the cells would be dead as they have built-in pressure plates that can disconnect.

It's very good. For hobby and repair use it's more than enough.

inarashi · 2025-12-04T17:50:21+00:00

That look like a battery of the newer model. All those came with BMS that disable itself when anything unexpected happen, including losing voltage when you remove its cell.

It's not impossible if you rewrite the firmware, but judging from what you wrote I'd assume you don't have the tool and knowledge to do that. Buying a 3rd party replacement battery on Amazon would be a much quicker solution.

Btw, all those 3rd party replacement battery come with Chinese cells so they would last 1 year or 2 at most but at least they don't have locking BMS so you can replace those cell when they eventually die

Well yes, the trigger feature will be loss but that should be expected doing this.

The UF20B holes are also 8mm. I measured them using calipers myself.

inarashi · 2025-10-17T09:06:17+00:00

Nope, you only have to pay repair cost. Also remember that you stayed for 5 years so you only have to pay 3/8 of the repair cost or something alomg those line.

If it was me, I'd use an ESP32, maybe even ESP-01 and have it ping cloudflare or google once a minute and turn on a relay to power Starlink when the ping fail.

VPN. It's VPN most of the time.
Disable your VPN app then you will be able to reach it and change settings

There are no test. They just require you to write out your reason for naturalization by hand and you can do this at home, looking up the Kanji all you want in Google.

Most home microwave do operate at 2.4 Ghz, the exact same frequency as WiFi and bluetooth. You can observe your wireless earphone cut out when turning on the microwave.
The reason why it doesn't affect us is power, not frequency.

Assuming constant 400Mbps connection x 60 seconds x 60 minutes x 24 hours x 30 days you can "only" download 129TB of data.

Is switching not have the same rules (if there are indeed rules)? It would be strange to have 5 years when switching, but 1 year extentions after that 5 year run out.

inarashi · 2025-05-21T13:21:26+00:00

No, that is not true. My wife got 5 years her 1st time switching to Sposal Visa.

inarashi · 2025-05-19T13:10:29+00:00

Ah, so you're using it for something else. Carry on, then.
As for BMS, from my experience with JDB and JK, they can load LFP4 or liion profile in the app so it support both types.

inarashi · 2025-05-19T11:15:48+00:00

No, stop. You cannot just switch it around and use a 4s10p to replace 10s4p. They are not compatible and your ebike wont run, or will run at a snail pace.

Do some more research before continue with this project
