i bought a second hand semi-ded UPS for dirt cheap, replaced battery and MCU filter caps, and it was great
worked like that for 5 years or so
then it was away from me for half a year in unknown condition and then transported to me
it came with dead battery
bought a new battery, plugged it in, seemed good
incidentally unplugged the battery when it was plugged in a working (but not loaded) UPS, and something exploded inside with a nice bang and flash
have no clue why
disassembly shown a fried MOSFET
not sure if it makes any sense to try to fix it
but sadly .me is not Moscow, so can't buy loads of used UPSes for dirt cheap
the fried one is at the right: https://tinystash.undef.im/il/4Z7EYDuSqDh47tQcw4qGjUuJv9VNfVCr24nGmvB8zZ7kdZo1ZnNtfPxyAps7zXFeg5JJvp5rj8W6zNSBAwc2Epvz.jpg
no idea what it feeds, so no clue why opening it would cause a short
also some sus deposit, couldn't identify the culprit: https://tinystash.undef.im/il/2QpKK6BDiUkgcMewPmmXPCyrqKTSJPRX5JCU8JAGnECakmaiHqNgDTtoBdP7huAKvJCRL4934NokVsvwES6QBezF.jpg
i wonder if it makes sense to dig any further or if i should write it off and buy a brand new one

Почитал https://www.thingiverse.com/thing:2656288/comments и обзавидовался. Возиться с силиконом сразу стало лень.
Напечатал демпфирующие прокладки для крепления шаговиков из TPU (и укороченные спейсеры из ABS) - принтер стал ГОРАЗДО тише.

Есть нынче сетап вида "сунь пять баксов алиэкспрессу за вебку от модного ноута, подпаяй USB-шнурок и получи классную малюсенькую незаметную FHD-камеру с x264", или везде попёрли DSI MIPI и прочая ебота?

Купил четыре года назад в dns-shop "Corsair VS450", а недавно он сдох.
Внутри обнаружилось это: https://tinystash.undef.im/il/3L88WPnnrb2iaA669zYyb4FX67RJzhDTFHk7dGk1j2XkD8RRcaGJ88mBcoBbK9YfeHVCPrNFRd4RjxXKS96ogddR.jpg

I am gathering a list of people who want to be involved in the discussion around the formation of a "United Federation of Instances" which is an attempt to combat the fracturing of the fediverse and the general spreading of misinformation WRT moderation decisions.
If anyone is interested in being a part of it let me know in the replies. I will add you to the list, share the draft proposal, and we can start discussions. I have several people already interested.

> Accounting for 50% of global final energy consumption in 2018, heat is the largest energy end-use and contributes 40% of global carbon dioxide (CO2) emissions. About 50% of total heat produced was used for industrial processes, another 46% was consumed in buildings for space and water heating and, to a lesser extent, for cooking, while the remainder was used in agriculture, essentially for greenhouse heating.
