Tried to build a dummy CR2032 battery to power an AirTag. Did not work. May just sacrifice an AirTag and solder leads directly. #cr2032 #tinker #electronic #AirTag

Geräte mit #CR2032 #Knopfzellen einfach nicht draußen aufstellen!
Lohnt nicht! Bei Frost sind die Dinger einfach Schrott.

@libreleah Every PC / Laptop repair place I knew had like rolls of #CR2032 cells ready and most offered customers to swap them out for like €5 (similar to watchmakers and jewelers do) incl. a full restore of the BIOS/UEFI settings...
Mostly by just jumpering the power contacts and keeping external voltage on until a new cell was inserted.

Простое, но очень нужное устройство. Сигнализатор открытой двери холодильника
Приветствую, Хабр! Данное устройство было изготовлено и установлено уже более года назад. Работает отлично и «спасает» от возможных проблем с компрессором. Предыстория такова. Шел март 2023 года, на носу день рождения супруги, полный холодильник продуктов, через пару дней ждем гостей. Открываю дверцу холодильника и понимаю, что в нем нисколько не холоднее, чем в квартире…

Just #replaced the #cmos #battery on my #slimbook #laptop.
It was a little difficult to #solder directly to the #cr2032 battery, but scraping the terminals I managed to do it. Then i heat-shrinked it and reinstalled. The new battery is a little bigger than the original one, so I reinstalled it without the thick double adhesive present from factory and it barely fitted. Hope will last longer, because the only two years if the original one were not really impressive, if you consider that my older laptop didn't have a cmos battery at all: it used the main rechargeable battery, and it's a sensible choice imho...

The #KITT effect circuit that I designed and simulated in #verilog actually worked at the first try. I'm surprised.
It's done with a 555 and a bunch of 74 ICs. Nothing fancy.
It's also totally useless, unless one needs to drain #cr2032 batteries watching #blinkenlights

TIL: Es gibt wiederaufladbare #Knopfzellen..
Direkt mal ein Set mit 4x LIR2032H und Ladegerät zum testen bestellt für die ganzen #Chipolos und #Smarttags
Bin gespannt wie gut die funktionieren..
@flyingsaceur @polpo can't you add a #CR2032 to it?

Hey #HomeAutomation and #Electronics and #Hardware folks, what do you pay for #CR2032 and #CR2450 #batteries?

Grundsätzlich mag ich ja diese #Ikea-#Tradfri-Schalter. (#E1743, bzw. 704.085.95)
Klein, symetrisch, ein/aus und Magnet auf der Rückseite
Aber je länger ich mich damit beschäftige, desto mehr fällt auf WIE scheiße die wirklich sind.
Wackelige Software - okay, das haben scheinbar fast alle #ZigBee-Geräte
#CR2032 gehört verboten
Ein/Aus ist unsinnig wenn der Schalter keinen haptischen Zustand hat (einzelner Taster wäre oft besser)
I/O kann man optisch kaum erkennen - man tippt IRGENDWO drauf
Lately, all #CR2032 batteries have this obnoxious transparent casing that forces any kid who wants to swallow them to run around with scissors as well. #safety
Batteries form Amazon- why are they so cheap?

der #Tuya #ZigBee 3fach #Schalter ist leider ein kleiner #Stromfresser 🤔 2 normale AA Batterien dran gefrickelt ist die bessere Lösung als immer die #CR2032 zu tauschen - mal einen Adapter bauen wo die externen Batterien unter dem Taster verschwinden
