@AlizTheHax0r I had a chinese electric bike, that has such a 3-pin connector at the 36V battery. I could bet, exactly this cable connects the cells inside the case

Do I win AliExpress cursed item competition with this

@ronsterd89 a book or two, and probably a dirty dish

@daisyldixon tststs... no backup, no mercy

crying and throwing up, my Mac just seemingly deleted my draft paper which had all my thoughts in that I’ve been working on for weeks. This is the error message. I went to ‘save’ it and Word just said the file was missing. The file is not in my trash. Please someone help me recover it 😭

@maddenifico look at the "education" system in USA. Kids ar trained to do, what te superiors say, and the graduation tests are unified with the goal to make them as easy as possible for teachers and kids. And you could no more learn what you have missed, because community colleges are cosed.

It's amazing how many Americans blindly accept fascism if it's wrapped in the Star and Stripes.

@Afghan_Engineer you souldn't show this to others. Its VERY RISKY! Put your soldering iron just one second to long and the battery will react violently because of too much heat.

Lithium battery soldering.

@mimu_s It's part of the installtion now. On purpose!

最近ウチに異動して来た若い子が相当な才能の持ち主。センスの塊って感じで目が離せない。

@longdepzai_n buy cheap, buy twice. no mercy at all

@LePapillonBlu2 if you are US citizen, for most of the poits, you have to get rid of your whole government and elect a new one

WHO’S WITH ME?? 💙🌎

@DLCampanile perfectly normal in a northern europe sauna

Accurate.

@otokyo Shuji Nakamura The inventor of the blue LED.

Name a famous person from Japan. Can you?

@MuseumCommodore big boooh at you for your not so well made picture. What you are want to show, is the rewinding of a music cassette. This will only work with regular hexagonal pens. A round pin won't do anything at all.

@nicksortor planning some awfull stupid shit making the world even worse?

🚨 NOW: President Trump is now BACK in Washington, DC after CANCELLING his weekend plans in New Jersey CBS is reporting intelligence officials have ALSO canceled Memorial Day plans, and are on standby. Something may be imminent 👀

@ElecNotes used one of these BC547 and two resistors last week to boost a pulse signal from 5V to 24V

Struck by an obsolete or out-of-stock transistor? Whether you’re repairing a classic piece of gear, prototyping a new circuit design, or dealing with supply chain gaps, you will eventually face a common hurdle: The exact transistor you need is completely unavailable. The good news? Because transistor specifications have a high degree of overlap, you don’t need the exact part number to get the job done. You just need to know how to pick a proper substitute. Here is a 6-step checklist to safely narrow down a cross-reference or replacement transistor without blowing up your circuit: 1️⃣ Verify the Polarity & Material First It’s the absolute bare minimum: NPN must replace NPN, and PNP must replace PNP. Equally important is the material. Silicon (approx. 0.6V base-emitter drop) and Germanium (approx. 0.2V–0.3V drop) cannot be casually swapped because the circuit’s biasing relies heavily on this voltage. 2️⃣ Check Voltage Breakdown (VCEO/ VCBO) Ensure the replacement transistor can withstand the circuit's maximum voltages. The replacement ratings should always be equal to or greater than the original. (Pro-tip: If you don't have the original datasheet, aim for a maximum operating voltage that is at least twice the circuit’s rail voltage). 3️⃣ Match Current Handling (IC(max) The substitute transistor must be capable of passing the required maximum continuous current. Your replacement's maximum collector current (I_C) should be \ge the original. 4️⃣ Look closely at Current Gain (hFE / beta) While gain inherently varies significantly even within the same batch, you want a similar range. In most general-purpose circuits, choosing a replacement with a slightly higher gain is perfectly safe, but a lower gain might starve the circuit. 5️⃣ Watch the Frequency Limit (fT) Make sure the transition frequency (fT) is adequate for the circuit's operation (especially in RF or high-speed switching). However, beware going too high! Choosing a substitute with a massively higher fT than required can inadvertently introduce unwanted circuit oscillations. 6️⃣ Don't Ignore Package & Pin-outs Physical sizing matters—especially if you're dealing with heatsinks or compact PCBs. More importantly, double-check the pinout configuration. Just because two small-signal transistors look identical (like TO-92 packages) doesn't mean their pins are both E-B-C. A mismatched pinout is a quick way to let the magic smoke out. What if you can't find the original datasheet at all? You can still reverse-engineer a safe bet! Check the operating voltage of the power rail, deduce the material by measuring the base-emitter voltage drop of a working neighbor transistor (if available), and gauge power dissipation limits by matching the physical case style. What's your go-to general-purpose substitute when you're in a pinch? (For me, it’s hard to beat having a drawer full of BC547s or 2N3904s!)

@Agrieconom Nice Dice :-) My version from the metal workshop in school:

Making a crazy dice with steel and brass on lathe

@mjfree isn't there the other thing, when they went to dinner, there was a cushion on top of Trumps chair so that he can sit at the same head level with Xi and he refused to use it?

😂 Xi Jinping sat on a tall chair while Trump was given a shorter chair with a soft cushion so he sinks & appears smaller than Xi China humiliated Trump in front of the world. Just look at his scowl!

@MuseumCommodore depends on, if you are more in gaming or more to learn programming and do useful things

@NoContextBrits Looks like Newspeak from 1984

Very interesting.

@Tawadotcom why does someone rate this video as AI to promote his own channel? Has he ever seen real craftmanship? Half of the things shown, I can do by myself and some of the other things, I have already seen for buy at some artisan markets.

Wow, bamboo can be made into all these things

@ThrillaRilla369 back in my days in the 90s in germany, VW Golf was the most common car at driving school (in germany, you usually don't use your own car)

What kind of car did you use to pass your driver’s test? 🚙 I’ll go first: 88 Dodge Shadow

@potatoslav you can't tell me that americans don't know canned sausages

Germany also, for some reason, sells “American hot dogs” in glass jars filled with water? not in the fridge?? i’ve literally never seen them like this in the US ever, this is a German invention.
