lets drop some acid and study the chip. 🤣 great phrasing 😁

is there no beep sound on continuity test on the multimeter?

Is it possible to dump the entire SIM card and then crack the 4-digit PIN it asks for when inserted into a mobile phone? I’m looking for information on this. If there’s a video specifically about this, I’d love to watch it. Thanks for documenting the decap process of the SIM card!

I read that there is a new silicon version with fixes. How can I differentiate between them? What is the marking on the package?

Requires a PHD in electronics to understand it.

Many years later I'm still using the original 6 slim bulbs I'd put in the over mirror fixture in the guest bath and they're still fantastic and working great with an old style touch stepless dimmer. Got them when they first came out and could only wish that newer ones around the house had worked half as well. 🎉🎉🎉 note: Mine are the 60w equiv. bulbs. Also, at least from a distance of roughly 5 feet there's no buzz .. possibly also because I rarely have them turned anywhere near full brightness. No noticeable flickering either though I'm sure instrumentation could easily find that. *Cheers.!

They are out there . Some radioactive bmw’s found their way into belgium . There are bastards out there selling cars jdm’s & high end stuff for some scumly profit .

Hi what it is the name of this buzzer please

Does anyone do this at scale?

How do you get the die flat under the objective of the microscope? So you don't loose focus when you move the die under the objective?

It's a sad state of affairs but I am impressed these days by anything using a real chonky-chonk switch that actually cuts power. That said, I'm pretty sure my not-quite-as-good Tekpower TP3005T's switch is even chonkier than this one. I haven't opened it up yet, but I would not be surprised if it was switching two contacts; it is loud and you can even tell from pitch whether you're turning it on or off. And I just realized the numbering scheme matches between the two. But I don't think I can actually get 5 amps out of mine. Is the 10amp rating on this one accurate?

This at least is quiet... I regretted having bought my OWON for this reason and also has a reversed air flow that blows exhaust air by the side grilles.

It would be interesting to see what the die on the Casio Classwiz calculators looks like. I tried to do this myself but failed as I did it with brute force.

That switching transformer seems a bit anemic to have 300VA moving through it.

It looks like the model SPS-3010M has an output button on it, which is nice. Its also cheaper, oddly......

The blinking light is for self defense it disorients the attacker! Worthless?.... Wow! It's a "tactical flashlight! Set up to attach to a gun or rifle!

Put the reverse diode on the output.... It will save your PSU. Something that fails short. If you accidentally plug in a battery that you're charging backwards the diode will short and keep the remaining magic smoke inside.

Brief and concise, I like.

Dirt cheap too. Would be pretty much perfect for me, as I usually don't do anything too exciting here at home. Be nice to have for the usual low level troubleshooting and repair stuff I typically do. Very neat.

They can print any logo you like.

The output capacitor could defiantly cause a current spike beyond what the current limit is set for. As you said, probably a trade off for lower ripple. Would be nice to see the measured ripple with and without the cap.

Really enjoy these videos. Thanks for sharing your knowledge.

Thanks for show me how it works! I only have used my strobe once and that was to signal a cop at night where I was. (Called in a deer hit by a car that needed to be dispatched) Although I still probably could have just waved the light side to side and got the message across. Good for signalling. They claim for attackers to but honestly I think I'd be scared and not get the sequence right for that crap. Now on my bike mounted flashlight I LOVE the strobe! So many people pull up to the sidewalk to see cars blocking my path. The strobe let's them see me in the day time so they can move back. On a handheld flashlight I think strobe is only practical for getting someone's attention far away. (Not easy enough for a surprise attack AND can disorient you if indoors with the splash back light off walls) I hate more that like 3 settings. I like high low and strobe but ALWAYS want the first press to be 100% power solid bright. If I need a "lantern 40 lum light" I'll buy a dedicated lantern (which I have and does the job BETTER) Sort of like these gimmick "survival" flashlights that have a weak LED and then like 6 twist off compartments making up the body. Like NO you couldn't use that thing as a club! I like my simple aluminum 3 cell D flashlight that I can see very well with.....easy to find batteries....and can go "old school COPS" episode and use as a club. Any multi tool survival anything is usually a gimmick unless we're talking about a Leatherman style multi tool. The Leatherman style tools aren't perfect but still functional very well all things considered. Flashlight multi tool.........."Get outta here!!!!!"🤣 Sorry rant over GREAT video!

Thanks so much! I've watched your videos for a while and love the detail you go into, it's extremely educational to an up-and-coming board-level wannabe troubleshooter like myself.

Gacha termometer 4:5

Would you know if the probe itself is a 1k type? Etc??

Thank you. Your video gave me the solution. Thank you.

Mine 305D got bad while charging a 12 Ah lead acid battery. Output is coming as 50V uncontrolled. Can anyone share the schematic?

You can trim the plastic shield from the standard leads and use it with these meters, which you will have to do as the included leads are dangerously bad

really cool stuff

Looks not all that different from the ESP-01

The 3rd edition of my favorite pocket calculator. In my opinion the cases kept getting worse. Second one feels cheaply made and the Solar II feels like a toy.

I have the "three way" variant, and it's own video on my main channel. Not bad! I like it.

Personally I've yet to see a capacitor take out a dead bulb.

Shows everything but how to separate the motor from the head. Which is where I am stuck

Sir.....The oscilloscope in use exhibits limited fidelity in rendering the output waveform due to its restricted bandwidth of 100 MHz, which is insufficient to accurately capture the full spectrum of a 40 MHz square wave. Specifically, the device fails to process the energy of the third harmonic (120 MHz) and fifth harmonic (200 MHz), essential components in reconstructing the square wave's shape. This harmonic attenuation leads to a flattened output response, inherently tied to the oscilloscope's bandwidth constraints. Nonetheless, the internal view provided in the demonstration offers valuable insights into the design limitations and expected operational performance, helping gauge its cost-effectiveness.

Every flashlight i have bought on Amazon that does not have a way to just turn on and off with ONE button push, gets a one star rating. This is the most useless and negative feaure.

Had dewalt dcf 899 impact, motor smells like burning with minimum use intermitemnt working. rubbish cheap made.

Its not in series its in series parallel

It would be great if someone would make a light mini generator for those on canoe trips. It would be lighter and more reliable than solar and wild rivers have fast current with campsites near rapids or falls

Thanks for this video. Even today this PCB Holder is on sale now for a dollar in my country's currency.

Perhaps the on chip power regulator is the one that can be controlled by software. Voltage can be varied from ~0.8 to ~1.3.

...could you help me with a wiring diagram? Please!

Hey, would you be willing to take some pictures of the xbox cpu for the community? I know you did the gpu already, but cpu is needed.

where did you purchase the camera from

Will the tv flyback transformer the rectified one work to ionize the gas, i have an 8 to 10 inches ball, thank you for this great video.

I prefer my olight. Stays on the mode i have it in everytime i turn it on. Have to hold power button to change brightness. Double tap power button fast to make it flash. Battery lasts forever. Brightest light ive had. Light weight and tough. WATERPROOF. Had a dim mode that lasts for 3 days if needed. Has a super bright mode that lasts 2 or 3 minutes before it auto cancels to normal because the light gets hott for a led when that mode is used.

Blinking is mosly for sos or to alert people if you are next to a busy road so they dont hit you. If its a rifle flashlight that blinks, its to stun your target

Damn good videos and channel, keep it up.
