inventor aw - This Device is very helpful ,, you can make at home

I am considering subscribing but you must please change this type of music!👌

Very cool 555 tester idea. I would have put the capacitor on its side so you can install the chip more easily. Also maybe a momentary switch in series with the 5V rail?

This rules! ;-) ... And funny background music!! Thank you!

A great idea with the 555 timer chip tester, and the idea of testing the integrity of the USB port, or on this basis, it can be possible to determine the integrity of the operation of the motherboard of a computer or laptop

Neat ideas. I'd modify the 555 timer to put the IC Socket on the other side (with needed wiring changes), so you're not fighting the cap or the Speaker when installing/removing

Super project sir...👍♥️

I might take this and modify it with multiple "channels" where each "channel" is a different size seat to test multiple size chips. Good video, thank you.

As always. Excellent ideas. Very resourceful and clever ideas.

Good projects, and easy to accomplish. Subscribed and thumbs up. Looking forward to more.

Projects are good. IMHO, in the 555 project, I would include some current limit such as a 100 Ohm 0.5W resistor in series with the +5V rail. If you are testing 555's at random you could be introducing a completely shorted device and that could blow your battery pack or even your computer USB port will complaint. Also, is a bad practice to make a "hot" IC insertion in the test socket when you are testing probably failed IC's. You should insert and extract the IC with no power applied.

I don’t mind the music genre per se but the volume is way too loud, I could barely hear your voice. Btw the 555 tester was good. I didn’t like the “magnetic activated pendrive” so much because it just seems an unstable connection, just imagine the magnet disconnects during a big file transfer. That wouldn’t be fun. Other than the fact that it can damage data on older HDDs that may be inside of the computer.

Fantastic video, Thank you for posting, please post more cool idea's.🙂

Continuous buzz only means the 555 isn't working under certain circumstances. It's not a 100% perfect test when using those types of IC sockets either.

Здравствуйте! Где то на моём канале есть видео, которое я выложил года три назад, как на основе геркона ещё в девяностыегоды, а точнее в 1995 году, сделал противоугонное средство, установленное в автомобиль. Помимо геркона в том устройстве задействованы тиристор типа КУ 202 и штатное реле, которое включает какую то систему с автомобиле, позволяющую после соответствующих манипуляций запуск двигателя. В нескольких своих мультиметрах так же применил геркон для выключения питания без переключения основного выключателя. Такое тоже есть на моём канале! Каналу всего доброго и развития!

I love your music even if it’s alittle bit loud!

I like the 555 timer tester. 👍🇮🇪💚🙏🏻🙏🏻

Nice projects 👍Headcase music 🤣

With this project I can test IC 4558 or do you have one for that?

instead of the reed switch, just encrypt the data. And don't worry about someone formatting the thumb drive since if they have it, they can just toss it anyway so the data is lost regardless.

I liked the improvement of the flash drive, but such protection is not serious, watching this video, everyone will be able to test the Flashka with a magnet and there will be no secret. The timer 555 check device is nice, but there are many other microchips that you can’t check on this device ... Does it make sense to do it?
