should work even better if you swap out the led for a headphone speaker. it's much easier to differential signals with sound than with a flickering light.
@@zagatozele old broken radio and a busted USB cable, those really are extremely easy to find parts. Pretty much any older electronic device is gonna have a few BJTs, LEDs, and resistors, and USB cables are everywhere.
@@grimsdespise6774 technically yes, but it works like capacitor, the coil thing is half of the capacitor so it can be straight piece of metal amd it would be more effective
@@creepyloner1979 The problem with that, though, is this assembly of parts, as neat as it looks, will get gunked up quickly. Especially the exposed coil. For any considerable amount of use, like in my line of work, store-bought tick tracers 100% lol Edit: autocorrect
Thats a good project to learn signal amplify with Darlington or multiple pair of transistor and DIYer persons enjoy from a handmade tool instead of china maded things 😀
You know you can just buy these right, and they're also a lot less sketchy, and actually insulated so you don't die if you touch it to something you shouldn't have.
The time and bill of materials needed to create this (especially the time for a person with the skill to do so) far exceeds the cost of a $5 ac detector. Heck it's probably even more costly than the ones that have the out checker on the back that tell you if you wired it right.
Well, Every Cable, that got some electricity generates a Meagnetic field, this simply detects that Magnetic Field. But cudos to the Uploader, it looks so simple, yet it can be realy usefull, when you don't drill into cables in a Wall.
Yeah, you can buy one But wouldn't it be more fun to build one yourself? All the middleaged or twenties guys who failed school and had to work at construction since 17 back away I'm not gonna argue with you
I'm going to make this and use it before I drill a hole in the wall of death in my house, it's got cables all over the place. Thanks. I'll let you know how it goes 😏
물리학과가 말합니다 원리1 전류가 흐르면 주변에 자기장이 흐릅니다 앙페르법칙이라고 하죠. 보면 스위치나 스위치에 연결된 전선은 전류가 흐르니 앙페르 법칙에 의해 자기장이 흐릅니다 원리2 반대로 자기장이 변화하면 근처의 전선에 유도전류가 흐릅니다 패러데이 법칙이라고 하죠. 결과1 그러면 스위치에 연결된 전선 주위로 전기장이 발생하고 그 근처로 저 코일과 트렌지스터로 연결된 기계를 가져가면 자기장에 의해 유도전류가 발생하고 그 유도전류가 전구에 불을 키게 되는 것입니다 결과2 그래서 안쓰는 콘서트는 뽑아라는 말이 콘서트를 뽑지 않으면 전선 주위로 계속 전류가 흘러서 대기전력이 소모됩니다
And I hate the cold solder but the camera over my eyes is a little hard to solder. I've had a soldering iron in my hand for over 20 years and I know how to solder.
Terrible idea. Never trust your life to homemade electric testing equipment. Especially when you can go buy a no-contact voltage detector from home depot for like $7.
@Vulpes Ignis and didn't reply, he knows I'm correct. This is highly irresponsible to post this kind of content when there are stupid people out there who will do this.
instead of building this just go and study about Darlington pairs and other transistor cascades. It's a 5 minute topic but you might require it sometime in the future.
