3 Simple Inventions with Electronics

In the first video i will be using an old Computer power supply from an old CPU to produce 3.7v, 5v, 12v, 24v DC for running different electrical and electronics appliances. In the second video i will be using some old laptop batteries and a BMS to make a 12V battery pack which i will use to run a 3D printed water pump. In the last video i will be using an old transformer from a dead CD player to make a variable power supply.

The purple wire is the "+5volt standby". It provides power whenever the main power is plugged in and the switch is turned on at the back.

The grey wire is the "Self Test". It provides 5v whenever the unit passes it's own tests and determines that it's in working order as best it can.

Charging the battery should go through a current-determining circuit to allow the electricity to cut off the full charge. Direct charging is dangerous and causes the battery to deteriorate more quickly.

The brown wire must be connected to the orange wire, it's the 3, 3V sensor, it helps the 3V voltage be more stable, and you gonna have 3, 3V like the pattern.

Ich finde es auch toll wenn man alten kaputten Sachen noch einen neuen Zweck gibt. Aber wo sind jetzt genau die Erfindungen?

2:22 it isnt motherboard cooling fan, it is cpu cooling fan

😀 I think this is good for the world, wish more people would reuse stuff instead of just throwing away!

[marcfruchtman]

While I admire this process, I am curious how many hours did it take for you to prep the power supply?
Also, I am not sure how useful this will be for charging without some circuit to prevent overcharging...
Don't you also need something to limit the charge rate?

Wichtig the burning Laser you can make a nice laser Plotter...

Cảm ơn bạn đã chia sẻ cách sử dụng cục nguồn ATX của máy CP rất tuyệt vời.Mình ko biết nhiều về điện tử, nhưng thấy môn này hay rất thích học; nhưng mình đã lớn tuổi rồi; rất tiếc, ước gì ! Các bạn trẻ nên biết ngành này lợi ích lắm.Cảm ơn Thầy dạy mình ko biết tên.

When he tried to eject the floppy disk 👌😂😂😂😂
Oh no not with lithium battery cc/CV charger very dangerous Just solder correct size wire lol

ужас, у него есть 3Д принтер, но нет переключателя

I, m sorry The Professor you dont know what is the two wires? |Ask uncle Google he knows everything you are trying something but you don, t know. In this days you have a lot off help and answer on the internet so like Lokpique say to you: The purple wire is the "+5volt standby". It provides power whenever the main power is plugged in and the switch is turned on at the back.

The grey wire is the "Self Test". It provides 5v whenever the unit passes it's own tests and determines that it's in working order as best it can.

You could figured out what each wire was just by looking up the molex pin-put and noting which colored wire was connected which pin.
In other words, there's no need to follow the pcb traces.

THANK YOU SO MUCH . GOOD VIDEOS and GOOD TUTORIAL

[alexcarm]

guy knows his stuff where it comes to application of different voltages and his soldering is on point but with his disregard for correct wire gauges and potential environmental hazards not to mention the use of salvaged items which in some circumstances should most definitely not be (e.g. lithium batteries) he is an electrical/lithium fire waiting to happen. I also didn't see any evidence of him ensuring that the (clearly salvaged) capacitors and transformers he was using were properly discharged before he started poking around which if a high enough current is present can cause instant death by electrocution. Be careful if you plan on replicating any of his activities as he failed to point out the huge dangers involved. Especially when it comes to dismantling an 300W pc power supply! It is important to know that just 0.2Amps across your heart can kill you and the PSU he took apart has a minimum output of 0.5Amps so if you make a connection that runs from one of your hands to the other, you could die.

Thank you very much for these vídeos, congrats!! 👏🏼

Sir are you believe recycle energy system,
