For this project you need following materials:
1) DC Panel Voltmeter Ammeter x1
2) USB Type a PCB mount - female x1
3) 12 Position Panel PCB Wiring Rotary Switch x1
4) LED red x1
5) 470ohm Resistor x1

Buen video amigo, el selector de voltaje que colocaste, no conmuta el voltaje de salida en las diferentes borneras, por lo que puedes estar usando la salida de 12 voltios, y estar marcando 5 en el voltimetro. De todas formas la fuente te quedó excelente, gracias por compartir. Good video friend, the voltage selector that you placed, does not switch the output voltage on the different terminals, so you can be using the 12 volt output, and be dialing 5 on the voltmeter. Anyway the font was excellent for you, thanks for sharing.

your video is understood. the explanation is clear, however I would like to know the small circuit that you have removed from the power supply unit (3mn 10s of the video) and you soldered to the input of the power supply (8mn 39s) what is it called? If not soldering this circuit, can the power supply unit give the same results? And what is its role in everything you have done. Thank you

@donp.909 4 года назад

Thank you, well done and easy to understand :) BUT: unfortunately I can't find such a small (and affordable) volt/amp meter that supports enough current for my old ATX power supply: 3,3V*28A, 5V*30A, 12V*15A. I can hardly believe that the amp meter used in the video supports more than 10A. So be careful not to grill it by connecting too much load.

I have seen many videos of ATX power supplies turned into compact bench power supplies mainly for using with CB radios. Still i think its a hazardous project to turn an ATX power supplies into a bench power supply. But none of the power supplies can get over 12 volts. So to use a cb radio at 12 volts will work but not fully. I rather get myself a real power supply that gives out 13.8V DC for my CRT SS9900 Amateur radio to work correctly. Its a neat project but dangerous. You really should know what you are doing!

@temelius86 4 года назад

I'm thinking to make a project like this, but using a regulator for variable voltage and current. I should ask a few questions. Why did you assemble 3 pieces of cables for each 3.3v, 5v and 12v outputs? To provide more current from this terminals or prevent heating up this cables? What's the purpose of this dummy loads? Why did you use a rotary switch? When you set it to 3.3v, 5v and 12v outputs are still active. Is it only useful for reading current of connected port?

Hi very good tutorial and project! Can I ask you what is the purpose of the 10W 10Ohm Ceramic Resistor?

@app-o-matix 4 года назад

muflo71 If I have this correct, some power supplies (older?) require a constant load on the 5V rail for stability of the psu. The resistor(s) provide that. One possible alternative I ‘ve seen suggested for the load is a 5V led, which could be used as a power on indicator on the front panel, I would think.

@3DRC-707 4 года назад

@M. Gengo A single diode is a surprisingly effective way to incorporate reverse-polarity protection into a device's power-supply circuitry. Schottky diodes have lower forward voltage and consequently are generally a better choice than normal diodes

@sathyanp.g2000 4 года назад

Thank you for the quick replay.there is no connection between banana plug and rotary switch .so each plug is used for separate voltage ?can't we get 5v 12v etc from the same plug by adjusting the rotary switch . That is my doubt. Cold u please explain .I couldn't follow that part of the diagram

@ZeeshanMehboob 4 года назад

Sathyan P.G same question from me

@incorporeal3793 5 лет назад

@LahisTech If I wanted this to only output 12V would I still need the 10W 40Ohm resistor? I'm currently trying to get an ATX PSU to work, but it keeps switching off. I have a 10W 10Ohm resistor connected to a 5V red lead and thought I may need one on either or a 12V and 3.3V...now I'm wondering if the resistor is the wrong one.

@mk-ms7lr 5 лет назад

If your power supply is newer,then theres no reason to put a load on it.Just check the pins with a multimeter its near the supposed voltage like 3.4v on 3.3v then you dont need a load

@user-qh6ue2vq6d 5 лет назад

I have a question，after the transformation, 12v becomes 8v, 5v becomes 1.5v, and 3.3v becomes 0v. what is the reason? The digital display shows 3.3v,5.2v,12.4v.

@meranberwyck7775 4 года назад

The biggest problem in building this is the parts. When you only need one of something, to get it you have to order like 10 or more (ie. LEDs, resistors, etc). I would never need to use the excess parts. I recently built a 'useless box' and have 19 LEDs and 19 resistors leftover because I had to order 20 of them and only needed one of each!

CAUTION: It should be clearly stated that the knob does not change the voltage on any of the outputs... it only changes which voltage rail that is being monitored by the voltmeter portion of the display. If you turn the knob but do not change the wires from one set of posts to the other, you might fry your project by mistake. If you build this project, it is important to remember this warning.
