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.

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.

@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.

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.

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 man, great video! Thanks. I have a question. I made my ATX bench, and all the outputs are ok, but with a slight instability in tension, like +/- 0.02 volts, and when I want to use it to power my servomotors (controlled by Arduino), this slight instability makes my servos jitter very hard. Do you know what can be de cause and/or solution to this? Thanks in advance everyone!

@LahisTechLT 5 жыл бұрын

Did you check the code once again. This happens due to several reasons, some of non-quality servos have; gearing backlash which mean mechanical errors in gearing. so it causes for the failure in Encoder (lower feedback controller). Also, these stability happens if you don't use quality thick wires (excessive gains/ripples in pwm pulses). My advice is to upload the servo library back again and check the code specially delays. Check the ground connection of ATX ps highly recommended. Hook up a capacitor between +ve & -ve of you servo (470uF or above)

@PabloGnesutta 5 жыл бұрын

@@LahisTechLT thank you for your answer. The code is fine because if unplug the ATX from the breadboard and connect the Arduino's 5v instead it works like a charm. The problem occurs only when I try to power the servos with my atx. I connect the grounds together and all. I've been told that this supplies, specially cheap ones, tend to be noisy. I've been recommended to use a servo driver so I will probably purchase one. Anyway I like the idea of putting a capacitor in parallel with the servos. I will definitely try that. Do you think that putting one larger capacitor straight on the output of the power supply could work? So I can have one set up for all the servos? Thank you for your time. I really appreciate it. I'm very new to this and I have no mentors yet. I hope you have a great day!

@LahisTechLT 5 жыл бұрын

@@PabloGnesutta Yeah, true a lot of ATX ps in the market are not properly made. specially the Chinese ones, i recommend to go for a HP one. Yeah using a motor drive will also solve your issue to certain extend. L293D shield is best option for that. I have used it and works pretty perfect. No. use filter capacitors individually per servo, it's more effective than a one big capacitor hook up to the main supply. I made a SCARA type robotic arm using servos and I fixed capacitors individually to get more smooth and precise movements along it's arms. (that's a 4 degree of freedom arm with 3 servos and one big encodered DC motor) Thank you

@PabloGnesutta 5 жыл бұрын

@@LahisTechLT Thank you for your response. I yet have to try the effect of individual capacitors on each servo, and I will this weak. I solved the problem, after reading a lot, connecting the Power Supply's output to a 7805 voltage regulator with two capacitors and then connecting the regulator's output to the breadboard, it works like a charm now. Thank you for your attention and willingness to answer =) If anyone tries to implement the voltage regulator solution to this, have in mind that the regulator's output could fluctuate if it has no load connected to it. You can test it putting a simple resistor closing the circuit.
