Hi ! I'd like to build a 150W stabilized variable power supply (0-30V 5A) like the ones you can find on the market. But surprisingly I haven't really found a ready-made schematic, as if there was no consensus. I've understood that there are 2 types of power supply, linear with a large...

Hey! starting my journy on Arduinio.When i tried to connect my joystick, and read the values from it,I gaet the whole range on X. My problem is with Y: Resting pposition indicates 0, and if i move the joystick down it shows the value 512. if I move it upwards, the value does not change. where...

i made a hand made transformer and wanted to ask the forum how and with what should I power it. And will it even work.

Hello, Please may someone provide a little more explanation with regards to how the value of g affects an accelerometer's performance? My knowledge is limited in this field and I would like to know the following for generic accelerometer. For arguments sake I have chosen an Analog Devices...

I know its a bit janky but Ive just needed to make this door opener device remote control and for some reason, I cannot get this receiver to power anything even when both channels are on. Can someone help me?

Helloo we have trouble replicating this circuit, from what I read before its missing a diode for C4 to discharge its signal, although I'm not sure what kind and where to place it

Hi, i have been trying to o a all transistor binary counter using d latches but my pcb doesn't work. When i test it on simulation program everything is all right. Can you help me see where i have made a mistake?

hi everyone, I am trying to repair my drone controller. One of the component is broken and fell. I think its a crystal oscillator. Its 6mm x 1.5mm. I dont know how much mhz it is. Is there a way to know how much it is at home. I wil attach some images of it and where it belong. Even if you guess...

Hello people!! This is my first post so I don't know what im doing. First off I'm relatively a noob with this stuff so if I'm doing something wrong that's why. I plan on making a very modular ALU using only discrete logic and home made pcb's using my SLA printer. I'm very early in my design so...

Hi folks I am trying to build a circuit which will govern the speed of the fans in my solar cabinet based off the temperature inside. https://www.circuits-diy.com/temperature-controlled-fan-using-555/ I built this circuit hoping it would work with 6x 24v / 0.08A PC fans (40mm) I have 3 of...

Hey guys, I am relatively new to micro electronics, and am in desperate need of help! I want to bypass the muting circuit in a electronic piano. This involves either activating the relay, or pulling it to ground (BA3-5 Relay, and the highlighted LS1 in the picture below). Please could someone...

Hello everyone, I have next to no knowledge of electrical eng or circuitry and am having some trouble with my homebuilt arcade. The essence of my problem is that I want to wire both the computer and monitor to the same rocker switch. The monitor turns on via a button press that completes a...
