Hello guys!
I found this board with 25W + 25W audio output and I found that this thing has a switch controller for music and volume. But I couldn't find how to solder them. Is there anyone who used this board? Could you please help me with a diagram?
Hi guys, I’m working on repairing some electrical issues on my old car.
The gauges are a bit wonky, some don’t work and on the special occasion that they do they bounce up and down.
I am currently going through the wiring of the car, but one issue I (may) have found is the check control box...

Hey guys,
This is my first post and I am happy to have found this website. I am currently working on a project using a PCB and jumper wires to make a 48v Phantom Power supply to be used with multiple condenser microphones. To make a long story short, I found a "mostly" detailed post on another...
My ViewSonic VX2250wm-LED stopped working. It blinks white (and then black) when plugged in, regardless of which type of which input plug I use. I know the monitor is the problem because my other monitor, which is the same make & model, works perfectly fine with the same inputs (knock on wood)...
