Oh and if someone knows how to calculate the cut score pm me the answer.

Basically I am a software developer and I am new to electronics. Consider that a paper have different touch points drawn with a graphite / pencil and I would like to transmit the touch points' codes / values to an android mobile application. And I have an android app which runs a thread with a timer...

25MHz Dual-channel DDS Arbitrary Waveform Function Signal Generator Specs are: Frequency Range Sine Wave Normal Modes: 0.01Hz~25MHz Square Wave 0.01Hz~6MHz Triangle Wave 0.01Hz~6MHz Sawtooth Wave 0.01Hz~6MHz Arbitrary Waveform 0.01Hz~6MHz TTL Digital Signal Wave 0.01Hz~6MHz I'm using it on a old tub...

Hi all new here so please be gentle. I have a Polaroid led tv I'll spare you all the boring details but after some Internet research I found a problematic diode in the TV. Main question is about the numbers on these diodes as I have a few old electronic boards lay about in the shed so replaced that ...

The particular case here is one of those systems where you have a light antenna on the roof, a little box inside controlled by a remote control for rotating clockwise or counterclochwise and the antenna connection and box is through a single coaxial cable. My questions are: 1) is the box sending a d...

Obviously it has a sufficient output to drive ear buds, but just how large a speaker would it drive? I like the idea of extension speakers but find the quality of bluetooth audio garbage so "hard wired" is the preferred option for me and if I can get away without a built in amp that would be great

Hi guys, I do not have a whole lot of knowledge concerning electronics so I am turning to the forums for information. In my circuit I want to control a servo motor. But I only want to power this servo when I am using it. Here comes the transistor in the picture. With a USB supplying 5V to the collec...

I have a 12v led push button switch that I want to function like a regular push button that does not use any power, i.e. No led. I want to use the led, but when pushed I do not want to send power over the load, just close conductivity like a regular push button. So, is there a way to drop the 12v th...

Hi, I'm not the best at understanding electronics, how does a constant current load work and how can i make one, and what makes them have limits before they get fried?

I have a cap on a board that is 405v 47uf 105'c and is 50mm long by 10mm (2" x 3/8").
Can I replace it with a cap of the same value but physically smaller ? Half the size.
It is in a switch mode psu.
