Hello everyone! I’m designing a PCB and I have some doubts about how to connect the 4 resistors at the top to capacitor C34. They are 4 traces, and all of them terminate at the same pad of the capacitor. As I have currently placed them, are they connected correctly? Or should I connect them in a different way?
First of all, I apologize for the lack of a “formal” schematic… I tried to draw one out, but got buried in the nuances of it :)...
I bought a PWM Dimmer based on a 555 from AliExpress to regulate the brightness of a 12V 1A 1 meter LED strip, I already built one myself years ago on a perfboard but this one was the exact dimensions I needed for a project. I built mine from components from AliExpress and components found in old electronics so I thought nothing...
Since I never understood op-amps from reading or practicing problems I wanted to build a circuit to probe around and use different resistor values to set the amplification....
What I've done is take a large 2n3055 BJT NPN power transistor, and decap it (it is a large metal-can type). Then I carefully removed any coating from the exposed silicon (it typically has a dab of silicone potting compound on it)....
I bought a random cheap crystal oscillator off AliX. It was advertised as a “constant temperature crystal reference”....
Bought it a long time ago and can't remember. There's a jumper cable and I remembered using it to flash something. I only dabble with Atmega32U4, Atmega328p and stm32 blue pill, so it's probably either of them....
Hello,...
Looking to replace the male connector in this picture. Any idea what it is called and where I can get it? I'm in Germany.
I have a acer c740 chromebook that has a cracked charging jack hoping I can find replacement part for it. Picture attached shows what's left of some number on it I think it's 150726+F4 not sure what the symbol is. The male end end is 3mm od 1.1mm Id if that helps.
I'm working on adding extra access control to elevator calling buttons and i would like to identify the connector type of the wires connecting elevator buttons to the elevator panel...
