Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there’s just one processor stepping through them. Same for spi, or i2c, or uart. There’s really only ever one sensor reporting back its data at a...
I’ve recently bought a used computer, and it has a few problems. I’m looking for a guide to help me identify which parts are causing the problem....
Hello altogether, I guess everybody has some USB-C cables lying around, but wonder if it’s 3A, 5A, 3.0, TB… Anybody able to recomment a device able to determine that? Maybe also something that can be combined with a load tester.
I got these TP4056 modules from an AliExpress vendor and fail to understand how the protection circuit works or if it’s just typical Ali shovelware. It could be my limited understanding of electronics....
It’s an SPST-NO micro switch. Don’t waste time searching for it. I already wasted mine. Just let me know what it is if you know it off the top of your head. 😊
Since MOSFETs have a gate capacitance you’d want to limit the inrush of current from the output of a microcontroller to prevent it from getting damaged prematurely. That’s what gate resistors are usually good for....
I recently came to the realization that I’ve been kinda punishing myself with cheap no-name solder that is really difficult to work with....
I’m an EE by trade focusing on embedded devices, but most of my work is in relatively low-power STM32 applications. When I stopped following developments in hobby kits, it was mostly Arduino Unos slowly driving I2C OLED displays....
Trying to repair a Hyperkin Duke Xbox controller where the left trigger doesn’t respond. Found that the resistance of this potentiometer doesn’t change when it’s moved, so I’m looking to replace it. I’m a novice with this stuff though and I’m having trouble identifying it. Any help is appreciated.

I’m learning about electronic components. I believe this is the part which has broken and made this heating pad unsafe to use. Well, unusable, not just unsafe lol.
I’m planning to make a modular synth from scratch, but I need to start with the PSU. Do you see any issues with this schematic?...

I want to replace one half of this with longer wire, but I am not confident about the name of the connector used....
So, there are these great 32700 LiFePO4 batteries that showed up in my local industrial market. For like USD 2$!...

Just exploring about this tp-link XN020-G3v router. I’m mostly interested in connecting to the UART, won’t be tinkering with electronics of it, but out of curiosity I tried to search what these chips are. and I couldn’t find much about the big chip. Can anyone describe the 4 main chips on it ? Best would be datasheet, but...
I migrated here in the US (specifically in San Bernardino, CA). Quick Intro: I’m a graduate electrical engineer; honestly, I really don’t have that much experience and not even a decent internship experience due to covid, resulting in an online OJT. Do you think doing an internship here in the US is the way to go? If yes,...
hi again, since i had a bad idea in my last post i wanted to try again to get some feedback i could understand and apply....
My Google-fu has completely failed me. I’ve got an RGB addressable led curtain. It has 20 strings of 20 LEDs in a square arrangement. I initially assumed it had a wire feeding led data back up, to go to the next drop. On checking however, they are T jointed....
To all the electronic nerds out there: I am trying to trigger a 555 timer by movement in a random direction that also occurs randomly and any change in position should trigger the 555. AFAIK tilt switches are not useable here. Does this idea make sense?...
Im building a flashlight and i want to test if a fan in it would be a good idea but the flashlight is really small so i would need a motor thats smaller than 1 cm preferably. I found really good ones at maxon group but unless you order them in bulk(1000+ units) they cost like 400€. So do yall know anywhere i could find them?...
