I am curious if one, something like this exists, and two what the cost might be? I am looking for a screen, I assume an e-ink is the best/cheapest option and I want it to be as close as possible to the size of a playing card, ideally not thicker than 2MM. But I think up to 5mm could work....
Disclaimer: this is not specifically for a commercial product, but various things I design sometimes get commercialized. I mention this so that you may decide whether you want to weigh in. If it’s commercialized, I will probably make very little money but a bunch of university students may get a neat STEM program in the...
Some years ago, before LEDs were a thing, I bought an Ultrafire WF-500 Flashlight that features a Xeon light bulb. As you might imagine the bulb reached its lifetime and burned away....
Hi all, I have a water pump connected to an adapter (pictured) but I am having trouble getting it to run using any of the cords I had on hand; it calls for using DC-only & 12V (between 9-14). I have tried Googling around & browsing Amazon but I’m a bit overwhelmed with options. Can anyone suggest an adapter that’ll get this...
I am powering a 5V microcontroller (arduino clone, atmega328p) using a 9V block and a buck converter. Now I want to let the microcontroller occasionally measure the battery voltage, so I can get an idea of how full it is....
Is there a way to figure out my LED board and fix it myself? I got this LED light which works perfectly but the issue is the usb charger port on the left is not working for whatever reason. There are two ports one micro for charging the led and one usb for outlet charging. Is there a way to switch the charging to the usb port?...
I am making a graphics card on the tang nano 20k board. I tried synthesising the design in the official IDE and it output:...

Hello! What would be a good way to learn about electronics in terms of creating them? I’m particularly interested in building my own keyboards and other PC peripherals, but I’m not sure what tools I would need, or what’s a good knowledge base if I run into any issues. Any tips and or suggestions?
In a transformer, why are both coils apart from each other? Wouldn’t make more sense to have the ferrite core (tube shape), wind the primary coil around that and then wind the secondary coil on top of the primary? So that the magnetic fields are as close to each other as possible?

Serious question from a beginner in electronics. For reasons I do not fully understand, I have become fixated on the idea of collecting small amounts of electricity from “interesting” sources. I don’t mean “free energy”, instead, I mean things like extracting a few mV from being so close to a AM radio tower using two...
My wife gifted me this super cute mini miffy diorama from a gachapon. It uses two 1,5V cells and has a tiny led in it. I would really love to to add a 24h timer. ( it should stay on for 4 hours after turning it on then go to “standby” for 20h before turning back on) Do you guys think an attiny85 is the right thing for the...

Hi everyone! Recently I have gotten interested in communication protocols and have been looking for one (with little success, hence my question) which would satisfy the following requirements (in prioritized order):...
I just came across this and thought I’d share. I’ve struggled to get headers and IC’s off boards after soldering them on backwards/upside down. This video shows a cool trick with a piece of copper wire that makes them very easy and quick to get off without expensive tooling. I was thoroughly impressed. Hope someone else...
I purchased an e-bike which was advertised as just needing the batteries replaced. The li-ion batteries had been sitting dead for months. Once I got the battery removed it was clear that was not the case. You can see the hole where the plastic melted from this component overheating on the board. The burnt one is the same as...
I replaced my laptop’s battery after it was swollen. I found out that services like call2recycle do not take swollen batteries since they are potentially hazardous material. How can I get rid of that damned spicy pillow? In Dallas. Thanks....
Hey all, have I damaged this xbox 360 controller circuit board beyond repair?...
Hey everyone,...
I’m trying to use an LIS2MDL ic with an Arduino nano on a custom PCB designed in KiCad. I tried the Arduino example compass script for the ic and it didn’t work. It just prints “Magnetometer Test” and nothing else happens
