“Using an old VFD serial communication display for use with Arduino based microcontrollers. Story I remember back in 2018 that I got this screen (from an old guitar pedalboard) and didn’t know how to make it work. I was …
“If you’re anything like me, you find yourself changing the volume on your computer quite often. Some videos are louder than others, sometimes you want the volume muted on your computer while you listen to podcasts or music, and …
“I’ve dabbled in wiring together my own little electrical projects over the years, mostly in the form of paperclips, aluminum foil, and cardboard cobbled together with hot glue. I recently bought a 3D printer (the Creality Ender 3) and …
“As previously reported, I’m on a slow track research project into randomness. Having explored the concept of random bits and built some experimental random electronics, I’m still progressing in my question to understand how randomness can be exploited …
“A board-controlled temp probe and fan to maintain temperature during a long smoke or BBQ I’d like to make my own version of something like the CyberQ (https://www.bbqguru.com/storenav?CategoryId=1&ProductId=35). There are many …
“The usual approach to radiation detection is the use of a Geiger-Müller tube and its high voltage circuit requirements, but during a quick surf through the internet today, I came across this portable and “accurate looking” solution developed by Stefan …
“In this tutorial we show how to build a cough detection system for the Arduino Nano BLE Sense using TinyML and Edge Impulse. There is a huge need for inexpensive, easily deployable solutions for COVID-19 and other flu related …
“A cost-effective and open source system to data log health measurements in Google sheets and allows the doctor to monitor them from anywhere Coronavirus disease, also known as COVID-19, is an infectious disease which spreads between humans. The incubation …
“One of the things which makes embedded programming so interesting is that you are constantly dealing with restricted resources. Playing video files is quite resource heavy. Let’s see how ESP32 can handle this. If you have short attention span …
“cVert is the result of an idea I’ve been kicking around for years, and took a few months of work to bring to fruition. The idea was to use a Geiger counter as a true random number generator to …
