Learn how to repurpose your spare ESP32 boards into cost-effective presence detection sensors using the Tommy Sense ...

As my projects became increasingly complex (and required more discrete components), I decided to migrate several of them from "discrete" electronics to microcontrollers. During this transition, I ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

This blog post is part of a series on physical tools for science with THING Tank project. It follows the author’s participation in the Creative Commons Certificate for Librarians course to learn more ...

Combining 3 Arduino boards to create a GPS tracker & data logger. I had an idea to combine the new Arduino Nano 33 BLE Sense with an SD card and GPS module for a side project that logs GPS and IMU ...

Last month, I received Qoitech Otii Arc power supply, power meter, and DAQ unit that aims at helping hardware and software engineers develop energy-efficient products. I’ve now had time to test the ...

This is a mini-NTP based on a ESP32. Time will be provided from the GPS receiver and a DS3231 if no GPS-signal is avaliable, to server time to your networkcleints. With the feedback and help from our ...

The cheap MP3 VS1053 codec processor that has come from aliexpress.com is told to be capable of decoding a variety of music formats, including Ogg Vorbis/MP3/AAC/WMA/MIDI audio, was lying on the table ...
