After previously fixing an overly bright picture from a Voodoo graphics card with a simple resistor on one of the RAMDAC’s ...

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, ...

Ever wanted to track your bike, car, or even monitor your loved one's location in real-time? Building your own Arduino GPS tracker gives you complete control over your tracking data without expensive ...

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 ...

In this guide, we’ll explain how to set up a private LoRaWAN network using the Raspberry Pi CM4-based RAKwireless’ WisGate Connect gateway and Docker or Portainer to install NodeRED, InfluxDB, Grafana ...

In the past few decades, aquatic animals have become popular model organisms in biology, spurring a growing need for establishing aquatic facilities. Zebrafish are widely studied and relatively easy ...

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 ...
