Build an Electronic Load for DC and AC

Build an Electronic Load for DC and AC

Even though an electronic load is not a tool many people will use daily, it is very practical to have one in your lab just in case. Testing a power supply is probably the first thing that comes to mind, but what about that AC heater regulator that isn’t functioning too well? This electronic load can test it as it is suitable for DC as well as AC.

Environmental Monitoring System with ESP32

Many people care about the environment they live in. It's not about the speed of your Internet connection or other mundane problems, but about particulate matter and radioactive elements floating in the air. This Environmental Monitoring System allows you to keep an eye on what is going on around you.

Trying Out the ESP32 Smart Kit Bundle with Arduino and MicroPython

In this video we review the Elektor ESP32 Smart Kit Bundle consisting of the Elektor book "The Complete ESP32 Projects Guide" and the "ESP32 Smart Kit" component box. We learn how to set up the Arduino IDE for the ESP32-DevKitC, and try a few examples with it. In the end we switch to MicroPython and make an LED flash.

Review: Bench-top Power Supply PeakTech PSU 6225A

The sudden death of my faithful lab power supply offered a good opportunity to try out the affordable PeakTech PSU 6225 A which has similar current specifications as my deceased PSU (5 A vs. 6 A). The small form factor of this PSU was also a point in its favour.
