The MicroMag3 measures the strength of a magnetic field in three axes (north-south, east-west and up-down). It can be used as a magnetic compass and inclinometer. by Jim Rowe

This project demonstrates how two modules can be combined with a bit of extra circuitry to do a useful job. The result is a circuit that will power a load, like a fan, when the ambient temperature exceeds a set threshold. by Tim Blythman

IR (infrared) remote controls have been around for about 50 years, with TV being one of the first major applications. They are used in many fields, so components and modules for IR remote control systems are widely available. Here’s how to use them to build an IR remote control extender. by Tim Blythman

We are already using this Mini Project every day. It’s easy to build and requires only a Leonardo board and a display shield. It’s a Symbol Keyboard, allowing you to easily type symbols and other characters that don’t appear on regular keyboards. by Tim Blythman

The Radxa ROCK Model 4C+ is compatible with much of the Raspberry Pi ecosystem and is in the same form factor as the Raspberry Pi Model 4B, but it has some unique features that differentiate it from the Pi. by Tim Blythman

The ESP32-CAM is a WiFi camera module we previously reviewed and have now incorporated into a BackPack design. It includes a powerful processor, so you can use it as the basis for a remote monitoring project or similar. by Tim Blythman

The Altronics Z6387 is a WiFi and Bluetooth-enabled 2MP (two-megapixel) digital camera utilising the ESP32-S3 microcontroller. It can be interfaced with another microcontroller or used as a standalone device. by Tim Blythman

Sim Lim Tower and Sim Lim Square in Singapore are two centres full of shops crammed with all manner of electronic items. I recently had the opportunity to travel and explore both. by Tim Blythman

We take a look at two relay modules based on the ESP-01, one from Jaycar (XC3804) and the other from Altronics (Z6427). Both can be remotely controlled over WiFi. by Tim Blythman

This Multi-Channel Volume Control can handle up to 20 independent channels, allowing you to build your own home theatre or surround system. You can use a touchscreen LCD panel, an IR remote control or an OLED Module with a rotary encoder to control it. This article has all the construction details. by Tim Blythman
