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
Monitor and switch up to eight sets of points (“railroad switches”) from a single Controller. We also show you how to make LED-based signals to go with each set of points. by Les Kerr
This simple device for the home or office will automatically restart your modem or router if it stops working. It can’t stop your internet connection from dropping out, but it will save you the hassle of pulling the power to see if it’s the router at fault (which is often the case, unfortunately). by Nicholas Vinen
When updating our SMD Test Tweezers we found out the micro used in it wasn’t in stock, so we had to pivot to using the newer PIC16F15214. So what does it offer over the previous 8-bit micro we were using? by Tim Blythman
This compact Speaker Protector works with up to six amplifier modules and can operate from the same supply (up to ±40V DC). It perfectly suits the Hummingbird Amplifier module described last month. by Phil Prosser
