GPS-Disciplined Oscillator by Alan Cashin. This GPS-Disciplined Oscillator is mostly built in software, so it only requires a PIC, an oven-conditioned crystal oscillator and a few other supporting parts. It provides an extremely accurate 10MHz signal with an error in the parts per billion range.
Dual RF Amplifier by Charles Kosina. This small RF amplifier has two outputs with individually selectable gains. This makes it suitable to add to a signal generator to provide a higher output level, or for better drive strength, or fanning it out’ to multiple other pieces of equipment and more.
UVM-30A Module Ultraviolet Light Sensor by Jim Rowe. This UV light-sensing ‘breakout’ module detects the intensity of UV solar radiation and hence the degree of protection you may need to prevent skin damage. If you connect it to an Arduino or other microcontroller, it can even indicate the current ‘UV Index’.
Songbird by Andrew Woodfield. Here’s a decades-old design brought up to date in a new package and made to appeal to beginners as well as experienced builders. It’s quick and easy to build and a great project if you’re new to electronics.
