Basic RF Signal Generator by Charles Kosina. Our AM/FM/DDS Signal Generator design from May 2023 is a great piece of test equipment, but overkill for many tasks. If you only need a basic test signal from 10Hz to 25MHz, then this Generator is just right - compact and cheap to build.
Automated Test Bench by Richard Palmer. This ‘Swiss Army Knife’ provides test voltages/signals, varies a resistance, switches a component in/out of circuit and even measures some voltages. It uses automation software, testing automatically and records input and output values for analysis.
Silicon Chirp by John Clarke. This pet cricket will keep you company; it only needs to be fed occasionally and won’t run away. Keep it for yourself or play a prank on a family member or friend by hiding it in their room. When they switch the lights off, they will get a bit of a surprise!
