Vasily Ivanenko has written up documentation on his 7 MHz synthesizer project: Above — All 4 boards were built in re-purposed Hammond boxes. A PIC-based counter sits on top of the offset mixer. I build modular gear and this allows modification and fosters experimentation. When I build a final transistor radio receiver, I plan to […]

The microTS – Smallest synth in the world
MicroTS, a smallest synth in the world from DIY synthesizer: The micro-TS is a key fob sized DIY synthesizer (61x41mm) with actually useable knobs like an analog synthesizer. The ball pen is for size reference. It has a one octave touch keyboard, 6 knobs and a stereo headphone output. Running on a CR2032 button cell battery […]
VXO – based PLL frequency synthesizer for 7 MHz
Vasily Ivanenko made a VXO-based synthesizer: To make a VXO to mix with a ~7 MHz VCO, you’ll need a crystal that is higher in frequency than the highest frequency you want to synthesize. Some rummaging revealed a bag of 21.4773 MHz crystals that I could divide by 3 to garner 7.159 MHz. To afford a […]
Radionova 1 frequency synthesizer
Vasily Ivanenko has written up documentation on his Radionova 1 frequency synthesizer project: Frequency synthesizer for my Jupiter receiver — Радионова 1 — [ Radionova 1 ] Greetings! Most of my future homebrew radio projects will focus on building radio astronomy gear. Radio astronomy offers much fun + learning for the radio homebuilder — example topics include […]
