Fancy a 6-voice virtual analog synthesiser DIY project starting at just over $20 for the microcontroller? This Nucleo Synth project should appeal.
Not everyone can afford a much desired Moog analog synthesizer. For those that would like that analog experience and are prepared to go the DIY route, the parts can often set back a maker many hundreds of dollars or pounds. Which is why this new project from pappas.chris caught our budget conscious eye. Imagine being able to create a 6-voice virtual analog hardware synthesizer starting at just $23 for the microcontroller board of the Nucleo Synth.
The STM32F7 microcontroller is at the center of this 6-voice virtual analog synthesizer. All you need on the hardware side if the STM32F7 Nucleo-144 board, one stereo audio jack, and a USB-OTG to USB-A adapter.
This synthesizer should be fairly straightforward to program too.

Here's a demo of the synth in action from the creator of Nucleo:
