All About Circuits have a fun start to a hopefully new series on DIY Synths; here’s a bit from part 1:
Music used to be done entirely with REAL instruments such as guitars and pianos but what about synthetic sounds? Well, a great band to look at for an example is Kraftwerk which in the early days (1970s) used synthesizers to create all their sounds from the aggressive sawtooths to the gentle beep and boop of a computer. These synthesizers (unlike most ones you will find today) where all analogue which means that instead of relying on software and processors the sound generation was done by manipulating electrical signals against time.
But how does an old fashion synthesizer work? In this project we will be building the heart of the synthesizer, the VCO which takes in analogue voltages and generates the raw sounds ready to be further processed by filters, modulators, ADRS modules and step sequences.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
