Not happy with showing the same Monolith Synth at another event, Paul decided to marry the audio library and OCTO library together to experiment with alpha blending and create LED visualization as the Monolith is being played.
This compact signal generator is packed into a tin that’s just slightly bigger than the ones those curiously strong mints come it. It uses a breakout board with Si5351 and a TCXO from Etherkit.com. A TCXO (Temperature Compensated Crystal Oscillator) allows for very accurate frequency. The unit brings out all three signal outputs, individually programmable for frequency (500 Khz to 160 Mhz), sweep width and limited level control. There is a Teensy LC for control using Si5351 libraries from Jason Milldrum NT7S. The battery and charger are out of a cheap cell phone booster.
Inspired by a chairoplane model he already owned that only worked on bright summer days, Michael made this improved version that works even in winter. He did this by creating a circuit where two solar cells charge 2 5F, 3V super capacitors.
Using a 32×32 neopixel display, a Teensy 3.2, and a bluetooth module, he was able to make the display programable via a smart phone. He has an additional video showing the code for the project as well as a link to a Google drive with the code.
