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.
gltovar was looking for a physcial project to build after focusing of software for a while, so he made a custom Starcraft keyboard.
After going through some tutorials on keyboard wiring, soldering, and PCB design he settled on on a physical keyboard and hacked it to make each column of keys adjustable.
Code for the project is available on Git Hub.
wb8nbs created an Si5351 powered signal generator.
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.
Michael Diesing (forum user Joegi) built a solar powered chairoplane model.
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.
Freeside, a hackersapce in Atlanta, built a 10-foot tall infinity mirror.
They did a great job documenting the build in this video.
This impressive build features a 7 x 4 ft infinity mirror mounted in a 10 ft tall archway. They used WS2812 addressable LEDs driven by a Teensy to create the infinity effect.
Barkus Labs made a cool LED graduation hat.
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.
