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.
This carbon-fiber armor has an LED underbelly. It uses NeoPixel LED strips to run light animations. The armor pieces can be made to mix and match. All pieces hook up to a battery back and micro-controller – both of which Alex made some 3-D printed holders to wear on a belt.
The LEDs are mounted so they face towards the skin to create an under-lit effect.
Code for the project, as well as the plans for the 3-D printed utility pockets, can be found on Hackster.IO Project page.
LeoneLabs created PixelBrite, a study in pixels. This amazing build is more than a light table. It’s a digital Lite-Brite, minimalist light sculpture, a disco light, a sound reactive light show all rolled into one.
With batteries and a slot for and SD card to stream patterns without a computer, PixelBrite can act as a standalone light. You can also plug it into a MIDI controller and have a interactive light show.
The Instructible page on the project is well worth reading. It’s incredibly detailed and contains not only build details (like a complete bill of materials spreadsheet) but some information on color theory and display science as well.
