Tim Lukasik made an awesome LED top hat.

The hat was made to wear to Above & Beyond’s Common Ground tour.  Tim used 722 neopixels glued onto a thin foam backing which was then attached to a top hat.  A Teensy 3.2 and a battery pack for power were wired into it.  He programmed the LEDs to display 13 different designs featuring the band’s iconic event logos that rotate in order.

The code for the project has been published on GitHub.

Benni (Tinker-Fun) made custom USB shortcut button to use with your favorite software.

In his work, Bennie uses drawing software and was wanting the functionality to quickly activate the full screen and do things such as rotate the drawing sheet.  After looking at a few commercially available devices, he decided to make his own custom USB device that he could program with the specific functions he wanted.

The device has a single click, double click, turn left, and turn right functionality.  The configurations include:

Double Click: Fullscreen
Turn left: Rotate sheet left
Turn right: Rotate Sheet right
Normal click: The LED ring start to blink and you have now new features:
Turn left: Undo last step
Turn right: Redo last step
Normal click: Back to normal Setting

You can find some additional information about the project on his web page.

Code for the project can be found on GitHub.

Liana B made a fashionable LED scarf.

As Liana says, wearables are not just for raves anymore; they’re a practical solution to being seen at night as well as a fashion statement to wear at parties an events.   On her Instructables page, she offers a pretty good tutorial on making your own light up scarf.

Example code for the project is available on GitHub.

 

Paul took the Monolith Synth to Teardown, a hardware conference hosted by Crowd Supply.

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.

The code for the project is GitHub – LED Visualization and the Monolith Synth.

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.

You can read more about the project on wb8nbs’s blog.  A zip archive of the code for the project as well as a schematic can be found here.

Sebastian Tomczak made a simple, but cool drum machine using a Teensy-LC.

Code for the project is available here.

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.

His build inspired Sirrom0206 to build an LED graduation cap for a friend’s son.  He posted a video about the build here.
