Rudolph thought it would be nice to have one radio transmitter that could talk to all of his creations, so he created rudRemote.
rudRemote uses a NRF24L01+ radio module and a Teensy 3.2 to interface the controls. Almost any type of housing can be used. In this case Rudolph used a 40-year-old transmitter that he found and added an OLED display. The controller uses CRTP (Crazy RealTime Protocol) so he could use it to fly his CrazyFile quadcopter.
Scott Pitkethly (aka unicornpower on the forum & cutlasses on his blog) designed Glitch Delay, a DIY Eurorack module that fits nicely inside a lunchbox.
The effect consists of a standard delay line, or delay buffer, with multiple read heads that each read the audio in a different way. There is a feedback path, so the effected signal can be feedback into its self.
There are 2 types of read head:
Loop heads – These heads loop small sections of audio. There are 3 of these. One that plays the audio an octave lower, one at the original octave, and one an octave higher. The size of each of these loops can be adjusted (size dial), as can the amount the loops move each time the loop starts again (jitter dial)
Reverse head – This head plays the buffer in reverse at the original octave.
The top white button allows you to set a tap tempo. This forces the looping heads to jump to a new position on every beat.
The bottom white button is the ‘freeze’. This freezes the write head. No new audio will be written into the buffer, the old audio will remain. This essentially ‘locks-down’ the audio, so it can be tweaked without the buffer changing.
A bit more information can also be found on his blog.
Code and schematics for the project can be found on GitHub.
The installation features over 3,000 WS2812b LEDs in 16 windows. The LEDs react to an ultrasonic distance sensor (HRXL-MaxSonar-WR) under the pier that is used to measure tides and wave heights. A Teensy 3.2 and a OCTO28 Adapter along with the FastLED Library are used to control the LEDs.
This video shows some of the behind the scenes work.
There is some additional discussion about the project here and here.
Jeff used a Teensy ++ 2.0, ADNS-2051 sensor from an Apple mouse, Seimitus arcade buttons, and a 2 1/4″ amethyst ball to made the project. He has plans to add a joystick to recreate the PantherXL game controller.
Ben Heck of element14 built a portable pinball machine.
In the first video (part 1) Ben discusses the design of the project and puts the electronics together, including writing the code. In the second video (part 2) he finished building the portable pinball machine.
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.
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

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.
