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