Michael Niles developed and made the Beacon notification system.
Beacon is a hardware device and computer software built for the sole purpose of notifying one or more persons of user-defined events. It can be used for anything that can execute a command line application when something happens such as email clients, software monitoring, and task scheduling. The device utilizes similar methods to cell phones for notification (sounds, flashing lights, and vibration). Beacon connects to a computer via USB
Kris Kasprzak built a microphone monitor to set audio levels during video recording on a DSLR camera.
This DIY project displays the spectrum or a microphone input for 32 bands. Includes a line in for powered microphones, a line out for connection to a camera, and an audio jack to monitor the audio with headphones. Through the touch screen display you can adjust the audio levels as well as display settings. All the settings are saved so that when you turn the unit back on, the settings will come back just as you last had them.
Mads Christensen designed and made What are You Blinking about, a light art installation first shown at Create:Fixate Los Angeles
Each of the three 40″x40″ panels contain 900 WS2812B LEDs driven by a Teensy 3. The Teensys stay in sync with each other using a serial connection. The red/blue light sequences are generated algorithmically at up to 100 frames per second, creating subtle moire and interference patterns on the viewer’s retinas due to the interplay between rods and cones in the human eye.
This project creates the high voltage signals a Western Electric 1D/2D Payphone requires to manage calls, accept coins, etc. These signals include both +130VDC (coin collect) and -130VDC (coin refund) as well as +25VDC for the “stuck coin” test and -25VDC for the “initial rate” test. It can also count dial pulses to provide out-of-band signalling to Asterisk for the rotary-style 1D1 payphones.
Additional details on the project, including the code, can be found on this GitHub page.
zike, a fan of antique oscilloscopes , used a Teensy 3.5 and a couple of probes to draw vector fonts on the display of an old analog oscilloscope.
The project was inspired by this vector display introduction by Trammel Hudson of NYCResistor using a Teensy 2.0 and an R-2R ladder DAC built with 32 resistors (16 per channel) . This project makes use of the Teensy 3.5’s built-in DAC with no additional parts. The fonts are Hershey vector fonts, originally designed to be rendered on early CRT displays.
Natthakit Kim Kang designed and built and incredible interactive LED installation, Click Canvas.
The project was developed to display at Yolo House, a creative space and gallery in Bangkok. The installation features 187 LED boxes in a 17 x 11 grid that change colors when users press them. It uses a Teensy 3.6 to control 2,244 LEDs.
Be sure to check out the project write up over on Hackster.io. Kim has a great write on the process of developing and installing the project.
Fashion tech designer Rachel Freire designed Jump North, a custom jumpsuit that senses where the direction north is.
The project was a commission as part of her residency at KOBA, an electronic textile tailor shop on Germany. Rachel decided she wanted a version of the “Northbelt” built in to her jumpsuit that would allow her to always sense where north is. Jumping triggers the north-mode on and off. When you sit still for too long the belt will start to “purr”, waking you up, encouraging you to move as a travel companion might, or relaxing you as it causes you to focus on the sensation.
