Channel3 is an experimental ESP8266 project that generates analog television signals directly from a microcontroller GPIO pin. It uses the ESP8266 I2S peripheral at an 80 MHz bit rate and DMA buffers to synthesize radio-frequency waveforms. An antenna connected to the output can transmit a signal receivable by an analog television tuned to Channel 3. The implementation produces luma and color information through carefully constructed one-bit modulation patterns.

AnyPixel.js is an open-source software and hardware library that makes it possible to use the web to create big, unusual, interactive displays. Anyone can fork the code and the schematics to create their own display at any scale. The first display using this platform is in the 8th Avenue lobby at the Google NYC office. To create this installation, we used 5880 off-the-shelf arcade buttons with LEDs inside them as our pixels. AnyPixel.js’ straightforward hardware/software framework makes it...

Linux based client software and a set of AVR microcontroller devices that support the SportIdent electronic punching system used in orienteering. Clients send card data to a PHP/SQL web application, that serves as full featured event software.
