Acoustic impulse marker

Adam Wrobel and Michael Grisanti of Cornell University built this device that tracks sound impluses: The core of our system is hardware based analog circuit, which filters, amplifies, and processes the sounds obtained from the microphones. By utilizing hardware for this, we are able to high frequency signal processing without taxing the microcontroller. Also, we remove […]

SARduino 644/1284 board free PCB build

Slack built the SARduino 644/1284 board by Andrew Schamp he got from our free PCB drawer. It’s an prototyping board with support circuitry for Arduino compatible ATmega AVRs. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the […]

QUUB: tiny computing stackable dev board

GRAYnomad (Rob Gray) describes the QUUB as follows: QUUB is a Small Form Factor processor and co-processor design like this ATMega1284-AU based core processor board (above). The basic system topology is that of a “core” processor and up to 16 addressable daughter boards known as “stackables”. Stackables can be smart (with co-processors) or dumb (just […]
