PiPurr remote cat interaction server

When the cats away, the mice will play. But…. what’s the cat doing when YOU’RE away? That question led Tris of CantHack, a group of geeks from Canterbury, UK, to develop PiPurr. Tris explains, “PiPurr is a simple client-server solution. The server runs on a Raspberry Pi, for low power consumption and provides the functionality […]

Project Fleatiny 8051-based board

Valentin Angelovski has developed Project Fleatiny, a 8051-based hobby board. “Project Fleatiny is a 100% open-source hobby-computer built around the 8051 micro controller. From a software point of view, Fleatiny consists of a sofware kernel (taking up from ~3K to 9K Program ROM area depending on installed kernel option modules) that essentially turns any fast […]

Parallax Propeller discriminates Walsh-modulated IREDs

Parallax Propeller guru Phil Pilgrim has posted this IR sensor/discriminator project on the Parallax Propeller forums. “Almost everyone here is aware of the advantages of modulated IREDs for rejection of background IR fluctuations and line-frequency noise from artificial lighting. Typically, the IRED modulation occurs at 38 kHz, to which the integrated detectors are tuned and […]

Arduino guitar mod lets you type with a tune

David Neevel of W&K Blog had been thinking about modding a guitar to use as a keyboard for some time. As shown in this video, he recently got down to business, interfacing the MIDI output through an optoisolator circuit to the Arduino. The interpretation of notes to keyboard characters is accomplished in code, with the […]

Bartendro serves up cocktails using open source

Bartendro is a robotic cocktail dispensing machine controlled by a Raspberry Pi. Dispensing of drink components is via peristaltic pumps which dispense a known volume with every revolution of the motor to precisely meter drinks. The Party Robotics developers explain, “Each pump combined with our custom electronics is called a “dispenser.” The dispenser boards use […]

Car cassette player converted for MP3 play

Ivan Creations wanted to use his old car cassette player (that sounds descent) to somehow play MP3 files. He devised this hack using PIC16F877A to control CECL08D MP3 player and Grundig WKC 1704 RDS Infomat Cassette player with remote control via Blaupunkt RC10 remote. “The MP3 player output signal is hooked up to the cassette […]

Door security logger with A13-OLinuXino-WIFI + OpenCV

Tsvetan and his crew at Olimex designed this simple project with A13-OLinuXino and OpenCV. “Now everytime somebody enter our lab A13-OLinuXino takes picture with timestamp and store on the SD-card, later we can view the captured images via the web on OLinuXino IP address.” The project sources are on GitHub. Via the contact form.
