NEW PROTOTYPE: USB & serial LCD backpack

Small character LCDs can show new mail stats, system performance, news feeds, and more. The USB and Serial LCD backpack connects HD44780-compatible character LCD screens to your USB (or serial) port. Almost every open source hardware shop sells some type of serial LCD backpack. Our goal is to build an update to the classic serial […]

Dangerous Prototypes source code visualization

See two years of source code development in a 6 minute visualization. Tayken used a script to visualize code development in the Dangerous Prototypes SVN repository at Google Code. Watch for the 2 big reorganizations, one in 2010 and again in 2011. In the beginning there’s a single long-term contributor, but around 2010 the number […]

Home Camp: Ciseco energy and control wireless serial links

Ciseco energy and control demonstrated several different wireless serial links based on a CC1110 433MHz radio + 8051 processor chip from TI. The modules can be used for serial communication with an Arduino (or any board), and are capable of over-air remote updates using the standard Arduino bootloader. The project is not yet open source, […]

Home Camp: wireless Open Energy Monitor

Trystan and Glyn from the Open Energy Monitor project presented a 100% open source home energy monitoring platform based on the Nanode. Wireless sensors collect data and send it via radio to a RF->ethernet base station. The base station saves the data to a server, either the Open Energy Monitor’s servers or a self-hosted copy. […]

Home Camp: The Nanode

Ken Boak discussed the Nanode Arduino-based network node. The Nanode is an all through-hole network development board, designed specifically as a home monitoring and automation platform. Firmware built in the Arduino IDE using open source libraries reports statistics to Pachube, a website that shows real-time data from small internet devices. The hardware combines an Arduino […]

CoolRunner-II breakout free PCB build

Schazamp has built a free CoolRunner-II breakout board. He had success building a 8bit binary to 3X4bit decade converter which he will use to drive a 7 segment display via the 74hc4511 driver. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send […]
