This project is about to DIY an Arduino board wth an ATMEGA644P or 1284P to have more INPUTS/OUTPUTS than on the atmega328P. You can buy an arduino mega but it’s more expensive. The microcontrollers will be bootloaded with Sanguino and the project seems to be like another one called CALUNIUM. On this clone you will […]

With Google announcing the launch of Voice Search for desktop, we couldn’t help thinking that there was even more fun to be had with talking to a computer. So, we went ahead and built an open source dev board to inspire people to build their own useful and wacky contraptions to take Voice Search to another

I love the Arduino as a simple and accessible controller platform for many varied projects. A few months ago, a purchased an Ethernet shield for my Arduino controller to work on some projects with a mate of mine – it was a massive hit – for the first time, I could control my projects remotely using simple
MMC/SD/SDHC card library This project provides a general purpose library which implements read and write support for MMC, SD and SDHC memory cards. It includes low-level MMC, SD and SDHC read/write routines partition table support a simple FAT16/FAT32 read/write implementation The circuit The circuit which was mainly used during development consists of an Atmel AVR
