As you might guess from this video, the hack is written up in Spanish, but it’s nothing your favorite translator can’t handle if … Read the rest
Up next on the continual march of expansion boards for the Raspberry Pi is the Raspy Juice, a board designed to break out the GPIO pins on the Raspberry Pi into servo, serial, and other miscellaneous connections.
The Raspy Juice features an ATMega168A microcontroller connected to the Raspberry Pi as an I2C slave device. Not only does the addition … Read the rest
