Linear Technology’s LTC2631A-LZ8 is an 8bit digital to analog converter (DAC) with an I2C interface. This DAC can output 255 different voltages, spaced evenly between 0 and 2.5volts. We previously demonstrated the LTC2640 with a three-wire SPI interface, but this version is controlled with only two signal wires.

Bug Labs makes hardware modules that can be combined to create your own custom gadgets. They’ve just released what we consider the most useful module: BUGvonHippel. Unlike the previous single purpose modules, the BUGvoHippel is a universal interface. The bus features USB, power/ground, DAC/ADC, I2C, GPIO, SPI, serial, and more. BUG applications are written in Java using a custom IDE.
The $79 module is named after MIT professor Eric von Hippel, who wrote Democratizing Innovation. You can find an interview with him below.
