Fresh hacks every day
The Artemis Synthesizer was created as a kit for Boston University's Artemis Project. This project aims to teach female rising high school freshmen about computer science with hands-on activities. [Chris] based the kit on a ATMEGA328P microcontroller and a MCP4921 digital to analog converter. It can be used in a keyboard mode, where the buttons toggle various notes of the scale, or in a … [Read more...]
[John] from MIT is working on a project to bring a little bit of interactivity to the hacks he does.

The brunt of the hardware work is taken care of by using an IOIO board which makes it easy to interface any … [Read more...]
This hardware, which was built as a Computer Engineering project by [Bryon] and his classmates, gives you feedback and control of a car though a cellular phone network. It uses text messages to communicate with a control device. This can be pretty much any cellphone, but in the clip after the break they show off an Android app which puts a pretty GUI in front of you and abstracts away the tedium … [Read more...]
