Emotion Lamp

The idea behind the Vocal-Emotion Lamp is rather simple: to use a small affordable computer that can continually recognize emotion from the human voice and then visualize the result of the analysis, effortlessly and enjoyably. The implementation of this idea uses the small and inexpensive Raspberry Pi computer, extended with a far-field microphone expansion board. The software that performs […]

Extended list of 8-bit AVR Micro-Controllers, easily programmable with the Arduino IDE

A couple days back, I wrote about ‘The $3 Arduino‘, how to leave the Arduino board behind and program an ATmega168 Micro-Controller directly, still using the Arduino IDE but with the AVRMSPII programmer. Of course, the ATmega168 isn’t the only MC available for something like that. In fact, I have quite a few 8-bit AVR […]

The $3 Arduino

Buying and using an official Arduino Board like the standard Arduino Uno is the perfect way to get started with the Arduino language, common electronic components, or your own embedded prototyping project. However, once you have mastered the initial challenges and have built some projects, the Arduino Board can get in the way. For instance, […]
