Micro Python on ESP32 (HUZZAH32)

Adafruit’s HUZZAH32 Feather board is built with the official WROOM32 module: Two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz 448 kB of ROM for booting and core functions. 520 kB of on-chip SRAM for data and instructions. 8 kB of SRAM in RTC, […]

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 […]
