In the past 20 years I worked on a huge set of projects.
Here the one I think are useful

Z80 Retro Computing with Arduino

The ZilogZ80 CPU is an 8-bit based microprocessor. It was introduced by Zilog in 1976 as the startup company’s first product. The Z80 was conceived by Federico Faggin in late 1974. The Z80 was software compatible (!) with the Intel 8080 machine language. It added several extensions and was the heart of the ZX Spectrum. Zilog Z80 is the chip who powered half of the ’80 microcomputers. …

IoT Async

Qualche mese fa avevo sviluppato una applicazione IoT per misurare la temperatura e spedire i dati ad una coda mqtt. Poi c’era uns server che colelzzionava i dati. Totale: tre server, con tre punti di fallimento ma architettura molto “cool” In effetti però la potenza dei moderni chip embedded è tale che è possibile implementare …

Esp8266 Music Machine

After months of esp8266 experimentation, I “just” discovered this little chip has also a I2S Audio digital interface. To discover it you must install the Arduino IDE adapter and code directly in C++ (brr, ok not a breeze but not boring like Java :) I2S is a digital protocol to send your digital  music to …
