Stiamo lavorando per la finale Nazionale dell'EBEC (European BEST Engineering Competition)... Sarà davvero MOLTO interessante, ci stiamo dando un bel pò da fare!
Per iniziare a stuzzicarvi, pubblichiamo qualche info su di un giocattolino che abbiamo sviluppato in questi giorni:
Si tratta di uno slider che monta un piccolo microcontrollore, un 12F675, che genera segnali servo.

Fireflies in a jar, that's exactly what this project concerns!
instead of the real ones, we used some LEDs that simulate the fireflies behaviour turning on and off in random sequences managed by a microcontroller.

Working on the Autopilot Panel for Boeing 737 project for FSX we needed a driver for mutiple 7 segments displays; the biggest problem with this kind of display is in fact the great expense of I/O ports, and the need for a great number of resistors. You can solve all in one shot (an expensive one) with MAX6955, a common cathode display driver from Maxim that can drive 16 7 segments and works with I2C protocol.
You can find the datasheet here
The datasheet is full of info but, given this chip can drive a LARGE nuber of devices of many many kinds (16 segments, 14 segments, bicolor 7 segments, led packs) a bit of crawling thru tables is required to understand what goes where.

The Autopilot panel for Boeing 737 project needed a good inupt/output expander; we finally choose MCP23018 produced by Microchip, which has an I2C connection (there's also the SPI version, MCP23S18) and two 8 bit registers for input output, configured as open-drain (if you don't know what this means, the chip can only give logical 0 state, while logical state 1 is gained thru pull-up resistors and setting the port to high impedance), and bit-by-bit activated internal pull-ups.

I due giorni di seminario sono stati FAVOLOSI! Un'esperienza unica per scoprire sempre di più sul mondo della musica elettronica e conoscere altri appassionati, condividere esperienze e conoscenze.
Un grazie di cuore a tutti quelli che hanno partecipato!

As you can see many of the pages on the website are still empty and galleries aren't complete; we're working on the website and we have many many things to upload... work in progress!!
