Il collegamento Wireless lo vorrei fare con i moduli NRF24L01 oppure con APC220, cosa ne pensi? comunque ho ordinato gli ESP32 da Amazon per poterli sperimentare.
Sto realizzando il circuito stampato per comandare gli ULN 2803 con gli SN74HC595 per il comando dei led della barca....

I think what you want to do is easier, cheaper and more functional with ESP32. The reason to think so is that in ESP32 have been collected all the functionality of the arduino and the transceiver in one module. You just have to add a periphery. Meaning of the powerful MOSFET`s.

Ciao Evgeni
Hai avuto un'ottima idea di fare il doppio comando,
come pirotecnico cosa usi? e dove li compri?
insieme danno anche i pantaloni?

Hi, Evgeni
You had a great idea to do the double command,
what pyrotechnic do you use? and where do you buy them?
do they also give pants?

Hi Stefano,

As I said in 1983 - 1990 at least in Eastern European countries no pyrotechnic materials were sold. We made them ourselves. Carton shell diameter 8 mm. The device it was such:



But please don't ask me what the special gunpowder is! Without a fight I won't say !!! Now I try with factory ones:
But the result is sad. Their wick is too long and they are thundering very late. I tried to shorten the wicks, but they thunder when they want. I decided to make them myself again. But again, don't ask me for details! The forum is readable by both children and terrorist. Such information is not for public display !!!

I'm trying to find a friend from my competition. His name is Ivo Brezo and he is from Turin. In 1985, he participated on behalf of Italy in the competitions. I think I found it on Facebook but I can't connect with it. There are probably too many invitations for friendship and don't read them all.

I would ask if anyone from this forum can help me with this.
Thanks in advance!

Lately I've been working on a new smoke bomb design. It will imitates a life raft. I did a successful test it today.
