I look for pushbutton to be triggered by drum sticks. I will wire these buttons to GPIO and then use piface or retrogame programs to simulate keyboards input. But i don t know which kind of pushbutton i need; they must be robust of course, but sensible enough. I would like to constrcut a kind of dru...

I 've just found something intersting on the web

Ok, it is less homemade but it is definitely safer

Thanks anyway for your advises, guys

Thanks for your reply. I m a bit confused. Is that so dangerous? A photo triac is just like a switch power, no ? Anyway i need to dig a little bit before trying something, for sure. Thanks Photo triacs are as simple to control as controlling a LED (because you are actually controlling a LED). You ca...

At the moment i was thinking about simple led staff.
I have tried with a small led connected to a gpio and latency was ok. It is why i think problem comes from RF.
Maybe a relay could do the job? Instead of a triac that seems to be more difficult to use with raspberry....

could you tell me if P11N60 is a photo triac?
thanks

thanks for your replies, guys to be more specific, i would like to use a pack of 4*50W lights, to trigger flash lights as you could see in band concert. at the moment, i have tried with RF power socket but there is too much latency between switch on/off. I guess i would dhave the same behaviour with...

i try to trigger flash light with a raspberry
i guess i need to use a triac for this, but i could not find any tuto, schemes.

thanks for any links that could help me to connect the triac to raspberry and how to use it

have you succeeded?

hello

have you succeeded?
i would be very interested

thanks
