Ok I have been on and off with this for a few weeks now but I still can't get this work how I want it to
I want to activate my flash by a sound input.
I have tried various so called sound trigger circuits but to no avail. The Rev-Ed sound circuit does work albeit very limited but I couldn't get it to trigger the SCR.
I am in the throws of working on this circuit, and I get an output on my scope but no trigger. The output is very sharp and quick, maybe to quick for the SCR, so disconnected the SCR and put the output onto an LED, still nothing!
I just want a simple circuit, hence the LM386, to activate the flash, with a pot to adjust sensitivity so background noise can be discarded, pick up very slight noises or very loud noises. Am I asking to much? Does anyone have a solution? Can this circuit work?
