Sound triggered flash

[b._p.]

<p>After a DIY disaster (spending $35.- and 8 hours of blood, sweat and tears), I found a simpler solution to make a sound trigger for a flash. The article seems rather old because they talk about film.<br>

I have a few questions:</p>

<ol>

<li>They write to use a 400 volt BRY 55 400, which is a SCR (Silicon Controlled Rectifier, no idea what it means, but I can solder it together). For a SB600 would that be correct or too much or little?</li>

<li>What kind of store would sell those? I live in Portugal where electronic parts are more rare than gold.</li>

<li>Instead of an old tape recorder, I'm guessing I can use my PC or notebook for this? I think it's easier to control both the mic and the out port, but maybe I'm wrong?</li>

</ol>

<p>I'm still trying to find a PC sync hotshoe with a cable, but no such luck. Probably have to import it from Holland or something.<br>

Thanks!</p>
