I'm not an EE, but have soldered simple circuits to repair LCD monitors and am well versed in auto repair and modifications.
I want to make a device that takes earphone jack output and flashes a light instead. In other words plugs into the earphone jack of my radar detector and flashes an LED in place of sound that would come from the speaker. Doesn't have to be synchronized or anything fancy. I realize that I'm losing quite a bit of info. in the translation, but I find that in most instances it only goes off at a necessary points anyway.
I would have 12vdc (actually between 12 and 15 volts to be safe) available to power the LED if necessary.
Thanks
