Rolson 6mm Titanium Signal Injector

One things leads to another - this is especially true in electronics.
Inspired by Homer L Davidson who used a LM3909. Tragically I had to think on my feet due to it being discontinued. Homer used an ugly 90's plastic case for his - the wife was just as unimpressed with my effort. Booooooooooooooooooooooooooop.

555 Astable @ 1khz. Can't wait to test my broken audio amp (Cambridge Audio) - at least I know to start at the volume control. I suspect the relay due to too much Led Zep but once again am fiddling (carefully) where I may not belong......


Its inspired the next mini zen soldering exercise . Order up! - a 440Hz 'A' note tone tuner.


Note to self: try not to think out loud on the forum - may get lost in translation. Googlepedia mercilessly before posting.:)
