... my ham radio in loud environments. I assembled the audio converter needed to convert the mono 1W speaker outputs of my radios to the line level stereo input on my head unit. Here is the schematic and a pic with the cover off.
I only got 4 hours of sleep last night, so when assembling it, I got a little too literal when reading my schematic. So now I have an extra output if I decide to port it somewhere else (just got my creative juices flowing about running a line to the laptop input to record it...). Anyway, now all I have left are the camera mounts.
