stratologger question

[Rex R]

was wondering about the voltage output on the audio channel. PF lists that for use with an exterior beeper or LED, so the question is what is the max voltage? thinking of connecting an LED to it. thanks,
Rex

ah, so a 12ohm* resistor and a green LED should work, thank you.

*I will probably use a 15ohm as I can get them local, led will not be as bright.

after digging into my spare parts, I found a 3mm green LED. then went shopping. with a little surgery a 'JST' connector was made to work, used a 15 ohm resistor. connected the lash up to the stratologger, and powered it up. it works, now I can have a visual indicator as well as audible for the rocket. just need to do it up purty.
