Not sure where this thread should go so please move it if required.
I'm trying to use the hot shoe of a Canon EOS 6D to trigger a 5v logic circuit for a Picaxe but the pulse from the camera is triangular with a width of about 130nS and a peak of about 950mV which is too small to amplify with anything I have.
I have:
OPA197 in a DIP socket
A few BC547C and BC557C
2x ZVN3310A
How could I convert such a small pulse into something a Picaxe can use?
