Paul C. Buff, Inc. Technical Forum

Sounds like a challenge ;)
Good to see you back in the forums Paul...was worried something had happened to you...

I check in every day, and Tech does a good job. I've been incredibly busy and my health hasn't been the greatest,

Regarding doing any sort of remote control of Einstein, I can tell you it takes 256 bits of data following a very specific protocol.

All it takes to control an analog RJ11 classic Buff light is two analog voltages and a trigger pulse. Big difference.

Not interested in talking the Einstein protocol actually. I'm trying to get the CC/CSRB+ to control speedlights via the quench signal.
Got most of it figured out already except how to read the trigger pulse and generate a delayed version (turns out a microcontroller is about the same price as doing the circuit w/ a 555 timer and analog parts...crazy).
I'll hopefully know in a few weeks whether it works after I get a bunch of parts...got enough of a lull in my current project for some hacking time while I wait for other people.

Stay healthy, Paul...

OK . . . Controlling a speedlight via quench signal may be possible, though the CC end is still going to be tough. I suppose if you don't touch the CC, but look at at the CSRB analog output with the right circuitry you might eek out a quench pulse somehow. But there is no volts vs time sort of ramp involved so I wouldn't know where to start. You'll probably have to creat a ramp tuned the the specific speedlight that is triggered by the trigger pulse.

That's exactly what I plan to do...ramp tuned to one "standard" speedlights and then you can use the modeling lamp "power" to tune the ramp slightly if you have a speedlight other than an SB28 which is what I plan to use as the "standard".

On the CC end, I just plan to lie to it and tell it that I'm hooking up a B400, though I wish there were a setting for B150 which is probably what most speedlights are if you zoom them to 70mm :-)
You obviously won't have the cool CC feature of letting you change the entire setup's F stop from one button, but it'll let you control one speedlight at a time and test one speedlight at a time (the latter feature is what irked me about the RP JrX...that and not being able to adjust the ramp if I wanted to use a Metz hammer).
