I want to build a very simple circuit (probably some kind of dongle, probably on the cable between the trigger and the flash, incased in shrink flex, or build into an in-between shoe), that will delay the flash trigger current from a remote trigger, from about a 30th of a second to maybe a couple of seconds.
I want to use Vivitar 283s as I have a bunch of them, filters and Varipower, so it only makes sense to use them.
The idea is to do spatial-temporal strobe effects, with multiple flashes going off slightly delayed WRT to each other, while the subject or camera moves
There is the usual old three component capacitor, transistor and resistor thing for delayed switching.
But:
- Will it work with a remote trigger? How does the switching in the trigger actually work? Is it a very short pulse, or does it keep open until it can feel current flowing?
- And how do I scale the circuit for the much higher voltage of older flashes?
Is it possible to simplify the circuit even further for this application? For example just a capacitor and a resistor in series?
Naturally in any case you'd have different capacitors for different timings.
Direct advice, or inspiration from other similar projects would be welcome.
Caveat:
Don't suggest stupidly expensive triggers that will do the same thing (aside from breaking from the voltage from the V283s).
Don't suggest elaborate wired boxes that will do the same. I want something simple that can easily be hooked to individual flashes with a remote trigger, doesn't take up too much space and doesn't cost too much.
