In Topic: Microflash to fire optical strobes without using camera's flash

31 May 2014 - 11:40 AM

Hi everybody,


I'm planning to do a kind of Microflash by myself if Carlos did not put it into production soon :).


Some improvements I would try:


- 5.5V 1F super capacitor (rechargeable) instead of coin batteries.

- Microprocessor for special strobe effects, like delays and multiple triggers.


If I had the time I would implement S-TTL as well, but it is a lot of work.


Kind regards,

Hello Harry,


I'm doing the same movement from DS-125 to YS-D1s. I'm also moving from Aquatica D-300 to D-7100 (or anything more powerful before November 2014).

I've been shooting manually for long time and I would like to move to TTL in some macro conditions.


You said:

"The only real downside that I see is the increased drain on the camera battery"


I saw somewhere (sorry!) a circuit that goes on the camera's bulkhead that triggers 2 leds through the housing optical bulkhead. I'm not sure it is a TTL converter as well or just a standard optical trigger. It would save you battery life.


It works like S&S one, without TTL




Best wishes !
