I'd like to use this Neewer CN-160 for flash photography at around 1/500s.
Before I burn out this bank of LEDs, does anyone have a suggestion. Also, this unit does burn out batteries even when switched off, so it has it's own set of problems.
Ok. I'll rebuild it.
Not giving us much to work on.
I changed my screen name. I wrote this post.
I want to photograph night blooming cactus, and I also want to photograph freeze frame shots of the hummingbird that visits my garden. So, I need to sync with my camera on the flash and be able to change the flash duration.
I wanted to use the led panel shown in the attachment, by removing the on/off switch, and connecting those wires to an optocoupler on the arduino. That may not fix the battery drain.
I'm a total noob at this, of course. Thanks for the reply.
Hi Craig. I suggest you either try this forum or, as Crossroads says, start giving us a lot more information.
You need to take better photos of the circuit boards with special attention to the writing on the ICs - it needs to be readable. The green board appears to be double-sided so a picture of both sides might be required. You also need a picture of the back side of the LED board so we can see how it's wired up.

Why? A speedlight will do this much better. For hummingbirds, 1/500 isn't really fast enough. A "thyristor" type speedlight can produce flashes as short as 1/10,000 S. at low power. The colour rendition will be superior as well.
