Shutter speed.
Mydesign   4/20/2012 3:26:14 AM
James, normally digital cameras have a shutter speed for 1/500 to 1/5000 of a second. Moreover in a second we can capture maximum of 15 shots. What I understood is that, the mechanical parts/components required a minimum time to complete the process; irrespective of the shutter speed. I mean the system introduce a minimum delay between the frames for completing the capturing process.

I appreciate your effort, can you justify the need for such a fast response system.

I agree, Naperlou. The article doesn't say how much he spent, but the bill of materials indicates that the most expensive component was the breadboard at $20.19. There's no price listed for the camera, but it's probably no more than that. Amazing.

There is no ground connection to the SCR in the schematic but the breadboard shows the black lead from the flash connected to the ground of the circuit. Looks like a fun project!

Thanks for submitting a cool gadget, Jimmy. I thought the comment about underwater photography was interesting. Since the flash only occurs at the moment of the shot, there is no light to scare away deep-sea creatures.

I haven't scanned most of my high speed negatives (I'm still a film guy for a lot of things and I make my own prints when I do things like this)

I may dig up more negatives later, but a few of my first shots from the initial testing can be found on my website's gallery page (can't post a direct link at the moment): jhartnett.gawsolutions.us

As well you can find details on other projects

And @ Rob, thanks for the feature!

That's a really good question, Nadine. With some modifications, I would imagine it could be used for deep sea. You already have the dark, so it's just a matter of a quick flash for illumination. So you can shoot the fish (so to speak) before it scares.

This is intersting.  Because the shutter has to stay open, the applications are limited.  But, could this be used for deep-sea underwater photography?  Imagine what we haven't seen because sea creatures are avoiding the bright lights used now.

It's amazing how few components are required sometimes.  Good project.

Cheaper alternative to a high-speed lens

Looks like a pretty interesting solution and likely a lot cheaper (and much more fun) than buying some sort of expensive high-speed lens. I'd love to see the fruits of Hartnett's labors in terms of how his gadget actually performs vis a vie picture quality.
