I'll be able to test this... because I broke my IR filter. I'm very curious if it'll get better results. I'm rebuilding/improving my 35mm adapter right now, so I can choose/experiment where to put...

Maybe we can keep in mind, lots of the batteries for 'consumer' DV camcorders are 7,2v. Is it also possible to convert that to 48v ?

The viewfinder is about ready and working great. I haven't had time to put the sensor and main board back in the camera body, but that'll be ready tomorrow.

Viewfinder update...

The optical viewfinder is almost ready to be mounted on the Elphel. I will make it detachable, so I can always adjust things. And I'll probably make another one without the image inversion, so I can...

Andrey, ..this goes a bit above my head I guess. With data, do you mean in the form of a histogram or something?

I had some great tests with the viewfinder. Very clear and bright image. Perhaps it'll even be good enough to focus most shots. I still have to put everything together though and make a robust...

I've made some progress with the viewfinder. Making everything adjustable so I can focus everything right will be difficult, but you can see it should work out.

Matteo, I'm not sure how you want to have the mirror reflect the image from that angle without a perspective distortion, or am I missing something.

Happy new year to everybody.

I'm busy making an optical viewfinder on the Elphel 353.

Hello all,

I wanted to shoot new footage in France last week, but the circumstances (weather etc) made it too difficult to experiment.

I'd like to discuss an idea that came to mind about...

That's a wonderful start Daniel. I'll try it on my 333. Great to see software development. Andrey is working on the software for the board to record directly to hard disk (for the 353 model)

Daniel, that sounds easy, but somehow I didn't get it to work. I'll give it a try again tomorrow. I'm interested in Ubuntu because it's suited to be installed next to XP or Vista (in my case) onto...

Odd, that's about the first next (big) step we should take with the Elphel.
About the audio, I know someone at Elphel was testing sound recording, but that's in early stages I guess. Synchronizing...
