(Though my class of 13 year olds will probably ask "Is there an App for that? ")
What frequency RF is possible from a chip like this, by the way?
Thanks.
This is a circuit implemented in IBM 9HP (90nm Silicon Germanium BiCMOS) that can produce an RF power waveform from 0 to about 10GHz with a digital input. Thus the name, "Direct Digital to Antenna". It's intended to replace conventional RF transmitters in power areas less than ~10 watts with a much simpler and with broadband frequency coverage. based on my 7903016 and 7939857 US Patents from 2009.
Sounds like you've got some inquisitive kids, that must be encouraging and trying at the same time

It has to be done inside Zerene - if your photo, let's say 000, was on the right and 007 on the left, you have to move your photo to the opposite side-000 to the left and 007 - to the right (make left window active and from the output photos choose 000, next make right window active and choose 007). And afterwards - generate stereo pair. Now your stereo looks "inwards" . PS flip will not help.

Thank you.
The 4X is from WeMacro.

It does not cover the FF sensor and vignettes, but because of the subject orientation this doesn't affect the image. Of course it would be better with the smaller DX sensor, but my vertical setup uses the D800E now.
Hope this helps.
Cheers,
Mike

Probably not going to be able to get to this anytime soon. That will take too much time, sorry.
