Hello,
I'm trying to build a microscope for SMD rework. My idea is to use a small low cost Raspberry Pi to make a full HDMI self contained microscope.
I used a Raspberry Pi camera on which I only exchanged the camera lens with a lens coming from DIYINHK lens. Their lens has the advantage of being focused to give you a working distance of about 15cm between the lens and the target board.
The camera I used is this one (I exchanged the lens as explained)
http://www.ebay.com/itm/New-Camera-Modu ... Sw9IpXzXRR (http://www.ebay.com/itm/New-Camera-Module-Board-5MP-1080P-222-Panoramic-Focusing-for-Raspberry-Pi-/262581961215?hash=item3d231ac1ff:g:mWgAAOSw9IpXzXRR)
Here are first results (images took using my smartphone, I could have saved images directly on the raspberry tought). I tried to move a screw driver near small parts to mimic a soldering iron movements, and with a scene perfectly illuminated, at only about 24 fps, I don't notice any image bluring.
While I think this solution can give a nice HDMI microscope for hobbits, I really hated the fact that this "digital" microsocope don't give me the depth sensation. I'm accostumed to the work sterio microscope.
NB. I didn't fixed the camera firmly on a handler, so the images are not 100% perfectly focused, when I was doing my trials, I could have really better images than those. I'll try to make a clean setup on true modular handler and will publish better photos in upcoming days.
