Today a small camera board made by Sanm arrived in the mail from Hong Kong. It came without a USB cable, just a 5-pin header, so I used the pinout diagram on its product page and wikipedia's USB pinout reference to put together a cable.
Then I took out the filter by unscrewing the lens and prying it loose, closed it up, and plugged it in, and it worked. It identified itself to my computer as a "BisonCam NB Pro" which appears to be the internal webcam of the MSI GT780R.
The camera has a sensor half the size of the Syba webcams that currently come with the desktop spectrometry kit, and the board is much thinner 60mm long:
The board has a bright white LED on it that needs to be covered. I put some electrical tape over it:
I mounted a DVD fragment using two layers of double-sided foam tape:
In order to get a flat surface for mounting, I used the broken off mounting point of a Syba cam, and stuck the Sanm board to the side of it with double sided tape. In this photo I marked where the body of the Syba cam had been with a pen, and ticked off the lens location, for comparison. I believe my lens placement for the Sanm camera is roughly the same place as the Syba cam:
The Sanm cam barely fits. It sticks beyond the lip of the conduit box, but the lid bulges out a little bit and closes fine:
the results are a little dim, despite the otherwise great quality of the camera. Any thoughts?
It is possible to do less downsampling. Hopefully this'll be part of hte Capture page refresh. Originally it wasn't a high priority since it was already way past the expected resolution of the device. Now, people are challenging that assumption :-)
all the Public Lab spectrometers will suddenly have more resolution?
Yep!! Not retroactively, however. But really, many things we do in the software will "improve" the hardware. Such as noise reduction, or baselining, or autodetection of calibration lights, HDR compensation for overexposure, etc. One great thing about doing a combined hardware/software platform.
