I modded a scanner into a camera. This is ‘drake V’
(lemmy.world)
Taken on a small group of Islands in the Oslo fjord, called Hvasser. A 15 meter peice of fabric playing in the wind, scanned right to left in 21 seconds. Got really lucky with the clouds this time, allowing a single beam of sunlight in as a highlight.
Thats really Cool! Thanks for letting me know, this might be the impetus I needed to go back to working on the 220 camera!
So, when I say "change the image", I mean the torch does affect the calibration, in the sense that I get different patterns of stripes based on the position of the torch, but it's still just outputting stripes.
Here are two scans I made by waving the torch around randomly during the calibration, then resting the torch on the glass.
For some reason each pixel is just outputing the same brightness for the whole duration of the scan, except for that black spot where the torch is, which is weird.
So, I re-installed the prism, luckily it just slots back in. I'm not sure if it helped at all, I still get the much the same result most of the time.
I did manage to get this result. It's black at the top because the lid was closed. I opened the scanner half way thru, and the scan turned white. Then I waved the torch over the sensor and got a definite zigzag. And there's a hint of grey in the middle, which is encouraging.
So, the sensor is still working, it's responding to light, just not in a usable way.
