Change from CCD to CIS
Hello, First of all you did a great job and i use your pinscape since the early days. In the last days i concerned very seriously with the pinscape because want to add an anlog plunger to my cab. But the ccd construction is much more i think it must be.
I disambled a time ago a scanner and found an CIS wich should be the same method to get the darkest pixels. The advantage would be the inbuild RGB LED and so it is a smaller installation.
The cis i found was an canon CVA-60216K
Have you thought about this?

Hi - thanks for the suggestion. I expect it would be possible in principle. That particular part doesn't look like it's readily available anywhere, so I probably wouldn't want to build an "official" release around it. Even so, if you can find a data sheet for it (which I couldn't, although I didn't spend too much time looking), you could probably adapt the existing code to it, since like you say its operating principles should be similar.
It would indeed be nice to have another optical sensor as an alternative to the TSL1410R. They're not actually that hard to work with, but they're not super cheap, and we'd be stuck if the manufacturer stops making them. I've tried on and off to find another suitable sensor since I got started on this project, and so far I haven't been able to find anything. If you can find a part that's available for purchase (at prices in line with the TSL1410R), I'll definitely want to take a look. I'm not really keen on recommending parts that have to be scavenged from old equipment - I want the project be as much of a "kit" as possible, so I think it's important for all of the parts to be items that you can buy off the shelf.
