  1. That actually looks like a great lighting solution. Good physical profile, spread, brightness/evenness. I may switch to this if the cheap lighting option I bought doesn't pan out.
  2. It's funny you should ask. I actually never completed mine. But in the last year I moved, and recently unearthed my half-baked projector. In the last few months I've gotten much better at writing python on raspberry pi, and so I've re-added this project to my list. I had purchased a USB macro camera that has a GUI but can be controlled by OpenCV, so I'm hoping I can tap into that on Raspbian. Eager to hear how others have fared.
  3. Pol, my hat is off to you. This is real quality work. I got sidetracked last year by my project. I'm inspired to (find the time to) get back to work on mine, and take it to the next level! For a coding "novice" I don't think you're giving yourself nearly enough credit. Thanks so much for sharing all your work!
  4. So, I've successfully gutted my Bell&Howell projector, and written a really basic Arduino sketch that's successfully advancing frames. I'm pretty stoked about all this. Today I'm receiving a pretty cheap USB Microscope camera from Amazon that I'm going to try to get to work with the whole setup. Josh, can you post your Python program? I think it'll work with the camera I bought, because the computer should treat it like a webcam, and I know you said your program worked with your iSight... Once I have a complete setup in place, regardless of how *good* it is, I will share with the forum!
  5. Anybody have any add'l findings on those USB microscope cameras Josh mentioned earlier? Esp. re: whether they can be made to work with OpenCV?
  6. Thanks for posting your code, Josh! I may try to write my own code, or clean this up a little, and if either of those things happen I will post my results. I'm probably not much further along than you coding-wise, but I think there are a few if-statements that could benefit from an && instead of being nested, and your different StartByte evaluations could be cleaned up by being converted to Switch statements! I might also suggest GitHub again, as it would be a great place to congregate over the code: pull and push requests will allow everyone to democratically arrive at slimmer and more efficient/effective code; forks will allow people to also make their own version for special cases; it will shield people who are more interested in the optics/physical engineering/etc. from having to listen to nerds talk about code! But if it's just you and me who are interested in the code side of things, maybe that's not necessary. Thanks again, keep it coming. Close-ups of your breadboard/pinout board requested in particular :)
  7. Interesting idea. If you didn't mind getting down-and-dirty you could run the HDMI feed live into a video capture program of some kind and just trigger the computer to take screen grabs at the moment you would otherwise trigger data or a shutter release, and just crop in post. Obviously there'll be some quality loss there but certainly a quick solution if you're not super interested in post-processing the image!
  8. Good point about the DSLR! I'll probably just use my old 30D since I don't care too much about it. Or maybe buy a used one online to care even less about. Yes! That video would be incredibly appreciated. As for where to put the code... GitHub? Less interested in the 16mm because I don't have enough shot that I'd want to build a version for it, but I'm sure someone else will stumble upon this and want it so I say go for it! Also, I noticed we're both in LA. I'd love to come check out your setup, if that wouldn't be weird for you. No pressure there, feel free to just post the video and code. Thanks for your help!
  9. Hi Josh! I bookmarked your post and thread a while back and have finally started delving into the Arduino world in preparation for making my own version of this project! I was wondering if you could share with me StepCapture and your Arduino sketch? I bought the stepper motor and have an Arduino Uno. I'm thinking about trying to mod this for a DSLR setup but I just wanted to see the guts of how everything is working for you. An electrical plan would be cool to see too!
