Re: BookGapCheck: Quickly check if there are gaps or duplicates in a set of book page scan images

Thanks for posting. It's an interesting tool and could be quite helpful. I first heard about this technique in the video describing the Google linear traveling book scanner in 2012 and thought it could be handy ( Google open sources a DIY page scanner ). The section of the original YouTube video des...

Re: a small story for my scanner

if you ever gonna build something based on this designs contact me Why would someone need to contact you? BTW, that "billgill" design came from another user on this site many years ago. Bill has actually come up with a new design of his own that is a vertical rectangular tube with the platen at the...

Re: Original ~600pg/hr, very portable scanner now achieving ~900pg-1100pg/hr

Thanks. I've built a lot of stuff during my lifetime and made plenty of mistakes along the way and eventually learned what works and what doesn't. BTW, one thing I forgot to mention is that when you're dry-fitting PVC parts together, they likely won't insert as far as they will once you get them wet...

1b. Once try, glue the second one on, and place the handle with the two 90 degree elbows on a table (or kitchen counter) and rotate the second elbow so the open ends of both 90 degree elbows are face down to the table (as if the handle was attached to the table and going to lift it). That would pro...

Re: Original ~600pg/hr, very portable scanner now achieving ~900pg-1100pg/hr

Here's how I would glue that handle together to minimize the chance of a misalignment: 1. Glue the two 90 degree fittings to the handle. Getting these to be in line with each other on such a short length of pipe is pretty easy. 2. Glue the two 45 degree fittings to each of the vertical arms. This re...

Re: Original ~600pg/hr, very portable scanner now achieving ~900pg-1100pg/hr

Yeah, I realize you were prototyping and that system you developed allowed for some amount of experimentation. I was actually responding to GenioDiabolico who probably just wants to get his book collection scanned and not mess around with new steel cables and pipe lengths. To be honest, if it were m...

Re: Original ~600pg/hr, very portable scanner now achieving ~900pg-1100pg/hr

I have the 3/4" PVC for the handle and the 3/4" barrel nuts do work but are a bit scary in that they basically are flush with the edge of the outer part of the pipe. IOW, there is only the thickness of the PVC holding them in. If I understand you correctly, you're saying that the ends of the cross ...

Re: Dire camera situation 2017

Just something to try: Does the camera write to the SD card if you don't use your remote trigger? I looked at using CHDK years ago with my Canon point-and-shoot cameras and got frustrated and bought a pair of Canon DSLRs and used their SDK to control the cameras with my scanner from some software th...
