Re: A new scanner design using plastic tubing

Hi David Yes of course - but that's easy. You use the same 90 degree brackets as before, but mount them a little distance away from the edge of the book supports. The distance can easily be worked out with 'trig'; I have done it once casually, will go through my notes again to be sure before cutting...

Re: A new scanner design using plastic tubing

Hi David One other factor that comes to mind if you decide on a wider 100 degree platen, and that is that you will also need to make your book supports to hold a 100 degree open book. I wonder if you have thought about that? Yes of course - but that's easy. You use the same 90 degree brackets as bef...

Re: A new scanner design using plastic tubing

Oh, one other thing - I haven't yet seen the change with the D-loop, but something that occured to me re. weights and balancing: Considering the (fairly small) weight of the cameras, platen etc. I was expecting the necessary weight at the back to be somewhat less than the 2x 0.5kg (ie around 2lbs) y...

Re: A new scanner design using plastic tubing

Hi David Thanks very much for your important corrections! What appears to have happened is that I've drawn up dimensions for two sizes of scanner, and some of the pages for one size have got mixed with pages from the other size scanner. BAD NEWS :o :( No problem, glad the info was useful. I will kee...

Re: Cameras for the Hackerspace Scanner

Hi Daniel A1400 is well supported by SpreadPi - I'm not sure on the status of the A2500. Chrome is easy to tape over or paint, so don't let that guide you too much. OK, thanks. I am hoping that I may be in a postition to assist with SpreadPi at some point; regardless, I think I'll stick with the A14...

Re: Cameras for the Hackerspace Scanner

Hi All here in the UK I can get either of the following Canon Powershot 'A' cameras cheapish (ie refurbished by Canon): A1400 and A2500 The main differences between these two models that I can see are: A1400: optical viewfinder (handy for non-bookscanner applications, perhaps) a bit 'chunky' A2500: ...
