Re: A new scanner design using plastic tubing

I expect the cameras and the mounts to come in this weekend The images you have posted look very good. Have you now got the cameras and mounts? I'm really interested to see how the scanner works "in production mode". I'd be interested and happy to discuss any snags or problems you may hav...

Re: A new scanner design using plastic tubing

Thanks for sending the excellent new photos. It is looking very good. A couple of points and suggestions. I looks like you have bent the platen rather than gluing, but I may be wrong. If you have bent the plastic, I'll be interested to know a. how you got that bend and b. whether it will fit into th...

Re: A new scanner design using plastic tubing

First of all, thank you David for creating this design, for documenting and sharing your work, and for answering all of the questions with detail. I'll repeat what others have said, that I'm not a skilled engineer or builder, but since your design seems the most feasible for me, I'm going to try to...

Re: A new scanner design using plastic tubing

Is it possible to use a glass platen? And then hold it in place without gluing anything? Just held on the sides somehow? The advantage being glass is less scratch prone, probably cheaper, etc. That's a good question bsbob, and some commercial scanners to use glass. There would be a weight factor, b...

Re: A new scanner design using plastic tubing

Just found this video on how to put a plug on the light if it comes without a plug

http://youtu.be/bPkX4F-Wk84

It's a simple job and just takes a few minutes and you can do it with just a pair of scissors or wire cutter and a screwdriver Hope this helps!

Re: A new scanner design using plastic tubing

The lights came with a length of three core electric wire. I added a plug, and plugged it into a wall socket. Pronto! Lights on! Basic question, but.... How do you add plugs onto bare wire like that? Those flood lights look interesting. I've never connected anything like that before. I'm concerned ...

Re: A new scanner design using plastic tubing

Did you have to wire those lights in yourself or do they plug into a standard outlet? Is there such a thing as too much light? I'm thinking more lights... More light, brighter pages, less shadows... Maybe more chance for reflections though. The lights came with a length of three core electric wire....

Re: A new scanner design using plastic tubing

I've just bought a low cost LED floodlight. It cost about $20 US on eBay I've ordered the 10w version. What are you finding the colour temperature like on yours (I presume you ordered the cool-white?). Could you post some samples using the best white-balance setting for your camera for your light? ...
