Re: Input on the best way to build a portable scanner

Moved to the Origami Scanner- a folding book scanner thread,

spamsickle is making a remark about the adjustability of the camera mounts on the origami scanner as I first posted it in the next post.

Re: Let's talk about Lighting

UV is going to be produced. No doubt about it. Very little of the UVA band will penetrate the diffuser. I believe the correct diffuser, a combination of glass and plastic, would allow a very tiny amount of UVA to leak through. Sorry just am not concerned about that problem. Of bigger concern is desi...

Re: Let's talk about Lighting

I came across this while looking for a circuit that would work for HID lighting. I think this is slick. The maker, Wangtrirat says,”This is my Home Made Super Cheap Metal Halide Ballast and Igniter can use on Mercury vapor or High pressure Sodium Lamp too.This is Super Cheap System i've made about...

I would add the following link:

Re: E-reader smackdown: Can they read Google Books PDFs?

My suggestion is not to buy into the early adoption of an imperfect genre of gadgets. I suggest something a bit more mature like the Motion Computings' LS800 tablet. This machine was introduced in about 2005 and has been used rather extensively by the medical community. The LS800 is 8.95 x 6.7 inche...

They where a table that was the case. The case opened and the stools and legs of the table folded out. Much like the chair a...
