Re: Light mount height?

I'm building my first scanner, and I realized I didn't know what height to mount the lights at. On the rig we're building the lights are at the 'new standard' height, the variation is largely the lights. We're using two contrast enhancing compact fluorescents (I forget the lumen's rating) I have tw...

That's pretty cool dtic!

Re: Clarification on platen design

I bought two ready-cut sheets of Plexiglass (enhanced acrylic glass, according to its manufacturer) with the dimensions 260 mm, 320 mm, and 2 mm (thickness) in a German shop for 1,63 € each. Great price, isn't it? For retail precut that is not too bad (I don't know whether you got FF or GP acryli...

Re: auto page turner prototype

a.jpg See attached video (zipped .mkv since upload form didn't allow mkv). The "big finger" is a rubber eraser. The "small finger" is a thick drinking straw. To use a double platen you'd need two (properly timed) forces. Reliable finger action is a challenge but the device now performs fine on a 30...

Re: Clarification on platen design

in the hopes that I can arrange to have them create a platen of 90-degrees out of 3/8" cast acrylic (my understanding is that 'cast' acrylic is higher quality than extruded acryllic). I like the idea of having the acrylic platen have its own integrity (ie., from being molded together). My thought i...

Re: The New "Standard Scanner"

New images! I'm close to done with the counterweight and assorted mechanania. Since my platen is quite thick (3/8" cast acrylic) it also has got a fair bit of weight. To make scanning easier on the arm it HAS to be counterweighted. It's been a slow process. The stumbling block has actually been what...

Re: The New "Standard Scanner"

New image! I worked below the scanner this afternoon. The idea was to reduce clutter and avoid a morass of wires everywhere. Using some leftover wood I glued in a small shelf in the base to attach wires and powerpacks to. The rubber bands are temporary, they will be properly tied up later. We also h...

Re: The New "Standard Scanner"

Mathue: Wow. Beautifully done. I am really impressed with how far you've taken this. Many thanks Mr. Reetz! I'll add some new images once it's completed and it has the cameras, lights and 'reetz switch/handle' mounted. (I'll tell you the moment I know if I'm moving for sure -- the last week has bee...
