As you can see, this is mostly a "New Standard" scanner build. The #1 design objective was that I needed it to break down easily and not take up too much space. I know my time at the Dining Room table is limited
- The full scanner.

1. If in doubt, I used a bolt instead of a screw. This includes the connection from the column sliders to the platen.
2. Inspired by the folding air platen, I made the platen hinged in the middle. The cross bars at the top are held in place by 4 screws with wing nuts. The screws are perpendicular to the platen support. When tightened, it forms a good solid triangle. When taken out, the platen folds up nicely.
- The platten is hinged in the middle. The top bar in front and back are held in place by screws with wing nuts. Take them out and it folds flat. You can see one of the wing nuts on the underside, near the top right corner.

- The cradle. Both the left and the right are adjustable. And you can't see it, but the 45 degree support is hinged to the cradle base. So the two supports fold flat when you remove the screw.

- The counter weight. It is just a 2 inch PVC pipe capped at the bottom, with a screw on top. I just filled it with scrap nails and extra BBs I had. I used a 3 inch PVC pipe as the guide.

- Use the blank back side to slip between the book cover and the first/last page of the book. This cuts down on getting images of the book cover, which can case problems later in post processing. I've also found it works well on very thick books if you place it within a hundred pages or so of the pages being scanned (you cut out a lot of the feathered pages that get caught in the picture.)
- On the other side of the card, I pasted a picture of a ruler (which I verified after I printed it out.) I found mine at http://vendian.org/mncharity/dir3/paper_rulers/ but there are others out on the web. So now that I have a ruler always handy, I take a DPI calibration shot as the first set of pictures of a scan.
- Since the cards are cut to the size of the top of the platen, when the scanner is not in use, I just lay them on top. They act as a cover that prevents scratches to the top of the platen as well as dust from accumulating.
- The "Platten Card" laying on top of the platten to protect the top surface from scratches and dust.

Also, on lessons learned (most of them you will say "duh", but I will state them anyway):
- When you buy cameras from ebay, take the time to do a full reset on them so you know your starting point.
- Take the time to figure out how to adjust for indoor lighting.
- Make sure both cameras are at the same zoom level
- The bulbs get real hot
- Asking where you want the project and creating the directory if it does not exist
- Asking for a starting page number (in case you break up a big scanning project)
- Asks if you want to convert to greyscale
- Asks for DPI for left and right if you want to add to the images.
