My first and second builds...

Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

My first and second builds...

Post by alrumich » 02 Mar 2010, 11:22

Inspired by all the designs I found on this excellent website I decided to build my own... it took about a month until I started to plan the second build :)
Below are some pictures of the first version. There is not much original in its design, except for, maybe, the platen, which is, basically, just a box with a handle. Yet, it is rather efficient.

The second build was inspired to a certain extent by all other builds here, but especially by that of IcantRead; many thanks to daniel_reetz for starting all this :)

Love the detached platen idea and the handle out of line of sight of the cameras. Is it light enough so lifting it 200 times is not an issue?

On your second build, I don't see what keeps the two halves of the bookrest from sliding apart and letting the book fall open wider.

On your second build, I don't see what keeps the two halves of the bookrest from sliding apart and letting the book fall open wider.
#1 :: It is light enough: two pieces of particle board (11" x 11"), two sheets of thin Plexiglas (12" x 14") and an almost weightless handle. At first, there was some discomfort (I guess that depends on the height), but then I could make over 1,000 images w/o even noticing it. (You do not need to lift it too high to turn pages).

#2 :: As you can see, one half has a long "tongue," while another one has an extra plate, which makes an opening through which that tongue comes. I can adjust the width moving them apart or joining them together, yet the "tongue" goes into the opening tightly enough to keep both halves from sliding apart. Simple and effective. Although, of course, time will show how practical it is.

I saw the tongue; I didn't get that it fit snugly. I thought it was just a support for the book spine. I guess that's what you can do when you have more than a jigsaw and a drill as tools. :D Thanks.

Actually, I only have a jigsaw and a drill. Moreover, I do not have a workbench or any other working surface except for a floor in my basement. I wish I could have access to a table saw. Anyways, it is doable with a jigsaw, even though rather painful (and not only figuratively).

As to fitting snugly, I think what is important is that the surfaces are large enough to create necessary friction, while the edges may not be as precise as one may want them to be. It is very difficult to make precise cuts with a jigsaw no matter how you try.

Wonderful "adjustable" cradle. I've been out of synch with the community; however, I've been brewing a different design, in which I also need to prototype to see if it is practical.
I love the diversity.

I like the cradle improvements. I think I need to do a full overhaul of my cradle, maybe this weekend. One suggestion, you may want to make the middle bar a little smaller. You only really need it as wide as the slide you are using. I think the bigger it gets the more in the way it is.

My brother's got a table saw, but I've never needed it for my scanner project. My power miter saw has been able to handle everything I need. I see you're in Ann Arbor, if you can make it to Grand Rapids, you can use anything in my workshop.

Go Blue.

holy kerfection, batman, you did all that with a jigsaw? Here I was thinking "I'd love to fab like that if I had a tablesaw/woodshop"...
