Electronic textbooks with their own hands
Recently, some puzzled question. Textbooks.
He saw how the daughter drags with him is just PPC. There are 5 kg bag. It's just!!! textbooks, manuals, notebooks, stationery, etc. Oh, and sports uniforms + indoor shoes. In short we must do something.
Essno thought - electronic textbooks, at least for weight savings.
Another aspect - the economic one.
Our Russia "free" education and let him go wood, especially our publishing "mafia". Well this is a set of textbooks for 4000 p. out, if you take the new course have to get out to buy b / y. But still a significant amount. Maybe for someone insignificant amount, but that's another topic. The same textbook, but different editions (the difference in a couple of paragraphs), but all right to buy a new one. In my opinion it is a sabotage and thirst to cut the dough in education.
Okay, steam released) back to the sheep.
And just NG))) Given the daughter plate, left to fill it helpful. Searching the internet tutorials is little that is. Got one page VKontakte, most importantly, what's the book sent free of charge, if they are, well, at least scan the strength and capabilities, for what they and others Respect Respect.
It was the preamble)))
Given: A solid tutorial
Exhaust: The electronic textbook (pdf / djvu)
The process itself is simple: scanning and forming pdf. Everything rests or money or in time. If we take a simple flatbed scanner, then tired of each time to lift the book, and the slower it - minus the time. For the money, to order to give filigree toad strangling. I decided to take advantage of that found at home. Fotik Nikon3100, a piece of Plexiglas 30h28sm (approximately) then to choose the format for, I have what was then taking. 1, 5 m plastic pipe 20mm, 4 corners, 3 T-coupling, 2 pins 1m * 8mm, 17 nuts M8 washers to taste), a bolt 8, M6 screw (it is mounted camera down), wing nut 6. It seems everything is, well, plate, fasteners for the camera down, I obezok chipboard.
The process of the assembly will not spread sufficiently simple, show the finished product and the individual nodes, you realized that and there, sure.
I will note at once, why not focus just come with a tripod and a book was such an idea first. Minusy- Record Book is necessary to position each time, and when she pressed down the glass, then the pages are not exactly in focus, and root letters clear and fuzzy at the edges of the page, or vice versa, try it yourself)
Sobbsno product itself, gone:
Now separate units:
studs 1m. cut in half, I got 4 pcs. 50 cm. This is the main pillar and a predetermined distance from an object, you can bet more or less immediately guided to your camera, and how are attached to the Plexiglas. I'm in the black washers, such a habit. ))
Corners. All soldered soldering iron, oddly enough, but if you are strong, then you must also succeed.
Fasteners fotika. Boards screwed onto the bolt, which is scored in a tube.
Bolt 6 in camera down in a regular place, attract wing nut.
Top view of the entire structure. T-shaped couplings have a file or to modify or ream or some other way to expand, they have to slide through the tube (vnatyag) to fotik can be positioned in a horizontal plane.
More options offset
another angle
fotika fasteners, nut filled pistol
