Technology

High Tech, low-tech, old-tech, appropriate technology. Those in the public domain can also be useful as clip art sources for writing tutorials.

At first count, this page had around 200 free technical books, including 50 books on machining, 9 on welding, 23 on material properties, 1 on blacksmithing, 6 on other metalworking, 2 on woodworking, 2 on hydraulics, 6 on motors and generators, 7 on drafting, 21 on electronics, 2 on thermal engineering, 8 on physics, 22 DOE handbooks, 35 tube era electronics, 3 on chemistry, 5 on Units of Measurement, and 4 related to CAD, and misc others.

Machining

Although there is some newer stufff, Many of these books are of order 100 years old but manual machining practice hasn't changed that much in that time period. Today we have CNC and better alloys and some new cutting methods. But the practice of turning between centers goes back 5500 years, if not longer. Metal lathes emerged around the 16th century, cylinder boaring 1775 screw-cutting engine lathe to 1797, change gears to around 1800. Also, back then they might be more likely to make a tool than buy one so the age of the books can be a benefit. The shaper dates back to 1839. The miling machine was invented by Eli Whitney in 1818 and refined in 1862. The turret lathe was developed some time during the 19th century. In 1896, the gear shaper was developed. Grinding machines and artificial abrasives were developed in the late 19th century, though use of abrasives goes back much further.

The internet archive now has a lot of books that weren't scanned when this page was first written. Note that many of these books are rare; some I looked at had maybe half a dozen copies at libraries throughout the US with the nearest copy being hundreds of miles away. Electronic versions make these much more accessble to the people who need them and many have aready been downloaded hundreds of times. Being rare, they might be hard to obtain through interlibrary loan, as well. I suspect these books may see more use in the first year of scanning than in one or more decades before scanning, due to geographic limitations.

Material Properties

• DOT/FAA/AR-MMPDS-01 Metallic Materials Properties Development and Standardization (MMPDS) 1728 pages. The NTIS sells this for $228 on paper or $168 on single user CD-ROM, yet as a government publication it should exempt from copyright (and indeed has no copyright notice). Supercedes MIL-HDBK-5, and required by the FAA. Was available for free download from FAA but they keep moving it. This has been succeeded by MMPDS-02 and MMPDS-03 ($600) which is supposedly "licensed exclusively to Battelle Memorial Institute". Now, they may have contracted battelle to do the revisions on 02/03 (in which case it isn't a government product) and thus the public's rights have been sold down the river in yet another case of corruption. But -01 has no copyright notice and purports to be the work of a government agency. MMPDS-01 is reportly "technically identical to" MIL-HDBK-5 and part of the transition from DOD to FAA and the differences in the 02/03 versions is the addition of newer materials more than corrections of old material.

Notes on copyright

Copyright law is murky and the government of the people, by the corporations, for the corporations has made some changes that are in violation of the public interest by perputually renewing copyrights. In the US, books published before 1923 are public domain. Books published before 1964 may be in the public domain if not renewed. Books published before 1989 that did not have a (proper) copyright notice "Copyright 9999 by xxxx xxxx; All Rights Reserved" are also probably public domain. Note, however, that these apply to books originally published in the US; if it was originally published in another country, other rules may apply. US Government publications are in the public domain.

Copyright laws vary in other countries.

Tips on scanning books

• Some people just don't get it. Putting a copyleft license on a scanned book is a bad idea. The point of having copyrights expire was so they would be available to anyone for any purpose, especially commercial use (there already being loopholes, public libraries, etc. for personal use). Imposing copyright restrictions on your scanned version defeats this purpose. There are lots of legitimate commercial applications. Allowing commercial use in no way prevents free availability and it increases the number of people who can benefit. Commercial use restrictions also interfere with using it in a permissively licensed document or program.
• When converting from scanned image files to postscript files, some programs produce much larger files. For example, sam2p produces files that are 3% of the size of files produced by ImageMagick. By default images in postscript files are uncompressed.
• The program called unpaper could be handy.
• Do not "blow chunks". When you divide a file into lots of smaller pieces, it becomes much harder to search, skim, etc. You can do that in addition to providing a monolithic file but don't do it instead.
• Some programs, such as the software that comes with hp scanners, produces searchable PDFs by removing the original image after OCRing. That makes the file size smaller and the text crisper, but when the ocr screws up, you have a problem.
• you might want to look at djvulibre
• Engauge-digitizer, g3data, DigitizeIt, and spectrascan are used to digitize data in scanned images of plots
• img2pdf "converts a list of images to a single multi-page PDF document". Looks like it does not know how to preserve aspect ratio. tumble is another program.
• Refocus is a plugin for gimp
• Scanning something larger than your scanner? hugin converts multiple images into a single image. Designed for panoramas but I believe it also works on flat images. grunch is a tool that converts partial scans into a larger image.
• tic98 is a ""lossless image compressor for scanned documents"
• After looking at a lot of scanned books, I think a program which adjusts the brightness over the page would be useful. Compute an image histogram for each square inch of page to determine the white and black values and interpolate between.
• Some people unbind books before scanning, which gives nice flat images but damages the book.
• Instead of putting a book on the scanner, you may want to consider removing the cover from the scanner, flipping it upside down, and placing it on top of the book.
• When scanning a book right side up (using a digital camera or putting the scanner on top of the book), you may want to use a labjack to compensate for the different height of the two sides. If you don't have one, you can use a ream of paper and remove sheets as needed.
• A V cradle can be used instead of having the book lie flat; this is easier on the spine and the pages are less curled.
• For high volume scanning, there are special book scanning devices out there including planetary scanners, robotic page turning scanners, flatbed scanners designed to accomodate books hanging over edge, etc.
• m book scanning robot made from legos.
• scan books to files like "page0001.jpg" not "page1.jpg", one sorts nicely, one doesn't.
• gscan2pdf is a GUI front end. Uses scanimage, unpaper, djvulibre, gocr, tesseract, imagemagick, etc.
• Comparison of free OCR pages and scanning at different resolutions. 400dpi -600dpi works best.
• recaptcha is a distributed system for getting humans to help OCR software one word at a time. CAPTCHAs are used to differentiate between humans and spam bots, and people solve 60 million of them a day. They are currently helping digitize internet archive books. They also have a Mailhide program to hide your email address. You can also go to the site and solve words.

Programs mentioned in this section run under free operating systems such as Linux. They may or may not run on proprietary operating systems.
