Google SketchUp

Google SketchUp is FREE downloadable 3D modeling software that is easy to learn and fun to use. Google information says it has been used by architectural and engineering professionals for years, which indicates that it is powerful enough for high school engineering classes working on a low budget. I can testify from personal experience that middle school students, working through the provided tutorial, can gain quite enough proficiency to create their own designs.

Its use is not limited to architectural design. English/language arts students can create drawings of structures or locales which are a part of books or stories they are studying. History students could sketch the layout of a town or portion of a town which is part of a critical event, or of historic structures like the Great Pyramids. Geometry students could create polygons or polyhedra.

If you want more (and better) ideas, 3DVinci has a free teachers guide with design projects organized by grade (1-5, 6-9, 10-12) and subject (art, gography, history, math, and science). 3DVinci also sells project books: ModelMetrics books teach 3D design  and modeling skills for grades 3-9, GeomeTricks books teach 2D and 3D math and geometry concepts for grades 6-12, and the Google SketchUp Student Workbook uses design projects to teach all of SketchUp's tools and features to students in grade 9 through higher education.

DVD Ripping

I had occasion to extract video clips from an unprotected, copyright-free DVD a couple of weeks ago, and I found a simple, FREE program which fit my needs. Knowing teachers in particular might find it useful sometimes to pull clips for classroom use, I thought I'd share it here.

I looked at several options, but the one I ended up using because of its simplicity was bitRipper. As you can see from the screen shot at left, it has a minimalist interface. Most of us would never need to make any changes to the settings, but I did expand the Settings window for the image; otherwise, you work only with the smaller window. Those of you who, unlike me, know what you're doing, or who like to experiment, have the option of making some more advanced options about your output. I used bitRipper without making any changes to the default settings and had excellent results.

You choose your video clip by chapter from a drop-down list. Without titles, that can be a little tricky; however, I could choose mine from this DVD by its length. The video is converted to an AVI format and saved to your hard drive...and it's ready to play on your Windows computer. It really couldn't be any simpler!

I also found WinX Free DVD Ripper, which has additional functions. I didn't need any of these at the time, but I will keep it in mind for use if and when I do. This one will rip and convert to not only AVI, but also MP4, H.264, FLV, WMV, MPEG, MOV, or other popular video formats. It also gives the option of separating the audio from the DVD video, saving it as an MP3 file. It also supports capturing pictures from the video through screenshots.

If you want to insert the video in a PowerPoint presentation, the 2007 version will accept the following formats: ASF, AVI, MGP, MPET, or WMV.

Extensive List of Free Tools

This amazing list from 21st Century Lit is a great first stop when looking for technology tools for the classroom. Some on the list are online tools, and some are downloadable software. Categories include blogs, graphic design, comics/animation/storytelling, media presentation, information visualization, collaboration tools, audio, and more. I am familiar with or have used several of these, but this gives me lots of new ones to investigate!

System Nucleus

Image source: spencerebus.com
THIS UTILITY AND THE COMPANY WEBSITE ARE NO LONGER AVAILABLE (Added August 2013)

This is a little different from my normal posts, which are about simple little things. Many people I know would think this more advanced than they would be interested in, but I suspect many others would find it very useful.


System Nucleus is a FREEWARE utility for viewing, editing and managing system resources and settings.
It makes these types of tasks much easier than remembering the right command, and allows batch processing of tasks such as uninstalling multiple programs or stopping multiple processes. You can get an idea of its functions from the image above (from lifehacker.com), but for more details check the spencerebus website.

To make it even better, you don't have to use an installed version; System Nucleus has a portable version as well.

I will be trying this one out soon on my "old" computer to delete installation data left over from programs previously uninstalled, and I WILL make a system backup before doing so!

AM-DeadLink

Even if you keep them organized, if you've collected bookmarks over a long period of time you will possibly have some duplicates and probably have several that no longer work. AM-DeadLink is FREE software (Windows only), recommended by Kim Komando, which will find duplicates in your browser bookmarks and text files. You can then verify and delete them. It works with IE, Firefox, Opera, Chrome, HTML, and URLs from tab- or comma-delimited files.

As a bonus, you can also download FavIcons for your IE or Opera Favorites.

Format Factory

This is sofware I will definitely use. We recently needed to convert some MP4 files to WMV, and one of our teachers told us about Format Factory, FREEWARE multipurpose file conversion software for Windows. I tried it out, and it's great. Its functions (copied from the website) are:

  • All to MP4/3GP/MPG/AVI/WMV/FLV/SWF.
  • All to MP3/WMA/AMR/OGG/AAC/WAV.
  • All to JPG/BMP/PNG/TIF/ICO/GIF/TGA.
  • Rip DVD to video file, Rip Music CD to audio file.
  • MP4 files support iPod/iPhone/PSP/BlackBerry format.
  • Supports RMVB,Watermark, AV Mux
Thanks, Marcus, for sharing this one. It's going to prove useful for several projects I have in mind.

GIMP

I'm always on the lookout for FREE alternatives to expensive software. While Photoshop is probalby the best-known photo editing software package, with incredible features and results, its pricetag is a little high--well, extremely high--for the average user. I do appreciate the features in Irfanview, which I have used for years, but sometimes I need--well, want--more advanced options. I have found GIMP (GNU Image Manipulation Program) to be a viable alternative for those times when a little more power is needed.

GIMP is not for the faint-hearted. Any software which can accomplish a wide variety of more complicated operations such as this will not be as easy to learn as simple word processing software. It does have built-in help, and a user manual is available for downloading. The GIMP website offers tutorials for various levels of expertise, and a Google search for "GIMP tutorials" yields even more. Perusing a few of those will give some idea of the amazing finished products which can be produced.

Oh, and for those of you who use portable apps, try GIMP Portable for your on-the-go photo editing.

GIMP is freeware, but of course you are encouraged to make a donation if you like the software.

Mobipocket Reader

First, why elecronic books (eBooks)? This is just one more way to give people access to books. Many younger people are more used to looking at a computer screen, or certainly to an iPod or iPhone screen than at the pages of a book. While I happen to enjoy the feel of a book in my hand, reading from printed text, there are times when I find myself in a “waiting” situation without a book. I always, though, have my PDA, and I enjoy having a book waiting for me there. There are many reasons an individual might be interested in eBooks and eBook readers.

Amazon has its Kindle, and there are other devices available which I have not researched, but I am always interested in FREE options. Mobipocket Reader is a flexible FREE program available for the desktop and a number of mobile devices* which lets you “build, organize, read and annotate your entire eBook library” and  The reader is not a simple text reader, but can display graphics as well. Some books, such as Dorothy and the Wizard of Oz by L. Frank Baum I’m reading, include the illustrations from the original edition. Others, like Thornton W. Burgess’s Adventures of Reddy Fox are text only. In addition to eBooks, Mobipocket also can manage RSS feeds.

Downloading and installing the desktop version is all that is needed. The first time you connect your compatible mobile device, the application will be installed on it.

You can drag and drop .pdf, .txt, .rtf, html, and Microsoft Office files onto the desktop application to convert them.This gives the flexibility of choosing to read some lengthy documents, such as .pdf manuals, in a more comfortable environment or on a mobile device. The .pdf I opened in Mobipocket Reader was much easier to read than the original document, as the text was larger and it was broken into more manageable pages. If you desire, you can also create your own documents using the FREE Mobipocket Creator, inserting images and graphics along with text.

I love that when you select a word or larger piece of text, a menu box appears which will let you add a note, highlight it, copy it, modify it, or add a link to another location in the book. This makes it so easy to annotate and to create bookmarks for text you want to remember or come back to, as any of these actions creates a link at the right of the reading to its particular text. Here's what The Murders in the Rue Morgue looked like when I had finished the first half:



While you can purchase books, some sources make FREE eBooks available. These books, perhaps not so obviously, are those which are free from copyright restrictions. Simply download your selection, choosing to “open” rather than “save,” and the book will open in Mobipocket Reader ready to read, and the file will be saved in your My Documents eBook folder. Sources I’ve found and downloaded from include:
  • Diesel eBook Store (more than a million free eBooks sorted by category; also eBooks for purchase)
  • Project Gutenberg (over 30,000 free electronic books)
  • Manybooks (over 16,000 titles, sorted by title, genre, and author, wide variety of formats)
Wickpedia indicates that the text or personal additions cannot be printed or exported other than by copying and pasting into another application. ABC Palm Converter will convert some .prc files to Word, .txt, .rtf, or other formats. Annotations will not be included in the converted file, and the converter software will work only on REAdTEXt files; It will not convert files that have been converted to .prc files by Mobipocket using the drag and drop method.

This could be useful in classrooms and for students who have a mobile device other than an iPod/iPhone. It would also be useful for students who need larger text.

*”PalmOs, Windows Mobile, Symbian (Series 60, Series 80, 90, UIQ), Blackberry, iLiad (by iRex), Cybook, ... And if you have a Symbian smartphone, an iLiad, or a Cybook, there is a good chance that Mobipocket Reader is already preinstalled!” Source: Mobipocket (I note the list does not include the iPod)

Portable Freeware

Hmmm. What is that??? Funny you should ask. I wondered, too, when I saw it, so I looked it up and found that it might be useful. Here's the definition given by the individual who collected and made available on the web The Portable Freeware Collection (copyright 2004-2007):

  • It must run without installation.
  • It must run on older versions of Windows which might not have been updated.
  • It must not have any coupling with Internet Explorer, audio/video codecs, DirectX etc.
  • It must not write settings to the registry or local filesystem.
  • It must not leave any trace on the host machine at all, even when the app crashes (hereby referred to as "stealth").
  • It must run with guest access rights.
  • It must be able to compensate for USB memory stick drive letter changes.
A further description is available, but this will suffice for here.

Applications include everything from audio (conversion, ediors, iPod managers, players, etc.) to video (authoring, capture, conversion, players, etc.). It's actually a pretty impressive list. I haven't tried any of these yet, but it seems to me they might come in handy when moving around from machine to machine in different locations where you don't know what applications might be available. Having both data and apps on a flash drive sounds pretty cool.

LocatePC

If you travel (or not...I had one stolen from my home!), your computer could be stolen pretty easily. LocatePC from ICONICO is free software that will send you an email message when the thief accesses the internet, giving you the information needed to track down the account used for that internet access. Given my experience, I'll probably install this one. Recommended by Kim Komando, so I trust it completely...well, as completely as I trust anything web related!
