How to make your own Enigma Machine?

Hi, I've got an old typewriter that still works wonderfully. Now, not being a big typewriter 'enthusiast', I still have a fair amount of fun using one. It's a manual typewriter, and I was wondering if it would be possible to get a separate set of arms made, with symbols corresponding to the keys. Essentially, my very own Enigma Machine, except it's my own code. Think any of you guys can help me out?

My complete ball tower showcase

Just figured I'd post the images of all my ball machines (at least the ones I HAVE images of, mind you :D)Click on the pictures to see details of them.Fun Facts:-Although Enigma was much larger than Dynamo, it took half as long to build.-On Dynamo, the part with the Flexi-Tube and Ferris Wheel was initially a Maze (or, as I call it, a Ribcage). Due to balls having trouble making it through, I decided to replace it.-On Enigma, I had initially planned it to be two 8-foot-tall towers. Unfortunately, with all the elements I wanted to put in, I had to alter my design to make them all fit.-Both of the two machines have at least two loops on them and a spiral bowl.-The red staircase in Enigma goes across the machine instead of from one tower to another one adjacent to it.-Both machines have seven path separators.EDIT: New ball machine added.Feel free to comment, and if you want to showcase any ball towers you've built, be my guest.Here are vids:

MIT opens its academic doors to all online

An MIT education is now just a click awayhttp://www.boston.com/news/local/articles/2007/12/01/an_mit_education_is_now_just_a_click_away/Ever wanted to delve a bit deeper into matrix theory, especially vector spaces and the misunderstood twin enigmas of linear algebra known as eigenvalues and eigenvectors?As sure as every square matrix has a determinant, you are not alone. Now there is a kind of cerebral clearinghouse, accessible without ever setting foot inside MIT's hallowed halls, for those so inclined.On Wednesday, the school celebrated the completion of a six-year initiative to put its entire curriculum online, with all 1,800 undergraduate and graduate courses - lectures, readings, labs, even problem sets and exams - available with just a few clicks and a spirit of scientific curiosity.The initiative, the first of its kind, has been enormously successful, so far attracting some 31 million visitors from nearly every country who are drawn to such classes as Electricity and Magnetism, Classical Mechanics, and Introduction to Algorithms.Lectures and readings from MIT's literature and history courses are also online, but the 20 most popular courses all involve science, economics, or math.High school students and teachers are among the most avid participants, with 15,000 accessing the site each month. The Massachusetts Institute of Technology has launched a website, called Highlights for High School, that is tailored to their interests.

Haptic Feedback Meditation (E-Meditation)

Hello, I am a 17 year old electronic hobbyist. I am in the process of making a "Haptic Feedback" meditation device. I give the whole project story here. If you are just interested in the final project you can skim or skip to the "Testing" section. THE IDEA Many months ago (when i was not so knowledgeable about electronics) I had an idea. I wanted to be able to see my thoughts as I thought them. I was obsessed with the idea of this and the thought of what would happen( imagine holding up a microphone to a pair of speakers). I could imagine myself staring at my own thoughts (or a colorful representation of them) for hours. I imagined it to be a "New Generation" of meditation. I drew up a few sketches of what this would look like and.. I hit a wall. At the time. I knew absolutely no way to do this. I just knew it was possible. I put the project on the back burner. CONSTRUCTION Six months passed and I had gotten better and better at electronics and micro-controllers and such. A month ago, I started obsessing over it again. I did some internet searches about this type of technology and all the gibberish started making sense. Not before long. I had ordered the parts for it. It cost me a good 100 dollars in birthday money. But it was well worth it and i do not regret the purchase's at all. The three main pieces were a Micro-controller(arduion uno), a brain-wave reading headset(from an expensive childs toy) and a 7 inch by 3 inch RGB led panel( a fancy panel that makes different colors and patterns). Despite knowing a little bit about electronics I was out of my depth, yet still addicted to the project. Long story longer, I had tested the three pieces of technology and they all worked beautifully. With my limited supplies i busted open the headset, made some solder joints, plugged it into the micro-controller, plugged the micro-controller into the computer, and plugged the brain reader into me. Someone before me had already made sample brain viewing  programs in the processing language for these kinds of projects and i downloaded it. I turned on the program and flinched as i turned on the headset( being plugged into your laptops battery can be a tad unnerving). I was looking at a graph of my brainwaves in a system of line graphs and bars. TESTING This was exciting stuff. I sat there for perhaps an hour just staring at my brainwaves shortly noticing a pattern emerging from just simply staring at even the brain reading program. I noticed the more I stared at my brainwaves looking for the next sudden jump or dip. The less they did. In other words, actively TRYING to move my brainwaves, almost completely nullified them. This was very interesting. I took the device and my laptop to my school To get an accurate sample, I allowed any and everyone who wanted plug themselves in to go right ahead. As they messed with thier hair to get it to fit right and turned it on. What was seen for a few seconds was a (what I consider healthy) measure of brain activity. Everything was jumping up and down at varying levels. But after the subject began staring at this dance. The brain activity shrank and shrank until little was left to be observed. Occasionally depending on the situation the subject would then get bored with the lack of activity and try and make some sort of small talk. It then showed a small rising in overall brainwaves that was immediately crushed by the subjects attention toward the screen. In the initial planning, this was the last possibility I had considered. With accidental electrocution being higher on my list of possibilities. The grandiose plan of mixing my thoughts and ideas in front of my eyes shrank. I was loving every second of it. I then later plugged the panel into the device and began writing code to make it react the way i wanted it to. I had programmed the panel to display the color blue when meditation was high and red when attention was high. Purple would occur during a balance of the two. I then took out my computer from the equation as a reader and decided to see what would happen by just watching these two stats work themselves out on a color panel. I got similar results. When I was actively attempting to meditate while simultaneously watching my level of meditation it was an unwavering red. Deep breaths and glances away from the panel would bring purple to blue colors. Then I tried something completely different. I attempted to radiate unconditional love for my brainwaves. I accepted them for their want to be attentive and alert. And embraced them with as much sincerity as I could. The panel turned purple and stayed blue for as long as i could keep this state up without wavering. "Wow" i remember remarking. I may have created the worlds first "Unconditional Love bench press". And your up to speed. FUTURE I have some ideas for the future of this project but I have caught myself in a mental enigma. How would one meditate to the thoughts of their meditation without their monitoring of the brainwaves getting in the way? Or have I missed the point of meditation which might be to have no thoughts? Ideas and suggestions would be great. I would love to hear what this community would have to offer to this device. Input on meditation? Input on the technical stuff? All is welcome.
