Ardunio- Educate Me!

Seeing all the wonderful winners that made stuff out of ardunio and other stuff, I figure that I might want to try doing some stuff using them too. Problem is, I have absolutely no idea how parts work, and I would love to have anyone who's willing point me to places that I might be able to learn the basics of circuit boards, wires, leds, motors, soft/hardware, whatever that's simple to read and learn off of. I know there's tons of Instructables that probably might teach me stuff, but I want to have a general idea first before working. Thanks, username252 (profile image below)

Can you point the way to a DIY audience response system?

Audience response systems are invaluable tools in classrooms but I can't afford the $1.2K that companies want me to spend for a pack of 24 units! I've got 35+ students in my class! Background: Electronic audience response systems allows admins to poll a large number of users on a large amount of questions.My students (G9-12), in general, do have (newish) cell phones. (New cell phones, like new tennis shoes, are a status symbol and among even the poorest students I've seen them with new expensive cell phones). Most students do not have wireless enabled laptops/handheld computers/ accessible in the classroom. What's worse is that many school network admins flat deny student access to school's wireless for fear of security/porn/ inappropriate material etc.The open answer/polling time would need to be able to handle responses from a variety of inputs at different times i.e. little Johnny takes a little longer than Janey to answer the question so we can't have to wait for one student to enter their response before the next student. This time delay in fact would nearly defeat the purpose of gathering responses efficiently.I'm very interested in seeing if a blue tooth receiver/software package could handle the polling of 30+ cell phone connections at the same time.Your help in this matter has enormous potential to achieve a Johnny Lee wiiboard like effect on classrooms worldwide.Alternatives: paper pollingAs noted below, paper polling doesn't scale very well. If I'm performing secretarial duties of sorting paper then I'm not doing my job as a manager of a classroom and education. I feel that any teacher that is still pushing worksheets/quizzes/ etc. on paper then that teacher is working too hard and not working smart.IR remotesI've looked at trying to use off the shelf IR devices that could be used as a polling device. I believe the problem is in the IR receiver being able to identify each individual IR device. How to mod an IR so that it only has a unique signature connected to each signal?

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.

Does anyone here have experience with software "College Algebra Solved"?

I'm taking College Algebra online and would really like some help with my homework and tests. I don't have a graphing calculator as the one I need is fairly expensive so I have to do everything by hand which takes FOREVER. Seriously it's the only reason I hate math. So I found this software called College Algebra Solved. It claims to answer the problems and gives a step by step for you as well. The one thing I hate about software like this is you can't demo it before you buy it. I was wondering if anyone here has experience with this software because honestly all I really want is this thing to answer my questions for me with little effort on my part. I know it's lazy but isn't that what technology is for anyways? I mean would you call using the toilet lazy because you don't want to dig a hole in your backyard?

Saul Griffith awarded a MacArthur grant!

Saul Griffith from Squid Labs, Howtoons, Instructables, and other cool companies has been awarded the MacArthur "genius" grant. He gets $500k because he's so genius-y and it couldn't be going to a better guy. Saul Griffith is an inventor whose innovations span industrial design, technology, and science education. Through a variety of endeavors at MIT and as a principal in Squid Labs, Griffith demonstrates his boundless energy for inventing across diverse disciplines in the global public interest. While still a graduate student at MIT, he designed a unique membrane-based molding system that can produce a variety of common lenses from a single pair of flexible molding surfaces. This prototype has the potential to change the economics of corrective lenses in rural and underserved communities around the world and continues to be a major focus of research and development energy at Squid Labs. At MIT, Griffith co-founded Thinkcycle.org, a web community that has produced socially conscious engineering solutions, such as novel household water-treatment systems. Thinkcycle.org is the forerunner of Instructables.com, a remarkable do-it-yourself website driven by user contributions. He is also a creative force behind HowToons, an animated educational resource designed to engage children in hands-on science and engineering projects. Through the spin-off company Potenco, Griffith initiated the project design for a hand-held human-powered generator, which has the potential significantly to improve access to electronic devices such as laptops and water purifiers throughout the world. Though still quite young, he holds several patents in optics, textiles, and nanotechnology. In these engineering ventures as well as others yet to be imagined, Griffith is a prodigy of invention in service of the world community. Saul Griffith received a B.MET.E.

Flashing LED project?

I have undertaken a sign project for my work that involves LEDs flashing in sequence. We are a Fire and EMS education program and want something that is going to grab attention. At first the project was supposed to be just solid burning lights but has been changed. I'm guessing they want something like the old style movie poster chasing lights or alternating flash between 3 sets of LEDs. It's a little more advanced than I had planned and don't know where to start as far as components go. I've already got the switch they want me to use,  it is very similar to a toggle switch but has a safety cap. My sign is a little larger than a standard letter size paper and I'm thinking 10 or 15 lights across the top should look pretty cool. Any suggestions on where to start or what I need?

create hard wired remote garage door opener?

Backstory (feel free to skip) So, my grandparents live in an apartment building and they have to get a daily visit by a nurse for a condition grandma has (it's not going to get away till she passes, so it's not a short-term issue). The apt. building has a big parking lot closed by a remote controlled gate that can only be opened with the transmitter -the tiny one you hook to your keychain-. The nurse gets there by car and it is not possible to leave it on the side of the road so my grandfather is forced to go out, get to the ground floor, walk around the building and open the gate with the remote, this is really time-wasteful so I tried opening the gate from the balcony but the transmitter hasn't got nearly enough juice toget the signal to the receiver, on top of the fact that they're on the wrong side of the building. End Backstory So, I was set on buying something AC powered, with a seriously extended range, that might send the signal there, but could not find anything.  Could any of you educate me on ho to build / mod something like that? thank you all in advance

Good kits?

Off in another thread we were talking about goodkits being a good way to get your feet wet with the practicalities of electronics: how to solder, what the individual bits look like, and so on. I was lamenting the demise of Heathkit - many a engineer in my generation had their first electronics experience putting together one of Heath's kits, using their excellent instructions.So anyway, what kits are available today that offer the hobbyist a "good" and educational building experience? The kits should have good quality PCBs and components, instructions that go far beyond "solder all the components to the board in the places indicated by the silkscreen", and hopefully some amount of theory on how the thing works, and how to troubleshoot it if it's NOT working.I'll recommend:Lady Ada's stuff - I'm not sure I'm wild about online vs printed instructions, but it certainly gives you a good chance to see what you're getting into before you order anything, and it probably permits a higher level of quality in the instructions than it would be cost-effective to have printed.2Dkits Blinkies - a more limited selection, 2dkits specializes in neat little LED badge-like things

New 'ibles

Decided it would be a good idea to offer both sides of the discussion to the lockpick group. I'm hoping (fingers crossed here) that the community is capable of handling this entire group intelligently and maturely. As such, I figure pros and hobbyists alike can benefit not only from the opening and bypassing methods, but from more information about what's being done to prevent such things. All the information here is for educational purposes, and it helps me in my line of work to see what non-commercial solutions there may be. Also, with the shared knowledge here, it's possible we can come up with even better security options. Afterall, part of the job is getting in, another big part is keeping others out. *In my own opinion, the best security option anyone has is to install a decent security system. That way, even when the physical locks fail (I refuse to believe there is a lock that cannot be picked or bypassed), there is still an added security. Besides that, even having the alarm company's sign in your yard/window really is enough to deter most would-be intruders* So, feel free to post methods for getting in, or keeping others out.

Remembering that its a 48 volt pack built from 4x 12volt lead acid 20amp batteries(cells) wired in series thus to stack the voltage and not the amperage.   Now I know amperage is simply a measurement of consumption so I'm guessing that these Yellowtops are way above the usual 20amp's that the veloteq asks for but I'd imagine that shouldn't make much of a difference.  Seeing as I only want to throw on two of these as to not blow way past  the weight restriction on the ebike itself by hitting 48 volts with four of these also to avoid breaking the bank with an 800$ purchase.  Could I not add some sort of transformer to step up the voltage to 48 volts or something like this? Any suggestions are welcome but I can't imagine this would really be all that bad of an idea.  I'd imagine it should boost the range somewhat if not a fair bit.  I'd imagine that my assumptions here are not far off but I'm here to either be validated or corrected. Or even educated if someone has any suggestions or advice.
