Tech Day

3/26/2008 is tech day at my school. There are going to be lots of exhibits of robots, etc. in the library. I was thinking about making some stuff for it, but I can't think of anything. Can you guys give me any ideas, and maybe a few links to Instructables? They all have to be cheap, since I am already working on two VERY expensive projects, and basically have $20 USD of spending money left.Thanks, and MAKE IT FAST!!!!!

Tech - Challenge

A challenge to all Instructables to turn an old amplifier into something new. Possibly combing several of them and rigging up something cool. Should be fun.

Virginia Tech Massacre

I am guessing most of you have heard of the horrible murders that went on this morning at Virginia Tech. For those of you who do not know, just turn on your news network. I was just wondering everybody's thoughts on this horrible case.

TECH WE WANT!

Well in this group, we are all about technology that spies would use and things that would be considered "Spy Stuff". Anything made here doesn't have to be something spies actually use, it could be stuff that you think a spy would use. And please no cans on a string. Cool stuff like laser microphones, and stuff like that, most anything is accepted.

Jobs for the Creative Techs?

I love studying electronics and doing creative things with electricity. I was an artist/musician throughout all of my youth and decided to switch over to creative electronics after discovering the art of circuit bending. I want to get a degree involving creative applications of electricity, but I'm having trouble getting a clear picture of what the job market is going to be like after i graduate. I am wondering what creative positions are available, not just with Instructables but in general. Are there any particular companies that would be good to look into? I'm trying to plan my degree so that it will be appealing to the companies i want to work for. I was an artist before i was a tech/engineer so I'm particularily interested in things such as product design, creative tech projects, animatronics, sculpture and art/music installations. Any advice would be great, I'm eager to find a job that will require my creativity and that isn't mundane. Is creativity something that is reserved to be expressed in my spare time or can it exist within the job market as well?

Parallella a new tech

Hey everyone I know this is new technology that could be very promising but it needs help. http://www.kickstarter.com/projects/adapteva/parallella-a-supercomputer-for-everyone I am not affiliated with this project but I do believe in it. If I had any more money I would increase my pledge but that is beyond my means at this time. So, I'm coming to the community. Just check this product out and spread the word however you can. I personally believe that this could be useful for many applications where an arduino doesn't have enough processing power. Plus this device only requires 5 Watts under full load according to elementary test. And best of all it is set to release at less than $100. With the support of the community we can bring this product to market.

differential amplifier tech

Hello, I'm following a circuit diagram for a current monitor that uses an op-amp as a differential amplifier. Connected to V- and V+ on the amp are the positive and negative leads of a 10mH Inductor that senses the current (as much as 9A) passing through an insulated positive line. The gain on the op amp, I'm told, is 220. If I calculated this correctly then at 9 amps in the insulated wire, 0.09V should be produced by the inductor and there upon entering the V+ lead and -0.09V in the V- lead for a differential of 0.18V which gets amplified to 39.6V. However the voltage source that powers the op amp is only 9V. So question # 1: Did I break down the math correctly? question #2: What happens to the excess voltage from the gain? I am getting all of my op amp information from wikipedia. I've never used an op amp successfully before.

Why Tech Contest disappeared?

On the Instructables site the Tech Contest disappeared. Is it closed, or they won't announce finalist and winners? Or will appear when the winners have been announced? I entered in this contest and even if I'm not a winnner I would like to see the best projects. Thanks for your response!

Tech-tastic Coffee Tables

Coffee tables can really bring a room together, especially if they're high-tech and provide their own entertainment. They're expensive, as the site suggests, but just the ideas warrant personal kudos. Of course, as with any coffee table, you'll need to have a coffee table book about coffee tables.Link via Neatorama

High tech smoke signals

Daniel Schulze is an industrial design student in Berlin who is working on a sweet smoke machine. The plan is to have a 7x7 grid of holes that shoot little clouds of smoke into the air. The smoke comes from a fog machine and is shot up in the air with drivers. Check out the video below to see a test of one row. The full setup will be shown next week at DMY Berlin.

New assistive tech channel?

We're about to break out a new channel for assistive/adaptive tech projects, and other "disability hack" type of Instructables.  The big question:  what do we call this channel, and what category do we sort it under? Why is this a hard question?  Check out the Humana Health by Design contest entries - they include everything from ultra low-tech tools and life hacks to construction projects and full-on techie builds.   Perhaps we need more than one channel.  If so, how should we divide the Instructables?  Do we need one channel for high-tech projects, and one for low-tech?  I've been playing with the ideas of "assistive tech"  for the high-tech/gadget-based projects to be filed under Technology, and "adaptive tools" for the low-tech/reuse projects and life-hacks to be sorted under Living.  These still seem to be arbitrary distinctions, and I'm not sure they make sense.  What do you think?  Please discuss in the comments, or feel free to send me your suggestions by email/PM!

Who are your "Tech Heros?"

When I was young I idolized Jacques-Yves Cousteau, in part because of the undersea technology (aqualung, minisubs, habitations, etc.) but also since he was one of the first to warn of overfishing and open-ocean pollution. Do young people have technology heros today? (Linus T. and Bill G. come to mind, but I was hoping for someone more interesting...)

Low-tech fireworks in China

Out in Naunquan, China the villagers use molten iron to celebrate instead of fireworks. The tradition dates back some 500 years when the blacksmiths of the day couldn't afford fireworks and did this instead. While there's only one color to work with, the effect is pretty stunning and a lot more in-your-face without, you know, melting your face off if you don't get too close.via Gizmodo

Original idea to ask her dad

Hi there, My name is Nicolas, I'm french and i'm asking for the help of the community. Me and my girlfriend are thinking to get married soon and I wanted to find an original way to ask her dad for his permission. The thing is that her parents live in Washington and I'm not able to go there. I was thinking of sending something or make something virtual (i'm a software engieneer).  Moreover her father is not a real techy guy but rather a tech enthousiast. So I search something around the tech theme. So here is my question, do you have any orignal idea with this tech direction in mind that i can produce to ask her father. Sorry for my bad english. If something is unclear, please ask for mor explanation. Best regards, Nicolas
