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.

Tech Shop

Anyone else out there use/go to the Tech Shop in Menlo Park? I've taken 3 of their safty and basic usage classes for the lathe, mill and aluminum sand casting. I want to start making things, but I'm still a little unsure of myself. For a first project I want to make a vise. I found some plans that I want to scale down a little. I will need to either by or make a lead screw. I'll probably try to make one, its a learning experience, so what's the point otherwise? Anyone there have advise?

Tech space canada

Hello everybody, I was just wondering who would be interested in a tech shop/ space starting in Alberta, Canada. I live there and am looking to start a business possibly just looking for interest. It would include metalworking ie water jet and lathe work, woodworking ie table saw band saw and router, 3d printing and cad design team, laser cutting with its own team, teaching about coding and Arduino and micro controllers. If you are interested comment below. Also, anyone interested in funding a kick starter comment too :)

Parallella a new tech

Hey everyone I know this is new technology that could be very promising but it needs help. 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.

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...)

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

Cen-Tech Thermometer to PC Hacking

I just got my new $30 Cen-Tech thermometer from Harbor Freight and it's begging to be hacked. I would love to be able to use this thermometer as part of a closed loop system to control a hot plate for soldering purposes. Just inside the battery compartment is a header with four pins. They nicely labeled the pins on the silk screen. I'm probing on "Gnd" and "Tx" pins. I used a MAX232 level shifter to convert the TTL output to RS232 so I could connect to my PC. I then ran the attached simply Python app that dumps the data packets to the console. Each packet has 25 characters and repeats at about 3Hz. My question is, how would one go about decoding the data packets? Some numbers seem constant while other move. I'm hoping the data format is obvious to someone. Note, the reading on the display was around 68.8 degrees F when this data was collected. The readings did jump plus/minus a few tenths while collecting. Any ideas?

Physics - Tech engineering software, that is fun?

Hi, Just a quick question... I ran across something called Gmod, or Garry's mod software today by accident. This one here...;=related It looks pretty neat, sort of a mechanical play thing. But, I'm not sure how true to reality the software is, also you apparently need to own a main platform software to use it, like Half Life. I don't have any of the games needed to play around with Gmod. I started to wonder if there is any other software out there that works as an, across the board experimenter's virtual lab? Sort of a mechanical, electronics virtual plaything? I'd think that engineering tech schools would have software such as this, (CAD comes to mind) but I didn't quite find what I was looking for with a google search... Not exactly sure what the best search term would be for something like this? I've come across virtual electronics software, but maybe I'm asking too much for a multi electro-mechanical environment. Has anyone ever used software like this, particularly something fun to play around with, without being to dry? Free would be nice as well, but I'm probably pushing the envelope there a bit! LOL.

tech noob question on stereo jack

Can I have a silly technical question for which I would have known the answer if I only paid more attention at school? how is possible that stereo headphones, ie 2 speaker circuits use only 3 cables? I understand the "ground" is the one that both speakers,ie left and right have in common but how come it doesnt bother the signals which go to the speakers? doesnt the left signal get mixed up with the right signal? and why is it called "ground" when it's not actually connected to the ground, like for example lightning conductor is? I've read through the wikipedia article about TRS several times but still can't understand it. thanks for answer, I promis I won't forget it this time :)
