We have a lot of LCD projectors at school.As you may, or may not, know, they work by splitting the light from a bulb into three beams, shinging them through three different-coloured LCD filters and them re-combining the beams to form a full-colour image on the screen.One of our projectors developed an odd blotch in the image, and a few minutes' furtle by our IT technician found that one of the LCD filters had packed up - the layers had delaminated slightly.Cost of a brand-new projector - 465GBP.Care to guess the price of a replacement LCD unit?

What's the best way to measure High voltage (I think my output is somewhere between 10kv and 50 kv)? Is there a formula for the spark length and humidity (I can measure humidity)? I need to buy an appropriate capacitor for my tesla coil, my initial HV is from an ignition coil.

Inspired by the Illuminato Arduino clone (can't really say clone because it's so much better!) really wants me to create my own Arduino clone. I've been thinking of making a clone for the Arduino Mega, but it'd need so feature that the original Arduino can't offer (like the boarduino is breadboard compatible, Sanguino has way more pins, Illuminato is the most beautiful PCB I've ever seen and has a lot of I/O's). So, I'm asking you guys! What features would you want in an arduino? If this "new" arduino is so much better than any other existing one I'll make kits (if the majority is through hole) for people to buy (no more than 40 dollars, probably, the 65 dollar price tag is a real turn off for the Mega) or just assembled if the majority is smd. Also instructable :P

Whenever you want to finish a prototype, what kind of checklist do you go thru? things like: How do you decide what case design to use, what materials for that same case, how to solder everything up, what makes you decide if you "lock" the Arduino on that project forever by soldering everything around it. If you decide to make it modular, what techniques do you use. What kind of material do you use to attach everything together: Hot glue? close everything down with screws, nails, staples (...)? How would you make it water-proof or make the project resistant to the weather (if it was something to be outside for a long time). If you have to use a lot of cable, is there any good pratice you would suggest? When do you use connectors and what kind of connectors do you use? I would love to see a video tutorial on how to properly finish up a project, and make it look beautiful inside a case. :) Thank you all.

My friends and I are attempting to lucid dream. I don't wanna die and I'm sure my friends don't wanna die and I've heard mixed things. So is it Myth or Fact? UPDATE: Thanks for all the answers guys! I just realized how dumb of a question it was after reading a post that said Even if someone died in a dream and actually died they wouldn't live to tell the tale. Again thanks for the answers!

If certified in CPR are you required to help in an emergency situation? And if you don't can you be sued? Answered
I am considering CPR certification and I am aware of the "Good Samaritan Law" that protects you from lawsuits for trying to help a victim and failing to save their life. My concern is, are you bound by the law to help in every emergency situation that arises? If I choose not to intervene are there legal ramifications?

I've decided to call my company electroni-C, see more in the market place for more info on that, and I'm post this here in the Tech section cause to be quite honest nobody looks at the marketplace.I've decided to outsource the PCBs for kits to another company cause my CNC machine is taking longer than I thought (thing after thing just keeps going wrong!)anyways, I'm running low on cash, so I've decided to go onto phase 2 and start selling kits, but I just want to hear ideas of what people want.examples of succesful kits:TV-B-GONEBoarduinovarious arduino clonesmintyboostbasically everything made by ladyada, lolin shortif you have any ideas for a kit please post.If I decide to go with your idea I will give the idea's creator a couple of kits for free (for you and some friends to make)BTW it can be just an idea, no schematics or anything needed.so if you are a beginner at electronics just fire off ideasEDIT: DEADLINE: August First

Is there any arduino libraries for shfiting the pitch of audio? I'd like to make something like http://hackaday.com/2011/03/17/pitch-shifter-makes-your-band-sing-higher/ but I'm not sure if I can with arduino. I don't need all the code, just a guide as to what library to use. Thanks!

So I was browsing the contests and found an instructable that seemed kinda suspicious. The instructable itself was fine, but in the comments section I found about 8 users, all praising this "amazing", "genius" instructable, and when I checked the accounts, they were all made and favorited and commented on the post on the same day, and that was all of their activity. Oh yeah, the author also commented. I'm also guessing that they all voted as well. My question is, will this be overlooked, or will this author win possibly runner-up with their instructable for cheating? I hope that this will be noticed and will be thoroughly checked. Thanks,Zakbobdop

I am linux (arch linux) user so the question is aimed mostly at linux users. but i'd like to see what windows and other os users think toowe all need sometimes to log in to the computer as administrator (called root in linux) to do maintenance and other tasksin modern os we have some options. we can log in to the entire desktop or console as administrator and work freely. or we can run the single apps we need with 'run as administrator' from our user desktop. maybe we work all the time as administrators (even to surf the net) and then there is no question at allin the world of linux many users dont recommend logging it to the desktop as administrator. i dont understand why. i think based on the following assumptionsi am less likely to smash something when i see it. so i prefer to do stuff in the desktop and not in the consoleif i smash the os i can just format and install it again quickly. if i smash any of my files in home (home is like my documents in windows) i can never recover it again. and i have permission to smash my files when i am normal user tooi trust my applications to not format my drive on their own decisioni log in as administrator to the desktop when i need to manage and as user in other timeswhat way of getting administrator access you use ? why ?

I was on youtube and ran across a video with Diane Eng (I love her fashion technoloy work!) doing an interview and in that interview she was wearing a shirt that the LEDs would light up when anyone spoke. I've never heard of any kind of technology like that and wondered if anyone on here had. If so can you please explain to me what it is and how it works. Thanks! Here's the video I was talking about: http://www.youtube.com/watch?v=A6PfWLc7YhI

Let's say that you have an idea for making a videogame. You are good with 3D software, designing, game flow, you are creative, and you are a programming GOD. What woud you dream game be? Would it be a simple arcade or a puzzle game? Or would it be a complex RPG or action game? Would it have a story? Are you even working on it now? Do you have artwork or ideas you wish to share? Remember-it is your dream game. It's whatever you want it to be.

This will humiliate people who make mistakes so badly. This is a website which googles something for you automatically in a short animation. Good old internet memes! You just copy the url into a new window, and change the ending to what you want to search for.http://lmgtfy.com/?q=Example+searchIt's so fun!

You know when you are signed up on a site and getting friends to visit it gets you points to download stuff?
I'm registered on Tekken.com/tournament, an official site promoting the upcoming fighting game for PS3 and 360, Tekken 6. Every week the site pits two characters against each other and in order to vote for one, you need to share a video trailer link with your friends. Whether it be through IM or myspace, anything will work as long as they click it. Every different friend who clicks your link counts as a point towards your account. Get enough "shares" and you'll be able to download exclusive wallpaper, character PDFs, etc. So i was wondering how these sites work, if there are ways to boost or speed up the process of getting "clicks". Any help would be great.
