Rotating 2D into 3D

Playing around with making a 3D shape from layers of cardboard. This is a 2D image rotated 180 degrees and then built with 60 layers of laser-cut cardboard. Forgot to document this one so it's in the forum.

remote control outside light

I am not only a newbe but also electrically challenged! I will explain what I would like to do and see if anybody can help me. I am a hunting guide in Illinois and I have to take hunters to thier stands in the morning before it gets light out. I walk them to the tree and then return to get them later in the day. I would like to attach a small light to the stand that I could control from about 50 yards away and maybe as far as 100 yards away with a remote control. I would like it to be small and attach with a magnet possibly and hopefully be waterproof. I want to keep the cost down because I have about 40 stands on this property and the one I saw at Cabellas is about $40.00 Here is the link to that product:;jsessionid=XACUKMQYMAZHOCWQNWRSCNYK0BW0IIWE?id=0026451416653a&type;=product&cmCat;=search&returnPage;=search-results1.jsp&QueryText;=remote+control+light+for+stands&N;=4887&Ntk;=Products&Ntx;=mode+matchall&Nty;=1&Ntt;=remote+control+light+for+stands&noImage;=0&_requestid=7662 I like the LED thing they have going. Any thoughts?

Potential Instructable - Automatic Security Cam for your Macbook

I saw this on the Make blog and thought it would make a good Instructable. Anyone up for the challenge? It seems like most of the information is there in the comments:"This came out a few months ago, but I just found this on Flickr while researching the upcoming weekend project. It's a way of automating your isight to take a picture 60 seconds after you, or anyone, open it up. Flickr member omegastation set this up before sending off his macbook for fixing. In a worst case scenario, if someone stole your macbook, you could have your macbook send you pictures of them.I set this up and I made this little automator program that takes and sends the pictures, but I don't have a lot of experience programming from a terminal and I got hung up on step 5. If someone could make a little screencast of how to set this up, that would be awesome. This seems like it would be a simple first programming project!Update: Check the comments for super explicit instructions... with these instructions, anyone can program this now! Thanks Omegastation!

Make water balloons explode in mid-air

Hello to all, This is my first post, so if I make a mistake I apologize in advance. I am looking for a way to make water balloons explode in mid-air. It must be safe (i.e. I am not going to shoot them out of the sky with some sort of projectile) and I would prefer not to utilize some form of explosive device. I would prefer something I could time and continuously reproduce. Whether it be an apparatus or a chemical reaction. It has to be safe to be done around children, environmentally friendly, in other words I don't want to cause anyone or anything harm other than the balloon itself. I would like to be able to make the balloons burst at either a specific time after launching or throwing or have them burst after reaching a certain height in the air. If I can figure out a way to this I will gladly share my whole idea. Thanks in advance.

Cell Phone Repair?

Recently my girlfriends cell phone broke. The On/Off button still works, but none of the other buttons work. It still can receives phone calls, and text messages, but only one button works. The other day a couple of the other buttons worked briefly, but they went back to not working after a couple of minutes. I think its a problem in the phones wiring. Before I go opening up the cell phone, I was wondering if anyone has any advise or any experience working with cell phones, that might be helpful.

question/advice on led

I'm wanting to externally light my lcd screen on my metal detector for late evening use. There is no room to do it internally. I think I would need two leds for enough light probably. I am gonna add a small plastic box on the top of the lip/sunshade that sticks out above the lcd screen and have the led/s going out the bottom of the box and through hole/s drilled through the lip/sunshade. I'd like to have a small push button toggle switch on top of the box to turn the leds off/on. I saw some leds at radio shack that was already in a housing with a built in resistor, not sure what size though. I'm new to leds, I've read a tutorial on them and understand the basics, the main question for now is what color leds would probably be best to do this? I was thinking that white may glare too much, the lcd screen has a thin clear protective screen over it as seen in the pic with the item identification symbols, depth,sensitivity etc. Hope somebody can help with the led color that would probably work best, first of all. Then I'll go from there. I'm going to radio shack today to see if they know what they're talking about when it comes to my project,doubtful, lol. Oh, and the detector uses 4 AA batts(6V)...obviously. I'll check back later to see if anybody has any recommendations that may help me out. Thanks!!!!!

Plasma Arc Waste Disposal

I was watching the local news earlier... and they started talking about a new waste plant being built in Ft. Pierce, Florida.Basically, they vaporize the trash and sewage sludge under a vacuum, and use the by product gases as fuel for the plant and power turbines. Steam is going to power a local juice plant. Solid by product (rocks and such) can be used for construction etc.On top of that, the by product gas - when burned - is cleaner than burning natural gas or garbage. Even if you think climate change is a myth, I think you can appreciate cleaner air to breath :P This plant is going to eat up the local landfills too :)I just thought it was pretty cool. This is the first plant in the United States and the third in the world (other two are in Japan and are much smaller).Comments?

Looking To Pick Your Skilled Brains

Advice on best how to make a piezometer out of readily available hardware store parts without use of any power tools and access to only a very few hand tools. Basically a piezometer is a clear, straight plastic tube that you attach to the outside of (in my case) a plastic 250 Liter rain barrel (about 1.5 feet diameter, 4 feet high) from top to bottom. The top is exposed to the open air, while the bottom feeds into the bottom of the barrel (by going through the side very close to the bottom). It needs to have a diameter of about 1/2 inch, be very solid, straight and secure, and a 'water level mark' must be etchable in it somehow to indicate the normal level of water inside the barrel when the barrel is full (full means a few inches before the absolute rim of the barrel). The barrel is filled with gravel at the bottom, sand on top, and enough room for a 12" waterhead above the sand. I'm using it as a slow sand filter (SSF). The idea is that the pressure of water at the bottom of the barrel fills the tube up to the watermark against the action of the atmospheric pressure forcing the level in the tube down below the watermark. When the level of the water in the tube is about 15 inches below the water mark, it means the water pressure at the bottom of the barrel has decreased to the point where the sand in it needs to be cleaned (no water getting through). Any ideas will be greatly rewarded in the afterlife. Thanks!

How can i keep my attic warm on a small budget?

I live in my attic year round. its managable, however when the overhead stars are open, it sucks the heat from the rest of the house. I live in a VERY old house (still bark on the beams) with a metal roof but no insulation in the attic. i would love to not have to put in insulation and finish the ceiling (sheet rock etc.) because it would be costly and make it unhospitable in the summer. I was hopeing that someone out there had a very cool method for keeping some heat in, or creating cheap heat easily. the rouble is that all the heat simply goes out the roof, so space heaters wont work. thank you very muxh for your help! ~farley

Recursive Food

I've been thinking about the concept of recursive food for Thanksgiving, as epitomized by the Turducken (bird inside a bird inside a bird.) While we don't have time to make a Turducken for our crowd this Thanksgiving, I'd like have something equally cool in concept, but less time-consuming to create. Suggestions? Also, is it possible to make recursive food that doesn't end up looking like a Katamari Damancy-style foodball?Having a collaborative/pitch-in dinner party where everyone must bring some sort of recursive food is also sounding like fun.
