Présentation[modifier | modifier le wikicode] Pourquoi les VP DIY[modifier | modifier le wikicode] Pourquoi se fabriquer un vidéo projecteur DIY (’’Do It Yourself’’) alors qu’on peut en acheter un tout fait dans le commerce ? Prix : Tout d’abord un vidéo projecteur DIY revient bien moins cher, 300 € en moyenne. Les ampoules utilisées ne sont pas les mêmes, nous utilisons des ampoules qui coûtent entre 30 et 45 € et qui durent 10 000 heures. Celles des vidéo projecteurs du commerce coûtent environ 300 € pour 2000 heures.

Telares en cajas Estos telares en cajas de cartón me han robado el corazón. Están en el Museum of Contemporary Craft en Portland pero estoy segura de que pronto tendrán una versión parecida en el colegio de mis hijos. Double Capacity MintyBoost with 4-AA Battery Holder Modification Need a highly portable USB power source that can be replenished with readily available, common batteries? The MintyBoost from adafruit Industries is an awesome little kit that nets you a USB charger that runs on 2 AA batteries. This is a great thing because AA batteries are available anywhere and together with the MintyBoost can be used to power most USB devices when you find yourself in a situation with no other source of power. As a volunteer providing emergency communications for organizations that are deployed to disaster stricken areas I have been in this situation before. Keeping critical communications links operational in the field is a major mission success factor. Having a highly portable source of USB power to keep cell phones working is a valuable tool for the first responder. This charger does more then just provide the 5 volts required to charge USB powered devices. This battery holder modification is the primary subject matter of this instructable.

Making Paper Bricks in India At MAKE we have covered a type of paper brick before, but it was used simply as a fire starter. Professors Rahul Ralegaonkar and Sachin Mandavgane of the Visvesvaraya National Institute of Technology in India (VNIT) have come up with a process to make paper bricks designed for creation instead of destruction. It started when they visited a paper recycling plant in 2009. They learned that 15% of the material that went through the plant was piled up into an unsightly sludge and sent to a landfill. For those not familiar, this is a prime example of one of the perils in recycling as opposed to upcycling. Recycling results in materials being turned into products of a lower quality than their predecessors, while upcycling preserves the quality of the product through many generations. Raleganokar and Mandavgane decided to take some of that sludge back to their lab and play around with it along with students over the summer. Related

Build your own pocket mini computer The Pocket Mini Computer is a small and versatile computer running a full featured BASIC interpreter with 32K of ram. It will work with a standard VGA monitor and PC compatible keyboard. Because the Pocket Mini Computer has its own built in microSD memory card slot and BASIC language you need nothing more to start writing and running BASIC programs. A Wii(TM) compatible gameport as well as stereo audio output create a compelling enviroment to write programs and games. I'm the designer of the Pocket Mini Computer. I wanted to create a product which would give those in the younger generation a chance to see what computing was like in the early days before the PC. The Pocket Mini Computer has been a labor of love from board design to preparing the BASIC programming language. You'll be able to do more than enjoy a simple "HELLO WORLD" program.

DIY Lock Picks I locked myself out of my house the other day... D'oh! It would've been easy enough to break a window, but hey it's my own home. So I decided to try and pick my way in. I used a pair of garden shears to cut up a hose clamp which I used as a pick and tension wrench. Even though it was a very crude piece of work, it did the job! So I decided to polish my impromptu lock picks into something more presentable. Hose clamp DremelSugru Pliers Vice Safety gear Don't have a Dremel? I've entered this into the Spy Contest.

It might be the most convoluted one. I’ve checked and double-checked for errors. If you find one, leave a comment and I’ll fix it as soon as I can. But ‘woven’ is not that difficult to sew once you understand the technique. If you’ve tried the marionette tutorial, then you could sew this bind with that method. A few things to remember: when you are making the first diagonal Xs, do not make the knot too tight. hole pattern sewing pattern EXIT = needle pointed DOWN and ENTER = needle pointed UP=====

David A. Mellis: Fab Speakers These portable speakers are made from laser-cut wood, fabric, veneer, and electronics. They are powered by three AAA batteries and compatible with any standard audio jack (e.g. on an iPhone, iPod, or laptop). The speakers are an experiment in open-source hardware applied to consumer electronics. By making their original design files freely available online, in a way that's easy for others to modify, I hope to encourage people to make and modify them.
