    Making a Carbon Fiber Bike frame

    Brano Meres created his own carbon fiber bike frame after being inspired by one made by Damon Rinard. He has some very interesting pictures of the whole process on his site. I particularly like the frame jig he created out of wood to hold the foam base material.

    Everything began after I read the article "How I Made a Carbon Fiber Bike in My Garage" by Damon Rinard. Thanks to this excellent article, I decided to make a MTB frame, even though I've never dealt with carbon composites before (except carbon brakeboosters I made for my bike long ago). I always wanted to own this kind of frame.

    DIY Jib Arm, Boom or Crane

    Joren wrote a nice how-to on his experience building a jib arm. I am not sure of the technical name for this device, and neither is Joren, but I do know it looks like a good tool to have for any filmmaker.

    I don't know if the proper name is jib arm, boom, or crane. Like everything else in the world, there are at least three names for this. The basis for this design is a four-link system so no matter what the angle of the actual arm is at, the camera "basket," as I call it, is always parallel with the ground. However, I designed a way to tilt the camera up and down, so you can get bird's eye shots that change to be low angle shots, etc. Basically, I tried to anticipate any need I might have of a jib arm and make it as versatile as possible.

    Dress made from food bar wrappers (mostly from airplane granola bars!)

    Paul (project editor @ MAKE) has a friend who sent this in this GREAT dress made from food wrappers, she writes

    ...a dress I made out of food bar wrappers. The dress has won two eco fashion shows (one in San Francisco and one in Chicago). Eighty of the 120+ wrappers on the dress came from a flight I took from Chicago to Munich, where I asked everyone on the plane for their granola bar wrapper (which was given to us for breakfast). When the passengers learned why I was collecting wrappers, they were really enthused and wanted to help me out. What excites me about this food bar wrapper dress is collecting wrappers from people in their everyday life... on a flight, watching a movie, going to a baseball game.

    More pictures after the jump!

    "Peggy," - A Light emitting pegboard display

    Evil Mad Scientist Laboratories have released "Peggy" this is a great open source hardware project for LED art makers! -

    With all the cool things that you can do with LEDs today, there is still one thing that's lacking: simplicity. If you want to run a bunch of LEDs at a time, you usually end up spending a fair bit of time worrying about series and parallel combinations, matching brightness, and picking load resistors. Or, if you're a beginner, maybe you only get one third of the way through the previous sentence-- wondering if you're already in over your head.

    Suppose that you want to make a big LED display for your window or wall: maybe it's your logo, a symbol, your favorite 8-bit character, or maybe even a sign that spells out words like "OPEN" or "ON AIR." How do you go about it? The usual DIY solution involves drilling holes in a panel to fit your LEDs, then spending a heck of a lot of time wiring everything up-- ending up with one resistor per LED (and a three-dimensional mess if you happen to look at the back side of the panel). And, if you do everything in the most obvious ways, it can even end up consuming a surprising amount of power.

    While I have certainly spent my share of time constructing things with the aforementioned technique, at some point it becomes clear that there has to be a better way. In this day and age, shouldn't LEDs be about as difficult to play with as, say, a Lite Bright? Today we are releasing a new open-source hardware and software design that takes some of the sting, complexity, and mess out of playing with LEDs. It's a versatile and powerful light-emitting pegboard that lets you efficiently drive hundreds of LEDs in whatever configuration you like, without so much as calculating a single load resistor.
