DIY CNC Router Plans : How to Build
NOTE: I originally posted this on my arts and crafts blog, Make It With Jason, and you're welcome to go visit and check out my other tutorials, reviews, and step by step drawing and painting lessons. Ever since I saw my first CNC, I knew I wanted to own one. I'm a realist though, and I also knew that I wouldn't own a REAL $20,000 one. So, on a whim this spring, I decided to design and build a homemade 3-axis Computer Numerical Controlled milling machine myself. I looked all over the web and decided to build one using drawer slides as my rails, an arduino as my microcontroller, and try to keep everything within the $300 mark. So far so good. So, without much ado, I am going to show you the steps I took to build my diy cnc router project (please realize, as of April 16th, 2013, this project isn't quite finished--in fact, it's at the halfway mark). Onto the Instructable!

Quadcopter build log
1. Introduction This page will be a walktrough on the creation of my quadcopter. It will be a quick tour as most basiscs are explained in the 'multicopter basics' document as listed on the right. A list of the items I acquired for the project is in on the bottom of this document. 2. Should you decide to build your own frame, start with drawings as every engineer does. Cross (aluminium square tubes from the local DIY shop) For the Dutch, Hornbach is your next stop ;-) Lower level of the "Hamburger", with light switch, power plug, Spektrum satellite receiver and LiPo low battery warner. 3. I decided to make a 'power ring' to provide the ESC's and other equipment with power. After supplying your ESC's with power, you have to program each ESC to let it function properly for a Quadcopter. Typical programming card Quadcopter setup. 4. Before you make your control board unreachable by wiring etc, be sure it's programmed with the latest firmware. Pin 1 on the KK board is located here: 5. 6. !! 7.

How to Make a Three-Pendulum Rotary Harmonograph
A harmonograph is a mechanical device that uses swinging pendulums to draw pictures, believed to be originally invented in 1844 by Scottish mathematician Hugh Blackburn. This 3-pendulum rotary type of harmonograph gives a wide variety of pleasant results, and is fairly easy to build once you've settled on a design and have acquired the appropriate materials and tools. This is a great project to do with kids and can result in endless experiments creating new types of geometric designs. Skip to More Results and Movie Two lateral pendulums swing back and forth at right angles to each other with arms connecting to a pen.
'Drone It Yourself' Lets You Create a Drone from Any Object
Have you ever wished for a flying book? A flying keyboard? Or, perhaps, a flying bodyboard? Well, it's your lucky day, because thanks to "Drone It Yourself," you can turn pretty much any object into a quadrocopter. The drone kit, created by Dutch independent designer Jasper Van Loenen, is comprised of pieces that can be 3D printed, and then clamped to any object you so desire. All that's needed are the control unit and four propellers, and then you can make virtually anything airborne. On his website, Van Loenen points out that the parts can be custom-designed, and that other DIY enthusiasts can modify them to make new add-ons for the quadrocopter drone.

Build a Touchless 3D Tracking Interface with Everyday Materials
Combine low-tech materials with some high-tech components and build a completely Touchless 3D Tracking Interface. Explore capacitive sensing by using several panels of cardboard lined with aluminum foil. These panels, when charged, create electric fields that correspond to X, Y, and Z axes to create a 3D cube. With the aid of an Arduino microcontroller and some supplied code, movements inside the cube are tracked as your hand moves around inside the field. For Weekend Projects makers looking for an introduction to Arduino, this is a great project to learn from. Once your touchless 3D tracker is up and running, what you do with it is only limited by your own imagination! Make an RGB or HSB color pickerControl video or music parameters; sequence a beat or melodyLarge, slightly bent surface with multiple plates + a projector = “Minority Report” interface More: See all of the Weekend Projects posts Related
DIY Polygraph Machine: Detect Lies with Tin Foil, Wire and Arduino
DIY Polygraph Machine: Detect Lies with Tin Foil, Wire and Arduino Lying is awesome. From a very young age, children learn that flat out denying the truth gets you out of trouble and helps keep you calm in the face of horror. If you're industrious and don't have the dough for a legit polygraph, you can make your very own galvanic skin response (GSR) device. Today, we will make a cheap GSR device and learn if our toothbrush is really safe after all. Materials ArduinoAluminum foilVelcroWire10k resistorBreadboard Step 1 Make the Electrodes GSR machines require an even and consistent connection to the skin in order to function properly. Begin by taping the exposed end of a wires to a sheet of foil. Adhere a strip of Velcro over the tape and cut off the extra foil. Last, add a single piece of Velcro at the end of the foil side. Now you have an electrode that wraps perfectly around your finger. Step 2 Wire the Circuit Wire the circuit according to the diagram below. Step 3 Load the Code See Also
