Ten years ago, over a hot 4th of July weekend, a few of us “alpha geeks” were hanging out on Rob Flickenger‘s porch in Sebastopol, CA testing out homebrew microwave antennas when we stumbled upon the fact that you could squeeze about 12db out of an empty Pringles can and some miscellaneous hardware. At the […]
MAKE subscriber Uros wrote to us to share the projects by some of the students in ENSCI, a product design school in Paris, France. I especially liked the design of the 3D scanner demonstrated in the video above. The scanner uses a laser pointer moving along a ring-shaped track around an object to find a […]
Ken Kremer built this adjustable iPad stand using MicroRAX, including some of the new hotness hinged connectors the MicroRAX guys were showing off at Maker Faire this May. Very nice!
Based on the work of German quantum physics pioneer, Heinrich Rubens, I designed this flame tube so propane gas inside the tube flows through holes drilled along the top, and flames are then lit above. I send a sound wave into the tube with a loudspeaker at the other end. When the tube is driven at one of its resonance frequencies, flames form a visual standing wave pattern, as you can see in the picture. Vary the pitch and change the volume to get different patters.
Only recently did I find out that you can develop negative film with instant coffee, vitamin C, and washing soda. This homebrew developer has become known as “caffenol” and there are plenty of photographers out there who have used this method in the darkroom. I read up on a few different recipes and tried my […]
As Marc de Vinck’s Arduino 101 video shows, the Memsic 2125 accelerometer makes it easy to add tilt, acceleration, and vibration detection to your next project. It can be used for making balancing robots, game controllers, musical instruments and anything else where force measurement can be used.
Jason Gessner learned how to weld at Milwaukee Makerspace, and his first project were giant jacks made from bolts. He ended up using the jacks in an event in Milwaukee were teams of people ran around the city doing activities. The game only took a couple of minutes when done correctly, but some teams were […]
