  1. Ancient CRT monitor revived using an Arduino Uno

    Hacker “MmmmFloorPie’s” senior project in college, in 1989, was a device based on the venerable Motorola 6800 chip that could record and play back sounds. It could also display these recorded waveforms on a monochrome CRT monitor. The monitor in question was purchased as a bare CRT for $20, and mounted in the cardboard box […]
  2. Turn your door into an ‘alien portal’ using Arduino

    As YouTuber Evan Kale puts it, his set is was kind of boring. He decided to spruce things up by turning his ordinary door into an “alien portal,” lining it with a strip of RGB LEDs. Though this may not be the first time you’ve seen this type of lighting in action, he directs our attention to […]
  3. Grow your own salad with this rotating hydroponic system

    You likely know that growing plants via hydroponics involves some sort of water and fertilizer solution. Perhaps, however, you don’t realize that these plants need to be removed from the water occasionally in order to air out the roots. Normally, this means that the water is raised and lowered. Peter Fröhlich, though, decided to go […]
  4. Smell the rainbow with this olfactory device

    Do you ever wonder what certain colors would smell like? Perhaps red would emit the fragrance of a rose, while blue may be reminiscent of the ocean. During a recent workshop at ÉCAL in Lausanne, Switzerland, Niklas Roy challenged students to come up with new communication devices. In response, they devised an Arduino-based machine that senses a color and […]
  5. EduExo is a DIY exoskeleton kit

    You’ve seen exoskeletons in movies such as Aliens and Iron Man, and perhaps even heard about current experiments with human use. Unfortunately though, if you want to learn about this technology, the barrier to entry is very high. EduExo, now available on Kickstarter, is an attempt by robotics researcher Volker Bartenbach to bring this technology […]
