How-To: Switchable-Polarity 250,000 Volt Power Supply
In today’s project on diyphysics.com, David Prutchi shows how to build a Cockcroft–Walton multiplier using a “ladder” of capacitors and diodes on perfboard, submerged in mineral oil, inside a sealed plastic container. The multiplier takes high voltage AC, e.g. from a TV flyback transformer, and both rectifies it to DC and steps it up considerably. […]
How-To: Vintage Train Case Charging Station
One of my good friends has a beautiful and fun collection of vintage train cases that she displays in the bookshelves in her living room. Their colors and cool vintage design makes them the perfect eye candy, and their roomy interiors make them practical for storing things like DVDs and video games. Here’s one more […]
NTH Hackable Synthesizer
Columbus, OH makers Kevin Holland and John Staskevich have built a seemingly fun to play hackable synth using a PIC microcontroller, 8-bit DAC, and analog low-pass filter. It includes an integrated step sequencer and simple, intuitive controls. The device was built with hacking in mind, so you’ll also get a spare hardware DAC channel, on-board […]
“How Maker Faire Changed My Life”
Ben Hylak, one of the young scientists/inventors honored at the White House yesterday, wrote his touching and inspiring story for the CNN website. The story, and an accompany teaser video, are a preview to this weekend’s episode of “The Next List” on CNN.
How-To: Compressed Air Foam Systems
MAKE regular Mike Pantrey, aka Mrsuperpants, returns with this cool page about building on-the-cheap DIY versions of the commercial systems used to make foam and/or “snow” for video, photo, and event special effects. He describes three iterations of his homemade CAFS and a method for making colored foam. [Thanks, Mike!]
