When my children got these interesting and very obnoxious toy dinosaurs last year, I could barely contain my excitement. I knew that one day, they would be on my work bench giving up their secrets. Cruncher is a fairly recent addition to the robotic animal trend that we’ve been seeing the past few years. Imbued [...]

While being caught out in the rain skiing, [Andrew] was left with a pair of soaking wet gloves. Leaving them to air dry did little good, as after 3 days they were still wet, and blowing a fan at them did little to nothing to help the situation. Luckily [Andrew] had been thinking about ways [...]

Reader [Xellers] sent in his newest instructable: DIY Electron Accelerator: A Cathode Ray Tube in a Wine Bottle. While not exactly what you might think of a cathode ray tube, the basics are in place. A wine bottle is used as a vacuum chamber and a 9kv neon transformer is attached to a stopped in [...]

Imagine that you have been asked to construct a portable shipping container workshop that will be sent to the other side of the globe, where the power grid is sketchy and the resources tight. If you had $20,000 to outfit this 20’ container, what components and tools would you include? This was the question recently [...]

[Grenadier] Had some spare wire, electrical tape, and a giant ferrite core laying about and decided to create a massive and pretty snappy looking disk shaped flyback transformer. Dubbed the Fryback, he claims that it will “revitalise your health and bring wondrous wealth and prosperity to your family”. He chose a disk shaped transformer because [...]

[Jeri Ellsworth] had a bright idea – a brain-activated light bulb that floats above your head. While out and about, she saw some guy with a video game icon attached to metal rod sticking out of his backpack. The rod made the icon appear to be floating above his head (think The Sims), which was [...]

We have been featuring some home made capacitors this week, and [Mike] wrote in to share his with us. While rolled capacitors are nice, they can be somewhat difficult to construct and grow to unwieldy sizes as capacitance and voltages increase. His solution is to stack the layers up using plastic plates. In this forum [...]

[PT] just published an editorial calling on manufactures to transfer knowledge about products they are discontinuing by making them open source.

Something new is coming to a store near you: electronic price tags. [deadbird] decided to get one and see what makes it tick.

Although technology is constantly racing to faster / smaller / more, so many of the fundamentals of how it is made remains similar, if not the same.

This isn’t a hack. But it is a decidedly interesting piece of mechanical technology. The Whiffletree shown above is a way to turn binary data into a mechanical analog value.

If you’ve ever designed an embedded system with at least one button you’ve had to deal with button debouncing.

The Flash_Destroyer finally succeeded in rewriting that EEPROM until its demise. When we originally looked at the device it had already recorded 2.5 million successful rewrites.
