MIT recently announced its research on toroidal propellers to create quieter drones. That got [Major Hardware] thinking about noisy PC fans. The obvious solution was to adapt the toroidal shape …read more Continue reading Spy Drone Propeller Makes for a Quiet PC
In the old days, scanners would listen to a bunch of channels in a round-robin fashion. If a signal breaks the squelch, the scanner stops and scanning continues scanning after …read more Continue reading SDR Scanner Listens to Everything
If you are running video around your home theater, you probably use HDMI. If you are running it in a professional studio, however, you are probably using SDI, Serial Digital …read more Continue reading Arduino Does SDI Video with FPGA Help
We always enjoy unique clocks, and a recent 3D print from [David Kingsman] caught our eye. It converts an Ikea clock into a very unusual-looking “wandering hour” clock that uses …read more Continue reading Ikea Clock Gets Wanderlust
In the early days of C, you’d occasionally see someone — probably a former Pascal programmer — write something like this: #define BEGIN { #define END } This would usually …read more Continue reading Hacking the Python For Loop
We see a lot of clocks, and many of the better ones have some 3D printed elements to them. But [Carl Sabanski] shows us his kits for making sundials for …read more Continue reading Sundial Collection is 2D Printed
One of the fun things about “old school” computers is that it was fairly easy to get kids into programming them. The old Basic interpreters were pretty forgiving, and you …read more Continue reading Scratch Your Itch to Program a Microcontroller
Some of you probably know this already, but there’s actually more than one kind of electron microscope. In electronics work, the scanning electron microscope (SEM) is the most common. You …read more Continue reading Electron Microscope Conversion Hack
What do you do if you want a tiny little adjustable wrench? If you’re [my mechanics] you build your own. Where do you get the stock metal? Well, he started …read more Continue reading DIY Adjustable Wrench? Nuts!
Spectrometry is a well-known technique or, more correctly, a set of techniques. We usually think of it as the analysis of light to determine what chemicals are producing it. For …read more Continue reading RF Spectrometer Sees Inside
