Volumetric displays are simply cool. Throw some LEDs together, take advantage of persistence of vision, and you’ve really got something. [Nick Electronics] shows us how its done with his neat little volumetric lamp build. The concept is simple. [Nick] built a little device to spin a little rectangular array of LEDs. A small motor in […]
Face it, we’ve all at some time or other looked at our hot glue guns, and thought “I wonder if I could use that for 3D printing!”. [Proper Printing] didn’t just think it, he’s made a working hot glue 3D printer. As you’d expect, it’s the extruder which forms the hack here. A Dremel hot […]
Out of curiosity, I redrew the Supercon Vectorscope badge schematics in KiCad last year. As you might suspect, going from PCB to schematic is opposite to the normal design flow of KiCad and most other PCB design tools. As a result, the schematics and PCB of the Vectorscope project were not really linked. I decided […]
If you’ve ever wondered what goes on in the ground facilities of a satellite TV operation, you could go banging on the doors or your local station. You’d probably get thrown out in short order. Alternatively, you could watch this neat little tour from [saveitforparts]. The tour takes us through a ground facility operated by […]
We hate to admit it, but whenever we see an article about either Voyager spacecraft, our thoughts immediately turn to worst-case scenarios. One of these days, we’ll be forced to write obituaries for the plucky interstellar travelers, but today is not that day, even with news of yet another issue aboard Voyager 1 that threatens […]
Although we think of air-to-air radar as a relatively modern invention, it first made its appearance in WWII. Some late war fighters featured the AN/APS-13 Tail Warning Radar to alert the pilot when an enemy fighter was on his tail. In [WWII US Bombers]’ fascinating video we get a deep dive into this fascinating piece […]
For a first try at an electric vehicle conversion we’re guessing that most would pick a small city car as a base vehicle, or perhaps a Kei van. Not [LiamTronix], who instead chose to do it with an old Ferguson tractor. It might not be the most promising of EV platforms, but as you can […]
From the 60s to perhaps the mid-00s, the path to musical stardom was essentially straight with very few forks. As a teenager you’d round up a drummer and a few guitar players and start jamming out of a garage, hoping to build to bigger and bigger venues. Few people made it for plenty of reasons, […]
All your Nintendo Alarmo are belong to mew~ (Credit: GaryOderNichts, Blogspot) Most of us will probably have seen Nintendo’s latest gadget pop up recently. Rather than a Switch 2 announcement, we got greeted with a Nintendo-branded alarm clock. Featuring a 2.8″ color LCD and a range of sensors, it can detect and respond to a […]
