Science fairs are no longer the sacred domain of potato clocks and erupting volcanos. Sohila Sidhu and the five other winners at the recent Windsor Regional Science, Technology and Engineering Fair (WRSTEF) have taken their projects light years beyond the reaction between baking soda and vinegar. Sidhu, a 15-year-old Assumption College High School student, won […]

Like many of you, we’re intrigued by the possibilities offered by the availability of affordable round LCD panels. But beyond the smartwatches they were designed for, it’s not always easy to come up with an appropriate application for such non-traditional displays. Digital “steam gauges” are one of the first ideas that come to mind, so

In the Northern hemisphere, summer is about to hit us full bore. While we love the season, we do dislike lawn maintenance. Apparently, so does [salmec] who developed the Mowerino around an Arduino Mega 2560 board. As you might expect, the robot uses sharp blades so, you probably want to be careful. There are sensors that allow
SUMMER’S COMING – LET MOWERINO CUT YOUR GRASS Continue Reading
Trust me, you don’t have to build your own keyboard from the deskpad up to be happy or feel like one of the cool kids. Sure, it doesn’t hurt, but not everyone is able to or even wants to start from next to nothing. Take [Roger] for example. [Roger] started with a stock mechanical keeb

Mylar has a lot of useful properties, and as such as see it pop up pretty often, not just in DIY projects but in our day-to-day lives. But until today, we’ve never seen a piece of Mylar jump up and try to get our attention. But that’s precisely the promise offered by ElectriPop, a fascinating project

[Jure Spiler] was at a flea market and got himself a spectrophotometer — a device that measures absorbance and transmittance of light at different wavelengths. This particular model seems to be about 25 years old, and it’s controlled by a built-in keyboard and uses a graphical LCD to display collected data. That might have been acceptable when

Baseball jokes aside, holograms have been a dream for decades, and with devices finally around that support something like them, we have finally started to wonder how to make content for them. [Mike Rigsby] recently entered his stop-motion holographic setup into our sci-fi contest, and we love the idea. Rather than a three-dimensional model or a 2d picture

You can’t do much development without running into Git, the version control management system. Part of that is because so much code lives on GitHub which uses Git, although you don’t need to know anything about that if all you want to do is download code. [Dr. Torq] has a good primer on using Git with

Electric vehicles (EVs) are something of a hot topic, and most of the hacks we’ve featured regarding them center on conversions from Internal Combustion to Electric. These are all fine, and we hope to see plenty more of them in the future. There’s another aspect that doesn’t get covered as often: How to charge electric vehicles- especially

Hooking up a laser to a CNC gantry isn’t exactly an Earth-shattering innovation, but it does make for a useful tool. Even a cheap diode laser mounted to an old 3D printer can do engraving, marking, or even light-duty cutting. But what about a laser engraver without the laser? Can that be of any use?
NO-LASER CNC ENGRAVER IS SOMETHING NEW UNDER THE SUN Continue Reading
