A friend of mine is a scientist who does experiments that are very sensitive to air temperature and humidity. The incubator room has a small ceramic heater but the heater’s thermostat was not nearly accurate enough, only able to maintain the temperature within 10-15 degrees. Commercial devices that log temperature and humidity can be quite […]

When it comes to building the battery packs, Li-ion cells are one of the best choices without the doubt. But if you get them from old laptop batteries then you might want to do a capacity test before building the battery pack. So today I will show you how to make a Li-ion capacity tester […]

If you are looking for a tiny three-color E Ink display, the Wemos D1 Mini board can fit the bill perfectly, more so given that it comes for just $10 a pop. Developed by Lolin, the display is all of 2.13-inch having support for red, black, and white colors. Further, the display has a resolution of 214 […]

Today I’m gonna make 3D Printed Unicorn Horn. I saw and did the project in Adafruit’s website about a year ago but I could not find an opportunity to share it. It looks great when going out to the party and especially in the evenings. 🙂 I got the horn out of the 3D printer […]

This was my project for Hack Sioux Falls. I built it one weekend and it turned out a lot different than I thought it would. It was a lot of fun and there are a lot of variations on what you could have the Arduino code do once you get the shadowbox wired up. My […]

Last month we brought you word of tonyhax, a clever exploit for the original Sony PlayStation that leveraged a buffer overflow in several of the games from the Tony Hawk Pro Skater series to load arbitrary code from a specially prepared memory card. But now [Bradlin] has taken that idea a step further and developed a software exploit […]

Multirotors, or drones as they’re popularly called, are so ubiquitous as to have become a $10 toy. They’re no less fun to fly for it though, and learning how they work is no less fascinating. It’s something [Science Buddies] has addressed in a series of videos examining them from first principles. They may be aimed at […]

In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel. Let’s get started! […]

I think this is a topic every parent is struggling with. How much can the kids play with their iPads (or any other tablet). We tried multiple approaches, like fixed times, but that did not really work as our kid then always wanted to go home the moment he was allowed to play with his iPad. […]

We will be the first to admit that it’s often hard to be productive while working from home, especially if no one’s ever really looking over your shoulder. Well, here is one creepy way to feel as though someone is keeping an eye on you, if that’s what gets you to straighten up and fly […]
