There was a time not that long ago when every tool was cordless. But now, cordless power tools have proliferated to the point where the mere thought of using a plain old wrist-twisting screwdriver is enough to trigger a bout of sympathetic repetitive injury. And the only thing worse than that is to discover that […]

Hello everyone, and welcome to my Instructable! This instructable will show you how I made the first ever DIY Arduino controlled “LED Kaleidoscope”! What is an LED kaleidoscope? Well, our traditional kaleidoscopes used 3 mirrors joined as a triangle with stuff like sequins and stolen cake decorations at one end, to create an awesome pattern

Although the WSEN-TIDS temperature sensor from Würth Elektronik measures just 2.0 x 2.0 x 0.5 mm, its range of application is wide: Its accuracy in the measuring range -40 to 125°C is ±0.5°C, while in the range -10 to 60°C it goes down to ±0.25°C. Applications extend from PCB temperature monitoring and system monitoring for power supplies, heating, ventilation,

I always wanted to make a PCB and this is my first professional circuit board attempt. So before you decide to start this project you should know there could be some mistakes or it could be more reliable and compact. This design is not the most efficient and cheapest way to make a DIY MPPT

As the world continues in the fight against Covid19, makers, developers, Engineers, and open source communities are joining in the fight by creating solutions ranging from open source ventilators to treat people who are sick, to 3D printed face masks to prevent the sickness. One of such solutions, which falls into the latter category, is the ‘Social

“Marblevator, Pertual?, Cradle” like “Marblevator, Perpetual?, Version 2” and “Marblevator, Perpetual?” is not perpetual at all as it is simply another illusion. And like its predecessors it is a very quiet illusion with the only noise being that of the marble as it rolls back and forth in the cradle. I’ve incorporated an Arduino Nano

There are so many authentic looking lightsaber build guides but not many on building a super long lightsaber. Regarding Star Wars, I’m not sure why lightsabers are normal sword size anyway. Its not like the longer the lightsaber, the harder it would be to swing. I assume they are essentially weightless. Just make it 10′

While keeping batteries small and light is definitely a factor with electronic devices in general, it becomes particularly important when dealing with wearable electronics such as smart glasses. With that in mind, Panasonic has just announced its CG-320. Measuring 20 x 3.5 mm, it’s being billed as “the industry’s smallest cylindrical shaped rechargeable Lithium Ion

ONiO, a Norwegian healthcare-focused Internet of Things (IoT) expert has unveiled ONiO.zero, an ultra-low-power RISC-V-based microcontroller capable of operating solely from harvested energy — without needing a battery, capacitor, or any other means of energy storage. The company says “ONiO.zero is an ultra-low-power wireless MCU that uses energy harvesting technology.” This indicates that the ONiO.zero solely functions on energy harnessed from its surroundings. With
