Two years ago, the Sculpto 3D printer appeared to make 3D printing more affordable and user-friendly for everyone. Recently, the new version Sculpto+ came with more useful features, making it a unique printer with the same printing area and price range. The Sculpto+ printer is a compact printer for beginners, kids and adults to start […]

The common magnetic loudspeaker is, fundamentally, a fairly simple machine. A static magnetic field is generated by a permanent magnet, and a membrane is mechanically connected to a coil. When a varying electrical current is passed through the coil, this causes the coil to move due to the magnetic field, vibrating the membrane and producing

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots

When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to understand each other? Communication between electronic devices is like communication between humans. Both sides need to speak the same language. In electronics, these languages are

The YouTube channel DIY Builder has published and created a DIY Arduino laser engraver which is powered by an Arduino Nano development board and is fitted with a 200-250mW 650nm Laser Module. Check out the video below to learn more about the DIY Arduino laser engraver constructed using the innards from an old PC DVD player. A

Normally -according to the Ohm’s law– when the applied voltage is increasing, the current is increasing too, however some components can break this law. When the voltage increases, current decreases. This is called negative resistance. One of the most know element that exhibits this behavior is a tunnel diode. Once very promising, today it isn’t
Simple negative resistance oscillators Continue Reading
Everyone believes the future is going to be bright and a lot are betting that smart devices of the future will have the ability to self-adapt to its environment and that’s why some are backing on Cognitive Radios which are Software Defined Radios with AI. Our world is becoming crowded with several smart devices, and the explosion of

Maxim Integrated has developed an algorithm to accurately estimate the battery state of charge and safely handle most batteries. Designers of lithium-ion (Li-ion) battery-powered devices such as wearables, electric bicycles, power tools and internet of things (IoT) products can improve the end-user experience by extending run-time and delivering accurate battery state-of-charge (SOC) data with the

First of all, Happy New Year 2017! I hope all of yours starts the new year with good intentions. The mine one is write frequently here. Family and work don’t let me much free time but I’ll try it! For several months I’m working with FONA808 modules from Adafruit to make a portable, web-based locating
