Google’s quantum computer just accurately simulated a molecule for the first time
https://www.electronics-lab.com/googles-quantum-computer-just-accurately-simulated-molecule-first-time/
Google’s engineers just achieved a milestone in quantum computing: they’ve produced the first completely scalable quantum simulation of a hydrogen molecule. by DAVID NIELD @ sciencealert.com Researchers working with the Google team were able to accurately simulate the energy of hydrogen H2 molecules, and if we can repeat the trick for other molecules, we could […]
Measure Weights Using OpenScale from Sparkfun
https://www.electronics-lab.com/measure-weights-using-openscale-sparkfun/
Sparkfun has a simple-to-use and open source solution for measuring weight and temperature. All you need is a load cell hooked up with OpenScale. You may find a variety of high quality weight sensors to be used in this project on Flintec load cells. OpenScale uses HX711, a 24-bit analog-to-digital converter (ADC) specifically designed for […]
Arduino Proximity Alarm
https://www.electronics-lab.com/arduino-proximity-alarm/
Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for nearby objects and if need be, alert you with […]
Neopixel Night Light using ATtiny85
https://www.electronics-lab.com/neopixel-night-light-using-attiny85/
joshua.brooks @ instructables.com describes how he build a night light using an Adafruit NeoPixel, ATtiny85 microcontroller, TSSP4038 IR receiver and some other easy available components. I’m giving some workshops in electronics in a few weeks, centered around an inexpensive, but useful real-world project. When trying to come up with a thing to make, I wanted it […]
A1367 – Field programmable linear Hall-effect sensor IC
https://www.electronics-lab.com/field-programmable-linear-hall-effect-sensor-ic/
Allegro MicroSystems Europe has added a field programmable precision linear Hall-effect current sensor IC with features including a 240 kHz bandwidth, integrated voltage regulator, reverse battery protection, user-selectable ratiometry, and uni- or bi-directional output options. By Graham Prophet The user can configure the sensitivity and quiescent (zero field) output voltage through programming on the VCC […]
Controlling Bus Pirate with Python
https://www.electronics-lab.com/controlling-bus-pirate-python/
Scott Harden show us how to control the Bus Pirate with python and give us example code. After using the AVR-ISP mkII for years (actually the cheap eBay knock-offs) to program ATMEL AVR microcontrollers, today I gave the Bus Pirate a shot. Far more than just a microcontroller programmer, this little board is basically a […]
Shenzhen: The Silicon Valley of Hardware (Full Documentary)
https://www.electronics-lab.com/shenzhen-silicon-valley-hardware-full-documentary/
Future Cities, a full-length documentary strand from WIRED Video, takes us inside the bustling Chinese city of Shenzhen We examine the unique manufacturing ecosystem that has emerged, gaining access to the world’s leading hardware-prototyping culture whilst challenging misconceptions from the west. The film looks at how the evolution of “Shanzhai” – or copycat manufacturing – […]
Embedded Systems Online Training Resources
https://www.electronics-lab.com/embedded-systems-online-training-resources/
Online learning of embedded system and electronics in general still bounded, and this is mainly related to the nature of hardware it self. Anyway, efforts for embedded systems training/learning continue to appear especially with MOOC platforms like Coursera and edX. In this blog post, i’m not going to talk about MOOC online courses. I’m going […]
Diode or MOSFET as a Reversed Voltage Protector
https://www.electronics-lab.com/diode-mosfet-reversed-voltage-protector/
Diode or P-channel MOSFET is what you need to protect your circuit from applying reversed voltage, according to a nice video published on Afrotechmods channel. Method 1:Diode The simplest way is to use a diode in series with main power supply. When you connect the power source right, the diode anode is connected to positive […]
What Will Happen to Moore’s Law in 2021?
https://www.electronics-lab.com/will-happen-moores-law-2021/
Moore’s law states that the number of transistors doubles every two years. Rachel Courtland from IEEE Spectrum explained the sharp turn of Moore’s law in 2021. Chip manufactures will switch to another way of boosting the density in the chip by having multilayer chips using vertical geometry, and we’ve already seen the 3D concept in […]
