There are plenty of other things you can do too, but as highlighted in the journal Environmental Research Letters, the best courses of action are often rarely reported about. This may →

https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-acorn-computers-arm1-processor Unsatified with the processors then available on the market, the Acorn engineers decided to make the leap to creating their own 32-bit microprocessor. ARM1 was released in 1985. They called it the Acorn RISC Machine, or ARM. In 1990, Acorn spun off its ARM division, and the ARM architecture went on to become the dominant →

This script was created by author of www.p01.org where you can find this and many other cool demos. The article writer found it was fun trying to understand the code. →

https://www.hackster.io/chauhannaman98/reducing-arduino-power-consumption-f8d49d?ref=explore&ref_id=trending___&offset=0 The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry for small battery powered devices (15 mA for UNO). It is possible to drastically bring power consumption down with just a few tricks. In this guide we’ll see if we can reduce the supply →

I bought some years go SILVERCREST Li-lon Rechargeable Handheld Vacuum Cleaner. After those years it does not work properly anymore: it runs just few seconds even though fully charged and then did not start at all. I thought that maybe batteries were going bad. Time for tear-down: Gg Opening the device… Here is the elecronics. →

https://opensource.com/article/17/7/nodered-raspberrypi-hardware?sc_cid=7016000000127ECAAY Node-RED is an easy-to-use programming tool that can be used for handling IoT signals. This article shows that Node-RED can also be used to quickly integrate and test hardware devices. As you can see from this tutorial, connecting and testing a cellular mode with Raspberry Pi using Node-RED required no coding at all. For more information about →

http://www.instructables.com/id/Voice-Controlled-Bluetooth-Car/ This looks really interesting! Everyone has used the remote controlled car…. but what about a voice controlled car??? Ever used it?If not then you will build it now. Just you need an arduino as the brains and a smartphone.  Arduino nano is the brains of the project. Now the voice feature actually works with →
