There are numerous ESP8266 modules available, and they are often used in battery-powered IoT applications that, with the correct configuration, can run for months. In this guide, you will learn how to power an ESP8266 using lithium-ion batteries and how to configure it correctly. You will also be able to simulate battery life…
Voltaplex Energy launched Voltx.ai Alpha, a battery design automation cloud software that will enable engineering teams to rapidly prototype new lithium-ion battery pack designs. Voltaplex Energy believes Voltx.ai will become a world standard battery design tool because it is faster than human engineers by orders of magnitude at creating and comparing battery pack designs allowing…
I’ve been wanting to build this walker robot even since I saw it on YouTube. After a little searching I found some more information on it and decided to make my own. The goal I had building this walker was to try and make it as small as I possibly could. I wanted it…
We introduced this concept last year, and have launched three games so far. Our final game of 2019 was SumoBots Battle Royale — where players from anywhere in the world can fight real robots in a battle royale-style arena. The aim of the project was to have the game run semi-autonomously, meaning that the…
Researchers in Thailand have developed a ZigBee-based wireless monitoring solution for off-grid PV installations capable of tracking the sun across the sky, tilting the panel hourly. The elevation for the setup is adjusted manually once per month for optimum energy collection. The prototype is controlled by a local Arduino Uno board, along an H-bridge motor driver to…
Have you tried to test a battery capacity? How much was it difficult? Now a new DIY instrument allows you to identify a fake Lithium-Ion/Lithium-Polymer/NiCd/NiMH battery. You can also see on the LCD user interface to check the capacity of almost any kind of battery whose voltage il less than 5V. More info
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The growing demand for portable devices capable of working where there is no power grid or it is not convenient to use it is…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
The latest robot from Waveshare, it adds interesting features to the qualities of its predecessor. You were able to appreciate the instructional robotics platform on wheels called Alphabot, in an article dedicated to it, and you were able to see it in its version with Arduino controller. Alphabot, we remind you, is a robot…
A robotics development platform based on a two-wheel mechanics plus pivoting wheel on which you can prototype applications, controllable with popular Arduino Uno, Raspberry Pi 3 boards or both. Robotics is one of the most engaging parts of electronics because it can combine different fields of knowledge and skills in the same project; in…
