A hands-on test of a small lamp powered by the heat of a candle through thermoelectric generator (TEG) modules, measuring real performance, efficiency limits, and practical off-grid applications.
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…
Let’s interface our Energy Meter with Internet to bring measurements to the ThingSpeak platform and see the results in convenient graphs. A few posts ago, we introduced the MCP39F511 integrated circuit, capable of performing electrical measurements in single-phase electrical systems through the FT1346M board. We have integrated it with the GSM board and…
It monitors the electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and a board on which the measurement board is mounted. Second and final instalment. In the previous post on Open Electronics, we have proposed…
It monitors electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and an absorption detector board. First instalment. Monitoring the electricity consumption of your home or business is an increasingly topical issue. The electrical measurements made,…
A Solar tracker was created in order to focus solar panels perpendicular to incoming sunlight. This position of the solar panel is optimal for photovoltaic energy generation. The efficiency of the Solar Tracking system vs normal use of solar panels was compared using data collected by my Arduino Power Logger (See details of Power…
This uses a buck converter as a 5V Output to charge the battery(Li Po/Li-ion). And Boost converter for 3.7V battery to 5V USB output for devices needed 5 V. Similar to the Original system that uses Lead Acid Battery as an energy storage charge by either PWM or MPPT controller. And supply for 12V Devices. This One only uses…
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…
The Autonomous Rover travels from one location in my house to another location in my house, with no help from a human. I designed it to experiment in robot autonomy. To perform its task, the AR (short for Autonomous Rover) integrates three major capabilities: Localization — determines its current location in its environment Navigation — determines the…
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…
In this project we see how to build a dual axis solar tracker with photovoltaics. The photovoltaic itself will power the tracking system, so no external power source is needed. To track the sun, we used four LDR sensors, Arduino UNO compares the data provided by them to rotate the panel in the direction with…
