Lukas Fässler has designed a MPPT Solar Charger Arduino Shield and document it on the link below. A Solar MPPT charger is used to convert the solar panel voltage to the optimal voltage for charging a battery in the most efficient way. This way the solar panel works on the maximum...

David @ robotroom.com build a microcontroller based LED tester with LCD display that shows the LED voltage, the current limit in mA, the desired led voltage and the calculated resistor value. The LED tester is based on ATtiny84 mcu which performs all the measurements and calculations...

Rui Santos @ randomnerdtutorials.com has compiled a list of 25 useful Arduino Shields that you might want to use on your next projects. The list includes Ethernet shield, Relay, Motor, LCD and many more. Arduino shields are boards that will expand the functionalities of your...

Researchers at the Eindhoven University of Technology in the Netherlands have created what they call the tiniest temperature sensor that is powered by the same wireless network it uses to communicate data. The sensor measures 2 square millimeters and needs no physical connection to...

The Minibot is a small autonomous robot vehicle that uses phototransistor that can detect lightness patterns on the ground to follow the edges of the dark lines. It has a MC9RS08KB4 MCU, coin cell, motor, and a phototransistor. The MC9RS08KB4 is part of the MC9RS08KB12 series, a...

Rui Santos @ andomnerdtutorials.com has tipped us with his latest project. In this project Rui connects two ESP8266 modules and sends data from 3 sensors to an Excel spreadsheet. The process is explained in detail and some prior experience with ESP8266 is necessary and provided in...

makers @ hackerspace.pl decided to hack the Zsun Wifi SD Card Reader and run OpenWrt on it and turn it on a awesome wifi device. Hacking the Zsun WiFi SD Card Reader -...

MindForge @ 43oh.com build a datalogger board which logs accelerometer values on a SD Card. The datalogger is built around an MSP430G2755 microcontroller and ADXL335 accelerometer sensor from Analog Devices. his project started as an EMG datalogger to study my dad’s Parkinson’s...
