This project is a wifi synchronised desktop clock using 7-segment displays. The heart of the project is a ESP8266 board. The ESP8266 is a awesome chip; with integrated WiFi, 80MHz clock speed, total 160kb RAM, 512kb of flash memory, and a ton of other features, it makes a regular...

This project shows how to measure temperature data from a TSYS01 Temperature Sensor board using Arduino: While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple...

Michael Dunn@ edn.com discuss about current sense on the high side of power source. At their heart, the majority of DC current sense circuits start with a resistance in a supply line (though magnetic field sensing is a good alternative, especially in higher-current scenarios). One...

This is the second and final article of the Eagle Tips from allaboutcircuits.com: Before searching on the internet for new libraries to add to Eagle, first make sure that your device does not already exist in your local libraries. To check, use a search pattern that includes...

by Clemens Valens @ elektormagazine.com discuss about a new type of dissolvable memory resistor using egg proteins. Over the past years research has been done with several biodegradable materials, including DNA, to make what is called transient electronics, dissolvable electronic...

The Tiny Step-Down DC-DC converter project provides 5V 500mA output from supply input up to 25V DC. MC34063A IC is heart of the project from on semiconductor. The MC33063A is a monolithic control circuit containing the primary functions required for DC-DC converters, This device...

GreatScottLab @ instructables.com build a step up dc-dc converter with the help of ATtiny85 microcontroller. In this project I will show you an efficient and common way how to step up DC voltages. I will also demonstrate how easy it can be to build a boost converter with the help of...

This is a short tutorial on how to copy parts from one library of Eagle to the other. Copy parts between libraries in Eagle -...
