Being Engineers @ instructables.com writes: Hello guyz, Welcome to Being Engineers. Hope you all are doing good. In this tutorial we will learn how to make your own Arduino Uno. We will gather the components, test the circuit in breadboard, then we will make the board itself. When it...

GreatScottLab @ instructables.com writes: In this project I will show you how to create an Arduino based soldering station for a standard JBC soldering iron. During the build I will talk about thermocouples, AC power control and zero point detection. Let's get started! DIY Arduino...

by Pesky Products @ tindie.com: This is a small (0.5 x 0.5 inch) breakout board for Texas Instrument's BQ25504 Ultra Low Power Boost Converter with Battery Management for Energy Harvesting Applications. BQ25504 Solar Cell LiPo Charger -...

by Eric Bogers @ elektormagazine.com: Nanotechnology repeatedly breaks new records in the area of miniaturization. However, there are physical limits when reducing the size of electronic components and these will be reached in the near future. This means that new materials and...

The pressure sensor amplifier built using LM358 op-amp and MPXM2051GS pressure sensor from NXP semiconductor.  The circuit provides 4V output for full scale pressure input 0-7.5PSI.  One op-amp is used as amplifier and 2nd op-amp is used as comparator to provide an output at set...

The serial controlled 50 Segment Bar-Graph Display built using CAT4016 IC. Very useful projects for development Bar-Graph based, Temperature Meter, Interactive Games, Voltage Display, Current Display., Pressure Sensor, Magnetic field meter and PH Meter. Tilt meter, LUX meter. The...

The circuit presented here is based on LTC3601, a high efficiency, monolithic synchronous buck regulator from Linear Technology. The circuit operates at an input voltage ranging from 4V to 15V, this makes it suitable for a wide range of power supply applications. It is capable of...

Alex the Giant @ sparkfun.com has a tutorial on how to build smart and connected water sensor using ESP32. He writes: For this project, you can use either the ESP8266 Thing, or the ESP32 Thing. One of the many improvements made on the ESP32 is the capacitive touch circuitry built in...
