Tisham Dhar designed an ATM90E26 energy meter breakout board which can be used in single phase power measurements. After designing and testing the ADE7763 based Energy Monitor Breakout Board, I started looking around for cheaper and more modern alternatives.I came across the Atmel...

Paulo has developed an Excel-based calculator that eases the design of RC snubbers in power switching applications: In power switching applications, a designer often has to contend with spurious oscillations. These are the result of parasitic capacitances and inductance on the board...

For the first time, scientists at IBM Research have demonstrated reliably storing 3 bits of data per cell using a relatively new memory technology known as phase-change memory (PCM). The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But...

This tutorial will show how to interface a 8x8 LED matrix with Arduino. Example code is provided. LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a...

Bipolar stepper drive board described here has been designed around TB6600HG IC. The TB6600HG is PWM chopper type single chip bipolar sinusoidal micro-step stepping driver. Maximum  Load 4.5A, Supply 10V to 42V DC. Features Based on Single chip and Second chip for auto half...

Oskar Weigl @ hackaday.io designed a brushless motor controller able to drive 2 motors. Hobby brushless motors are incredibly cheap and powerful. However we need a way to make robots out of them. ODrive is that way. Stepper motors are ubiquitous in hobby robotics projects: If you...

Raj over at Embedded Lab has designed a development board for PIC16F1938: The PIC16F1938 is a versatile 28-pin MCU belonging to Microchip’s extreme low power microcontroller family featuring nanoWatt XLP technology, 28KB of programming memory, 1KB of RAM, 11 ADC channels, and...
