150V DC/DC inverting controller: single inductor, ground-referenced control


https://www.electronics-lab.com/150v-dcdc-inverting-controller-single-inductor-ground-referenced-control/

LTC3896 is a high voltage inverting switching regulator controller that drives an all N-channel synchronous power MOSFET stage. Most low to medium power inverting DC/DC converters use a coupled inductor or transformer: this device uses only a single inductor. The chip converts a 4V to (150V – |VOUT‾|) positive input voltage to a regulated negative […]

Curve Tracer Project


https://www.electronics-lab.com/curve-tracer-project/

Jason Jones has tipped us with his latest project. He is working on a semiconductor curve tracer and details his progress on his website. I have thought about this a lot recently and – in order to get the cost down – the unit must have a cheap or available power supply and must coopt […]

This is a tutorial on how to use a 433MHz long range transmitter/receiver with Arduino. I just explain how i have use the 433MHz RF Long Distance Transmitter / Receiver Pair and a arduino to install it on my rc truck for a firework ignition, lamp , pan tilt camera system How to Use Arduino […]

DIY Mini Quadcopter with 3D-Printed Frame and Custom Firmware


https://www.electronics-lab.com/diy-mini-quadcopter-3d-printed-frame-custom-firmware/

Simon D. Levy designed and build a mini quadcopter with 3D printed frame and custom C++ firmware. See the full project notes including bill of materials and more photos on the link below, and check out Simon’s blog on the C++ firmware here. I wanted to try my hand at a true “DIY” project, designing […]

Energy monitoring using ATM90E26


https://www.electronics-lab.com/energy-monitoring-using-atm90e26/

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 ATM90E26 Smart Metering IC with dual communication options – UART/SPI and multiple […]

RC snubber calculator spreadsheet


https://www.electronics-lab.com/rc-snubber-calculator-spreadsheet/

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 and behave like the step response of an RLC circuit. These transients can […]

IBM scientists achieve storage memory breakthrough


https://www.electronics-lab.com/ibm-scientists-achieve-storage-memory-breakthrough/

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 in the last several years PCM has attracted the industry’s […]

Interfacing 8×8 LED Matrix with Arduino


https://www.electronics-lab.com/interfacing-8x8-led-matrix-arduino/

This tutorial will show how to interface a 8×8 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 single color 8×8 LED matrix with […]
