2.7V-4.2V input to 3.3V output Buck-Boost Converter
https://www.electronics-lab.com/2-7v-4-2v-input-3-3v-output-buck-boost-converter/
This project shows a DC-DC buck boost circuit which can produce an output of 3.3V for an input of 2.7V to 4.2V , for example from a Li-on battery. The Circuit uses LTC3440 Buck boost IC which is a fixed frequency boost converter. To get high efficient results, inductor with high frequency core material should […]

Human Motion Powered Nanotechnology Devices
https://www.electronics-lab.com/human-motion-powered-nanotechnology-devices/
Michigan State University researchers have came up with a new method for harvesting energy from human motion using nanotechnology. They designed a low-cost film-like device, a nanogenerator, than can power a LCD display, keyboard, and some LEDs without any source of electric power, by only using some human touching or pressing. This device called FENG, […]

Emulate an Apple ][ on an AVR Microcontroller
https://www.electronics-lab.com/emulate-apple-avr-microcontroller/
The Apple II personal computer, which stylized as Apple ][, is an 8-bit home computer and one of the first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak and developed with Steve Jobs. Apple ][ was introduced in 1977 at the West Coast Computer Faire by Jobs and was sold several […]
Software Defined Radio IC Decap
https://www.electronics-lab.com/software-defined-radio-ic-decap/
Software Defined Radio teardown: R820/RTL2832U Decap Recently there has been much interest in two integrated circuit which were originally designed to receive FM radio and DVB-T TV (as used in Europe). Some enterprising people quickly realised that since they were based on software-defined techniques they could be quickly re purposed for all sorts of clever […]
How to Set Up and Program an LCD Display on an Arduino
https://www.electronics-lab.com/set-program-lcd-display-arduino/
circuitbasics.com writes: In this tutorial, I’ll explain how to set up an LCD display on an Arduino, and show you all the functions available to program it (with examples). The display I’m using here is a 16×2 LCD display that I bought for under $10 on Amazon. LCDs are really useful in projects that output data, and they can make your project […]
