Perfect conditions for precision nanostructures

“Protein-folded DNA nanostructures offer a new building material for biotechnology. By using proteins that naturally bind and arrange DNA inside cells, a KAUST-led team has devised a plug-and-play strategy for building stable, custom-designed nanostructures. The versatile yet straightforward method …

Reducing open-circuit voltage loss in organic solar cells

“Researchers at Institute for Molecular Science in Japan report that organic solar cells (OSCs) with high mobility and highly crystalline donor (D) and acceptor (A) materials were able to reduce an open-circuit voltage (VOC) loss. The origin of the high …

Bow Tie PCB Badge

“Every party is different, and everyone wants to be unique, what do you think about wearing a printed circuit board bow tie? PCB badges have always been an artistic form of circuit board.I this project I will be showing …

Linear Variable Voltage Regulator 1-20 V

“A linear voltage regulator maintains a constant voltage at output if the input voltage is greater than output while dissipating the difference in the voltage times the current watts of power as heat. You can even make a crude voltage …

Mini Speaker Attached Audio Amplifier using TS4871

“This Mini Audio Power Amplifier is capable of delivering 1W of continuous RMS Output Power into 8 ohms load @ 5V. The Amplifier is built using TS4871 IC from ST. This Audio Amplifier is exhibiting 0.1% distortion level (THD) from …

Programming At89S52 Using Arduino

“In-System Programming (ISP) aka In-Circuit Serial Programming (ICSP) is the ability of some programmable logic devices, microcontrollers, and other embedded devices to be programmed while installed in a complete system, rather than requiring the chip to be programmed prior to …

TicTacToe Hardware Implementation Using RaspberryPi

“This project aims at building an interactive TicTacToe model using two different colored LEDs denoting the two players using a raspberry pi. The idea here was to implement this on a bigger scale in an alleyway - imagine a grid of …

USB PD Stand-alone Sink Controller

“Since USB-C’s introduction, I’ve been consistently interested in leveraging it for powering everything under 100 watt (or rather under 90 watt, since it’s hard to come by a full 100 watt USB-C power brick). I …

A CircuitPython BLE Remote Control On/Off Switch

“Make a remote control on/off switch for a computer with CircuitPython and BLE I have multiple computers around the house, and sometimes they need to be rebooted remotely. For example, here’s a surveillance camera server that’s located …

First Demonstration of a 1 Petabit per Second Network Node

“Gathering the latest advancements in optical fiber telecommunications technology towards practical petabit-class backbone networks The Network System Research Institute at the National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.) has developed and demonstrated the first …
