Competitive Programmer’s Handbook

“The purpose of this book is to give you a thorough introduction to competitive programming. It is assumed that you already know the basics of programming, but no previous background in competitive programming is needed. The book is especially intended …

Core Rope Memory

“The 50th anniversary of the Apollo mission brought around lots of projects and talks about the technology that made the mission possible. One item that always fascinated me is “magnetic core memory”, a type of RAM made of tiny ferrite …

Developing embedded systems faster

“Whether for the car or the drone: Developing image processing software for embedded systems takes a lot of time and is therefore very expensive. Now the Tulipp platform makes it possible to develop energy-efficient embedded image processing systems more quickly …

DIY Function/Waveform Generator

“In this project we will have a short look at commercial function/waveform generators in order to determine what features are important for a DIY version. Afterwards I will then show you how to create a simple function generator, the …

Project  DrumKid

DrumKid

“Concept A drum machine which generates rhythms using probability. Imagine a traditional step-based drum machine, but where various dice are rolled for each step, with the resulting numbers used to determine the behaviour of the beat. Setup DrumKid is based …

Engineers develop multimaterial fiber “ink” for 3-D-printed devices

“Filaments with embedded circuitry can be used to print complex shapes for biomedical and robotic devices. A new method developed by MIT researchers uses standard 3-D printers to produce functioning devices with the electronics already embedded inside. The devices are …

Project  Faster ESP32

Faster ESP32

“There are two ways to make the ESP32 GPIO stay at 0 or 1. You can call the #digitalwrite function, or you can go straight to the recorder. Im showing the second option today: how to go straight to the …

Flexible solar cells a step closer to reality

“· Discovery by University of Warwick scientists challenges accepted rule of organic solar cell design · Could help to bring about low cost, flexible and stable organic solar cells for use on vehicles, curved surfaces and windows · Reducing surface area of electrodes …

‘Flying fish’ robot can propel itself out of water and glide through the air

“A bio-inspired bot uses water from the environment to create a gas and launch itself from the water’s surface. The robot, which can travel 26 metres through the air after take-off, could be used to collect water samples in …

Future of LEDs Gets Boost from Verification of Localization States Within Indium Gallium Nitride Quantum Wells

“Light-emitting diodes made of indium gallium nitride provide better luminescence efficiency than many of the other materials used to create blue and green LEDs. But a big challenge of working with InGaN is the material is known for dislocation density …
