ATtiny85 Boost Converter

FAAOBO2IO6DZTEB.MEDIUM

GreatScottLab @ instructables.com build a step up dc-dc converter with the help of ATtiny85 microcontroller.

In this project I will show you an efficient and common way how to step up DC voltages. I will also demonstrate how easy it can be to build a boost converter with the help of an ATtiny85. Let’s get started!

WeMOS D1 ESP8266 vs Arduino Uno, Arduino Due and Teensy 3.2. Which one is the fastest board?

educ8s.tv uploaded a new video comparing the performance of ESP8266 Arduino board with the most popular Arduino boards.

In this video we are going to compare the computational speed of the WeMOS D1 ESP8266 based Arduino compatible board with the computational speed of the most popular Arduino boards and the Teensy 3.2. Let’s get started!

A few weeks ago, in a similar video we compared the performance of the Teensy with the most popular Arduino boards. Today, we are going to add another board to the comparison, the WeMOS D1 ESP8266 Arduino compatible board. I have prepared a detailed tutorial on that board so you can check it out before we start.

In order to compare the processing power of the boards, all the boards, the Arduino Uno, the Arduino Due, a Teensy 3.2 and the WeMOS D1 will run the same sketch. The Newton’s approximation of PI for half a million iterations. The time needed to execute this task is then displayed on a 1.8” Color TFT display. This way we are going to have a visual representation of the speed differences of the boards. In order to see how to connect the display with the Teensy or the Arduino boards check out the tutorial I have prepared on that. You can find links for all the parts in the description of the video.

Prototype to production: Arduino for the professional

ArduinoR3PinOuts

Jacob Beningo @ edn.com discuss how you can benefit from the Arduino platform if you are a professional.

Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed the Arduino as so simple it was nearly useless for professional developers. But I have changed my mind

Battery-charging considerations for low-power applications [PDF]

battery_charging

By Tahar Allag:

The wearable and personal-electronics industries are booming. Devices in this market vary wildly by application and use. These multifunction devices are designed to help people in their daily activities and make their lives comfortable. They can be found in different shapes, colors, sizes, and safety measures. They may differ significantly from each other, but they all have one thing in common—the need for a battery and a battery charger. These portable devices are typically powered by batteries installed internal to the device, which must be charged efficiently and quickly on a regular basis. The user’s charging experience also needs to meet the requirement of safety, comfort, and convenience.

Eagle CAD Tips and Tricks

cmdEagle

Most hobbyists and many professionals use Eagle CAD as a daily tool in designing schematics and laying out PCB. Yahya Tawil is going to share with us the most important tips and tricks for using Eagle CAD, which make your work much easier and faster.

My advice is to keep one hand on the mouse to do wiring, etc. inside the editor workspace and use the other hand on the keyboard to write commands and select tools. My advice of using the keyboard is not only for selecting tools. You will see the other benefits of using the keyboard in Eagle CAD in the rest of this series.

Mover Kit – The first active wearable that kids make & code

Mover_stills_42

Mover Kit encourages movement! It’s a game, speed-activated bike light, disco bracelet – whatever a kid can make, move & code it to be.

The Mover Kit is an intuitive way for kids ages 8 and over to learn the fundamentals of electronics, programming and solve problems creatively. It encourages kids to learn by doing what they do best – being active and playing! The Mover Kit was named Forbes’ Toy to Watch in 2016 and is loved by 300 kids that have tested it out so far.
