IDT Announces High Performance MEMS Relative Humidity & Temperature Sensor

California based company, Integrated Device Technology (IDT) has recently announced their new HS300x family of MEMS high-performance relative humidity (RH) and temperature sensors of dimension 3.0 × 2.41 × 0.8 mm DFN-style 6-pin LGA. Currently, there are four devices in this family—the HS3001, HS3002, HS3003, and HS3004. They are all the same from the view of functionality but differ slightly in terms of th ...

ArduinoPhone

Note that ArduinoPhone V2.0 had been published at Jan 26, 2016, click to view more details. Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it’s not such fine as you think, even a little bit clunky, it’s still very cool. That is the point this is a cell phone made by ourselves. While, we can’t install ...

Interfacing Arduino with Micro SD card Module

Introduction Often times, we have the need for a way to store data in our projects, and most of the time, the EEPROM which comes readily to mind has a limited storage capacity, and issues with the format and nature of data it can hold. All this and more makes it probably not the best for storing data like text, CSV, audio, video or image files. To get around this we could use an SD card to store the data, a ...

DIY Muscle Sensor / EMG Circuit for a Microcontroller

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG systems remain ...

Understanding Flash Memory And How It Works

Flash memory is one of the most widely used types of non-volatile memory. NAND Flash is designed for modern file storage which replaced old disk drives. This article provides a brief understanding of how NAND Flash technology works. The basic storage component used in Flash memory is a modified transistor. In a standard transistor, the flow of current through a channel between two contacts is turned on by a ...

3W 4’x4′ Arduino Laser Cutter/Engraver

https://youtu.be/CbzY5ECsFuQ https://youtu.be/4ybdqgmePDs In this tutorial you will learn how to make your own 4 ft by 4 ft, Arduino controlled, 3 watt laser engraver / cutter (for thin materials) for around 300$. The main thing that separates this tutorial from other laser engraver tutorials on here is the roughly 42 x 42 inch cutting/engraving area. This project arose when I was trying to create a 20 x 15 ...

Tiny FPGA BX – A Tiny, Open Source FPGA development board for Makers

The TinyFPGA boards from Luke Valenty (TinyFPGA) are a series of low-cost, open-source FPGA development boards. These boards offer an inexpensive way to get an introduction to the world of FPGAs. If you have ever considered working with an FPGA before, you will know how difficult they could be especially for those new to the game. TinyFPGA boards are an excellent way to kickstart development with them. They ...

Color Recognition Lock

There are a lot of ways that you can activate an electronic lock. You can use passwords, radio signals, or even voice commands. In this project, I am going to show you how to make a lock box that opens and closes based on color recognition. With a color recognition lock, anything can be a key. You can set the lock to recognize the color of a cereal box, or the cover of your favorite book. You could even use ...

Revolutionizing Electric Field Measuring Techniques

Nowadays, electrical fields are being used not only in electrical engineering, but also for industrial, weather forecasting, safety, and medical applications. As a result, the need for a precise electric field strength measurement device has become increasingly high, and many investigations have devoted their resources to creating such device. TU Wien has developed a small electric field sensor that is much ...

3D Printed Robot

https://youtu.be/AJ1TfieZ6Dg The nice thing about 3D printing is that it makes building robots easy. You can design whatever configuration of parts that you can dream up and have them in your hand virtually right away. This allows for rapid prototyping and experimention. This particular 3D printed robot is an example of that. This idea to have a walker bot that shifted its front center of balance is one tha ...

SODAQ ONE board – GPS + LoRa + Solar charger

Overview: This is the third generation of our succesful SODAQ ONE board. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. It has the Ublox Eva 8M GPS module which is not only miniature but with it's assisted GPS feature it can get a fix within seconds. We've now added an extremely low power Accelerometer/Magnetometer. This gives the board a nifty feature where it can ...
