DIY Mini Quadcopter with 3D-Printed Frame and Custom Firmware

I wanted to try my hand at a true "DIY" project, designing and building my own micro quadcotper frame and writing my own firmware in C++.  In this post I will describe the frame and build; in my next post I will talk about the firmware. Excluding stuff I had lying around the shop, (heat-shrink tubing, EC-3 connectors, velcro, cable ties, etc.) the cost came to just under $170: 3D-printed frame "free"! Fligh ...

IBM scientists achieve storage memory breakthrough

The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry's attention as a potential universal memory technology based on its combination of read/write speed, endurance, non-volatility and density. For example, PCM doesn't lose data when powered off, unlike DRAM, and the technology can endure at least 10 milli ...

DC Motor Speed Control using GY 521 Gyro/Accelerometer and Arduino

In this article, we are going to control two motors by using the GY-521 accelerometer module. The speed of the motor will increase or decrease upon moving the GY-521 module up or down. On moving the Gy-521 towards the downside, the speed of the first motor will decrease and the speed of the other motor will increase; while on moving the GY-521 towards the upward side, the speed of the second motor will decr ...

Codename RGB

Remotely control your RGB LED strip from your pc. Things used in this project Hardware components Arduino MKR1000 × 1 Power MOSFET N-Channel Might be something similar. × 3 RGB Led Strip Make sure its 12v dc (if Its not 12v you will have to have a power supply with the same voltage as your strip.) and also that its pins are in the following order: VCC, B, R, G. If it isn't in that order you'll have to modif ...

Interfacing 8×8 LED Matrix with Arduino

LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display a few characters in it. 8×8 matrix consists of 64 dots or pixels. There is a LED for each pixel and these LEDs are connected to total of 16 pins. You can identify the pin ...

Automatic Irrigation System using Arduino

In this project, we are going to build an automatic irrigation system using Arduino which senses the moisture of the soil and opens or closes the valve according to the moisture value. The moisture value and the valve status is shown on the Nokia 5110 LCD display. Before we proceed, let’s take a look at another project – a plant watering system using Arduino, which is very similar to our application. You ma ...

Spinning or Rotating LED Display using Arduino POV

Designing a Spinning/Rotating LED Display In this project, we are going to show you how to make a simple “Rotating LED Display”  (also popularly known as Spinning LED Display) with Arduino. The motivation to make this project came to my mind when I saw a product in the market, in which a text message was clearly visible on a “Rotating LED Strip”. After that, I planned to make this project myself and Arduino ...

ODrive – High performance motor control

Description Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to air hockey and juggling robots use them. However in industrial automation, brushless servomotors have taken over, and it's clear why: They don't lose steps, are much more powerful, efficient, ...
