How to install OpenCV on Raspberry Pi and do Face Tracking

To  install OpenCV on Raspberry Pi, you need Raspberry Pi ( Pi2 preferably) , Pi camera, and internet connection to  Raspberry Pi.

Begin with latest Raspberry Pi Image from https://www.raspberrypi.org/downloads/raspbian/

Copy this image to correct size SD Card. To do this correctly  please refers these detailed instructions: How to install “Raspbian” on the Raspberry Pi.

Now since your SD card is ready, Boot your Pi. First thing you want to do is  Enable Camera.Read More

Installing Raspbian Lite, Enabling and Connecting with SSH

In this post, I’ll show you how to download and prepare your Raspberry Pi with the latest version of the Raspbian Lite Operating System (OS) and how to establish an SSH communication.

Raspberry Pi and microSD card

The Raspberry Pi is a computer and like any other computer it needs an OS installed.

The Pi doesn’t have built-in memory, so you’ll need a microSD card to install your OS. I recommend using a microSD card class 10 with at least 8GB of memory.

Build a Raspberry Pi Streaming Music Player

In this tutorial, I will be going through steps to making your very own Raspberry Pi music player. This process is pretty straightforward, so you shouldn’t come across any problems at all.

For this project, I am going to be using a pre-built software package called the Pi Musicbox. This software contains plenty of features & functionality that make it great as a Music player.

This project is a headless music player so you will need to use a different device to be able to control it. The good thing is you can pretty much use any device that has a browser to be able to interact with it.Read More

Setup Raspberry Pi Zero with Headless WiFi

The following instructions will work anytime, you don’t necessarily have to follow them for the first boot – this is just a very convenient way to get your Raspberry Pi onto a network without using any plug-in peripherals like a keyboard, mouse or monitor.

What is “headless,” anyway?

A computer setup without a monitor is said to be running headless. You might want to do this if you’re installing your Pi into some project, or want to keep power-usage and cost minimal. This kind of setup is what the Pi Zero W was built for. The idea is that you can still access your Pi’s terminal interface over your network using a protocol called SSH.

All we need to do is get our Pi set up with the right WiFi credentials and we’ll be able to remotely access it through a terminal program, as if we were using the terminal Pi’s own desktop. What’s more, we’ll get our Pi connected to WiFi without ever having to plug in a monitor, keyboard or mouse to configure it.Read More

Voice Typing using Raspberry Pi and Android App

You must have familiar with Voice typing, which is very commonly used in Computers and mobiles phone, where you can type any word by speaking it. Voice typing is very useful for handicapped person or for anybody who wants to type fast. So today we are implementing the same on 16×2 LCD Display, where the voice text will be displayed on LCD. Here we have used 16×2 LCD, but this setup can be installed at many places with a bigger display to broadcast any message, like at airports, malls, offices etc.

In this project we will provide the input voice using Google Voice Keyboard via a Android App (BlueTerm) and print the text on 16×2 LCD using Raspberry Pi. Here we will type the text on 16×2 LCD using wireless Bluetooth Medium and will use USB Bluetooth dongle with Raspberry Pi. So basically we need interface the 16×2 LCD with Raspberry Pi and setup the Bluetooth in Raspberry Pi to receive the data sent by Mobile phone. Read More
