How To Disable The Red LED On The Pi Camera Module The Pi camera module includes a red LED in one corner of the PCB. This lights up when the camera is active. It’s really useful in giving a visual indication that the camera is doing something and most of the time you will be glad it is there. However there are a number of reasons you might wish it wasn’t. In my testing here are some of the reasons it can get in the way : It can cause reflections on objects you are trying to photograph giving them a red glow.For nature photography it scares animals.For security applications it may draw unnecessary attention to the device.It consumes power.

DIY Productivity Tablet I love my Kindle Fire HD because it is about the size of my old Franklin Day Planner (7") and is an outstanding entertainment device. It lacks a few things, however, that I'd like to remedy. What it's missing is a full desktop OS that lets me get some work done when I'm not at my computer. Using Network Storage on the Raspberry Pi It is highly likely that you are using an 8GB SD or Micro SD card with your Raspberry Pi. This is adequate for many purposes, but if you fully load your Pi with additional applications (see my tutorial on installing more applications on your Pi), you may find yourself running short on space. Of course, you can use a larger SD card, but if you have a Network Attached Storage (NAS) at home, you can access and store files on the NAS. In this tutorial you will learn how to access that external device. Note, however, that there may be differences depending on what device you are using.

RPi SD cards SD cards The SD card is a key part of the Raspberry Pi; it provides the initial storage for the Operating System and files. Storage can be extended through many types of USB connected peripherals. When the Raspberry Pi is 'switched on', i.e. connected to a power supply, a special piece of code called the bootloader is executed, which reads more special code from the SD card that is used to start up the Raspberry Pi. If there is no SD card inserted, it will not start. Install gphoto2 on your raspberry Via the free software gphoto2 it is possible to connect a digital camera (Canon/Nikon/Olympus, full compatibility list) to your Raspberry Pi in order to remotely take pictures and automatically download them to the Raspberry's memory. Easy case You can install gphoto2 very easily via the command line: sudo apt-get install gphoto2

Pi-nk : tutorial Pi-nkAka another Kindleberry Pi tutorial WARNING This tutorial has several important prerequisites. While reaching those, you will void the warranty of your kindle, and might make it unusable and broken beyond repair. If you are not an advanced user, do not try the tutorials below. If, at any time, you do not understand why a particular step is needed, or what it does to the whole system, immediately stop and do research on the topic.

Raspberry Pi Static IP Address & how to configure course Tutorial. The Raspberry Pi is automatically set to obtain an IP address from your wired or wireless network. Why does the Raspberry Pi need an IP address? This address is needed so that any traffic destined for your Raspberry Pi will be able to find it on the network. This is method of obtaining an IP address is called DHCP or Dynamic Host Configuration Protocol. It is sometimes referred to as a dynamic IP. Your router will normally distribute these IP addresses but it isn’t guaranteed that it will get the same IP address every time. Arduino vs. Raspberry Pi vs. CubieBoard vs. Gooseberry vs. APC Rock vs. OLinuXino vs. Hackberry A10 A long time ago, Earth was ruled by dinosaurs. Then they died and we began to play with Motorola HC11. These were prehistoric times, when debugging involved an oscilloscope. (Yes, I am that old.) Then Massimo Banzi invented a new single board: Arduino.

GPS tracking August 03, 2012 at 10:26 PM I thought it might be fun to turn my Raspberry Pi into a vehicle tracker. The nearest I got to building a truly bespoke tracker was in 2004 using a Siemens TC45 & later TC65, where I wrote the firmware. There wasn't really anything on the market then to do what we wanted, so we built our own, and I took care of the software side. Sure there were trackers on the market, but nothing flexible enough to meet our needs for a given application.
