Easy To Understand Raspberry Pi GPIO Pin Layout Diagram

One of the major strength and a reason for Raspberry Pi success has been the General Purpose Input/Output (GPIO) access offered by the mini computer, these programmable in/out pins allows a great of hackability letting users expand the system and get it interacting with other hardware devices. The GPIO pin's are confusing as they are not numbered serially, here are two nice RasPi GPIO pinout layouts for making things easier to understand.

Using Full 40MHz WiFi Channel Width In 2.4GHz Spectrum On Apple Mac

Yesterday, we shared a tip to make use of an external USB WiFi adapter on Apple Mac computer's for better wireless experience. Luckily, the experiment Killed Two Birds with One Stone as it made the 40Mhz wide WiFi width usable in 2.4Ghz spectrum which is not made available with the built-in WiFi card. As evident from the screengrab posted below, the external USB card also makes use of full 300Mbps bandwidth resulting in faster file transfers over wireless link.

A guide on how to install and use external USB Wifi adapter on Apple Mac and extend wireless coverage

Apple iMac and Macbook's built-in wireless card is known to have limited coverage as it does not feature an external antenna for better signal reception, however we can easily boost the Wi-Fi signal strength and range of any Apple Mac computer using external USB wireless dongles with external antenna. To get this working make sure you have an WiFi USB Adapter which is compatible with Apple Mac OS X and have drivers available for it, luckily for me the Realtek 8191 Chipset based Mini 300Mbps USB Wireless Adapter we used earlier to hack and make Asus O!Play wifi capable did the trick.

Once you have your wireless usb adapter connected to the Mac we need to identify it and install the correct driver for it, We will be using the Mac OS X "System Information" utility (find via spotlight search) to get our hardware information as shown below.

Solution for iMac's inability to connect with WiFi 802.11n only access point

Tweaking your WiFi configuration for maximum throughput sometimes have adverse side-effects, we have already seen how changing your WiFi channels can create problems with non-standard or incompatible WiFi cards.

Having customized your WiFi config can also create strange problems like WiFi being visible and connectable but with limited functionality and no web-browsing. As evident from the screenshots on the right and below my iMac running Mac OS X 10.8.2 is having issue communicating with my router, after researching over the internet reading numerous forums and help articles I finally figured out the solution experimenting with my router config.

This Nifty Little Trick Allows Users To Share Single Earphone With Two Different Music Streams For Each Earbud

The "There's An App For That" tagline once again proved to be very much correct, since we now have a free app which allows Apple iOS users to share their earphones with anyone nearby while each listening to different tracks at the same time. Splitr gives users two independent music players, each earbud (left and right) can not only stream two different music files but also allows independent volume controls. The application interface is as simple as it can get, with all controls splitted on the main screen for quick access as shown below.

Pidora - Fedora Remix Optimized For Raspberry Pi Now Available For Download

While users can easily install and use multiple operating-systems on Raspberry Pi using BerryBoot, the beauty of an removable media card as operating-system loader is the simple plug-n-boot ease of use. The official Debian Linux port is the most widely used and supported distribution for Raspberry Pi, but specialized OS like RasPlex, Xbian and Raspbmc are also available for download with more and more Linux distributions getting ported for the platform by the developer community. Adding another excellent addition to the ever growing list of dedicated, RPi optimized builds of various Linux distributions; Fedora joined the club with release of Pidora - a Fedora Remix optimized build for the Raspberry Pi computer.

Pidora is an RPi optimized build of Fedora (Fedora Remix) featuring software packages from the Fedora Project compiled specifically for the ARMv6 architecture for use on the Raspberry Pi. Unique features of this build are Graphical firstboot configuration (with additional modules specifically made for the Raspberry Pi), Compact initial image size with auto-resize for maximum storage afterwards, unique feature allowing IP address information readable over speakers and flashed with the LED light for true headless mode on setups lacking a monitor or display, easy package management using Yum, included support for programming languages (like C, Python, & Perl) and libraries capable of supporting external hardware such as motors and robotics (via GPIO, I2C, SPI) out-of-the-box.
