Hi! First thing I got in mind when seeing Raspberry PI was "car PC project". The targeted display was 7 inch with touchscreen. I have found a lot of displays on Ebay. I have got myself one for 85 dollars with free shipping(this; if it is not available any more you can search "reversing driver board hdmi" on ebay and you will find others). The display driver board has hdmi input and an on board resistive touchpanel with usb controller board. It took less than a month to receive it(in Romania). After unpack, it worked out of the box with Ubuntu 12.10(display + touchpanel) and with Windows, but for Windows I had to install some drivers also received in the package. I have installed latest Raspbian image on a SD_Card and tried it on my Raspberry PI model B, but the touchpanel didn't show any input.
First thing, I have run lsusb to see the touch controller type(on RaspberryPI): pi@raspberrypi ~ $ lsusbBus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.

Touchscreen on the Raspberry Pi | Mark's space dot com. To accept input from a touchscreen we have to use the event interface of the Linux input system. We use the ioctl capabilities of the event interface, in addition to the normal read and write calls to get information from the touchscreen. This blog post explains how to use the touchscreen within your own programs using C as well as writing directly to the framebuffer. Images of my TFT from a previous post; Link to the code; The touch screen I have is a 3.2″ TFT from SainSmart. Linux Input System To accept input from a touchscreen we have to use the event interface of the Linux input system. To view the input devices on your system, use cat /proc/bus/input/devices Below is the output from my Raspberry Pi.
The above output shows that the handler for my touchscreen is event0, or “/dev/input/event0″. An example ioctl is shown below, this gets the name of the device using EVIOCGNAME. The above features are listed in linux/input.h as; The Code. How to Make a Raspberry Pi Media Panel (fka Digital Photo Frame) The goal of this project was to create a low cost Raspberry Pi Media Panel--a nice looking screen that could stand in the living room or attach to the refrigerator with the primary purpose of streaming personal photo and video content full time, but also be able to do some other cool things when needed...like show the weather, play a movie, play music, or receive AirPlay content.
Read this blog post if you want to learn more about what a media panel is and why you might want one. Success criteria were: -Low cost: a full blown computing device and screen for between $100 and $200 all in -Attractive: meaning my wife finds it aesthetically acceptable for the living room -Light: no more than a few pounds -Thin: no more than an inch thick, including frame -Quick: can be built in a few hours or less -Simple: requiring mainly assembly, versus construction or manufacturing Update: Several people have asked me about an integrated product/service like this that is off-the-shelf.
We call it Fireside. 25 fun things to do with a Raspberry Pi. Raspberry Pi GPIO home automation. LittleBox | The DIY Raspberry Pi All-In-One Desktop PC by Gregory L Holloway. The LittleBox is designed to be built at home, by anyone, and with the minimum of tools. Everything you need to turn your Raspberry Pi into a Desktop PC is included as part of the complete LittleBox kit. I am a huge fan of the Raspberry Pi. It has sparked a revolution in the computing world, and has inspired millions, including myself. The LittleBox is the culmination of 18 months of working with the Raspberry Pi.
The idea for the LittleBox comes from my involvement with the FishPi Project where we are moving towards building an autonomous drone, controlled by a Raspberry Pi, which will cross the Atlantic Ocean. We have a Base-Station which is used to control and monitor our Proof-Of-Concept Vehicle, and I wanted everyone to be able to share in the experience. The LittleBox was originally conceived as an at-home version of the FishPi Base-Station, but the idea has grown into something far greater. The 61 Laser-Cut parts are are produced from a single sheet of 3mm Birch plywood.
