Impress your friends (especially the nerdy ones!) and challenge yourself to memorize as many digits of pi as you can.
APP USERS PLEASE UPLOAD YOUR FAVORITE PROJECTS!
The screenshots only show the initial projects I posted. I need YOU to post some more projects for everyone to see and possibly attempt themselves! There are many Pi users that will get use out of the project(s) you post! We all thank you!

Application note that this is NOT official, therefore it is external to the brand Raspberry Pi and for use solely for educational and personal purposes.
It has informed the foundation R. P. on the development of this app and have decided to rename and modify some content to clarify that has nothing to do with the brand itself to avoid confusion!
IT's FUN! Control your phone or tablet, and then to control your electronics projects with it?
Let's see, how do I convince you to install BTInterface?
Well, without controlling anything if you just install BTInterface on your phone and tell your friends the SMS password which by default is the three letter word 'bti' then they can send texts to your phone that begin with bti to make it speak, play sound effects, display things etc. :) It might be interesting to see what they come up with!
Come join my forum at
for more secrets!
BTInterface acts as the ‘buttons’ and the 'display' to your device! but it's so much more!
Now also works with PCs and Laptops! See this forum thread:
By using a wireless bluetooth module, dongle or built-in bluetooth you get wireless working plus a controller with great features that is simple and easy to use and to program.
Developers can sell their devices and tell the user to download BTInterface to control them!
They can also add wireless Bluetooth control to their software projects!
All the control functions including screen, sound, send/receive sms text messages etc. are already catered for so the developer can keep the cost and complexity down.
Also great for education!
Features such as send SMS Text messages? How hard would that be do you think? Well, from your micro controller device you send this text string over the bluetooth connection:
sms 01234567 this is a message from my micro controller!
Another command is 'say' and it will cause the android device to speak.
say Hello, thank you for trying bee tee interface.
BTInterface can act on incoming SMS text messages too! If they begin with the password BTInterface will take the message (it doesn't get to your normal messaging app) and act on any commands in it so in this way you can remotely control your device from any mobile phone that can send texts from anywhere in the world!
Other commands configure the screen so its just as you want it, play sound effects, hide BTInterface to the background, bring it back again, even if you put the android device in to sleep mode (screen is black) BTInterface is still working and if your micro controller sends the command:
say I'm still here you know.
it causes your android device to speak even though you thought it was turned off :)
If you load up BTInterface onto a device that has phone functions, ie: it can receive SMS Texts then you can try it out without needing any micro controller because BTInterface can work on commands that you send it in a text message!
Tremendous fun, easy to use. Try it out the beta trial is free!

Put out a blazing house on fire! Pull into and out of the fire station. Race the Fire Engine around a race track. Work your way through traffic on city streets! Hours of fun and entertainment. This app guaranteed to helps your child create wonderful stories in their mind of being a heroic fireman or firewomen.
Simply touch and drag the fire engine around the screen. As you change directions, corner or curve it makes a tire squealing sound. The fire engine makes two different siren sound sequences.
If you let it go on its own it will cross the screen and come out below bigger. It will do this and get bigger three times then repeat the cycle. As you drag it will change directions based on the direction of dragging.
The background changes on preset amounts of touching per screen. Play with it awhile and the scene will change. There are five scenes, each with a different preset touch amount for changing scenes, depending on the adventure.
Landscape gives the best effects but it can be used in portrait mode. App stops sound and motion when changing orientation or when interrupted by phone call, etc. It goes into pause mode.
