If you're having a party or other event, the concept of having a photo booth is increasing in popularity. If you think this would be fun, or just because you can - then check out this project by Instructables member SWJTUyuhui. They show how simple and easy it is to use a Raspberry Pi, matching camera, power supply and a colour inkject printer as an instant photo printer system.
Furthermore with the use of a sound sensor module, the camera can be activated by noises of certain levels. For example, people may need to shout to get it to work, or just say "print!" - it's up to you.
If you're buiding the photo printer above - or interested in experimenting with sound and your Arduino or other development board, our Freetronics MIC: microphone and sound module is perfect.
The MIC: contains an integrated dual signal amplifier converts the sound to separate channels for pulse / frequency measurement, and sound volume (pressure) level. Designed to connect straight to an Arduino compatible microcontroller, Analog to Digital converter, or many other circuits. For more information and to order click here.
