A Device to create, collaborate music

This is a final year project by students of Cornell University which permits companions to learn melodies, make their own particular tunes, and collectively consolidate them. There are basically two pedals each having eight sets of fully customizable buttons and any button can be used to play and MIDI sounds. The device also allows you to record your music in real time and also offer functionality for playback. However, the different feature of this device is its ability to transfer music to your friend which can then merge their melodies with yours. The transmission takes places through a set of IR transmitters and receivers There is also a teacher mode which allows you to practice playing pre-programmed songs. The prototype uses pulse-width modulation and direct digital synthesis to play back… Continue reading

Probably the simplest 3 channel IR remote control

This is a simple 3-channel remote control project developed by sixca. It uses two PIC12F629 microcontrollers for both sides: receiver and transmitter.   Remote control is based on RC5 protocol which is most popular among manufacturers and hobbyist because of its simplicity. Transmitting is done by pressing one of three buttons representing channels. Rx side has IR receiver which decodes transmitted signal and gives logical “1” outputon one of three pins. These pins can control anything including relays, lamps, motors and other external devices. You may expand functionality by modifying source code. Continue reading
