This project uses OSC(Open Sound Control) iPhone/iPod touch and DMX to control a lighting rig. It doesn’t require a computer once you upload the necessary sketch to the arduino.|link|
Very cool project by Nick.
This Message queue monitor project sent by Alex Kane.
This is a gadget I made to tell me at a glance the size of the various message queues that I manage at TuneCore. It sits on my desk next to my monitor and tells me right away what’s going on with our delivery system. A steady light means the queue is not very long; a rapidly blinking light means that the number of items in the queue is very large and it needs attention.
This project is an Arduino based step sequencer, synthesizer and sound effects box.
The user interface is kept very simple, with just four knobs, three push buttons, 8 LEDs and a power switch. The speaker is connected straight to a pin on the Arduino via the volume knob - everything is done in the Arduino using PWM to generate analog waveforms. The LEDs indicate the current step in sequencing mode, and provide light patterns in noise modes.
The basic features are:
16-step programable sequencer with adjustable frequency and duration for each step
synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
noise generation (sirens, laser beam, random noise)
Mike McRoberts sent me the unique concept clock using an8×8 RGB Dot Matrix Display.
The time is indicated using blocks of colour. The central 6×6 grid is split into 4 x (3×3) grids and each 3×3 block is a different colour. The number of LED’s per 3×3 grid indicate the digit. i.e. if the first 3×3 grid has 1 LED lit then the first digit is 1, the second has 7 then the 2nd digit is 7, etc. The top two grids are the hour digits and the bottom 2 the minutes. Around the edge the unused LED’s have a moving light that shows the approximate position of the seconds.
