Want to do something fun with your Raspberry Pi?
Why not use an XLoBorg to turn it into a drum kit!
XLoDrum takes the data from an XLoBorg and uses X, Y, and Z movements to represent different drum noises
There are some options you can configure from lines 9 to 18:
...Sampleare the files that will be played for each movement
Intervalis the time between updates
threshold...Highis the G reading at which to fire the sound
threshold...Lowis the G reading at which to reset ready for another movement
Here's the code, you can download the XLoDrum script file as text here
Since we also have sound files the full package is here
The samples were downloaded from Music Radar
To download it directly to the Raspberry Pi use
chmod +x XLoDrum.py
and run using
#!/usr/bin/env python # coding: Latin-1 # Load library functions we want import XLoBorg import time import os # Settings for the drum playing xSample = 'drum-x.wav' # File to play for X movements ySample = 'drum-y.wav' # File to play for Y movements zSample = 'drum-z.wav' # File to play for Z movements interval = 0.1 # Interval to check for movements thresholdXHigh = 0.6 # G required to set a movement X thresholdXLow = 0.1 # G maximum to clear a movement X thresholdYHigh = 0.5 # G required to set a movement Y thresholdYLow = 0.1 # G maximum to clear a movement Y thresholdZHigh = 1.7 # G required to set a movement Z thresholdZLow = 1.1 # G maximum to clear a movement Z # Setup XLoBorg, states XLoBorg.Init() highX = False highY = False highZ = False # Function used to play a sound file def PlaySound(filename): # Build a command and run it command = 'bash -c "aplay %s &> /dev/null &"' % (filename) os.system(command) try: # Loop indefinitely while True: # Read the accelerometer x, y, z = XLoBorg.ReadAccelerometer() # Has X been moved if x < thresholdXLow: highX = False elif x > thresholdXHigh: if not highX: highX = True print 'X' PlaySound(xSample) # Has Y been moved if y < thresholdYLow: highY = False elif y > thresholdYHigh: if not highY: highY = True print 'Y' PlaySound(ySample) # has Z been moved if z < thresholdZLow: highZ = False elif z > thresholdZHigh: if not highZ: highZ = True print 'Z' PlaySound(zSample) # Wait for the interval period time.sleep(interval) except KeyboardInterrupt: # CTRL+C exit, do nothing pass
