Notes

In this example, I pass the parameter “card=42″ to the module “saa7134″ when the module loads at boot time.

1. Add your module to /etc/modules

   
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules
# that should be loaded at boot time, one per line.
# Lines beginning with "#" are ignored.
saa7134


2. Add options saa7134 card=42 to the end of /etc/modprobe.d/options

   # Enable double-buffering so gstreamer et. al. work
options quickcam compatible=2

   # Default hostap to managed mode
   options hostap_pci iw_mode=2
   options hostap_cs iw_mode=2

   # Stop auto-association.
   # LP: #264104
   options ipw2200 associate=0

   # XXX: Ignore HPA by default. Needs to be revisted in jaunty
   options libata ignore_hpa=1

   options saa7134 card=42

Now reboot and you should be all set.

1. Add your module to /etc/modules

   # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. saa7134

2. Add options saa7134 card=42 to the end of /etc/modprobe.d/options

   # Enable double-buffering so gstreamer et. al. work options quickcam compatible=2
# Default hostap to managed mode options hostap_pci iw_mode=2 options hostap_cs iw_mode=2
# Stop auto-association. # LP: #264104 options ipw2200 associate=0
# XXX: Ignore HPA by default. Needs to be revisted in jaunty options libata ignore_hpa=1
options saa7134 card=42

GLOBALSAT BU353 Waterproof USB GPS Receiver

GARMIN 010-00321-00 GPS 18 Deluxe USB Sensor

The Globalsat BU-353 would be my first choice, it has very good reviews and it is waterproof.

There are only 3 files you need to backup:

• signons.txt
• signons2.txt
• key3.db

You can find those in your Firefox profile:

Linux

~/.mozilla/firefox/xxxxxxxx.default/

Windows

1. Click the Windows Start button, and select Run….
2. Type in %APPDATA%\Mozilla\Firefox\Profiles\ then click OK.

You can then copy those file to another computer in your Firefox profile to use them.

The instructions for this project are incomplete, but you basically step on the circuit on each tile with a conductive sole shoe (you could use aluminum tape glued under your shoe) to close the circuits. I hope to be able to add more detailed instructions and pictures soon. For now, you can check out http://royconejo.host.sk/, it was heavily inspired from it.

WARNING: Before anybody attempts to build this dance pad, please note that after a while I suddenly started having intermittent problems (it stops working). If I unplug it and plug it back, it starts working fine again for a while. I think the problem is caused by the wires connected to the circuit board being too long. It might change the inductance and/or capacitance too much and the circuit board can’t handle it. I don’t know much about electronics so If anyone know how to fix this, please let me know. I tried with a USB circuit board and a USB board with a PS/2 adapter without any luck.
