+====== Wiimote ======
+I've wanted to use my Wiimote to control my PC for some time now, and finally got around to trying it all out.
+Getting the wiimote connected to my PC was easy - just install ''wmgui'', a little GUI app which demonstrates connectivity (via ''libcwiid1.so'').
+There's also a package called ''wminput'' which probably does what most people want - it turns a wiimote into an X11 input device (e.g. mouse) so you can point to move the mouse around. You have to ''sudo modprobe uinput'' first on Ubuntu 9.04, btw.
+===== Doing it myself =====
+I wanted to play with it myself, so I installed ''python-cwiid'' and messed about with a Python script until I got the hang of the API(([[http://wiki.wiimoteproject.com/Reports|WiiMote Project.com]] was useful in working out the API)):
+<code python>
+#!/usr/bin/env python
+# Wiimote experiments. Hopefully this'll grow into something I can use with
+# wminput (or emulate it to the same affect)
+import os
+import sys
+import time
+import cwiid
+wiimote = None
+print "Press 1+2 on the Wiimote now..."
+while not wiimote:
+	try:
+		wiimote = cwiid.Wiimote()
+	except e:
+		print e
+		print "Ignoring previous exception"
+		time.sleep(0.5)
+wiimote.led = cwiid.LED1_ON | cwiid.LED2_ON | cwiid.LED3_ON | cwiid.LED4_ON
+wiimote.rumble = True
+time.sleep(0.4)
+wiimote.rumble = False
+wiimote.led = cwiid.LED1_ON | cwiid.LED4_ON
+print wiimote.state
+wiimote.enable(cwiid.FLAG_MESG_IFC)	# "if changes"
+wiimote.rpt_mode = cwiid.RPT_BTN
+while True:
+	messages = wiimote.get_mesg()
+	for mtype, m in messages:
+		if mtype == cwiid.MESG_BTN:
+			for x in dir(cwiid):
+				if not x.startswith("BTN_"): continue
+				if eval("cwiid.%s" % x) != m: continue
+				print x
+				break
+			if m == cwiid.BTN_A | cwiid.BTN_B:
+				print "A + B, exiting"
+				wiimote.disable(cwiid.FLAG_MESG_IFC)
+				wiimote.rpt_mode = 0
+				wiimote.close()
+				exit	# Causes a segfault.. (why?)
+		elif mtype == cwiid.MESG_ERROR:
+			for x in dir(cwiid):
+				if not x.startswith("ERROR_"): continue
+				if eval("cwiid.%s" % x) != m: continue
+				print x
+				break
+		else:
+			for x in dir(cwiid):
+				if not x.startswith("MESG_"): continue
+				if eval("cwiid.%s" % x) != mtype: continue
+				print x
+				break
+</code>
+Next I need to workout how to inject things into X11, probably via ''/dev/misc/uinput''. I think [[http://www.koders.com/python/fidAC06355D48C7BA355686BC67E42D0C7B09CD7FEA.aspx|this snippet]] will be invaluable.
