 To stream to the Blinkenwall from your computer, open http://10.20.30.26/cgi-bin/togglesocket.cgi and wait for the test frame to appear, then send RGB data for the 45 pixels as before, but without the PPM header (9*5*3 = 135 bytes per frame). Open the URL again to switch back to animations.
+=== Wiring ===
+Since the Raspi got accidentally disconnected and there was confusion on how to wire it up again, here is how:
+* Look at the [http://elinux.org/images/2/2a/GPIOs.png Raspi model B P1 header pin configuration]
+* Think of the wires of the ribbon cable connecting to the wall as numbered from R1 to R6, where R1 is the red wire and R6 is the blue wire. Connect the orange wires labeled 2 to 5 to the corresponding wires R2 to R5.
+* The big power supply has two wires, a dark blue one and a grey one. Connect the dark blue wire to the blue wire (R6) on the ribbon cable.
+* Connect the other connector on the dark blue wire to a ground pin on the Raspi, e.g. pin 6.
+* Connect orange wire 2 to pin 23 (SCLK) on the Raspi.
+* Connect orange wire 3 to pin 18 (GPIO24) on the Raspi.
+* Connect orange wire 4 to pin 22 (GPIO25) on the Raspi.
+* Connect orange wire 5 to pin 19 (MOSI) on the Raspi.
+* Connect the red wire on the ribbon cable to the big power supply's grey wire (labeled 1).
