Step 2Select Your Power
On the lower right corner of the board is a collection of spots for diodes, along with a jumper labeled 'USB Only'. All of the power to the board comes from this area.
If you are using an original Cthulhu, for Playstation 3 or PC USB only, then your kit should not have come with any diodes. In order to make sure your board gets power, you need to solder together the two points labelled 'USB Only', pictured in the first image. This is very easy to handle but still must be done. Heat up your soldering iron, and prepare to get messy. Melt an obscene gob of solder on the end of your iron, and use it to connect the two pads of the jumper labeled 'USB Only'. Keep going until they're connected. The second picture shows a completed jumper.
If you are assembled a multi-console 'MC' Cthulhu, your kit should have come with four diodes; two glass, and two larger black diodes. Before we install them, we need to make sure we put them in properly; if they are put in backwards, it won't cause any bad problems, it just won't work, so let's get it done right the first time.
Look are the first image, in particular at the white rectangles labeled 1 through 3. You'll notice there is a band on the image, on the end of the rectangle closest to the spot in between all of the diodes. Check both your glass and black diodes; there are similar bands present there; black on the glass diodes, and a white or grey on the black diodes. When you install the diodes, the bands MUST be on the same side of the diodes as shown on the silkscreening. The 'USB Only' jumpers cover where the rectangle should be for that spot; that's fine. The orientation is the same as the #3 diode beside it. The bands always go on the end closest to the middle of all four diodes.
Take your glass diodes, and lightly bend the legs down. Take the first glass diode, and insert the legs through the holes on either side of the 'USB Only' jumper. Pull the legs through so the diode is flat against the board, and bend the legs out from the bottom to hold it in place. Take a moment to look at the diode and make sure the band is on the same end as shown in the silkscreen for #3.
Take the second glass diode, and insert the legs into the holes on either side of the #3 silkscreen. Check that the band is on the proper end, same as the first diode. Bend the legs out to hold it in place. Flip the board over, solder all four legs, and clip off any extra wire from the legs.
Take the two black diodes, bend the legs, and insert them into diode spots #1 and #2, making sure the band is on the same side as shown in the silkscreen. I will warn you, the holes are barely bigger than the legs. On all of them I've done, I've had to poke the legs through a little and use a pair of pliers to pull the legs the rest of the way through so the diode lies flat against the board. Once they are flat, bend the legs out to hold them in place, flip over, solder and trim.
If you are converting a PS3 Only Cthulhu to a MC Cthulhu, use your soldering iron to melt the solder on the 'USB Only' jumper so it no longer shorts the two jumper pads. Once that is done, install the four diodes as described above.
NOTE: If you are converting a PS3 Only Cthulhu to a MC Cthulhu, and the Cthulhu board is the 1.4 revision (listed on the bottom of the board) that already has four black diodes installed, do NOT do any soldering or desoldering. Simply swap chips and your Cthulhu is upgraded. The instructions above assume you are using a Cthulhu board that does not have the diodes already.
