== HSW-001 ==
All LED's on the switch board are turned on/off either by syscon or by the BD drive by using an intermediary transistor that drives the LED ground pin (and the other pin of the LED's is connected permanently to the 5 volts standby line present in the switch board at all times). All LED's have its own resistor with a different value to control the current (thus light intensity) and one or more diodes to protect the circuit

When Power and/or Eject switches are pressed the correlating syscon pins are pulled down (grounded)

== Contour backlight in PS3 2000 Series boards ==
PS3 2000 series ([[CECH-20xx]], [[CECH-21xx]], and [[CECH-25xx]], with Switch boards DSW-001 and HSW-001) has been designed to have a lighted line all around the top edge of the Switch board

'''Light rays bouncing surfaces, and light reactive materials'''
<div style="float:right">[[File:Power Eject board PS3 2000 series (light rays schematic in contour leds).jpg|500px|thumb|left|Switch board PS3 2000 series<BR />Light rays schematic in contour leds]]</div>

The plastic plate uses a "light reactive" material along the edge and in a squared hole in the corner allows the light to "transpass" it

The ligth rays "bounces" inside this material, and the first bouncing surface over the squared hole is a plane at 45 degrees angle. This first bounce aligns the light rays in paralell to the board, the next bounces happens all along the curved surface in horizontal

The reflection of this surfaces can be increased a bit with chrome stickers (or alluminium tape). The case has a plane border of 3,5mm x 17,7cm perfect to stick in it, this way the glue layer of the sticker is at the other side, but the case doesnt have the 45 degrees surface (it has a weird hole instead), you can use other colors for the sticker/s because the color is partially visible from outside (preferably lighter colors or one that matches your led/s color to enhance it)

=== HSW-001 Contour backlight enabled bypassing the transistor ===
'''Contour LEDs subcircuit'''
<div style="float:right">[[File:Power Eject board HSW-001 (Contour LEDs subcircuit, unpopulated components).jpg|500px|thumb|left|Switch board HSW-001<BR />Contour LEDs subcircuit, unpopulated components]]</div>
In HSW-001 board there are 2 leds connected to 2 resistors, 1 zener diode, and 1 transistor (and unpopulated solder points for another similar group of components) all this subcircuit is driven from PIN1 line in the connector

Why is this subcircuit present in this Switch boards is a mystery, obviously it was designed to be lighted but at some point somebody declined the idea (maybe poor lighting, maybe too scandalous for sony taste, who knows)... the point is the the line is cutted in the motherboard, and half of the components are missing so this contour backlight is disabled from factory

The subcircuit is activated by the transistor base pin that goes in-line with the other unpopulated transistor base pin, both does the same function at the same time, each transistor is in chargue of 2 leds with a common zenner diode (the transistor opens/closes the leds ground lines, and when the line is opened the zener diode works as an "voltage regulator" for the subcircuit avoiding "voltage peaks"). These transistors are "isolating" the subcircuit at his left

The unpopulated resistors values are dependant of the leds added

'''Minimal parts version'''
<div style="float:right">[[File:Power Eject board HSW-001 (Enabling contour LEDs, minimal parts version).jpg|500px|thumb|left|Switch board HSW-001<BR />(Enabling contour LEDs, minimal parts version)]]</div>
With this method, all the ground pins of the background light LED's are joined together and switched at the same time (4 white LED's from power/eject buttons + the LEDs present in the "contour backlight" subcircuit)

The wire is bridging the connector PIN3 (that switches on/of the backlight for power eject buttons) to the collector pin of the transistor, but also is connected to the collector pin of the other unpopulated transistor, this means all the 4 LEDs of the subcircuit (in the case of adding the 2 missing LEDs with his 2 resistors) will be activated at the same time by the wire, and has a common zenner diode to protect the 4 LEDs lines from voltage peaks

The transistor function is bypassed by this wire so the area at the left of the transistor/s is not an isolated subcircuit anymore, this can be a problem for the total current of the board and for this reason in the photo there is an "optional" cutted line to disable the white leds for power eject buttons (you are adding 4 leds, so other 4 "needs" to be disabled to ballance the karma)

In the case the transistor is activated (seems not posible because the trace is cutted in motherboard) the collector pin (ground for leds) is connected to the the emitter pin (common ground of the Switch board), this doesnt interferes with the added wire because the PIN3 line is doing the same function (with another transistor in the motherboard)

The top-left LED (red) ground is connected to this tiny black component in verticall that is a '''HUGE 3K {{ohm}}''' resistor, the value of the resistor makes the red light almost not visible, so is a good idea to remove/replace the resistor or to remove the red LED, removing LEDs can be convenient because are different colors (better use one colored LED + 3 whites... or 4 of the same color)

To remove a resistor so tiny with a solder iron there is a trick using a melted drop that connects both pins of the component and when all is melted you move the component laterally. If you try to remove a LED of this size with a solder iron his plastic cover will "pop up" in 100% of the cases, if you dont plan to recycle the LED this is not a problem, first you destroy/popup the plastic cover of the LED with the solder tip and then you can use the trick of the melted solder drop, the only caution needed is to dont damage other nearly components and use a good solder iron with a 0,5mm tip or so

*Variations (Contour LEDs are separated in 2 groups, turned on/of by 2 separated ground lines... in this list are defined as "group1" and "group2")
**1 wire (both groups grounds driven by 1 wire)
***Wire connected to PIN3 (power/eject buttons white backlight)... 4x contour LEDs are ON when/while PS3 is turned on (is the circuit proposed here as "minimal parts version")
***Wire connected to PIN7 (Power ON dual LED, green color)... 4x contour LEDs are ON when/while PS3 is turned on (with a "triple blink" when turned ON/OFF)
***Wire connected to PIN8 (Standby dual LED, red color)... pointless and annoying, contour LEDs will be permanently ON and there is a better way to achieve this
***Wire connected to PIN9 (Eject LED, blue color)... 4x contour LEDs are ON while there is a disc in the drive, and does a "triple blink" when loading/ejecting a disc
**2 wires (this implyes adding the unpopulated resistors and LEDs, and using 2 wires to separate the LEDs in 2 groups)
***Wire 1 connected to PIN3 (power/eject buttons white backlight), and wire 2 connected to PIN7 (Power ON dual LED, green color)... group1 is ON when/while PS3 is ON (for a total of 50% light intensity), and group2 does a "triple blink" and stays ON (for a total of 100% intensity)
***Wire 1 connected to PIN3 (power/eject buttons white backlight), and wire 2 connected to PIN9 (Eject LED, blue color)... group1 is ON when/while PS3 is ON (for a total of 50% light intensity), and group2 does a "triple blink" when loading/eject a disc or stays ON while a disc is inserted (for a total of 100% intensity)
***Wire 1 connected to PIN7 (Power ON dual LED, green color), and wire 2 connected to PIN8 (Standby dual LED, red color)... there is a better way to activate a group for standby, and group2 does a "triple blink" when loading/eject a disc or stays ON while a disc is inserted (for a total of 100% intensity)... but you have replicate the dual function of the Standby/Power ON dual LED, this means you have all the output for homebrew apps thas uses these LEDS like "fan controll utility" and even error codes like the YLOD
***Wire 1 connected to PIN7 (Power ON dual LED, green color), and wire 2 connected to PIN9 (Eject LED, blue color)... group1 is ON when/while PS3 is turned on with a "triple blink" when turned ON/OFF (for a total of 50% light intensity), and group2 does a "triple blink" when loading/eject a disc or stays ON while a disc is inserted (for a total of 100% intensity)

=== HSW-001 Contour backlight controlled by teensy ===
This mod is only for the permament installations of teensy, teensy has an onboard led (connected to D6 data line in teensy PCB) when teensy is installed in a permanent way inside PS3 is not posible to see the activity of this led

The mod consists in connecting the teensy led output to PIN1 of the CN_SW_1 connector that drives the "contour leds", this way our "custom signal" will travel along the official ribbon cable that connects the PS3 motherboard with the switch board

PIN1 of the CN_SW_1 connector is connected to syscon PIN 12, this is the original circuit because syscon was supposed to drive the contour leds, but it seems nobody found how to make syscon output a signal by that pin, is completlly inactive as far scene knows, maybe is used for some special factory mode, who knows, but by now looks useless

At the other side of the PS3 motherboard, exactlly under the CN_SW_1 connector there are some pads and vias that belongs to the connector, one of them is for PIN 1 of the connector and has a pad good to solder in it, this is where teensy needs to be connected with the trace

The problem needed to solve is this same trace is connected to syscon PIN 12, and we dont want to send voltajes to syscon, right ?, so is needed to cut the trace that goes out of PIN 12 of syscon, you can cut it at any point near to syscon

After all this has been done, teensy is going to send a voltage control signal to the switches board, by using PIN1 of the connector, this voltage signal controlls a transistor (actually 2 transistors, but one is missing) that does the led switching

The two transistors in the switch board has a line conecting them by its bases (this means both does the same), and every transistor controlls 2 leds... for a total of 4 leds

There are 2 ways to control the leds that looks handy, the simple one is to dont cut the line in between the transistors, so the leds are lilghted only when the teensy sends the "blink" voltage control

The other way is by cutting the trace in between the transistors, to separate them in 2 groups, one group will be enabled by the teensy as just explained, and the other will be permanentlly enabled while PS3 is ON by connecting the base of his transistor permanentlly to the 5v line of white leds

The behaviour of the last explained mod is 2 leds will be lighted when console is ON (when the white backlight of power/eject buttons is lighted), and the other 2 leds will be controlled by teensy, if you use 4 leds of the same colour most of the time the leds will be lighted at 50% and when teensy "blinks" at 100%, if you use 2 leds of a color (as example 2 blue) and 2 leds of another color (as example 2 red) you could have a base colour that is used when PS3 is ON (2 blue) and when teensy "blinks" the resulting colour will be a combination of colours (2 blue + 2 red = purple)

Another option using blue as an example: the base group with "2 blue" and the teensy group with "1 blue + i white", so base colour is a 100% pure blue, and when teensy "blinks" results in the same blue colour but with more intensity and more brightness

=== HSW-001 Contour backlight leds repurposed to a thermal display ===
This is more complicated, it needs a microcontroller like a PIC with 2 thermal sensors for CELL and RSX (or hook the signals of the onboard thermal sensors from the the PS3 motherboard), and with 2 control pins for leds

One of the pins of the microcontroller controlls a group of 2 blue leds, the other pin controls the other 2 red leds, of course as before, for the leds to work in 2 separated groups is needed to cut the trace that connects the bases of the 2 transistors, then solder the wires from the PIC microcontroller to the transistors

For this mod is not posible to use the trick explained before that takes advantage of the fact that there is a trace "available" along the ribbon cable, there is only 1 trace "available" in the ribbon cable and for this mod are needed 2, even if you mount the PIC sticked to the switches board then 2 wires needs to go back to the PS3 motherboard for the sensors... so one way or another are needed 2 wires in between the PS3 mainboard and the switches board

*When temperature is low... blue leds 100% intensity... red leds 0%
*When temperature is high... blue leds 0% intensity... red leds 100%
