== PS3 2000 series Power Eject boards, enabling contour leds talk == | |||
This is a temporal section to discuss the simplest/easyer/safest/better way to make this mod, and the posible variations | |||
Is probable that exist a prototype that uses pin1 (or is connected to an intermediary device), is needed to be 100% sure the pin goes nowhere (is posible the trace goes to an internal layer of the motherboard not visible in the surface and emerge again in a syscon pin) | |||
If the pin1 line is really disabled, we can use it to carry other signals from the motherboard, like a temperature sensor, the PWM pulse of the fan, etc... add a small microcontroller in the power eject board with code to controll leds based in temperature (a PIC is a good candidate and there are 5v in the board) or even some kind of small display, etc... | |||
== Pin 1 identification == | == Pin 1 identification == | ||
All components whose pins needs to be marked in electronic equipment (because the component has several pins, like any chip/IC or connectors) always has a mark in pin 1... sometimes this mark is not visible because is "printed" under the component itself (so only visible before soldering the component to the board)... this seems to be the case in some of the connectors in PS3 power/eject boards, so the identification of pin 1 can be confusing | All components whose pins needs to be marked in electronic equipment (because the component has several pins, like any chip/IC or connectors) always has a mark in pin 1... sometimes this mark is not visible because is "printed" under the component itself (so only visible before soldering the component to the board)... this seems to be the case in some of the connectors in PS3 power/eject boards, so the identification of pin 1 can be confusing | ||
