    MOLEX (PC power), eject switch and PMT probe all in one!

    Hi there, just for the noobs I thought I would make a clear wiring diagram for flashing your drives using a PC power supply along with home made eject switch and a PMT probe solution.

    Should cost you about 3 or less in the UK for switches, regulator and veroboard. Try your local Maplin.

    Source of PMT info...

    Using probe on lite-On......

    Press Phatkey
    Hit OK
    Hold probe button down
    Probe MPX01 on drive shown here
    Release probe button
    Wait for Jungle flasher to show "0x52"
    Remove probe
    Wait for jungle flasher to show "extraction complete" Don't hit OK yet!
    Hold probe button down
    Count to 5, no really count to 5!
    Release probe button
    Now hit OK

    Mods can you check over and approve, I will amend if need be.

    Enjoy!

    Good to see someone doing somthing creative for once. Can be half the fun!


    Removing 3.3v from a phat will be enough to cycle the drive when flashing, so use PMT button without probing to cycle.

    Removing 3.3v from a slim does not seem to have the same effect and so you will need to remove both 12v and 3.3v at the same time(note, I can unplug and plug molex back in quick enough so never bothered with it.

    You obviously cannot mix the 12v supply with the 3.3v or 5v on a SPDT switch.
    Its not advisable to fit a switch to remove ground as there is still a voltage drop between 12v and 5v lines.

    So you have a few options......

    1 Use a DPDT switch.

    2 Use two SPDT switch right next to each other and make sure you use both at the same time.

    3 Change the 3.3v regulator to one which will run off the 12v source and then you only have to disconect the 12v source using a SPDT

    4 Although daft you could have a 12v relay switching the 5v line so when you remove power to 12v the relay disconnects the 5v but thats the long way round asuming you dont have the bits needed for above options but do have a relay.

    If you dont have the switches required and your regulator can handle 12v move the input pin to 12v and go for option 3

    Let me know what you have and which option and ill knock you one up....

    i think i will go with option 2 as i allready have two spdt switches. could you knock up a diagram of it please

    and again thanks for your time and help

    ps. does it matter that i have not used a regulator because i allready have a 3.3v line from my power supply. also to power off the drive is it the 12v & 3.3v or is it the 12v & 5v or will either do thanks again

    If you already have 3,3v line you don't need regulator. I think alexhore made this tutorial to demonstrate how to get power from molex only And in my opinion, 12v and 3,3v should be enough to power off drive (but if you manage to switch off all 12v, 5v and 3,3v you can be pretty sure, that drive is definitely off )

    The 3.3v comes from the regulator and the regulator is powered by the 5v and so all you need to do is remove 12v and 5v at the same time and there is then no power at all to the drive.

    just looked for my old xbox360 and cant find it any where could you please tell me the part number of a few different 3.3v regulators
    so i can order one as i am getting confussed on which to buy.

    ps could you check the maplin electronics website and let me know if they do a regulator which will do the job as it is my local store but the staff are useless

    thanks
