too much power to the tray?
too much power to the tray? –
OKay the thing is, I had modded my ps2 for the tray switch mod, basically I had a little switch that opened and closed the tray so I could swap discs, with a 3 volt battery pack powering it which I kept in the expansion bay of my ps2 (V3).
I was tempted though and decided to buy a network adapter and fit a hd into my ps2, which meant I had no space for the 3 volt battery pack in the expansion bay, so I hooked my switch straight up to the 5V points on the USB on the PS2's mobo (I figured since the switch would only be taking power for a very short length of time when inserting discs it wouldn't render the USB ports unusable....but anyways).
Now my problem is I'm wondering if 5 volts is too much for the tray motor, as it opens pretty damn quickly (if the discs still spinning, it'll shoot out of the tray when I open it lol). Since I installed this my ps2 seems to be having a bit of difficulty reading discs in the browser too, for instance I loaded to browser, put in a disc using the switch and it came up reading disc, then nothing, it didn't say disc read error but at the same time it didn't come up with a picture of a disc in the browser menu, just my memory card.
Not sure if I have a real problem here, but anyone's opinion would be appreciated
Would it be possible to lower the voltage to the motor via this 5V point (I'm not very good with electronics tbh and the 5V USB point was about as daring as I wanted to be in soldering to the mobo).

you could maybe try a 56 ohm resistor but i would hook it up to a multimeter to check..if you can't find a resistor thats 56 get 1 thats close
um okay how did you do that lol? I'm pretty sketchy with electronics as I've only done it in high school for a few years.
I should hopefully have solved my problem anyway, I went to my local maplin (electronics shop) and told them what I wanted to do, they gave me a 470ohm(I think, ca'nt exactly remember) variable resistor which I should be able to hook up and adjust to change the speed of the voltage, gonna try this tomorrow hopefully as I'm quite drunk atm lol.
oh lol thanks
the motor seems to have slowed down by itself anyway now...don't think it's a good sign though lol, may be burnin out
i did this with my v4. i got the 3 way switch and ran a 9v battery to a regulator to drop it to 5v. mine shoots out quickly but i have no problems otherwise. i put it all in a small project box from radio shack. the small box holds a 9v and some wires pretty nicely and doesnt look horrible. im considering adding another 'button' cause im scared the switch will get knocked on by accident and not be noticed. i figure ill just throw it inline before the switch. put the switch to open and press the button - it opens. flip the switch to close and push the button -- closed. either that or i need to look harder for a momentary switch cause noone had one when i went looking.
