All the blue t911 I've seen have a built-in regulator and will happily work up to 18v ac or dc so there shouldn't be a problem with your 12 volter .....cric2k said:Hi,
ive just bought my first t911 and i'm about to try unlocking my first card.
unfortunately I can't find a 9v power supply about, only a 12v one.
Will this work or cause any damage to the cards?
TWOBEERCANS said:if your t911 fails when using a 9v power supply it is a question of insufficient current being supplied. on a variable regulated power supply it will make no difference to the t911 what voltage you use. because all that is actually required is 5.6volts.
nozzer said:Not quite sure about that !
Whilst most of the circuitry runs via the 5v regulator the actual glitch pulse is derived directly from the supplied power supply without going through the regulator.
TWOBEERCANS said:that make's perfect sense.
since the actual gates operate at 2/3 vcc (threshold) and we can't manipulate this then the vcc on the card must be manipulated in order to create a grey area as far as the 2/3rds vcc is concerned. so we end up with a gate that based on very tight timing wouldn't know wether it was open or closed.
but the suspision would be that a variance much lower than a few volts could be employed. infact i had estimated that .6 volts would be ample, the need for a rock solid power supply is of course apparent.
from what i have seen it is crappy power supplies that make 9-12volts a prerequisite of the glitching process.
i also thought that nagra cards could work at 3.3volts and had a tolerance for 5volts. < this of course is an assumption. bet i sound stupid now lol..
