    Also, I notice you seem to be using a polyester capacitor for C9 0.47uF. Is that true? Polyester capacitors are fine for audio applications but have poor high frequency response and aren't much good for supply decoupling. If you can't find an X7R ceramic you'd be better off using a tantalum, or even another of those 0.1uF ceramic capacitors for C9 rather than a polyester.

    I mean, it will still work with a polyester. It's just less than ideal.

    Done!

    Yes, when C23 is grounded the output is low, if at +5V the output is high.

    I know, the transistor there is suppose to work as an NOT GATE (inverter), when the input as his base is high the output(collector) is low and so on, but is not working that way. Changing the C23 configuration the output of IC7 is high but mean nothing to T2 as his first state, S1 works fine.

    Maybe R1 is too low.

    The guy sold me as a high voltage ceramic, but i told him that it looks like those old 90's Philips Polyester caps, the same guy/store sold me that multi layer ceramic caps that you see on the board. The guy must know something or is selling wrong stuff (??)

    Later i will change, at my prototype board, that to a 220nF multi layer ceramic, is the higher value that i have at home.

    Talking about "supply decoupling" some years ago i've found it talk about the correct values for supply decoupling.

    That article about supply decoupling is very good.

    R1 value of 1.5K seems right to me.

    Can you please toggle 555 so that pin 3 is high and measure the voltages on IC7 pin 3, on each end of R13, and on IC4 pin 9. Then toggle pin 3 low and repeat. Post your eight measurements for us to see.

    Other things to try in the meantime:
    • Check you don't have a short circuit around IC5 pins 12 & 13
    • Check for bad joints around R21, T2, R13 and pins 9-11 on IC4 and IC5.
    • Replace T2, making sure it's actually a BC547 (or BC548), not something else.
    • Replace R21 by a 10K resistor, and mount an additional 2K2-4K7 resistor between T2 base and emitter.
    • Try replacing R13 with a 4K7, 5K6 or 6K8 to see if it makes a difference (it shouldn't).


    You say the circuit works when you're not using T2. I'm curious - what exactly do you do to test the circuit without T2? Do you desolder T2 and connect a flylead between IC7 pin 3 and IC4 pin 9? If not, how do you do it?

    That is not necessary anymore, the problem is fixed, i don't know exactly why it doesn't work with this circuit in specific, my headphone amp uses the same switch with the transistor not gate to trigger a relay, this device doesn't turn it self on when i connect the AC cord to the wall and the 555 is set to start high.

    Anyway, the problem was that the 555 would start low not matter the configuration set, there was no short or anything, so i removed that capacitor and put it at SW1 to give the IC7 an initial trigger, that works, the interface start as PH mode instead of JDM.





    Here is the updated schematic:

    I did with a jumper and removing T2/R13, since IC7 was configured to start low.

    Man, this is a very dangerous interface, i've take notion of it today.

    I've took this interface to a friend that does cellphone repair for a well know company, since i don't have access to empty cards i need to know if the interface writes, i know it reads fine. He connects the interface to his laptop, fire up some strange apps (very, very strange i might say), ask his friend for his GSM SIM CARD, put that to an adapter and slide that in to my interface.

    After about two hours (or more i didn't count, we wore playing PS3), his was able to clone his friend GSM card in to a special one, using my interface, that can hold up to 3 different GSM SIM cards in one single chip. We wore able to recover a lot of sim card info like, personal information, phone numbers, time and date information, last numbers called, phone book, company information, functions & services activated/deactivated.... lots and lots of information, it took less than a minute to dump all that in to a text file.

    He also did some other things with it that i don't dare to talk about it here. I know that this is just an interface with "hacks" applied that does nothing by it self without a specific program, but damn, i was amazed.

    This friend told me that this can be very handy for serious work like repair and something else related, but also can be miss used.

    Because of that, i take no responsibility for what ever mess you can get in to by using it or miss using it.

    Be responsible.

    can i ask , how much does it cost to build roughly , including an etching kit etc..

    thanks

    Yes, i don't know how much it could cost at each one country, the most expensive part is the smart card adapter for about 4.22, on my country it cost about $16.00. Etching and other stuff is very hard to say, maybe under $60.00.

    You might be able to do a little production run of boards and make a few $$$ on the side People can then drill and assemble them.

    Yes i know how this goes.

    Thanks but, the schematic is public now, i'm sure that some company or other person will deal with it and sell it, i really don't care, maybe some one would make a smd version of it.

    After the experience at my friends home, i got my old SIM card and make a run on it:



    Is a disabled chip, i did some tests here with success (read/write), this are some parts of a big text file:

    Is your SIM card 3G? What software is being used? PM if necessary.

    Can you supply an updated board design too - would love to build this as my next project.

    Thank you for sharing your work.

    No, my SIM card is not 3G, for the software google for "SimScan v2.01".

    Thanks for that

    woops didnt notice the multiple pages in your pdf

    One question, is there a purpose for the 3.6864MHz xtal? Can it be replaced with one of a different frequency without issue?

    Thanks again.

    Yes, most crystals between 1-10MHz will work provided it's not too fast for your card and your system is properly configured to support custom baud rates.

    That VP30 (aka Art That Hurts all-burner) design you posted is ambitious and cunning, with a reasonably nice PCB. But it has a couple of dangerous features, particularly driving TxD directly into the HC00 input!

    It probably works but cuts too many corners for my liking.

    For what i've learned from my own, the VP30 looks like a SC killer.
