    Default Let's make our own Turbo sim, any ideas?

    So all those proxy cards cost a lot of money, but why not to make your own. Schematics are rather easy and the most expensive part of those cards is microcontroller ( MCU).

    I made some research on the internet and found out that Turbo sim uses atmega128 MCU, but does anyone has any idea what MCU uses Stealthsim, Next sim and so on. I think that MCU's on those cards are the same. And it is very likely that required MCU's cost few bucks in China. So all you need is to develop a PCB and place MCU on it.
    Even if it would be only an experiment version, but why not to try out?

    Another idea is that those cards might be manufactured by one factory, so if we know the MCU specification it would be possible to track manufacture and order directly from it.

    Another thought is that Magic Sim and all of those mentioned above use the same MCU.

    And of course the hardest part is the software, but we have Turbo sim software, right?

    Let's throw some ideas and make things cheaper=)

    I honestly think you're going to spend much more money making your own Turbo SIM than actually buying one.

    It takes a few (and very expensive) equipments to manufacture a circuit board like that. And I believe you can't simply design the board and just send it to a circuit board manufacturer to make just one or maybe 10 boards for you. As far as I'm concerned, you have to order them by the hundreds (someone correct me if I'm wrong).

    Not to mention the hardware (and software) expertise that it takes.

    I don't know your level of knowledge in the area, but I'm an Electrical Engineer and I can't pretty much tell you that this idea wouldn't be much applicable.

    Best regards.

    fully agree with the previous post - that's the problem. To get it for cheap, after you designed the board, you'll first have to order a very large (more in the 1000s than in the 100s I'd say) quantity. Then pray for no software unlock or Apple patch until you sold your full batch. Not really a good business

    and yeah, using an ATMega128 is wayyyyyy overkill for what AppleSaft is doing
