help me plz this is my first project (:

推荐答案

无需道歉-尽管我非常感谢为此付出的努力. :)

咧嘴笑-是的，随着时间的流逝，书面交流无疑是我们所有人都会变得更好的一项任务.实践使完美(或更好，或类似的东西.)

好的，太好了！ -现在您的意图非常清晰.我以为您可能想要做这样的事情，尽管不想猜测并做出疯狂的假设.

我认为这个项目是一个真正的"doosie"，即使是经验丰富的硬件黑客也将发现它非常具有挑战性..

我希望我以前的问题不会给人以为我一定有解决任何问题的印象..

您也许可以找到一些讨论GSM协议栈规范的文档(我认为是GSM协议栈的规范)，这是解码发送数据的电路的低级部分.您可能能够将导线焊接到正确的引脚上，并使用一些逻辑门作为解码器来查找特定的输入-也许借助小型微控制器，您可以拦截那些文本消息的内容，以从中提取文本命令他们?我真的不知道-我在大学期间学习了数字系统，机器人技术等，那时的手机非常少用(而且容量巨大)-我们当然从来没有过.

还有一点需要考虑的是，许多警报系统都具有蜂窝网络连接性(例如较新的可乐机)，您可以配置一些警报系统以在检测到活动时发送文本消息. _也许_这些模块无处不在，您可以找到一个硬件DIYers论坛，该论坛使用此类模块来报告/控制警报的活动.

当时我在那儿，从离散零件到集成解决方案的更改不太完整，您仍然可以在许多项目(最大65,536字节！)中找到EPROM(带有擦除窗口)！-我什至从许多地方拆焊了在我们的实验室课程中使用的防辐射板.


我之所以提到所有这些原因，是因为今天(大约20年来)手机大部分是集成系统-许多不同的松散相关功能都是在单个芯片中完成的-您甚至都无法使用大头针或电线他们消耗和创建的数据.可能最容易完成访问数据的操作是:(a)用手指按下按钮以输入数据的机器人，或者用摄像机和手指导航并访问数据的机器人.手机内部的电路工作在很高的频率下(很多Mhz甚至Ghz)-要找到数字采样CRO来用很少的钱检查这些电路并不是一件容易的事.

同样，对于GPS装置，我仍然希望可以重新利用它，但是要找到数据表可能非常非常困难.但是，要寻找诺基亚3310和5510手机屏幕的替代用途，需要大量的DIY.也许也有一个DIY gps黑客社区?


老实说，我可能会考虑尝试使用现成的组件来完成该项目，然后将这些组件塑造成一个完整的系统.

您可以花大约

No need for an apology - though I do appreciate the effort to make it. :)

Grins - yes, written communication is certainly a task we all get better with over time. Practise makes perfect (or better, or something like that..)

Okay, fantastic! - now your intentions are crystal-clear. I thought it was possible that you may have wanted to do something like that, though didn''t want to guess and make wild assumptions.

I think that this project is a real ''doosie'' and one that even a seasoned hardware-hacker would find very challenging..

I hope my questions earlier didn''t give the impression that I necessarily had a solution for any of them..

You might be able to find some documents that discuss the specs of the GSM stack (I think its called that) which is the low-level part of the circuitry that decodes the data sent. You may be able to solder wires to the correct pins and use some logic gates as a decoder to look for specific inputs - perhaps with the aid of a small micro-controller, you could intercept the contents of those text messages to extract textual commands from them? I really don''t know - I studied digital systems, robotics, etc at college, mobile phones were quite rare (and HUGE) back then - we certainly never had them.

Something else to consider is that many alarm systems have cellular-network connectivity (like newer Coke machines), you can configure some to send a text message if activity is detected. _Perhaps_ these modules are ubiquitous enough that you could find a forum of hardware DIYers that have used such a module to report activity from/control an alarm.

I was there around the time that the change from discrete parts to integrated solutions was less complete, and you could still find an EPROM (complete with erase window) inside many items (max 65,536 bytes!) - I even de-soldered many parts from ircuit boards to use in our lab classes.


The reason I mention all of this, is that today (and for about 20 years) mobile phones have been mostly integrated systems - many different loosely related functions are done in single chips - you wont even get access to a pin or a wire for much of the data they consume and create. Accessing the data may quite possibly be most easily done with (a) a robot with a finger to press buttons to enter it, or a robot with a video camera and a finger to navigate through and access the data. The circuits inside the phones operate at quite high frequencies (Many Mhz, or even Ghz) - it''s not terribly easy to find a digital sampling CRO to examine these circuits with, for little money.

Likewise, with the GPS unit - that is something I would still be moderately hopefull could be re-purposed, but finding a data sheet may be very, very tough. BUT there is a big DIY following for finding alternate uses for the screens from Nokia 3310 and 5510 phones. Perhaps there is a DIY gps hacking community too?


To be honest, I would probably consider trying to do the project with off-the-shelf components that I then fashioned into a complete system.

You can buy GPS tracking units for about

35来购买GPS跟踪装置-也许价格便宜，值得与您一起玩.但是，尽管接收器的价格相当便宜，但我不知道出售它们的公司所使用的方法来将设备的位置报告给您，即用户.它们看起来大约是3G互联网棒的大小，所以也许它们以这种方式发送数据-这就是为什么您必须支付月租费的原因.
但是，如果您可以自己读取位置数据，则不会阻止您使用无线电传输从其中读取的数据.也许一对廉价的CB无线电(5公里范围，〜

35 - perhaps this is cheap enough to be worth playing with for you. BUT while the receiver unit is quite cheap, I''m not aware of the method that the companies selling them use to report the devices location back to you, the user is. They seem about the size of a 3G internet stick, so perhaps they send the data back that way - which is why you have to pay a monthly fee.

But, if you could read the positional data from it yourself, there''s nothing stopping you from using a radio to transmit the data you read from it. Perhaps a pair of cheap CB radios (5km range, ~

30/对)就足够了-您" [d仍然必须自己调制数据-a

30/pair) would be sufficient for that - you''[d still have to modulate the data yourself though - a
