Please log in for more thread options Hi YD, the development platform is a PC/laptop. But this project can be ported to a handheld Pocket PC. The reason, why it can't be done to a size of cigarette box pack is simple: the demand for high number crunching computing performance. That's the reason, why this project becames very simple. All the detector is done by pure software programming. Aziz | |||||||||||||

In other words, unless the "high number crunching" is adding soemthing to make this better than the average metal detector, it's only purpose is to compensate for the lack of circuitry. A software modem needs a lot of number crunching, but that does not make it better than a hardware modem. Just cheaper, though of course I can use my hardware modem with any computer hardware, including something from 30 years ago. Michael | |||||||||||||
