Data acquisition

[maintain]

Hi guys,

I would like help in obtaining data (voltage and current requirements) from a device (e.g. mobile phone, laptop etc) without switching it on, (possibly applying just a signal voltage not plugging it into a source) and then send this data to a microcontroller of some sort, for analysis or decision making.


This is part of an automatic variable power supply I'm trying to design.


Schematics would appreciated where possible.

Thanx guys!

the best way would be to use a stream of photons, use them to read the compliance label. There is a wide difference in voltage and current requirements for mobiles and laptops, mobiles 4 to 10V(100mA) laptops 12-20V (2Amp). If you aply 20V to a mobile, you can use the photon beams again to watch the smoke.
