following my post http://arduino.cc/forum/index.php/topic,73169.0.html
instead of trying to find the right connectors or solder stuff on the board, i was thinking maybe i could go mac gyver style
i already know the application protocol used between host and device.
i know the device uses either usb or serial communication (on second thought, i'd say usb, but i am not sure)
i know the communication is half duplex (meaning it's a question->answer approach so to speak, not both ends are not talking to each other at the same time)
it looks like there are 4 wires here. my guess is
* black is ground
* red is power
* green and white may be signal+ and signal- ???
==> if this hypothesis is correct, then i care only about green and white wires.
maybe if i cant identify the connectors and am too affraid to solder stuff on the main board, i could try to strip a very small part of both green and white wires and attach a probe there likehttp://radiospares-fr.rs-online.com/web/p/grippe-fils/1030254/
and from there connect those two probes to either bus pirate or an arduino board and continue tinkering/exploring
* does such an approach make sense ? or is it plain stupid ?
* how to strip such tiny wires without damaging the cable?
- does burning the plastic cover on about 1mm of wire would work? or is leaving burnt plastic on the wire likely to introduce noise and/or connection issues ? is heat likely to cut the metal too ? (i was thinking of using a soldering iron, but what temperature should i use then? alternatively i was thinking of such anti-wind lighter flame such as
(but it probably is a too big flame to make a decent job (would probably burn the rest too, no?)
- should i try to strip them with a surgeon scalpel ? if so, how likely is it to cut the wire too ? (not to mention hurting myself :p) ? is there a particular technique to do it right ?
- any other idea to partially expose the core metal of the tiny wires without damaging the overall cable ?
thanks for the ideas
