The 40-50 ohms seems to be the headset's (microphone's and speakers') internal resistance. However, I now have a circuit (now just made of resistors) that has almost identical resistances as the headset, but it still won't shut down the internal microphone. Could there be some other magic that the device is using to probe for the microphone? Replying to myself here.

Re: I wish you could see what was running before Nokia dies
Hi again :) Latest osso-statusbar-cpu has some code in it to average cpu usage and notify you (it won't log, just play a sound and display a notification) if something's hogging the cpu (aka draining the battery) Here: http://www.maemo-hackers.org/browser/osso-statusbar-cpu/trunk It's not included in a release (yet) though.

Hildon Input Method is released
Salaam, (Sorry to cross posting) Today we are releasing the Hildon Input Method. The part we are opening are the input method framework, common UI part and plugin system plus a plugin example. They are released in LGPL version 2.1 (for the framework and the common UI part) and BSD (for the plugin example). Check our (new) homepage: http://live.gnome.org/Hildon/HildonInputMethod Enjoy. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

I took some lessons from Wikipedia and came up with a circuit diagram that could give similar resistances than the headset: --- R1 - + || - V1 -- R2 |- M |+ --- - Where R1 is 1.8 kOhm resistor, R2 is 2.7 kOhm resistor, V1 is a diode and M is the plugged in microphone. The diagram may be wrong way around, but the idea is that to one way the circuit has ~1.8 kOhm resistance and to another ~1.1 kOhms. However, at least my diode (1N4004) seems to have too high set-on voltage for my multimeter's ohmmeter while the headset can be measured OK, so I can't verify the results with it. Also I noticed that there seems to be two inductors, one semiconductor and a small resistor (50 Ohm) in the headset and there's probably a bigger resistor in the push-button. There also was some component between the microphone's pins which I assume is a conductor for the mic (I lost the component). Also I can't get any readings of the semiconductor (it's marked V01, which would say it is one) and I have no idea how to measure specs of the inductors. However, I'd guess that the circuit has some kind of transformer for the microphone, which could also lower the set-on voltage of the diode. So to put the above together, I have mostly faint guesses how the system may work and any advice from people with more knowledge in electronics would be very appreciated. PS.

Re: N800 audio connector jack
Should try 1n4148 as the diode, although I can't offer much help/ideas other than that. Very limited electronics knowledge. You can salvage 1n4148 or alikes from any radio or scrap pcb lying around. Look for the tiny orange-ish[1] diodes. [1] http://www.eleinmec.com/figures/029_02.gif On 9/8/07, Jami Pekkanen [EMAIL PROTECTED] wrote: Jami Pekkanen wrote: Continuing my monolog.
