My phone has Bluetooth, WiFi, GPS, MP3, USB, camera, composite video output...but it doesn't have a multimeter.
The damn thing is chock full of DSP, A-to-D and D-to-A converters, shirley it could have a simple multimeter, for those times when, you know, you just have to measure a voltage.

Turn your PDA into a multimeter http://www.engadget...s-into-multimeters/
...and if your cell phone has a CF or PCMCIA slot, then I imagine it will work on that. [DrCurry, May 06 2008]

       Damn. Thought this would be an artistic hodgepodge arrangement of dangling electrodes and readout displays :(

No, that would be a "Multimeter mobile".

       Yes, indeed. By the lack of power invested in me, I give you the rights to both. +

       Oooh, there is a big reading from the flux capacitor in your De Lorean.

       Most phones have a battery charge indicator, albeit with fairly low resolution. Should be a simple matter of finding the right connections and bringing them external, adding a switch to go between functions.

       dang, I already [+]'d it. This would be a hefty yes-weight on the scale that determines if I ever get a cell.

       [+] But I don't think it'd be a minor modification. A normal multimeter handles voltages over at least 4 orders of magnitude, and also measures current and resistance. "Multi" right?.   

       I'd pay extra for such a souped up 'phone, though. They'd probably be visibly different from cellphones (bulkier, at least), so they'd be geek fashion accessories: anyone who carried one would be declaring him/herself the sort of person who feels the need to whip out a multimeter at a moment's notice and start debugging the toaster.   

       A subset of "multimeter" that probably *would* only require a little rejigging, and would be really handy is a continuity tester.

You've almost certainly already got one of these - all you have to do is make a cut in the headphone cable.

       Seeing that most phones have bluetooth built in, a really handy accessory would be a bluetooth multimeter adapter.

       I'm *really* sick of losing and breaking multimeters and buying cheap crap ones from Maplin.
