Thar be ground! … now what?
I’ve taken apart my RAZR rather masterfully. In front of me is the tiny speaker (could I somehow hook it up to a mini-jack and use it with my cheap 64 meg flash MP3 player?) and the board that contains the vibrating mechanism.
It says 6 5y6 on it, but the tiny motor otherwise has no markings. It’s pretty solidly adhered into the board – at some point I’ll need to break out the solder gun and see if I can’t melt it off – hopefully it isn’t glued in.
I can find NO real information about this motor. This is as close as a get, from some schematics I rustled up:
AHA! you say. Triumph! Except, I have no idea what I’m looking at, here, ‘cept the ground cymbols. is the 21 a reference to something on another page, or is it volts or ohms or something? *boggle*
Well gee, why don’t we break out the volt-ohm meter I picked up today for $3.18 cents!
Hmmm, I see two likely leads, so let’s try resistance first. following instructions, I set it on 200 ohms and put the testers down. Uhm… somewhere between 23 and 26, constantly cycling?
It’s at this point that I admit to myself that I didn’t pay any attention in electronics class, and I need someone else to walk me through this, because I’m not that specific kind of geek.
Damn.
EDIT:
I found that, too. Somewhere else. Woo!

*peers at it, nods sagely* Oh yes, I see where I was mistaken.
o_O
Unless I’m mistaken.. Ohms is a measurement of resistance/impedence. Try switching your multimeter to 20VDC and then take a measurement. ;-)
*L* I do know the difference between volts, ohms and amps.
But that doesn’t mean I know how to read a multimeter. Setting it to 20 DCV (as it says on the meter), what’s the reading come out to in volts? Hm.
I’ll take apart the old phone I have, and see what that wants.
If you want more old cell phones to take apart and play with, let me know. I have about a half-dozen NIB Motorola E60s complete with bilingual manual and AC chargers.
