I was cleaning out the upstairs and found a usb device left here by a past tenant. I have no use for it in it's current state so decided to harvest the components from it. It's a microsoft sidewinder strategic commander:
I'm happy that so far I've recovered:
-An intact USB cable
-12 momentary push switches (score!)
-6 amber 3mm LEDs and 1 red 3mm LED
-1 resonator (not sure the frequency)
-a variety of connectors I should be able to reuse
What I was REALLY hoping I would find is a couple of 3v6 zener diodes to use with AVR to USB project for the D+ and D- lines.
So here's the question. On the main board coming off of the D+ and D- usb lines there are a couple of smd parts labeled FB1 and FB2. Any idea what these are? I have tried some multimeter tests and can't figure it out.
