* HP deskjet motor, in deskjet:  
 free running at 12V, 250-300mA, runs well, fast!!
(stalls @ 1A)


* small axis of the 2-axis thing,
 runs well @ 20V, ?A
 runs well @ 15V, 1A

* large axis of the 2-axis thing:
19 V, 0.4 A


* plastic lead screw:
doesn't quite move @ 12V, 1 A,
 but runs well off the 12V, 3A power supply


* "PELIGRO" plotter: runs well @ 12V, 1A
* (another like it in ESG...)

2 = GND

1 = signal

10 = index (pulse 1/revolution, only exists on some encoders)



HP deskjet motor

free running @ 12 V: 50 mA?
                stall @ 1A
sounds good


plotter motor w/ ground-"flat" on shaft
free running @ 12V: 200mA (sort of slow, doesn't sound so great)
             @ 24V: 250mA, faster...
stalling quickly brings it to 1 A (probably stalls much higher)



one rotary thing w/ green pot:
@ 12V: draws 1 A, drops to 9 V in (so needs > 1 A),
 runs smoothly.


other rotary thing: stuck


scary REC motors: 12V,1A, barely works
 (much higher current!)
