11015 Mon, 28 Feb 2000 12:01:50 -0500 [alt-beam] CD-Rom Motor info beam@sgiblab.sgi.com Marcus Cole Hello all,

I'm new to beam, and i have a basic understanding of electronics. I have
been offered 4 old cd-rom drive(minus the pcb) and i was wondering if the
motors in them are any good for BEAM bots?

...I think so. I regularly "pull" off wire from the coils to make longer
leads. But the re-winding portion is a nasty bit'o'business. Not fun to
spool it up and try to re-glue the windings. What you have in mind?

Same time delay as any other SE - depends on the voltage trigger, cap size,
and sunlight. But in regards to discharging, they're just as quick as a
motor. After all, they're what - 13 ohms?

...to drive a bicore and a SE? I'd probably want to stick with the 5V
cells, being the 3733 & 3766, as the '240s all run better on higher voltages.

Dave

Oh, I'll keep that in mind. I found it in TorBase and took it for granted
that it was allright. I'll be sure to go for 337's the next time.

Thanks and cheers,
