Subject: [alt-beam] Yo, Team!
A couple-three questions:
(a) can you drive a "typical" BEAM motor from the output of a "garden
variety" 741?
(a)(1) presuming you had an "unlimited" power source, using a couple of
741's to drive a "standard" h-bridge would likely end in fried parts under
normal operating conditions (whatever the heck they are) of a BEAM device,
right?
(b) would it be better to use a comparator, something like a 339 instead
(and you get four in one chip..)? In this case I'm supposing direct drive
of the motor with the comparators and not even considering an h-bridge.
(c) I'm not ignoring the '14s and other digital stuff but, sheesh, isn't
there any decent more-or-less linear analog stuff that isn't too
gosh-awful
Anybody have any thoughts?
Zoz
p.s. Happy Bloody New Year, Y'all!
