Well, i finally got it to work, it seems a bit strange but it just started
working after i did some reconfiguring, turning radius is pretty big but what
can you expect from only two motors. Thanks for the insight!

you need two photodiodes connected across the
master bicore timing resistor.

11612 Sun, 12 Mar 2000 09:59:16 +1300 [alt-beam] The latest websites (and Wilf's circuits) beam@corp.sgi.com Justin I've been out of the loop for a while, and I'm having difficulty
finding the bounty of the last few months, due to my heavy reliance on
sites like Fang's and Beam Online, which are currently in a slow period
regarding updates. Are there other sites that now fill the same
function?
I'm particularly looking to see what kind of circuits have been
developed over the last few months(/year...). I know Wilf's done some
neat stuff, and I assume
that other nifty, odd, esoteric, specialised, complex, simple, and
interesting circuits have also appeared. Is there a site or group of
sites that collect this stuff? (If it doesn't exist, a giant circuit
site that's got all the stuff in addition to the ubiquitous 1381 SE,
FLED SE, photopopper, and other stuff, would be a great idea, hint hint
:-) I've got a couple of circuits that could help get it started... :)



11613 Sat, 11 Mar 2000 16:14:09 EST [alt-beam] Re: Pager Motor beam@sgiblab.sgi.com Meabadboy@aol.com is this similar to the pinion puller used in 24 scale slot cars?

it is basically a c shaped piece of metal with a threaded center pin that is
tapered down at the end to the inner diameter of the shaft that the pinion of
the motor is on ~ when you slip the c clamp onto the shaft behind the pinion
gear you tuen the center pin twards the gear and it slips the pinion gear off
the shaft

that is for a walker?

cars, with small gears, would they work well?
