I purchased the kit several years back, if it is still the same, it's
based on the 555. I used it for a barn door after changing a resistor
value. The 555 was stable enough for my low power photography and would
be for visual in your application (YMMV!). "Speed control ranges from 1
pulse per second to beyond 1500 pulses per second" is quite a range and
you may find it hard to get a stable speed over a time and temperature
range without some circuit modifications, but would make a great
experiment for visual use. That's my two cents ;-).

Hi my friends!,
 
Im starting to design my 12.5 split-ring mount and I was thinking of
putting a 
differant type motor on this one,,on my 8 & 10-inchers I used
dc-motors,but
I like to experiment and do things differant, so I thought I might try a
stepper
drive this time around,,but Im LOUSY at Electronics,,
[BTW,, Heres a funny story about that];
I tried to build the 555 stepper-circuit ain the early-80's after i saw
the wright-up
in S&T, so I built the circuit [it was Scary-looking!, I had wires going
everywhere!,
it was a mess!, and I proceeded  to plug-er in to the motor!,,BOY did I
do something wrong!!,
all the motor did, was vibrate!, and jumped up-and-down on the
Table!!,LOL,,LOL,,
it was hilarious!!,,,so that was my last attempt!.LOL,,LOL,,,,
 
Anyway,,
I found this circuit at "harbach & radman", on their website, and was
wondering what You guys thought,, would that circuit do for a drive??
Here's the address;

Product_Code=TM93KIT2421%2FA&Category_Code=STEPMTRCTL

any tips from you guys[or gals, sorry "astro-lady from Australia", your
a nice Lady!].
TNX again!!
