Don't forget Terry Fritz's Radio Shack strobe light modification.  This is
can be built for about $40.00 total and works
extremely well even in very bright light.

Hello All:
 
I never noticed the fact that these motors were all hysteresis synchro
motors
and not true salient pole motors.
 
I have, with Terry's help, found the cheap cure for this problem.
 
Terry has a very simple "strobe" circuit using a LED on one of his
streamers. 
This uses a 12 VDC, 1/2 Amp xmfr with rectifier diode and peak current
limiting
resistor to drive a LED which functions as the strobe light.
 
The circuit is very simple and mounts out of the way in a small box.  I used
a
Digi-Key part no. 67-1604-ND ($3.00) high brightness WHITE LED as the strobe
and mounted this on a flat cut onto the end of a piece of delrin plastic.
The
strobe is mounted on the delrin stalk approx 1 1/2 inches away from the
stationary electrodes with the LED facting the stationary electrodes.  I
applied a small flourescent adhesive dot next to one of the rotor
electrodes.
 
You flip the RSG motor switch on/off 2-3 times and you can get a nice sync
for
the electrodes.  If you're lucky you hit it the first time, but usually a
few
flips of the switch will get it very close for you.
 
It's worth the effort because these synchro motors give a nice increase in
spark output and the streamer, as viewed with 4 sec time exposure, is much
"bushier" and thicker than a standard spark gap --- indicating more current
in
the streamer.
 
Hopefully Terry will notice this email and post the correct streamer for the
list.
