Next leg:
What goes in the lower leg section in this kit? Mike? Dave?
Make sure you glue this greeblie to the lower leg segment only, so the upper leg can hinge freely:
Glue the greeblie into the upper hollow as shown:
Ill have a dig for that info Jason, cant recall the ID as i didnt write it down.
Its a gateway kit i recall, so shouldnt hard to find for you, but ill check if the other guys dont know.
BTW, lower leg channel should be 6.4mm in height, thats why it looks a bit hefty with the claw fitted.

Where is the you tube link Jason?
Looks pretty cool this contraption!
Just a thought , of you used longer horns , would you get not the same travel?
Without doing the pulley system?

Post #181 - it got lost in Lee's copying the photos in his reply:

Can you draw what you mean? Longer arms on the servo means you might run out of room in the head...

Actually Jason that works awesome!
Is the weight of the brass bringing it down?
I will get back to you on the longer thing,but looks like that will do the job just fine.

Yep - it's not heavy in the grand scheme of things, but heavy enough to fall back down. I plan to replace the cutout in between the slots with a brass rod, so the line doesn't abrade on hard edges. I rounded them a little with an X-Acto, but a bit of brass would be best. For a first go-round, I am pleased.

Extremely nice! I want to see the access into the head when you have time.

Jason,
How many revolutions does that motor provide -- and is it programmable?
With your current setup, I presume your arm only wants to rotate 180 degree?
If I had my druthers, I would get rid of the arm and have the string go straight to a bobbin that is attached directly to the motor axle? That way you can hoist up that antenna as high as you like, given adequate clear space below the ceiling (ie inside the head of the PD).

Nice vid Jason! The servo slewing range is probably around 90-100 degrees.
I like your pulley system, that will certainly work and not require any maintenance given the string doesnt detach. Plus it will work for any other servo model nicely. :thumbsup
The HS-55 is a good low cost micro servo to use for the antennas. I use them on larger foam RC planes and they have way more torque than will ever be needed for this app.

qcfoundry, the motor Jason is using is a RC hobby servo that only has up to 120 deg of travel (at the most). It has the positioning circuitry built into it so one can command it electronically to go to any position at a given speed.
With your proposal, you would also need some sort of limit switch to stop the free running motor at the desired height. Plus you would need to make the motor run at the correct speed to synchronize with the sounds. That makes things much more complicated.
BTW, they do make continuous rotation servos, but again you would need some way to know absolute position of either the motor axle or the antenna.
In my kit I used the RC servos since it is 1) easier to install and use once the proper linkage is made, 2) everything is synchronized electronically, 3) there are lots of servos to choose from, 4) they are plug and play, easily replaced.
YMMV.

Thanks! I'll have to order another kit from you, too, for my scratch build.
I also want to talk to you about the "ultimate" Spinner light kit, if you're interested. I want to have four of the small 0603 LEDs per police light, to more effectively replicate the real life rotating police lights!!
