I see now!!!!!!!!!! It all makes sense! How do you keep your ear cap on?

The three circles on the helmet are three rare earth magnets, that match up with three magnets on the ear cap. IIRC it was BKBT that came up with the magnets in the ear cap trick.shortimer52 said:

Cool Gator! That's precisely what I was Looking for! I am still unsure exactly how this is going to be set up, but this gives me some good visual reference. I have the servo, and the zip-zap for a controller. Now I just have to fit it all in and wire it up. Here's a pic of where my bucket is at now. What you can't see is the back, which i have to re-pain because I'm not satisfied with the green shade.

Hey Gator, did you have to buy that servo horn seperarely? I got Hyperdyne's servo, and I was planning on doing the same thing as you, but the horns that come with the servo aren't that long.

Yep. I went to my local RC shop and searched through all of the various servo horns, that would fit my servo, till I found the longest one they had. I picked up the package of horns and a seperate package of longer screws. I don't remember the type right now, but I will check when I get home tonight.

OK, I have determined that my servo wll fit in place. Now, my question is what exactly do I need? I have the servo, I have the zip-zap car as the controller board and transmitter; I have read that 2 AA batteries will be sufficent for power Are there any other components that I will need? Thanks again, to the people with knowledge about this stuff! It really helps, and will make my suit look that much better!

Sorry guys.Gator Fett said:
I checked last night, but I did not keep the packaging that the horns came in. Your best bet would be to find a local store and guess the size needed for your helmet.

One question for you first. Is the zip-zap car controller board still connected to the cars little motor? If so, how many wires are connected? If not, are the wires still available?Shinobi_Fett said:

Well, I will try to get some pics up of all my starting materials. The car is still in car form, I have to dissasemble it. (The re is a tutorial on that around, I think) Also, I need to know what part of the transmitter to rip out. (the transmitter/charger is a big clunky thing that the car sits on) That part, I think I want to mount to the inside of my gauntlet, though I'm not certain how or where at this point.
Say, anyone else think there should be an "official" helmet servo thread sticky? All this knowledge should be right at hand as a base building step. Just my thought...

Actually I had a question on the same lines. I still need to look for another car to hack up (may end up using the Zipzap this time around), but the ones that have seen, running a simple motor, only have the two wires coming out of them. The Hitech servo from Hyperdyne has three. I don't a ton about servos, but do I need to worry about the yellow one (which I've been told is for pulse and is specific to digital servos), or can i just snip that off and wire it up like I did with my reguler old servo?

I am by no means an expert in this, but this is what I have learned so far. :facepalm A standard servo has three wires, red / black / yellow. The red and black are the power wires, and the yellow is a pulse (or control wire). With out the pulse a servo will just go round and round, like a motor, as long as power is applied to the red / black wires.
In my kit, I press the transmitter button once, and the servo moves the programed 90 deg rotation, up or down. *Here is where I am guessing.* Without the control wire, a single press of the button would only move the servo a little bit, OR it would start the servo up and not stop until the RF hit its limit or you pressed the button again. Without the control wire you may have to hold the button down until the RF gets to the positon you want. Then to reverse the operation you would have to use another button, to reverse the polarity of the power wires and control the servo in the other direction. Again, I am guessing. :facepalm Hopefully someone with some real knowledge will chime in.

Ok I figured it was something like that. It's a little more covenient with the Hyperdyne kit, only having to press a button for it to go up.
If you don't use the pulse control, you just need to hold down the up or down buttons until they reach the desired position. I use a three-way toggle switch; flick it one way and when it reaches the bottom/top I flick it back to the middle to stop it (or the motor will keep running and burn out). Does that make sense? Its not as simple as the pulse method, but it only takes a second to go up and down so it works for me.

Hey Gator Fett,
That's exactly how mine works..."hold the button down until the RF gets to the positon you want. Then to reverse the operation you would have to use another button, to reverse the polarity of the power wires and control the servo in the other direction."
Again, I used the Zipzap tutorial.

Well, my servo has 3 wires, black, red and blue... what are they? I know that black is almost always ground, and red is power. Is the blue the pulse one? Just becuase I am electrically inept, that I ask so many questions! Thanks follks!

Actually black is NEVER ground. GREEN is the ground wire in an AC / DC circuit. In a residential AC circuit black = power, white = neutral and green = ground. In a DC application black may be power, neutral or some other use, but not ground. In your application, the black/red combo are the power/neutral or neutral/power (depending on how the circuit is wired) and the blue is the pulse.Shinobi_Fett said:

OK, I will be using the zip-zap car method. In these pics (lifted from Krillin) it shows red/black going to the battery. Do both go to the same battery terminal? He recommenends a bettery caes... There are blue and yellow wires rom the controller board, what wires do those go to on the servo? Blue to blue? Is the yellow unneccesary? Help! (Thank you for all the help thusfar!!!!)
