I'm getting the Strike Freedom Flash soon, and I am gonna need a little external expertise. The kit has two circuits in it, one that is the body and extremities, and one solely for the head. The main circuit is powered by three batteries. (AA or AAA I'm not sure.) The head simply has one button battery in it, a la PG RX-78. Anyhow, I want to tie the head into the main circuit, much the way it was done on the PG Mk-II. Does anyone know if I need a resistor or something for that?

 

you mean the "Lightning Edition"?

combining the circuits, no idea how you'd do that. the head doesnt have any wires, and the neck is just a ball-joint and doesnt have clearance for wires running to the body.

 

If the ball joint were big enough, you could probably drill a hole through it and run the wires that way.

As far as the wiring goes, if the voltages are the same in the head and body, you should be able to loose the head battery and run it all off the body battery.

Now that I read it again, if the body is powered by 3xAA, the voltage would be 4.5 volts, and that's more than a single button cell produces.

You may need a resistor to cut the voltage down to whatever the head battery produces. As far as how big the resistor should be, I have no idea.

You may be able to go without the resistor, but you run the chance of burning out the LEDs in the head. It all depends on what they can tolerate.
If I were you, I'd test them with 4.5 volts and see what happens, just make sure you have spares.

 

Well, the head button battery produces about 1.5 volts, if I remember correctally. (a CR1220, I had one in my PG RX-78) The other thing I want to do it wire it for USB. A USB power cord runs about 3.3 volts. That'll be enough to power the body ad the head, especially if I put a resistor in the head to cut power to 50%. As for that, the Strike Freedom has quite a collar, plus a flange around the head, so that should cover up a couple small wires.

 

A CR1220 is 3 volts. MOST leds work fine upto 5 volts (or even 12), but if this kit is anything similar to a PG RX-78, the head-led is probably a 3mm type. Some of those are 3 volts max.

 

3 volts? That's perfect for USB. Of course, if I'm going to be stopping by a Radio Shack anyway, what's to stop me from getting a better LED?

 

a better LED? dude, the LEDs on the lightning edition strike freedom are really good as they are.

go to dalong.net, click on seed, click on the kit you're talking about in here, and its on page 2 of the photos all lit up. As you can see, they're really bright, even managing to shine through several layers of plastic. the thing would make the coolest night-light ever.
