Help with wiring diagram

[Jazkal]

Here is what I'm trying to do:

I want to have a single battery system for my marker setup. Currently, I need 3 9v's and 6 AA's.

Instead I want a single 9.6v battery to power everything. The problem I have, is that I can't figure out the wiring diagram for what I want. I'm hoping some of you modders can point me in the right direction.

Here is my setup:

Bushmaster - Uses one 9v
Halo B - Uses six AA's
Warp Feed - Uses two 9v's

All hardware has 9v connectors.

My "One" battery is a 9.6V 1800 mAh NI-MH rechargeable.

Can someone point me in the right dirrection?

Thanks.

Not really feasible, though it is possible. You'd have to use a step-up transformer to push the 9v up to the 18v that the warp wants to see (it's actually 12v, you could step-up to there but you'd have to change the warp's wiring)
The other two are simply a matter of running the wires.

The problem is, you'd put such a load on the battery when you shot off a string of paint that it would either toast the battery, drain your battery obscenely fast, or brownout your warp/halo/bushy. You really need to be able to take a few hundred mA off of one battery for the bushy, a couple hundred more mA off of another for the warp, and a lot of juice for the halo I'm not sure a single cell would be able to provide that load without sagging down into uselessness.

It's doable if you are running the warp on 9v. I would try to get the whole thing running on a 2x9v bigcell in the warp though. Try it.

Have other people gotten this config to work?

That's all I'm saying....

Well, you need to start with the highest voltage requirement (18V in the Warp) and account for the maximum current draw. Then, use a voltage regulator to provide the 9V for the bushmaster and the Halo (but the current rating of the regulator will have to match the maximum curent draw from the two combined).

If others have gotten this to work, then I should be able to get mine to work. I don't see how this is any different from what I'm doing, which is just moving the "Big Cell" outside of the warp.

What I had originally planned, (I'm just not up on electrical circuits, so that why I posted here) was to create four sets of power wires with 9v connectors on them and just plug them into each of the devices 9v connectors. So I'm guessing that this won't work?

Can't say for certain, but it's doubtful you'll get good performance. The reason that the HALO needs 6AA cells instead of one 9V is because of the current draw.

As it is doubtful the HALO alone would work acceptably on one 9.6V rechargeable, it's improbable you'll get HALO, Warp, and marker working on only one.

lots of people are using 2 9v's in parallel for the Halo with excellent results.

And from my understanding, that is just creating a "big cell", meaning it is still 9v (so it won't fry the board) but it has double the amps. Of course they don't last as long as 6 AA's, but still last long enough to go through 2 cases of paint.

Since most 9v batteries are around 150-170 mAh in size, I figured having a 1800 mAh 9v would be more than enough to power everything.

Am I missing something besides volts and amps?

Yes. You've missed peak current draw. I'm not sure that the higher capacity (1800mAh) battery has an increased peak current.

But, if your two 9V in the Warp are in parallel and it's not an 18V mod, then yes you could perhaps just rewire everything to run of one pair of 9V batteries.

So, with two 9Vs in parallel insid ethe Warp, I'd see no problem in just wiring 9V connectors to the Halo and marker. All you should need to purchase is two 9V connectors with pigtails.

Just keep the wiring polarity correct.

Experiment with one battery, but I think you may have performance issues.

Is there a way to measure "peak current"?

Is there a way to measure "peak current"?

Sure, Ammeter, oscilloscope, etc.

Or, you could look up the specifications of the motors. Easier (and cheaper) just to experiment with different battery setups though.

Just don't get the polarity wrong or send too much voltage to any of the boards.
