Sound Module Battery Eliminator + Distort Fix

Hello fellow builders,

This little 2"x2" board came from the desire to run all of the lights, the sound module and an audio power amp from a single battery; 9.6V, 12V or even up to 24V.

It addresses problems both I and others were having and is documented over in GBFans.com

Attach this board’s +Vbat/GND screw terminal connectors to the main battery that is also used to power the the amp and light kits. This board has separate screw terminal connectors to provide power to the sound module (I used Crix’s sound module) and also separate connectors to receive the speaker driver output from the sound module. This board converts the sound module’s output to a standard Line Out level signal so it can be used with just about any audio amplifier without the distorted sound you may experience if you connect the sound module directly to the amplifier.

V1.1:

There was a potential issue when using the higher voltage batteries with the V1.0 of this board that has been fixed in V1.1. The pre-amp bias is now reference from the 3.3V internal regulator so will not provide higher than desired bias voltages when left unconnected, and will not be able to reverse bias the sound module’s speaker outputs.

PRICING:

Ready-To-Go: The price per fully Assembled and Tested board (as shown in the photo above) is

$30 SHIPPED within the USA.

$35 SHIPPED anywhere (just about) worldwide.

Bag-O-Parts Kit: is no longer available..

The Bag-O-Parts Kit does require you to load and solder the components on the printed circuit board (PCB). The PCB is a high quality 2 layer board with plated through holes, solder mask on both sides, and a silk screen showing parts values and placement information.

AVAILABILITY:

In stock!

Here is the wiring diagram:

And if you use a battery that provides a voltage that the light kits also can use (check with the light kits makers to see what voltage they can handle), then here is a diagram showing where to connect the lights into:

Depending on the lights you have, you may want a separate power switch between “+Vbat to lights” and the lights power connection so they can be powered down separately from the amp.

I’m in a for a bag-o-parts!

2 x ready-to-go’s with international shipping please :slight_smile:

…do you combine shipping? ie $65 for the 2 in the same shipment… or is it $70 for 2?

thanks heaps

Im in for one. I get paid on thursday.

6

Oh wow, nice! Even after the protoboard I got from you, this is REALLY REALLY enticing, if only 'cause I don’t wanna be running 26 AA’s…

VERY nice looking boards! May they give unprecedented clarity to people’s audio!

7

Actually came up with some funds and I am ready to pay now for on fully assembled. Whats your paypal so I can send u the payment.

8

Looks great, I would like to get 2 of the “Ready-To-Go” version. Let me know when you want payment

I need at lest 1 as a gift, can I get it in time for xmas?

This is awesome ,just one question …as I’m not to …electronics savy…is this a passive circuit which simply cuts and redistributes the voltage.. or does it also consume power.

11

Consumes power.

12

I should have no problem running 2 different dedicated battery packs as l planed one for lights, one for sound / amp. And it eliminates the need for the AA needed for the sound chip …so I should put two main power switches on the mobo to cut power to this chip also …? Correct.?

Hello Skully,

I run everything off of just one battery. If you desire to use separate batteries for the Lights and the Sound/Amp, only one switch (or pole in a common switch) per battery would be needed. The Sound/Amp battery positive terminal should go through a switch and then to both the AMP and the pre-amp board. The Pre-amp board will power the sound module whenever the Pre-amp board has power. No Need to separately switch on/off the pre/amp or sound module.

The “Grounds” (GND, common, and negative side of the battery) can all be connected and do not have to go through the switch.

P.S. I may be out of modules - depends on the outstanding PMs I have sent out. I will make another batch that should be available by the end of January. I did not expect much of a response, so only had enough parts for a few of these. If you are interested, I can add you to the Waiting list - no obligation, just a place in line!

16

may I put in for one do it yourself

17

I’d love a ready to go module - this is awesome!

Quick question - would this help solve any issues with the volume control pot picking up distortion over long wiring distances?

18

Sponge …put me down for one …thanks for explaining the answer to my question earlier…The reason this seems so awesome to me is that I cam run a larger amp to my speakers worry free …no distortion created by the preamp voltage of my Crix soundchip..

19

This sounds like a fantastic piece. I was over FunkPunkTwang’s place last night having my pack’s sound upgraded and the distortion was definitely an issue when we had the wires too long. Even now when you turn the amp up too high it gets distorted. Consider me very interested.

I’d like to be on the waiting list for a ready-to-go unit. Thanks
