I've been working on a line of new products for the

AeroElectric Connection website that will be unique

to AEC. We're going to resist being a dealer for other

folks products.



One project utilizes an ECB and enclosure that has

features described in these two illustrations:

http://www.aeroelectric.com/DIY/Do-Much_Board_Schematic.pdf

The schematic would never have ALL components installed,

and in some cases, components left of are replaced with

solid jumpers. However, depending on what parts are installed,

their values, and what software is installed in the microcontroller,

we can craft a variety of products with 98% commonality

of bill of materials.



The first product to be offered under this design and

marketing philosophy is described at:



http://www.aeroelectric.com/Catalog/AEC/9011/9011-700-1C.pdf



. . . except that it will have a 15-pin connector on it

instead of a 9-pin.



I'm publishing the schematic for the more technically

inclined. Perhaps the architecture will suggest an application

close to your own wishes for a smart black box to do some

task. If so, let's talk about it and see if my software

guy can't whip it out in reasonably short order and save

you a lot of development time to craft a nicely packaged

electro-whizzy. Or, if you want to do your own byte-pudding

I could offer you a kit of ECB and enclosure from which

you could move your project ahead.

This may not fit into your philosophy of versatility but FWIW if I were 

in the market for the LV/OV control board I would prefer to see the 

lights and switch already mounted within the module. Second best would 

be a pre-wired remote panel of lights and switch or at least the option 

of purchasing those unassembled parts at the same time.  I have learned 

that it is nice to have all such remote assemblies of switches or lights 

easily removeable as a unit for serviceability rather than mounted in 

individual holes in the instrument panel. In addition where I've used a 

single DB connector on a device for both power and a remote panel, I've 

found it difficult to remove the remote panel for service or 

modification since the connector is also hardwired to the aircraft.



We have completed 130 flight hours with our Z-14 wired subaru now 

without any nuisance OV trips.  The only electrical issue is that I 

recently purchased a comfortable David Clarke headset and with our 

fairly quiet engine, I now hear weak but annoying strobe whine that I 

couldn't hear in cruise with other headsets. I have already followed 

most of your wiring recommendations so it may take me awhile to solve 

this one especially since the strobes operate off a different alternator 

and battery as the radio and intercom.

   Keep in mind that the Do-Lots assembly is capable of being configured

   for a multitude of tasks . . . many of which may not even have lights

   and or switches. If I were addressing the single application cited, then

   yes, avoiding the remotely mounted electronics module would be desirable.



   One could always configure their own installation with the necessary

   and useful in-line connectors to accommodate a maintenance situation.

    Start with a test battery made up of a couple 6v

    lantern batteries to run the strobe supply with a

    short cable and batteries located right at the power

    supply. You need to deduce the propagation mode. I suspect

    it's conducted and a relatively simple filter at the

    power supply will fix it.
