| Subject: | Just Two Days Left - Still Way Behind... |
Dear Listers,
There are just two more days left in this years List Fund Raiser. Over the last
few weeks I have received some really nice comments from members on what the
Lists have meant to them. I have included some of them below. Please read over
the comments and ponder on your own feelings about the Lists and the support
and camaraderie you have found here.
We are still way behind last year in terms of the number of contributions. I really
want to keep providing these services to the homebuilt community, but it
take resources. Since there's no advertising budget or deep pockets to keep
the operation a float, its solely your generosity during the Fund Raiser that
keeps things going. Please make a Contribution today.
If you've been putting off showing your support for the Lists, now is the time
to do it!

I'm going to need some 12v outputs on my 24v electrical system and I ran across
these.

Does anyone have any first hand experience with these?

Why not consider using two 12V batteries in series and take 12v off one?

| Subject: | Re: PTT Y adapter for RST intercom |
Thanks, Bob and Joe :-)
I've ordered the relay and continuous bus perfboard. I'll post some pics when I
get it assembled.
I also was wondering about the power supply. I'll wire the a/c 12v supply to the
wire connected to the BI terminal on the intercom circuit board. There is also
an option to add a 9v battery for backup, connected to the BO terminal. I have
a 1.2 Ah 12v battery that is used for my EFIS backup supply and wonder if
I could wire this to the BO terminal in place of the 9v. Would I need a resistor
between my 12v backup battery and the BO terminal, to drop it down to 9v? If
so, how do I figure the size?
How would I know the intercom is drawing current from the main 12v supply (BI)
and not the backup (BO)? Even though the small 12v backup battery gets recharged
by the main a/c 12v supply, seems I'd want the a/c 12v supply to provide power
for the intercom.

This has been tried . . . and never works. The batteries
become 'unbalanced' with the top one being over-charged
and the bottom under-charged.

How much total power do you need . . . and for what
systems?
