Pete,
If you don't program C, you may find PICAXE controllers a little friendlier to
work with than Arduino. The PICAXE boards require more physical prep, but there's
block diagram programming software available that makes getting it to do
what you want simple.

Thanks for all the pointers - I don't have a laptop at present so
figured a small datalogger would be cheaper!

The combination of these two should do nicely, no coding required (but
you can also use them to learn about microcontrollers if you want to):

I made one of these a while back. Works great!

| Subject: | Low Voltage Disconnect needed |
Hi Group
I am need of Low Voltage Cutoff.
Requirements are:
** Ability to handle 10 amps
** When there is a 750mA load, cutoff should occur ~ 11.9 and 12.1 volts
** Minimal parts count, ease of fabrication and low cost
** Somehow once Low Voltage Cutoff threshold is reached, only the secret
reed switch (or switches) can reset or bypass things so the battery
charger (needs voltage to recognize a battery is hooked up ) can charge,
idea is there will be a rare earth magnet in the 12 volt male cigarette
lighter plug (attached to the charger) and reed switch/s on the outside
of the female receptacle on the battery pack)
** Unless the design allows for very reliable use of Mosfet that
isn't going to fail if you look at them the wrong way and even
whisper "static electricity", a relay is fine
Thx.

| Subject: | Adding an electrical system |
I am adding an electrical system to a PT-22 per a customer's request. It w
ill consist of an overhauled Eclipse Y-150 starter, a RG battery, starter s
witch and contactor, a switched bus to power a Becker radio and transponder
, a wind driven generator, and associated wiring.
Does anyone have experience with adding electrical to a PT-22?
Any gotchas?
I can't find any generator or alternator that is approved for the PT engine
, that's the reason for the wind generator. It will only produce about 5 a
mps, so it will barely power the transponder and slowly recharge the batter
y and allow occasional radio transmission.
Since I'm doing a form 337 for the change, I should be able to use any batt
ery. So, we're considering a PC-680 or a lithium ion battery such as the A
erovoltz. Otherwise, we'll us a RG-35AXC.
Comments?
Thanks,
Stan Sutterfield

Here's both all solid state and a relay version
of what I think you asked for. I'd go with the
MosFet version. FETs are quite rugged these days.
