If I connected one of these in line to my battery, will I be able to see how that particular battery behaves supplying current/voltage to my install? In particular, I'm interested in getting an answer as to whether a 4 cell eneloop AA pack can handle my needs in my older plane. Of course, there won't be any pulse width signal.

The unit would still pick up a pulse signal, as it's used for timing the sampling (synchronising with peak servo movements), however you can ignore it of course. It would indeed work for your planned application.

There are only two wires from the battery.. no signal. Where would it get the pulse signal.

Thanx.

Oh Sorry, my wrong there, I was thinking you were going to plug the unit into a spare channel/slot on the RX ( I see you did say battery in your thread, I misread). I need to adapt the firmware slightly to make it change to no-servo logging if it doesn't detect a signal within 10 seconds of startup.

Hi Paul -- just staying in touch for progress on the SLOGGER. I don't see any updates, so I'm guessing you're still waiting for replacement boards. Did you ever really get a handle on the rebooting problem, or was this a SWAG with hope?

The decoupling did help the reboot sitation, but it's all rather a bit too strange, there's no reason for the unit to reboot on such minor wiggles on the rails. New boards should be here soon. I'm thinking of sending the rest of your gear out this week rather than holding everything else up - that way at least you get some Christmas presents!

Goodies are always welcome/fun. I'm also good to get it all at once, so suit yourself. I have lots going on, so I'm not being held up waiting. Hang in there..................... R

BTW -- regarding your path toward tools to diagnose control system issues:

I spent the afternoon helping a buddy pull a motor glider out of a tree about 60 ft up. I've only been in this hobby for ~3 years, and I can't even count all the loss-of-control crashes I've had/seen/worked. He was flying along fine on a major brand 2.4 GHz radio, then it lost all control. It circled the field about 2 minutes with no control response, then took off for the tallest tree. No control reestablished that whole time, but control surfaces responded fine when it got back on the ground. I'm just know that I can find these weaknesses/faults, etc before they crash a plane. It's just a matter of the right tools/techniques (?) There's no sicker feeling than watching a plane crash with no control response.

That's something that always confounds me.... how the gear starts to suddenly work after the crash

If there wasn't a physical weak point before the crash that caused the issue, there sure will be now

New logger boards are working - got one running a test now, isn't dropping out or doing strange things like the previous ones *phew*.

Sounds great. Congrats -- I know you were worried 'bout that.

Just a thought -- if you connect the SLOGGER between the BEC and the RX, would it log the net current load of all the servos?
