WB jr. Q&A

[TomW]

No, sorry that won't work.

Each Whizbang Jr. needs its own host Classic to read it.

This example is if you have one shunt and a WB Jr. and a Trimetric or a Magnum BMK etc.

Phooey. I need one AUX2 for Clipper control. Guess I will need to use the single shunt option

Thanks for the feedback.

Well, when Aux 1 gets PWM in addition to its present slower diversion, then you can use one of your Aux 1 outputs for that Clipper and you will have an extra Aux 2 for another WB Jr.

Gee, boB it never truly ends for you does it?  Just when you think you can kick back and relax someone sticks more stuff in your in box!

Hopefully that is a software item not hardware to change how the AUX1 works?

  But we can add more control to the controller like, being able to turn off the charger from
an external input or software communications control of various parameters.    Didn't you request one of those features ?

Then watch out for the "Caption Billy WhizBang" !

Yes I did request the aux input to shut off Classic output.
But then I ran into the not enough AUX input/outputs for everything I would like to control problem.
Which sort of brings me back to my original question - multiplexing AUX2 input and output. Although I suspect from a hardware viewpoint this may not be possible as a single wire connection to the WBjr probably means its getting its power via that wire. I thought that if sampling the WBjr data was only every second or more then some nifty software switching between input/output modes could work. Maybe even the brief disconnection of PWM output may be tolerable in most situations to allow a brief data read from WBjr.
Anway, just my thoughts..

midnite why not design a small niffty componet like the whizbang to give more aux output/input so those who would like to add more output/input to their classic can do so.Just a suggestion .i am not an expert of any kind.

Well, I think you've hit the nail right on the head, Mahendra !

DGD, Aux 2 was designed to be input/output/analog/digital but no multiplexing it I'm afraid to be 2 terminals
instead of one.   But wait !....  Nahhh... nevermind.

Tom, on Aux 1 being able to do PWM, that is a software only issue.  Luckily no extra hardware required.

A really old, crusty tube era electronics engineer once told me the ultimate in design is not when nothing more can be added but when nothing more can be taken way and do what you need. It was a different time and we did not expect our phone to flush the toilet. They were all wired to the wall then, too.

I am all for change as long as everything stays the same while it is happening!

I do like the idea of a multiplexed "breakout box" that would probably be less than simple to build and code for.  You know more uses for I/O will be dreamt up and flexibility and extensibility are great attributes for any system. Despite what that crusty old engineer told me!

Finite resources probably limit what can be reliably accomplished with current hardware, tho.

Just from the peanut gallery.

So each AUX is two pins marked + and - on the Classic BUT are the - pins just connected to the battery - ?  Or is each pin a separate IO pin that gets to the cpu bus? perhaps via some cmos level logic/level changing gates etc to get that 12V logic on state wth decent current carrying capability?  If the AUX negatives are just battery negative then why bother with them as all (most)devices would have a common negative to the battery anyway.
Now if they are separate IO logic pins just paired up with the pins marked +ve to simulate analogue signalling over then the possibilities of having 4 AUX controls with software PWMing etc starts to look interesting.

Without having seen a WBjr my impression is that you may be using a fairly common AtoD device with SLI output with single wire connection to an AUX2 pin. Maybe with power on the same wire or is there a separate + power connection to the WBjr?
The more I think about this then the disital IO pins seems most likely since the MNGP/local app can change AUX logic states...

Now wouldn't that be nice       AUX2 + input to WBjr   and AUX2 - as output to Clipper

I have 3 shunts that I would like to read..
I also have 7 classic controllers, so I have plenty of aux connectors.
Will the classics add up the readings from the 3 shunts?

thanks

It won't add them up quite yet.    That should be a future software addition though.

In fact, I was thinking about this just today !

Sorry though...  I don't have a time frame for this yet.  There are lots of possibilities !

Any way to know which dealers have these in stock yet ? Or when they will ?

I don't think that any dealers have them in stock, yet.

I will try to find out if any stocking distributors or dealers have ordered
any yet  and/or if we have shipped any out to those types.

yep they don't i have checked a lot ,only place i have seen  them is Australia.Funny its produced in the US and an Australian store  already ordered them from Midnite.I should also mention they are very few places that stock some key Midnite accessories e.g Midnite solid state relays.That s a real bummer i say.

[mahendra]

OK for those who want the Whizbang jr its available form ECOdirect.com.As i mention very few stores carry some key midnite Products but luckily ecodirect is not one of them

I called the eco direct - they have them listed on their website but she didn't know if they actually had any yet but was going to get back to me . I bet lots of people are itching to get their hands on one and get it hooked up.
