Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

i am just guessing:

the program is REFRESH. so you get 3 values, charge1, discharge1, charge2. to some users it is not clear which of these values is displayed on the End screen of mc3000 device vs. mc3000 android app

I've managed to get the internal temp for my MC3000 to 70c (and fan on high) just discharging 4 x 18650 at .75 mA - then I put a laptop cooler (big single fan) under it and got it down to only 60c.

Seventy degrees Celsius (158 F), discharging 4 x 18650 at even less than 1A/bay discharge rate?

That's horrible thermal management.

Just got my MC3000 from Gearbest!

It comes with FW1.3 which I assume is the latest. It is a HUGE charger! With a steep learning curve to operate. The settings in the smartphone app (Android and iOS) are not as detailed as those in the unit itself.

So I just got my SkyRc MC3000 in the mail and I think there's something wrong with the fan, it has a buzzing sound coming from it, I took a video of what the fan sounds like.

Mine sounds exactly the same. Have you found the problem? Solution?

 

[amf14]

That's very clever. I'd been using my older MC3000 with snapped posts with some random pieces of fill to achieve contact. Took it apart and put some cable ties in there, but must've shorted something out while putting it back together since now I get the following error from the ADC (MCP3424-1 Err). Tried reassembling it and checking that everything's ok, but the charger doesn't seem to recover from it. At least I have a spare...

Same problem here. Any Solution to this? Thanks.

Regarding MCP3434 error - this might not be the issue but make sure that no USB cables of any kind are connected to the unit before powering it on.
If you have a usb cable connected between your computer and the box, before applying the main transformer power, the unit will "appear" to be on but non-functional.
That is due to the 5v of power it is getting from your computer over the USB cable.

Hello,
I was wondering how you got DataExplorer to work with the MC3000?

Do you use a USB to TTL Serial converter?
Is there a post somewhere explaining the steps to connect the MC3000 to DataEplorer?

To me, it appears that DEX is expecting a Serial Port...not a USB HID port.

I tried just connecting several USB Data cables but that didn't seem to work.
The Only Ports that show up in Device Manager are HID and those do not show up in DEX.
There must be some extra steps?

Oh, the PC Link software connects just fine and works well so it "probably" isn't the USB cable.

Thanks

Nope... nothing about a Serial converter... Just an USB cable...
Have you configured it??... You must go to Device selection and port configuration and choose the MC3000-Set device. There is a message where is explained very well. Let me to search it for you...

Just a question for you...
Is the MC3000 Monitor working?? Have you tried it??

I think there is another one more extended... but this would be useful anyway

Thanks cpa :twothumbs

I believe I had followed those steps and it didn't work but I'll follow the steps posted verbatim and see if that makes a difference.
Will give it a try again today.

r u on Windows?
basic troubleshooting on Windows:
- you need to have the latest Java Runtime Environment JRE installed, see java.com download
- the bit-version of Java must match the bit-version of DEX (32-bit Java for 32-bit DEX, 64-bit Java for 64-bit DEX)

After pressing "Start gathering", the DEX software waits for data, so you must press <Enter> on your charger.

@cpa , my raspi alu case got shipped , will take at least 4 weeks to reach me through Surface Mail . I am planning to review it and youtube , will be some phun! :naughty:

cpa...you da MAN!

I followed the exact instruction syou posted and now it's logging data so....

Thank you so much ! :twothumbs

Yes, thanks
Must have simply been the ORDER in which I was connecting things.
All good now!

I opened my unit and found nothing rubbing and everything looked good, I put it back together and the fan buzzing noise was gone :thinking:

I have no idea what was causing the problem, but just opening the unit fixed my fan issue.

Good to hear you fixed it. Good work.

MC3000 charger-analyzer - Changing the log entry interval

I've been reading the manual and searching this thread but come up short.

I'm trying to reduce the number of log entries in the TABLE VIEW from one every second (or so) to one entry every 30 seconds.

Time Base / Time Step does not seem to change to actual sample interval.
In the Time Base Screen under Time Step I have a units of msec (milliseconds) and 1.0.
So I assume that means the logging interval is ONE Millisecond....or 1000/of a second
So, I thought changing the Time Step to 1000 would change the log interval to 1 second, therefore changing the Time Step to 30000 would make the log interval 30 seconds.
Didn't work like that.

I've tried adjusting the settings in the configuration and preferences that I thought would do that and it seems it did change the displayed time interval on screen, but the entries were still coming every second.

Where in the manual can I find this information or where in this thread?

Thanks

Re: MC3000 charger-analyzer - Changing the log entry interval

I've been reading the manual and searching this thread but come up short.

here my take: you're talking about DEX logging and DEX manual? DEX code samples at exactly 1.0Hz, it is a code cycle thing and also natural to DEX or mc3k api. it is obvious that one cannot increase the (whose?) sampling frequency indefinitely, there has to be a limit. having said that, 1.0Hz is perfect for this logging system. now you want to reduce the logging sample cycle down to once very 30 seconds. that's so low that i don't even know how many Hertz that is. so my take is that i take the 1Hz and be happy. and if i wanted a table with only 2 data rows per minute, then instead of trying to figure it out with Excel i'd launch mma since it sits next to dex anyway (on the raspi, at least lol) and take the 2 data rows with ..lemme think.. probably with the Take command. i am not an expert DEX user so maybe we're overlooking how it could be done in dex the very.

maybe my take (mma solution Take) s*cks, so if anyone knows how it's done conveniently in DEX or in Excel, please share tanks!

Ok. I thought this would be something as simple as just telling DEX to only selectively record a log entry at the interval the user specified...ie...30 seconds, 1 minute etc
For my purposes, I don't need a log entry every Millisecond. Too many entries. But I'll find a way to filter the output file if necessary.

I wonder why DEX has a place to change these values if it has no impact on output?
Oh well. Maybe someone else knows a way?
