Hardware and Accessories / Re: Powerbank

If the step-up converter sticks out of the powerbank attached only to the USB connector,

Just for clarifying:
The adapter in post Reply #16 and Reply #19 is not a DC/DC step-up converter! This adapter communicates with the power bank and only tells it that the power bank should supply a different voltage. On QC 3.0 it can deliver 8.4V / 2A.

The adapter on Reply #2 is a DC/DC step-up converter and works with 5V Powerbanks. But this one only dilvers 8.4V / 1.4A which is not enough for my 6D

it will break very easily, especially if you move the camera around.

Two ways to get around it:
You remove the plug and socket of the adapter and replace it with a piece of USB cable. This is my favorite solution
You could use the adapter with a Y cable. The adapter only needs to communicate with the power bank once at the beginning until the 8.4V comes in. Then you can theoretically pull it off. But I have not yet produced that. 

Here you see other solutions with Quick charge. This adapter also prevents the power bank from being switched off in standby

How much current does your 6D draw while video recording with Global draw ONthis adapter also prevents the power bank from being switched off in standby?
I never used 6D with video. Only time-lapse.
But with the Adapter in Reply #2 the cam goes off when the mirror goes up. So 6D needs mor than 1.5A.

"I made more tests yesterday, I think 8.90 Volt made the camera overheats quicker than usual, I re-added one diode to drop voltage to ~8.55 and that was fine and it doesn't overheat quickly it was normal,
Really?
I never notice this on my 6D. If I increase voltage, the current goes down.
How du you messure?


Could you please measure the exact voltage in this 8.55V scenario under load,

Is this not possible to log voltage with ML?
On my cams with CHDK I contionus log input voltage und temperature in a file.



If you can find a powerbank with adjustable output voltage (7.5 - 8V) and 2A output capability, that would be the ideal solution - powerful, compact and no casing required.

Do you read my  Reply #16 and Reply #19?

Every cheep Powerbank with Quick Charge 3.0 can do this. With Quick Charge 3.0 you can set the voltage in 0.2V steps to 7.8V and 2A.
You must only tell the powerbank, that you need 7.8V. That is what the quick charge USB tester in Reply #19 did..

My concern is much more the smart charger that I will have to build to protect the cells when charging.  I'll check and see if I can find 3,7V cells with built in overcharge protection circuits inside.  If someone has used such cells, please share your experience here.

I thought every 18650 cell contains a protection against overcharging and deep discharge. I once had some that definitely had this protective circuit.
After these cells were taken from me twice at the airport security checkpoint, I only use power banks.
Short Answer: Welcome to Syria :)
Ok then I understand…

But has nothing to do with the topic of power banks, does it?

I bought my last dummy adapter for less than 5 € in China..

Can you find a way to reproduce it?
Not always…
I used LV in M Mode and continuous shooting s.
I look like, it is only happening with Frame Autodetect. If I change to 7 Frames, I haven’t seen it until now.

This is the first time I've had a crash with ML on my 6D while using the Advanced Bracket.
I haven't used the function before.
My version is a bit older. Should I update something first?

Would be interesting to know whether you could also switch off the crop mode for EFS lenses.

No link given and therefore unable to check source.
If it is important and something changes, then I can look for it in the CHDK forum.

They could have done so back in 2012, when we were accepting donations, or in 2013, when we've got a massive popularity spike after announcing …
Thank you very much for the detailed explanation.
As an enthusiastic CHDK and ML fan, I naturally hope that it will continue ...

Update: just received an e-mail from Open Collective, titled: " We can host Magic Lantern! "

In the CHDK forum I once heard the statement that as soon as CHDK became more commercial, Canon could protect its cameras better for debugging. Is that to be expected here too?

Thank you, good to know that the highest temperature is in the EXIF data ...

I am using RAW Therapee which cannot read EXIF data from CR3 RAW files, used on newer canon models. Therefore I cannot answer that right now. If someone knows another free tool which can do that, please let me know!

Code: [Select]
exiftool -h IMG_1234.CR3 >t.txtWrites all EXIF Data to File. Then you can search for Camera Temperature

Displays the values of several temperature sensors. TEMP(A) seems to be the sensor of the main CPU.

It would be interesting to know which temperature value can be found in the EXIF data of the RAW file.

13
So far confirmed to exist on:
PowerShot SX740
EOS M50
EOS R, RP, R5, R6
EOS 250D

Works as well on EOS M6 Mk2, G5X Mark II and  90D.

Joerg, have you been able to run that script on EOS M?
No the Script runs only on M3, M10 and M100.(I wrote the M with CHDK).
The link was only intended as an example to show what to look for..

I would just shoot with my mobile with Lightroom you also can you get RAW pictures.

I have never seen a mobile with which you can make reasonable time-lapses directly in the sun. There are usually a lot of flares and the core of the sun is very washed out.

Hi everyone.

I am a fan of Timelapses and for now i have used qDslrDashboard with my 5D3.
Everything is going well but if, for exemple, a car passes by, ETTR will adjust the shutter speed and will make it shorter for the next picture.
I would like to avoid that.
 

There is a very good time-lapse script for the EOS M with CHDK, in which you can set the maximum size of the changes in EV (Max Ev change).

I wouldn't be surprised if ML couldn't do that too.

Because there it is clearly pointed out that you can not use EOS Utility to downgrade 1.3.6 I strongly suggest to re-read said instructions and begin following them.

Since EOS Utility works for downgrading the R6, you should test every camera with it.

Does it really?

With the reference to this link someone tried it in the German DSLR forum:
With the R6 from 1.2.0 to 1.1.1 it worked eos utility .

19
What is the advantage of this method?
With eos utility a Downgrade works also...

I have now bought the following adapter:
https://lygte-info.dk/review/USBmeter%20QC2-QC3%20trigger%20UK.html

Work really well. They remember the last setting and you can use Quick Charge 3 to set the voltage in 0.2V steps.

21
At the moment CHDK cannot be reached at all ...

22
I don't have an R yet myself, but the menu is locked with EF-S lenses. This is not a problem with Sigma lenses. The EF-S 55-250 works really well with the 6d with intermediate rings.

23
Would it be possible to switch off the automatic crop mode with Canon Basic if Caonon EFS lenses are connected?

Interesting. Shutter count also broken here or has some encoding scheme.
Looks like this...
But only on RP.


It meight be interesting getting a dump of a fresh RP with 0 shots taken to find out the origin value.
Yes, would be intresting...
All my M's and 6D had 0 on the biginning.

Counter increased by one but is still invalid.
Intresting...
Maybe the memory is brocken.
Would be intresting to see a dump from an other RP.
