What is the error message you are getting with RAWanizer?

I don't know how fast you expect the Toshiba to be but my 64Gb cards do 1080p 24/25p without skipping a beat even with global draw on. If you're dropping frames play around with the picture size settings in the Canon menu. Large jpeg seems to work well for me. I'll have a 64Gb Lexar 1000x in a couple of days, I'll do some max frame rate comparisons.

What exactly does changing the picture size/quality do for ML RAW?  Do we still get the same data onto the card?  I notice the buffer has more ticks now after switching and I don't drop frames at all even on first go.

Don't mean to digress from the development chat, but what so you suppose the cost would be to have a manufacturer develop a one-off prototype for this?

I'm working on that.

802.11n is rated at max of 150Mbits a second that 150/8=18.75MB/s which is far to slow.  Gigabit LAN is theoretically possible to pass 125MB/s BUT would require about the same amount of work to make a CF to SSD controller to make it work at those speed continuous.

So the guy replied.  Said Arduino wouldn't be the best bet due to speeds we are trying to achieve and suggested we use a faster chip board like raspberry pi which is more complicated in terms of software BUT has a simple distro of linux running on it and a 700MHz ARM chip.  However the guy did say that this type of thing was way out of his league.  I will research a bit more!

Question: How is the camera interfacing with the CF card? Is it IDE or one of the other types?

I've also reached out to this guy: http://sbc.rictor.org/index.html since he seems to have a lot of experience with these types of devices.

This forum thread is where I found him. ay shed some new light on this thing: http://forum.6502.org/viewtopic.php?p=8343&sid=a06dc948bd456b223cf8a93d175d37e1

Honestly I think something like this will require some custom made interface components.  I am getting an Arduino soon for another film related project so I will do some digging about on the web for anyone else who has tried creating an IDE controller with Arduino.

Found this already.

The file is probably opening into your browser.  Save the file then move it to your modules.

does that CF extender you purchased support 150+ MB/s pascalc?  That's the main issue I am running into, trying to find an extender that holds up to the speeds we're trying to achieve.
#11
Building a small power supply with a battery would be a breeze for this project. I wouldn't worry about adapting to a USB3 HDD enclosure due to portability with power.
#12
Much appreciated!  I was looking for a non-discontinued CF ribbon cable!

Hi all,
I just ordered all that stuff.



I'm going to make the small board to connect the CF extension to the ide port.
If it works, my idea is to build an enclosure, with my 3D printer, that replace the removed door, protect the ribbon that have to point down and maintain safely the boards and DD under the grip. The aim being to keep it as run an gun as possible.
I have a question about alimentation, how to use the 7,5v from the grip LPE6 to power up the 5v recording system ?

If you don't mind me asking, which CF extender are you using?

@ 1080p sometimes the buffer fills after a couple of seconds on the first recording but after that it's rock solid. I'm shooting mostly 1920x840.

Yea, I figure that initial recording frame drop happens regardless of card speeds. Good to know its solid thereafter though! Thanks for the info! I'll pick one up!

The Lexar 1000x and Toshiba 1066x are the top performers.

A1ex have you done the funky graph on the Toshiba benchmarks I submitted?

Do you ever get dropped frames in 1080p with the Toshiba 1066 64gb card?
#16
No, the controller as well as the memory chips are both responsible for the speed of a particular card.
#17
Has anyone found the 5D3 service manual?  I found this Forum post: http://photography-on-the.net/forum/showthread.php?t=1216590 and there is a parts manual but no one has posted the 5d3 service manual there.  Was hoping someone here was more successful.

I saw you guys were posting other stuff from Sycard but I didn't anyone mention this: http://www.sycard.com/cfext182.html  Seems to be simple enough to just extend the CF card outside the case. Would you think it could handle the throughput?
#19
I see you guys had posted links to these earlier: http://en.esskabel.de/adapter/datasheet/ada-compactflash-extender-0430fpc-dma/77/ but were not sure if they could handle the correct speeds. Has anyone found any cable extenders that work/maintain optimal speeds? I only ask because I have been testing a few cards by simply putting them in the freezer for a very brief amount of time and I am able to squeeze quite a bit out of them and I'd like to try marrying a Peltier wafer, http://www.shop.customthermoelectric.com/00711-5L31-06CB-Thermoelectric-Peltier-Module-00711-5L31-06CB.htm;jsessionid=84C65D1ACCFCCBBDCC0A9CB276A75BF5.m1plqscsfapp01?gclid=CNPXu-_4qLcCFYLm7AodqSYA1w, to a card outside the camera to see if I can test some more.

could you please tell me where to download the latest firmware currently available? thanks

Not sure what build you're running but here is the thread that mostly keeps up to date with the latest builds.
