After seeing that the Little Bramper is sold out, I thought, well now it's time to do it on my own. And there are so many software pieces laying around! I "just" have to combine them. Here is my little Bulb Ramper: Brampuino 1-X.



It's another Arduino-based intervalometer which uses an USB-host-shield to talk to the (Canon) camera. Besides standard intervalometer functionality it supports automatic and manual ISO-ramping. I even added focus ramping but that does not work at the moment with my 5D MkII.

What do you think? Useful?

Nice work Boris, I was wondering how I was going to get into a little bulb ramping. Are you going to publish the code and directions? I would love to build one.

Yes, that's the idea. I'll do some more tests and post an update here on where to find the source code and give build instructions to build the hardware.

Great! I will watch for it.

me too, looks great!

This looks pretty great! Can't wait to try it out myself

It's online: https://github.com/borisboesler/Brampuino-1-X

I uploaded a draft user's manual in PDF format, you'll find it in the download section, with a list of required hard and software.

Have fun,
Boris

Hi Boris, I didn't see a pdf of the manual and I looked around for a bit. I did download the files though Thanks.

This is fantastic, thank you Boris!

There is a hardly to see "Downloads" links on the page (do a text search for "Downloads"). At the bottom of that page you'll find "Download packages" and a link to the downloads page: http://github.com/borisboesler/Brampuino-1-X/downloads

I hope this manual gives a short overview.

Edit: I replaced the link to the outdated manual by a link to the downloads page, because some people downloaded the old version.

.. and it's got it's first bug fix. Available on github.

SWEET! Exactly what I was needing, thanks. Can't wait to get this together.

Very nice work! Can't wait to see where you go with it in the future.

would it be possible to integrate your code into the MX2 code? that would be fantastic.

Hi Boris
I am following your thread and hoping you achieve all your future enhancements
this is really great work
are you able to change aperture value through the usb on the 5d2?

There are many things to consider:
memory: at the moment MX2 has no (or not much) free memory; even B1X's firmware is 28k; this would imply a board upgrade
pins: I think MX2 has not many free pins and the USB host adapter needs additional pins; again this could imply a board upgrade
camera: MX2 is camera neutral, B1X is not. Well, the generic PTP code could run several cameras.

So, the answer is "probably not".

If I had to start such a project now with the new requirements etc, I would consider to use something like the Raspberry Pi; could be cheaper and simpler. But that's just my opinion.

Thanks.


Yes, the "only" problem is "in which order are the three values exposure time, aperture and ISO ramped?" or are they ramped simultaneously? At the moment the time is ramped until the maximum/minimum exposure time is reached, then this ISO is increased/decreased and the exposure time decreased/increased.

Ramping the aperture is possible with EF lenses only and that was said to cause flicker. For that reason I use manual lenses and have never thought about aperture ramping.

I've uploaded a new test on vimeo. Nothing special new, it just shows the stars and the milky way at the end of the clip.



Short User's manual is available on: https://github.com/borisboesler/Brampuino-1-X/downloads
The link above points to the oldest version.

That makes sense Boris thanks for the reply.
keep up the good work

for combining bulb ramping with the DPS0 try THIS THREAD
that should do the trick

here some recent information about the brampuino!

http://www.eiseman.de/brampuino-1-x/

Have someone tried to follow the tutorial and build one?

I have:

Bit of a thread revival...

Anyone had any joy creating one of these? Certainly looks promising!
