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?

Re: My DIY Bulb and ISO ramper Brampuino 1-X
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.

Hi Boris, I didn't see a pdf of the manual and I looked around for a bit.
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Edit: I replaced the link to the outdated manual by a link to the downloads page, because some people downloaded the old version.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.

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? Rafael

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.

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.

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

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