After having some fun with my Bulb- and ISO-Ramper Brampuino 1-X (and having exactly 1.5 users), I decided to start something new from scratch. The Arduino platform was a nice starting point, but a little bit limiting. The Raspberry Pi should be the next platform for this new device.
First, I wanted to support more camera models and had a look at libgphoto2. Very nice; lots of cameras supported. And it runs on a Raspberry Pi!
Besides standard Bulb- and ISO-Ramping it should support HDR to keep highlights, while shooting from day to night, and it should cooperate with the Dynamic Perception's Dolly Engine MX2 - even while shooting HDR!
BramPi 1-X was born. At least in my mind.
A short list of must have features:
- Shutter-Controller via cable-release "port" and camera's X-Sync (this means extra hardware)
- Bulb-Ramping
- (automatic) ISO-Ramping
- HDR (keeping ISO as low as possible)
- MX2 cooperation
Additional should have features:
- Hardware clock (RPi does not have one)
- time lapse XML protocol file
- disabling camera's X-Sync without a terminator
So, here it is. BramPi 1-X's first demo/test time-lapses:
Bulb- and (automatic) ISO-Ramping (check the overexposed highlights):

Bulb- and (automatic) ISO-Raming and Bulb-HDR (check the highlights; the flickering should be fixed now; it was a hardware bug)

All the above features + MX2 cooperation while shooting HDR

Current state of development: BamPi 1-X is an ugly board, but fully functional. Besides the Shutter-Controller and the real time clock, it has a 20x4 LCD and 6 push buttons for user interaction. But a touch display would be much nicer.
I do have a fritzing and an Eagle schematic. I'm working on the layout and hope to make some boards within 4 weeks.
What do you think? Any features, that I didn't think of?
