The ultimate timelapse camera controller

Man, you've really read my mind - I've been telling Jay I want to build a linux SBC-based device running gPhoto for a while now!

I think it's a great idea, I'm just not in love with the NanosG20 for that price =( For about the same in USD, you can get the new Pandaboard, which is like the Beagle, but has a dual-core 1GHz processor. Follow the chain with gPhoto, dual-core 1GHz proc, the Qt GUI I'm working on... =)

If you want to start down that path, I have lots of thoughts on it - I spent some time buying prototype hardware (cheap Chinese MIDs) and experimenting. The nice thing about the SBCs is that they all have a plethora of GPIO, and the linux kernel has good support for all the same protocols we use on the Arduino.

I'm sure Sebastian with the Apertus project would like to see integration as well. He's doing similar work, but for live video and the Elphel camera.

Yeah, but that weak dollar is about to kick my butt - going to Germany and Austria in October!

Any linux board is good for me - but will have to be powerful enough to run a Qt-based GUI, so I'm leaning towards the Panda, although there are some SoC's that are in the 1GHz range, and would be better for a custom build (which I would do for something I sell). I don't put much thought into them right now, as they change rapidly, and I'm months away from starting to design a bespoke linux-based controller.

So, my suggestion is get the most horsepower for designing around: the Qt GUI is going to be designed 800x480, meaning it will fit nicely on a lot of small LCDs, but will be "beefy" in memory and CPU requirements. You already have the communications code from the Qt app you downloaded previously.

Elphel doesn't use the beagleboard, they have a bespoke computer in there, but I think some of the apertus stuff relies on a beagleboard in addition to the elphel.

I'd not worry too much about RS484 on the SBC, a $25 cable is often cheaper than settling for an under-performing board, especially since there are a LOT of things you can do in parallel with controlling if you've got gPhoto on there! =)
