Document to record notes about the hardware design of Decapod |
Computer System
User to use their own configuration if available.
If mobility is a use case, then we will have a recommended and minimum hardware configuration:
- Dual-Core CPU, Quad-core ideal for lots of remastering work
- 4GB RAM
- Capable of running Ubuntu 9.x
- 3 USB ports (can use a hub)
- About 10GB per book. Recommend 200GB HDD or a 32GB flash drive.
Camera Selection
Decapod will support cameras fully controllable by gPhoto2 and meet the Decapod minimum technical requirements.
- Decapod requirement: Capable of capturing at least in JPEG, 12MP
- http://www.gphoto.org/doc/remote/
- Currently we are using Canon G10 cameras.
- Use gphoto2 SVN version to test against cameras.
Wider selection of cameras to be tested.
Camera Mounts and Accessories
Rather than come up with a prescriptive list of tripods, we should give a short guide in making a proper selection based on our minimum requirements.
Tripod Head Requirements:
- 3/8" male head plate thread size (for supports support of Manfrotto 131DD double-head bar)Capable
Tripod Legs Requirements:
- 5 lb. load capacity (capable of holding 2 cameras simultaneously (weight varies depending on selection of camera models)
- Tripod plate thread size should match the tripod thread size of the tripod head selected (i.e. if tripod head has a 1/4" tripod thread, then the tripod legs must be 1/4" too).
- Reasonably compact (~20") to fit into briefcase, large bag, etc.
Double Camera Mount
Since the Manfrotto 131DD is the mounting bar we are using for the cameras, this restricts the choice of tripods to those with 3/8" threads.
...
*Note the above tripod legs have 3/8" tripod head mount thread size.
ATRC's Selection
- Manfrotto 131DD double head arm
- Manfrotto 486 tripod head with 3/8" mounts
- Manfrotto 190XDB
Other Double Camera Mounts (not recommended)
