Raspberry Pi Tablet Specification
Raspberry Pi Tablet and Video Production Studio- make a fully functional computer tablet with phone from a touch screen, a Raspberry Pi, and a 3D printed case printed with your own printer, and a circuit board for the camera and charger. You will also make your own battery pack from the popular 18650 lithium ion cells. The special purpose of this tablet is documentation: taking video and picture instructionals. Thus the Tablet comes with interchangeable lens, wireless mike, and a tripod, and we will be building an entire open source sound/video studio around it - including augmented reality instructional creation.
Spec for January 2020
The ideal outcome for the product that we offer in the first workshop would be this. This would be super exciting, and definitely marketable, as it includes the video production aspect:
- Touchscreen Tablet with camera. Can you design that so we can retrofit various lens on it, such as telephoto for depth of field and micro/microscope for closeups? I know that the camera microscope exists and it appears open source as it is listed at OSHWA.
- Case should have a mount for a tripod. The tripod can be 3D printed. We're talking about using this for the open source film studio (basic even 480 HD is fine for what we need). The studio and whole design is collaborative video editing and production, for which we are developing a protocol.
- Wireless mike - can you integrate into this? This would give it tremendous value for producing quality video (sound is more important that video)
- 24-48 hour battery life for overnight timelapses. this can be done by a linear pack of 18650 cells that goes inside the case without fattening it up. This is important, as we do all-day timelapses in our event - and sometimes batteries run out and it destroys the time lapse. We want to eliminate battery life from the equation.
- And now the phone - the use case is the Developer's Multipurpose Phablet - targeted at DIY diehards like me (there are plenty of them) who want to use their own equipment. The biggest use case is that this turns into a circular economy product with lifetime design - you can keep modifying and upgrading the system. The Phablet could also be used to start print jobs on the 3D printer - they have a wireless SD card, so make sure how you design this it is compatible with wireless SD. For the phone - I think the easiest way would be to add a second Pi Zero to this system, with SIM card, that handles just the phone aspect. We want to make sure we have capacity for wireless headphones. We already have open source wired headphones by Chris from our team - which we can convert to wireless.
- Freedom. The absolute requirement is open source CC-BY-SA 4.0 International (OSHWA and OSI compliant) open source license which provides freedom for others to build this and sell this if they like. That is the supercooperator business model that we're developing, and it will become larger than Amazon probably within 1-2 decades. But we can't f around on this point - without open source distributive economics this thing will get coopted like open source software got coopted. We are committed to free hardware - free as in freedom, not free beer.
- Low cost - Keep the cost down. Possibly make 2 versions, a high end and a low end. Ideally, the 2 versions are modules: say low cost without the phone, but the phone is a module that can be used if one likes.
- Modular - Interchangeable with Beagle Bone for the main board. Design it for mountability of either Beagle Bone or Raspberry Pi.
- Capable of running FreeCAD
- Open source operating system. (Dual Boot Android/Linux?)
- PORTS An attached/built in (powered?) usb 3.0 type a or c hub, a display out port/ports, a display in port, audio out, and audio in port. This would allow for the attachment of modules annd other accesories without tons of adapters/dongles
OSE would like to basically have a bunch of these in the workshop (without the phone part at least), and in the film studio we plan to build here next year - as our main tool.
This film equipment integrates with drones for aerial photography, and open source sliders and camera stabilizers - but that's for later. All we have is this for Pi tablets prior art.
