I want to develop small electronics device that interfaces with Camera based scanner (please google cam scanner) which has USB port to interface normally with PC USB port. The main issue with such scanners is it requires Laptop or PC to be connected to it with software to capture images. We are working on NGO project where field agents need to go to villages to capture many documents but in rural areas in India, electricity is not available for many hours (6-8 hrs) during day therefore scanner with PC/Laptop is not a viable option. Secondly carrying laptop/desktop will be hassle.
Therefore we want to design small device which can have good size battery which can last for 6-8 hrs. It should be enough to power USB based cam scanner, we can choose suitable model which draws less power from the USB port.
Functionality:
1. Device will connect to scanner on standard USB port
2. Device will have operating buttons which will take image of object under the scanner (Zoom, Snap, Delete, Browse)
3. Device will have small 3-4" LCD screen to show the preview image from the scanner and also image when browsed using control panel.
4. Captured images will be stored in built in storage or can have MicroSD card (2-16 GB storage)
5. Once field agent returns to office in the city, he/she can download the images to PC via MicroSD card reader or acting like USB mass storage.
6. This is NGO project so budget is tight (device cost)
7. We are looking for prototype, design specs, build in program to perform above tasks.
8. We are only end user and have no experience in this field so we can't provide any technical guidance. It is expected that selected partner has all the skills (hardware, writing device drivers, interfacing with USB etc). We can provide sample cam scanner for testing/development.
