Trying to find somebody to design a hardware project

Former Member

Guys,

 

I am really sorry if this question comes off topic or is not in it's place exactly.

 

I played a lot with Arduino board and Raspberry PI and found them very interesting as a base for my future commercial project.

So, my question is - could you, please help me find a good hardware designer who can help me with building the schematics, then layout of the PCB. Then after the prototypes are live and working I will write the software for this project. It will be based on Raspberry PI with some modifications and additions to it.

 

Your feedback will be greatly appreciated.

 

Sorry once again for bothering you,

Thanks,

Evgeny

  • It might help if you can provide a little bit of information about what you are trying to achieve.

    Most engineers have a particular field of expertise on which they can offer advice or support.

    Well,

     

    The design should follow approximately these lines:

     

    1. Raspberry Pi board without the composite video which I don't need.

    2. Mini printer - interfaced by TTL RS232 or similar serial protocol.

    3. LCD connected - also serially.

    4. Keyboard - I2C connected.

    5. crypto card - TTL RS232 or similar

     

    Of course, the interfaces could be changed but the idea is to use Raspberry only as software intensive board and to control all hardware by their own control chips.

     

    Please, comment on this and maybe you could suggest some other solutions too.

     

    Thanks

    The RPi is a very poor platform for this kind of project. The hardware design is not open source and some of the key components are very hard to get in less than 10k+ quantities. This means that it is very hard to make a modified RPi with different interfaces so you are stuck with using an RPi with an add on board. If the numbers are small or there is a compelling reason to use the RPi this may be acceptable.

    The BeagleBone Black and some of the Atmel ARM dev boards (amongst others) are designed to be cloned or used as a starting point for a new product.

     

    The first question any hardware designer will ask you (more or less nicely and directly) is "Can you afford to pay for this kind of work"  so you need to have a good idea of the economics of your project.

    Thank you, I will look into Beaglebone Black also, thanks.
