Hi,
I am an Electronics and computer science engineer, I have experience working with various prototyping boards, Raspberry Pi, Arduino, mbed (ARM proto board)... as well as developing custom PCBs, you can find some of my projects on my portfolio.
Raspberry pi in particular was used in numerous of my projects in the prototyping stage and as proof of concept, some also prefer to use it to avoid having to certify their products. I believe I can accomplish your project from your description.
I noticed that your project is a bit old, and I'm not sure if you're still interested or if you've hired anyone.
If you're still interested though, let me know and we can have a thorough discussion about the details. Thanks
The price is merely a placeholder at this stage
I pride myself on ensuring that the customer is satisfied with the quality of the work and strive to sustain good communication and complete the project
Looking forward to working with you.
Regards,
Nabil
