Hello, I have recently completed a project integrating real-time functions and low-cost LCD displays. I have also developed voice-capable telecommunications devices (use MP3 files to guide the caller through the processes). I can design with batteries, AC/DC, DC/DC power. USB interfacing is also possible. This seems like an interesting project. I can also provide fully-assembled and tested boards, but at the additional cost for parts and assembly, and the cost of firmware would be extra (I normally only provide test software ti make sure the hardware works). I do provide one-year warranty and one free upgrade to the initial boards to make them production ready, and also one free upgrade during the lifetime of the product. I also can provide documentation support should you decide to get CE certification and such. Let me know if I can be of help. Best regards, Stuart Borden.
