My specialty is creating consumer electronics and web/mobile applications that seamlessly integrate. Have quite a lot of experience with this. Check out my blog, it's in my profile, wrote a popular article here on HN (it's also on my blog) on how to and the tools to use when designing, prototyping, and manufacturing consumer electronics. If you have further questions feel free to email me, done it enough I can usually figure out what you'll need to do pretty fast.
