Hello, Have a look at http://droidalyzer.com/tech.html . It is based on IOIO V1 but it does more or less what you would like.
It has a battery of only 400mA, thus you might want to have a more powerful one to have a battery life similar to the one of your mobile phone (we use 2000 mA) You might also want to make your own IOIO based on an IOIO OTG using this component https://www.sparkfun.com/products/11231 to charge your battery and obtain the necessary voltage out of a single cell battery. The Bluetooth connection between the IOIO and the mobile often drop. Always assume that connection might not work for an undefined period of time (what should you do then, ring an alarm?) . The mint case will for sure not be big enough for the IOIO, the battery and the Dexcom: you can design one fitting exactly your need and have it 3D printed (we use http://www.sculpteo.com/en/) Even though an interesting exercise for yourself, be extremely cautious about making any medical claim ... you are trying to build a medical device and those are rightly heavily regulated (FDA or similar organisation). Please note the disclaimer for the Droidalyzer and it is just an alcohol sensor not a medical device. So it looks like an interesting experience for you but for the large scale usage, I would wait the Dexcom to make an app connecting their sensor with the mobile. It seems that from a technology point of view all the things are there to make this. That would be one device less to carry / recharge.. and it will be a lot lighter. It might be worth checking their plan before investing too much time/money. Good luck, Ben On Friday, July 11, 2014 6:28:50 PM UTC+2, Jonathan Moore wrote: > > I am sure I am messing up the terminology here so please forgive me.
