I think it's fine if you're willing to accept the risk. My 7 year old has been a type 1 diabetic since he was 19 months old. Despite being a software developer and being tech savvy, I'm unwilling to use a DIY solution like this on him. If I had type 1 diabetes, I'd be more likely to try it.

Having said that, we still benefit from these efforts. I run Nightscout on Heroku so I can monitor his blood glucose levels remotely while he's in school. This is less necessary now that he's using a Dexcom CGM (they provide their own glucose sharing app.) His previous pump/CGM was made by Medtronic - their sharing functionality is/was atrocious and Nightscout's bridge made it serviceable. We also have a few tablets around the house so we can keep an eye on it throughout the day and night.
