I’ve learned a lot from my personal use of OpenAPS over the last four and a half years. I’ve also learned a lot through helping, and observing, other people’s journeys in using DIY and more recently, also commercial versions, of artificial pancreas systems. I’ve spent a lot of time writing tips, tricks, and suggestions for people over the years. Although this content has been fully available online for years on my blog (www.DIYPS.org), I recently realized that most people thinking about looping in various forms don’t have a single place to get a comprehensive picture about their technology options, the lessons the community has learned about the learning curve of switching from manual to automated insulin delivery, and a straightforward, plain-language explanation to guide them in making their choices.
