A closed-loop system can only be as good as the CGM that’s feeding it. Keeping that CGM accurate is essential! I’m currently running an experiment where I’m using a Dexcom G5 sensor and a Libre sensor concurrently to compare the behaviour and results. Mostly they track fairly closely, although at first glance the Libre does …
“My friend’s kid has one of those.” Not an unusual reaction if I describe my closed-loop insulin system to someone without diabetes. They’ve heard about insulin pumps, and not unreasonably assume that they take a lot of the work away by automatically adjusting the insulin dose as required. Because that seems an obvious application of …
In my closed-loop pump system, the OpenAPS rig (a tiny Linux computer) communicates with the Medtronic Veo 554 pump every few minutes via radio. This works great, but it does put extra load on the pump’s AAA battery. So the batteries don’t last as long as in a non-looping pump. These AAA batteries are smaller …
Insulin pumps are life-sustaining devices that we live with 24 hours a day, so we become quite invested in them. We all live different lives, and our needs (and tastes) in insulin pumps vary. With this week’s announcement that Animas has shut down in the US/Canada, there are obvious clouds on the horizon for Australian …
Well a lot has been going on recently! Looping! I have been running my insulin through a closed-loop pump system for several weeks now, and it’s running well. My system is using a Medtronic Veo pump, an OpenAPS Edison rig, and my existing JARVIS CGM. The OpenAPS software can be configured in many ways, but by …
You may know the story behind the name of my CGM (continuous glucose monitor): JARVIS. Now I’m building another machine to be part of my diabetes network, and because it will have connections across WiFi and Bluetooth networks it really helps if it has its own network name. This machine is an OpenAPS rig: a …
