Reading around, it's the controller software that is DIY, and it's grown to the point where a DIY device has been built to run the controller software. The sensor and pump/actuator are proprietary Medtronic devices, connected to the controller via wireless links. The DIY controller came about because Medtronic didn't secure their wireless traffic and the protocol was reverse egnineered. New units now come with a secured wireless link, but the existing units remain unsecured. Consequently the project is constrained by the number of unsecured units remaining in the field? Reading the project's website the FDA has been in touch with the project and so far the interaction has been constructive. The makers seem keen to have the safest system they can and the FDA seems to want to engage. I'd guess the project's future lies in being able to team up with someone who can provide ongoing access to sensors and actuators? Wishing them much success!

Near the end of the article: > A European team recently created an app for Android phones and cracked the code in a popular pump from Roche Holding AG So even if they don't find a partner, they'll probably find pumps they can use.

  A friend of mine "automated" his infusion pump (not diabetes) by 3D printing an arm and actuators attached to the physical buttons of the pump and controlling that remotely. Basically most actions consisted of automated sequences of button presses in the correct order. How feasible is this for an insulin pump? I know it adds bulk to a device that has to be worn constantly and inconspicuously but it may be a worthwhile trade if you can't find a compatible pump. As long as it can be controlled by the wearer's finger it should be possible to automate it with an "artificial finger".

  I'm currently using the AndroidAPS and it works great. Roche has said the warranty is off if you use the Combo pump for looping, but the maker of the other supported pumps DanaR and DanaRS said that looping is OK. Right now I'd recommend getting the newer DanaRS and a Dexcom G6 for the best possible support.
