-As you can see from the flowchart above, most of the commercial pumps currently available are not compatible with OpenAPS; only a small selection of older Medtronic pumps are compatible.  For those pumps which are not compatible, we suggest the advocacy option of calling the pump manufacturer and informing them of the need for availability of pumps for DIY closed looping systems.  Thus far, there has been not been a receptive pump company to these requests.  Omnipod, Animas, T-Slim, and newer Medtronic pumps are still not compatible.

 #### Notes about deprecated hardware setups
 
-If you have looked at the docs before, you may remember seeing Carelink sticks and/or Raspberry Pi's as a more prominent recommendation. The community has generally moved away from Carelink sticks (because of poor range and other errors) as part of reliable rig use. The community has also moved toward using Edison-based rig setups due to the smaller size and lesser cost of these setups overall compared to the Pi rigs. The [Pi instructions still work and still exist](https://github.com/openaps/docs/blob/master/docs/docs/walkthrough/phase-0/hardware/raspberry-pi.md); however as of March 12, 2017, they are no longer the top recommended setup option. The community recommends following the documentation for buildling a rig based on the Edison and Explorer Board (which has a built-in radio stick to further reduce size, increase portability, and increase reliable looping range).
