- This was installed in mid 2015 as part of the ePingER project (see ePinger Project at SLAC). It has run flawlessly without manual intervention for over 3 years, automatically recovering from power outages etc. The OS failed a security scan. Rather than upgrade etc., since it has served its time, we decided to decommission it and focus more on the PingER/Android project. Bebo I have the Raspberry Pi and SD card, if you want it.
