Gadget Review: SMT1500i UPS + Linux Instructions

I never get power cuts. But, we've had two in the last week. They've both been fixed quickly, but it takes an age for my cable modem to reboot - and then an age for my smarthome to reconnect to the WiFi. So it was time to invest in an Uninterruptible Power Supply (UPS).

My friend Paul Curry recommended the APC
