I've compiled this step-by-step guide with references as I had trouble finding a similar resource online. Living in Toronto, the 2.4GHz WiFi band is over saturated and my best wireless throughput was roughly 16Mbps, now with 5GHz Wireless AC, I get an average of 700Mbps. I decided not to upgrade to the latest BIOS and to attempt the whitelist modifi…

Sump pump Monitor

Sump pump Monitor My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring. In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.
