Story

Demo of Crypto Miner

High Level Flow

I’m using the Arduino MKR1000 to post all the sensor data to the Raspberry Pi which saves the readings to a RethinkDB instance. I have an Alexa skill running on the AWS lambda service that Alexa will use to request data from the mining rigs. The skill sends a call to the Pi and it returns the latest readings or hash rates. The Pi also acts as a web server to deliver a dashboard with a web socket connection to keep the data streaming in.

Mining Rig Hardware

My mining rig consists of two water cooled 290x GPUs which are currently mining Ethereum. I have a temperature probe taped to the backplate of each of the graphics cards, one near the PSU inside the case, one on the exhaust of the radiator and one probe for room temperature. The probes are all wired directly to the same pin on the MKR1000 and use OneWire protocol.
