Build a Duino-coin mining rig using NodeMCU boards

Building a Mining Rig with NodeMCUs

In this video, the presenter demonstrates how to build a simple mining rig using eight NodeMCUs to mine DoInCoins. The presenter also shows how to upload the ESP8266 Arduino program to the NodeMCUs and 3D print a frame to keep them organized.

Uploading the ESP8266 Arduino Program

• To start building the mining rig, upload the ESP8266 Arduino program to each of the eight NodeMCUs.

• Change four things in the code: Wi-Fi SSID, Wi-Fi password, DUCO username, and board identifier name.

• Hit upload for each board and change only the board identifier name for each one.

3D Printing a Frame for Organization

• Design a simple frame in Fusion 360 that can hold four NodeMCUs on top and four on bottom.

• Export as an STL file and use Ultimaker Cura slicing software with infill setting of 20 and layer height of 0.2 mm.

• Print out the design which takes approximately five hours.

• Assemble the frame by placing each NodeMCU into its designated slot.

Checking Status on Web Wallet

• After turning on all eight boards, wait a few minutes for them to connect to the server.

• Open up your web wallet account and check on your boots' status.

Power Consumption Calculations

In this section, the speaker discusses the power consumption of eight nodems and provides calculations based on values obtained from the internet.

Power Consumption Calculation

• Eight nodems running for an entire day will consume around 26 to 27 watts.

• The calculations are based on values obtained from the internet.
