NerdMiner V2 78KH/s T-Display S3 Bitcoin Solo Lottery Miner User Manual

1. Product Overview

The NerdMiner V2 T-Display S3 is a compact, open-source hardware device designed to allow users to participate in Bitcoin solo mining. This device aims to provide a practical learning experience about cryptocurrency mining while serving as an aesthetic desktop accessory. It operates with low power consumption, typically around 1 watt, making it an energy-efficient option for those interested in the mechanics of Bitcoin mining.

The device comes with the latest mining software (firmware version 1.6.3) pre-installed, simplifying the setup process. Users only need to connect it to a power source via USB-C, establish a Wi-Fi connection, and input their Bitcoin wallet address to begin operation.

While the probability of successfully mining a Bitcoin block is extremely low, the device offers the theoretical chance to win the current block reward, which is 6.25 BTC. Each unit is tested to achieve a hash rate of at least 78 KH/s and includes a small heat sink for thermal management.

3. Setup Guide

Follow these steps to set up your NerdMiner V2 and begin mining:

1. Power Connection: Connect the USB-C cable to the NerdMiner and then to a power source. The device will power on and display a QR code on its screen.
2. Wi-Fi Configuration:
   • Use your smartphone to scan the QR code displayed on the NerdMiner's screen. This will automatically connect your phone to the NerdMiner's Wi-Fi Access Point (AP). The default AP name is typically "NerdMinerAP".
   • Once connected, your phone's browser should automatically open the NerdMiner's setup page. If it does not, open a web browser and navigate to the IP address displayed on the NerdMiner's screen (e.g., 192.168.4.1).
   • On the setup page, click the "Configure Wifi" button.
   • Select your desired Wi-Fi network (SSID) from the list and enter its password in the "Password" field.
3. Bitcoin Wallet Address: Paste your Bitcoin (BTC) wallet address into the "Your BTC Addresses" field. If you do not have a Bitcoin wallet, you can register for one through services like Coinbase or other reputable Bitcoin wallet providers.
4. Time Zone Offset: Enter your UTC time zone offset. You can find a list of UTC offsets on Wikipedia's List of UTC offsets.
5. Save Settings: Press the "Save" button to store your configuration.
6. Restart and Mine: After approximately 30 seconds, the NerdMiner will automatically restart, connect to your configured Wi-Fi network, and begin the mining process.

Tip: To check the mining status at any time, open a web browser on a device connected to the same network as the NerdMiner and enter the NerdMiner's IP address.
