# NerdSoloMiner
**The NerdSoloMiner v2**

This is a **free and open source project** that let you try to reach a bitcoin block with a small piece of hardware. 

The main aim of this project is to let you **learn more about minery** and to have a beautiful piece of hardware in your desktop.

## Requirements
- TTGO T-Display S3
- 3D BOX [here](3d_files/)

### Project description
**ESP32 implementing Stratum protocol** to mine on solo pool. Pool can be changed but originally works with ckpool.

This project is using ESP32-S3, uses WifiManager to modify miner settings and save them to SPIFF. 

This miner is multicore and multithreads, each thread mine a different block template. After 1,000,000 trials the block in refreshed in order to avoid mining on old template.

***Current project is still in developement and more features will be added***

## Build Tutorial
### Hardware requirements
- TTGO T-Display S3 > Buy it on aliexpress or amazon
- 3D BOX

### Flash firmware
Create your own miner using the online tool **ESPtool** and the **binary files** that you will find in the src/bin folder.
If you want you can compile the entire project using Arduino, PlatformIO or Expressif IDF.

1. Get a TTGO T-display S3
1. Download this repository
1. Go to ESPtool online: https://espressif.github.io/esptool-js/
1. Load the firmware with the binaries from the src/bin folder.
1. Plug your board and select each file from src/bin with its address 

#### Build troubleshooting
1. Online ESPtool works with chrome, chromium, brave
1. ESPtool recommendations: use 115200bps
1. Build errors > If during firmware download upload stops, it's recommended to enter the board in boot mode. Unplug cable, hold right bottom button and then plug cable. Try programming

### NerdMiner configuration
After programming, you will only need to setup your Wifi and BTC address.

1. Connect to NerdMinerAP
    - AP:   NerdMinerAP
    - PASS: MineYourCoins
1. Setup your Wifi Network
1. Add your BTCaddress

Optional you can select other pool:

| Pool URL                 | Port | URL |
|---                       |---   |---  | 
| solo.ckpool.org          | 3333 | https://solo.ckpool.org/ |
| btc.zsolo.bid            | 6057 | https://zsolo.bid/en/btc-solo-mining-pool |
| eu.stratum.slushpool.com | 3333 | https://braiins.com/pool |

**If you need to reboot your currentConfig**, hold right top button during 5 seconds and config will be deleted.
