# 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.
|
|
|
|
|
|
Original project https://github.com/valerio-vaccaro/HAN
|
|
|
|
|
|
|
|
## Requirements
|
|
- TTGO T-Display S3 or any supported boards (check Build tutorial 👇)
|
|
- 3D BOX [here](3d_files/)
|
|
|
|
### Project description
|
|
**ESP32 implementing Stratum protocol** to mine on solo pool. Pool can be changed but originally works with Public-pool.io (where Nerdminers are supported).
|
|
|
|
This project was initialy developed using ESP32-S3, but currently support other boards. It uses WifiManager to modify miner settings and save them to SPIFF.
|
|
The microMiner comes with several screens to monitor it's working procedure and also to show you network mining stats.
|
|
Currently includes:
|
|
- NerdMiner Screen > Mining data of Nerdminer
|
|
- ClockMiner Screen > Fashion style clock miner
|
|
- GlobalStats Screen > Global minery stats and relevant data
|
|
|
|
This miner is multicore and multithreads, both cores are used to mine and several threads are used to implementing stratum work and wifi stuff.
|
|
Every time an stratum job notification is received miner update its current work to not create stale shares.
|
|
|
|
**IMPORTANT** Miner is not seen by all standard pools due to its low share difficulty. You can check miner work remotely using specific pools specified down or seeing logs via UART.
|
|
|
|
***Current project is still in developement and more features will be added***

### Flash firmware
|
|
#### microMiners Flashtool [Recommended]
|
|
Easyiest way to flash firmware. Build your own miner using the folowing firwmare flash tool:
|
|
|
|
1. Get a TTGO T-display S3 or any other supported board
|
|
1. Go to NM2 flasher online: https://bitmaker-hub.github.io/diyflasher/
|
|
|
|
#### Standard tool
|
|
Create your own miner using the online firwmare flash tool **ESPtool** and one of the **binary files** that you will find in the ``bin`` folder.
|
|
If you want you can compile the entire project using Arduino, PlatformIO or Expressif IDF.
|
|
|
|
1. Get a TTGO T-display S3 or any supported board
|
|
1. Download this repository
|
|
1. Go to ESPtool online: https://espressif.github.io/esptool-js/
|
|
1. Load the firmware with the binary from one of the sub-folders of ``bin`` corresponding to your board.
|
|
1. Plug your board and select each file from the sub-folder (``.bin`` files).
|
|
|
|
### Update firmware
|
|
Update NerdMiner firmware following same flashing steps but only using the file 0x10000_firmware.bin.
|
|
|
|
#### 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
|
|
1. In extreme case you can "Erase all flash" on ESPtool to clean all current configuration before uploading firmware. There has been cases that experimented Wifi failures until this was made.
|
|
1. In case of ESP32-WROOM Boards, could be necessary to put your board on boot mode. Hold boot button, press reset button and then program.
|
|
|
|
## NerdMiner configuration
|
|
After programming, you will only need to setup your Wifi and BTC address.
|
|
Note: when BTC address of your selected wallet is not provided, mining will not be started.
|
|
|
|
#### Wifi Accesspoint
|
|
|
|
1. Connect to NerdMinerAP
|
|
- AP: NerdMinerAP
|
|
- PASS: MineYourCoins
|
|
1. Setup your Wifi Network
|
|
1. Add your BTCaddress
|
|
|
|
#### SD card (if available)
|
|
|
|
1. Format a SD card using Fat32.
|
|
1. Create a file named "config.json" in your card's root, containing the the following structure. Adjust the settings to your needs:
|
|
```
|
|
{
|
|
"SSID": "myWifiSSID",
|
|
"WifiPW": "myWifiPassword",
|
|
"PoolUrl": "public-pool.io",
|
|
"PoolPort": 21496,
|
|
"BtcWallet": "walletID",
|
|
"Timezone": 2,
|
|
"SaveStats": false
|
|
}
|
|
```
|
|
1. Insert the SD card.
|
|
1. Hold down the "reset configurations" button as described below to reset the configurations and/or boot without settings in your nvmemory.
|
|
1. Power down to remove the SD card. It is not needed for mining.
|
|
|
|
