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
- 3D BOX here
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.
- Get a TTGO T-display S3
- Download this repository
- Go to ESPtool online: https://espressif.github.io/esptool-js/
- Load the firmware with the binaries from the src/bin folder.
- Plug your board and select each file from src/bin with its address
Build troubleshooting
- Online ESPtool works with chrome, chromium, brave
- ESPtool recommendations: use 115200bps
- 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
- 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.
NerdMiner configuration
After programming, you will only need to setup your Wifi and BTC address.
- Connect to NerdMinerAP
- AP: NerdMinerAP
- PASS: MineYourCoins
- Setup your Wifi Network
- 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 |
Buttons
With the USB-C port to the right:
- Hold top right button and power up to enter configuration mode and edit current config via Wifi.
- During normal operation hold 5 seconds top right button to reset the configurations and reboot your NerdMiner.
- Click the bottom button once to turn the screen off and on again
- Double click to change the orientation (default is USB-C to the right)
