**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.

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

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/

#### 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
1. Setup your Wifi Network
1. Add your BTCaddress
**If you need to reboot your currentConfig**, hold right top button during 5 seconds and config will be deleted.

## Developers
### Project guidelines
- Current project was addapted to work with PlatformIO
- Current project works with ESP32-S3 but any ESP32 can be used.
- Partition squeme should be build as huge app
- All libraries needed shown on platform.ini
### On process
- [x] Move project to platformIO
- [x] Bug rectangle on screen when 1milion shares
- [x] Bug memory leaks
- [x] Bug Reboots when received JSON contains some null values
- [ ] Improve hashrate using Blockstream Jade miner code
- [ ] Add blockHeight to screen
- [ ] Add new screen with global mining stats
- [ ] Add support to control BM1397
Enjoy
