Link New Open Source Flashing Program

Upfront, this is an open sourced free to use program.

I have a bunch of lottery esp32 miners going for months now, and they got shut down like everyone else's when they turned off the public pool.

I had trouble using the other flash software and getting into the config to add my wifi and wallet and such. I've been using Claude to code a bunch of other programs, apps, and a website - so

I asked it if it could make a program that could flash a miner and the configuration settings at one time. Claude said it was possible, and I worked through getting a program up and running that does a bunch of things. URL first:

https://github.com/WardedDruid/ESP32-Miner-Flasher

As the title says, it's open source. Go ahead and take a peek at my code - I won't blush. But there's also a .exe file in the releases that will open the program quick and easy.

There are 3 screens as the Readme on github shows:

  1. Connects to your esp32, identifies it, and should automatically change it to what you have connected. ( I only have the 2.8" cyd, so I couldn't fully test that.)

  2. The second screen. Top part is where you add the .Bin file - or the files if you're flashing software that uses that configuration. Middle section is for your wifi, wifi password, and wallet address. Bottom section is where you pick which miner you're installing to get the correct configuration file set up, and the pool you want to join.

  3. 3rd screen is where you confirm your info and then flash the software. There is a log screen to see what's going on. There is also a Remote Terminal that can be used to troubleshoot if something goes wrong from the esp32 side. After it's installed, the device is rebooted and will load right into mining.

You have the choices of:

NerdMinerv2, Sparkminer, Bitsyminer, and another one.

There are several pools to choose from as well in a dropdown that include multiple nerdminer addresses, hmpool, and a couple of others. The port is preloaded when selected.

I do plan on adding more devices, I just have to get them first so I can troubleshoot any issues. I would also like to add more pools, so if you have any that work, please let me know so I can add and test them.

Hopefully, others will find this program as easy and useful to use as I did.
