nerdminer_v2's Introduction

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 or any supported boards (check Build tutorial 👇)

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:

Get a TTGO T-display S3 or any other supported board
Go to NM2 flasher online: https://flasher.bitronics.store/ (recommend via Google Chrome incognito mode)

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.

Get a TTGO T-display S3 or any supported board
Download this repository
Go to ESPtool online: https://espressif.github.io/esptool-js/
Load the firmware with the binary from one of the sub-folders of bin corresponding to your board.
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

Online ESP Tool 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.
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

Connect to NerdMinerAP
- AP: NerdMinerAP
- PASS: MineYourCoins
Set up your Wifi Network
Add your BTC address
Change the password if needed
- If you are using public-pool.io and you want to set a custom name to your worker you can append a string with format .yourworkername to the address

SD card (if available)

Format a SD card using Fat32.
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,
  "PoolPassword": "x",
  "BtcWallet": "walletID",  
  "Timezone": 2,  
  "SaveStats": false  
}

Insert the SD card.
Hold down the "reset configurations" button as described below to reset the configurations and/or boot without settings in your nvmemory.
Power down to remove the SD card. It is not needed for mining.

nerdminer_v2's Issues

What is "normal" in time or amount of 16bit shares to get a 32bit share?

After 12 hours I have many 16bit shares, but still 0 32bit shares. What is likely normal to get a 32bit share of the amount of 16bit shares, or in time?
I get a feeling that the issue about parsing JSON, mentioned here, could be a problem why it doesn't get 32bit shares? Or am I wrong?

Not hashing

Hi! the templates keep running up, but there the shares and hashes keep at 0. Tried different power sources, usb cables and system resets. The receive address is correct. Have run it all day, but the hashing is still at 0. Anything else I could test?

Hash rate si blocca

L hash rate del nerd miner si blocca dopo un po' di ore e rimane a 0...va spento e riacceso perché riparta

other TTGO esp32 display

Does this also works with the 1.14 inch version instead of 1.9 inch display?

I tried but I got no image on display after flashing firmware.

Testing Results Thread: Release v1.4

I have upgraded all 3 of my nerdminers to release v1.4. (firmware bin only, as that was the only file updated).

I have one miner pointed to each of the following pools:

CK pool
braiins pool
zSolo pool

All three pools / miners were relatively stable prior to the upgrade. They would reset maybe every 24hrs +/-.

Now I am seeing the braiins Nerdminer rebooting itself every 8-10mins approx.

The other two miners appear to work fine so far. I will continue to run them to check stability.

New Feature : PWM Fan controlled by CPU Temperature

Love this project, and my little contribution is following

I've just quick and dirty created little PCB to be able to fit into T-Display-S3 as is

@BitMaker-hub Once I got it, I'll do a PR to implement this in code (and show CPU Temp on display), but if you want to add this feature before, of course you can :-)

These boards are untested but should works without any issue

R1 10K 0805
D1 1N4148
Q1 BSS138 SOT-23

You can order 3 boards (RAW PCB) for less than $2 shipping included at OSHPARK

Have fun

All metrics stay 0 (except online time)

What to do when
Bloc templates and 16bits shares and hashes stay on 0?
Already did a reboot.
Online time seems to work.

Rotation screen 180°

Hello somebody know how to make 180° screen rotation to use connection link on the left ?

Question about user id

Hey everyone, just a small question, can I use multiple devices with same user id (btc address) on the same pool? For example a NerdMiner and my old laptop, can they both use same btc address?

battery ?

hi,
since the ESP allows it. i plugged a battery on it.

i used one like the one on the photo on another ESP for another project ( the very good PoS ).

the idea is sometimes, for show or demo purposes or for fun on a desk to have the miner working without any wire. looks nicer and .. mysterious !
not for a long time but an hour or 2 would be nice.

the ESP is 3,7v so it could work on the 3.4v ... and it .. almot does.
when unplugged with the battery in it it goes on mining allright i think. but the screen stays black. you recover it when plugging again and see that the process is still on and running. ( looks like it anyway)

so it is close.
what is it missing ? some mA ? or is there a hardware safety measure ?
Could some code arrange that ? : test if battery on and make it work at a "slower" hashrate for example ?
or add a little electronic ? ( i saw an addon with a resistor to be able to tune the vent speed...)

It looks to me like a nice possible upgrade
i go from afar but i am quite willing to help work on it if you and/or other people think it is interesting.

but you haven't proposed or spoken about it, i suppose there is a good reason for that...

this is more a proposal with an issue than a real issue though. let me know if this should be posted elsewhere

Chmeulblu

Not an issue a question

Not an issue, but a question. Don't know where else to place it:

Can someone explain this that is in the readme? What does it mean it is not seen by the mining pools?

IMPORTANT Miner is not seen by pools due to its low share difficulty. You can check miner work seeing logs via UART or mainly setting up your own pool with a low difficulty rate as 1e-9

Can someone explain if there will come a mining pool just for nerdminers and why that would be better?

Installation help

hey how does one flash the firmware, or compile first and then flash the firmware I guess. Is there a blogpost or tutorial beyond "Load the firmware with the binaries from the src/bin folder.
Plug your board and select each file from src/bin with its address"
Cause thats where I am stuck. How do I load the firmware from either the src folder or bin folder. Or from both folders?

NerdMiner crashes

My NerdMiner crashes quite often. The longest runtime I have seen so far was a bit more than an hour. But it could also happen after a few minutes. This is what I see on the serial console.

No hash rate update on pool statistic

Hello,

I just started running nerd miner, it is a great project.
I have try get BTC address from my trezor and put in a config. firstly i run with ckpool for 2 hours and when I check on the address https://solo.ckpool.org/users/MYBTCADDRESS and it show the page not found then I decided to reset the config and try with zsolo pool and it was run for 10 hours but still no hash rate show up on the page https://zsolo.bid/en/user/btc?address=MYBTCADDRESS

Not sure this is normal or a bug on the miner.

Support Raspberry PicoW

move to platform.io

platform.io will automatically download env and needed libraries, consider to move project on platform.io

Not showing on Pool Sites

I tried ckpool and zsolo and it doesn't show it's hasing but it does show it's working on the screen at 20+KH/s

I reloaded the new bin files today as well.

Error: CryptoJS is not defined

Hello,

When trying to flash the firmware, I am getting the message: "Error: CryptoJS is not defined" and the firmware is not flashed.

Any thoughts on how to solve this?

Question: How to view worker after connecting to Braiins Pool?

Hi BitMaker,

Is there a way to view my miner (via Braiins Dashboard on web/mobile app) after I connect to the Braiins slush pool?

Thank you.

Suggestion: Add debug screen

Would be nice if there is a debug screen we can access using button press so that if anything isn't working correctly we can check it for notifications/cause. This way we can report errors easier.

The debug screen would only keep the most recent 5 notifications and all older notifications will be pruned/removed. This would prevent log bloat/overfill.

Error during flashing ESP32S3

Hello !

Thank you for this amanzing little miner and all your work.

I have a problem : when I load the firmware with the binaries from the src/bin folder, i have the following error :

This is weird because the miner seems to work perfectly.

How can I verify if there are something wrong ?

Does the miner really work?

I have a own BTC Node and setup a pool on it with the mining diff 0.00001.

The Nerdminer is not able to find share with this diff. I find that a bit strange.
Now I tried a CPU miner on my PC that has only one thread (11-18 KH/s) and I find 5-10 shares per second with it. My NerdMiner has 21 KH/s.

Unable to change SSID from confiiguration webapp after initial configuration

I apologize as I am a bit new to this platform and still working through some of the tooling involved, but I am pausing here to make a report that might help others with testing. I have successfully connected to a pool and started mining using pool solo.ckpool.org. Great work NerdMiner_V2 team.

I ran into this issue trying to determine what was going on when there was no handshake happening with the upstream pool and needed to change the configuration.

For a configured NerdMiner, disabling the specified access point helps put the NerdMiner into NerdMinerAP configuration mode after some time. I read else where holding the top button 5 seconds might do the trick, but disabling the access point helped in my situation when button access was an issue.
Connect to the webapp at http://192.168.4.1 and change the ssid and password values and submit. NOTE: While the ssid and password are the only values offered from the webapp and the webapp is the only presentation relevant to this issue, for fun I did try variations using curl to get at the configuration values i.e.

curl --location --request POST 'http://192.168.4.1/wifisave' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 's=myssid' \
--data-urlencode 'p=myssidPassWord' \
--data-urlencode 'Poolurl=btc.zsolo.bid ' \
--data-urlencode 'Poolport=6057' \
--data-urlencode 'btcAddress=bcxyzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz6d'

The result is the ssid is not changed and the NerdMiner connects to the previously configured ssid.
The only way I found to change the mining configuration is erase the flash AND reflash the firmware.

I hooked up the serial console and here is what I observed when using the NerdMinerAP configuration mode and attempting to change the ssid from the webapp a couple times:

Support for other ESP32-S3 boards

I do own one ESP32-S3 Box and one WT32-SC01 Plus. Both boards are S3 compatible, but do have other display resolutions. It would be nice, to support also other boards for this.

If wanted, I could create PRs for that.

lost WLAN connection after same hours

Hi, after about 2-4 hours, the miner is currently leaving my WLAN. No new blocks are then requested and the hash rate goes to zero. Everything else seems to continue to work. At the moment I can't see why it should be. Version is the latest 1.4
Edit: now i have a uptime from 13h, I hope he lasts a while longer.

Possible to run on other ESP32 versions

Hi.
Is this possible to be run in other versions of ESP32 such as ESP32 DevKitC-32E, which is based in the following iiem:
https://www.espressif.com/en/products/devkits/esp32-devkitc
and based on this part:
https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32e_esp32-wroom-32ue_datasheet_en.pdf

Buttons without function

the miner works so far. If USB-C is on the right, the top button is totally reset. It works. I couldn't understand the function of turning the display with a double click and display off. Version 1.4

Suggestion: Uptime

Is it possible to change the Uptime in "days - hours - minutes" if it reaches above 24h or in general?

Zsolo pool doesn't works

My 3 devices did go to zero 9 hours ago (zsolo and port 6056).
I tried to reset or reboot my router with no luck. Change to ckpool fix the problem.
I see that in zsolo web there isn't mention to the very low hash port (dissapear) and only normal diff (>500)
Using 6057 doesn't works anymore.
Back to ckpool before nerdpool will go online. ;)

Turn off display

Instead of having the display always on, it would be nice if there was an option to have it off by default and switch it on for some seconds when a button is pressed.

If AutoConnect: FAILS during startup a wifi Acces Point is created

When wifi is configured but detecting wifi on startup fails, autoconnect hangs and start a new AP.
At screen appears 0.00 Hashrate

Zero Hash Rate

After running for a few hours, the hash rate goes to zero. That issues usually takes 24 hours to happen.

Completed setup but not hashing

I was able to configure the miner but once it went through the setup, the main screen just shows the count for how long the device has been on. All other items being tracked on the screen are at zero.

Wifi failure

Hi! Cool project!
When I connect to wifi it reboots multiple time and it connects succesfully to the wifi but ends up disconnected and back in AP mode. When I login wifimanager says authentication failure.

Tried to find solutions in wifimanager github but no real success for a solution, although connection issues seem to be prevalent in wifimanager:
tzapu/WiFiManager#1067

Cannot set BTC address

I do not see a possibility to configure the BTC address after a reset.

Password incorrect (fixed)

I had a device that I flashed successfully, but when I tried connecting to the access point it would not connect and show a 'password incorrect' message on my phone. Also the QR did not work. Tried flashing multiple times but the problem persisted. 3 other devices did not have this issue at all.

The solution was to do an "Erase flash" first in the ESP Tool flasher, and then load the firmware again. After that the issue was fixed. Putting it here for others, as a pull request for one line in the readme seemed a bit of overkill. ;)

cheers,
Yafsec

Idea: Adding OTA updates. (low-prio)

I've seen a few people on twitter and telegram, some of whom have 4+ nerdminers.
Wouldn't an OTA feature be useful specifically for these people?

Question: Is it possible to connect to lincoin.com mining pool?

@econoalchemist has a pool:

[Taken from recent Spotify pod256 pod cast description]

Pick any Lincoin URL:

a)  stratum+tcp://NA.lincoin.com:3333

b)  stratum+tcp://EU.lincoin.com:3333

c) stratum+tcp://LatAm.lincoin.com:3333

d) stratum+tcp://CIS.lincoin.com:3333

e) stratum+tcp://Asia.lincoin.com:3333

f) stratum+tcp://OC.lincoin.com:3333

g) stratum+tcp://Africa.lincoin.com:3333

Then use "pod256.YourAlias" as the worker name.

I tried to use 'NA.lincoin.com' and port '3333' but 'shares' counter on NerdMinder does not increase. hash rate stays at 0.00.

Is any special setup required in order to connect to a mining pool or does the mining pool need to support a specific connection?

Buttons not working

Using firmware '0x10000_firmware.bin', the only button option that works for me is:
Hold 5 seconds > top right button to reset the configurations and reboot your NerdMiner.

Device: LilyGO TTGO T-Display-S3 ESP32-S3 - met 1.9 inch TFT Display

TOP BUTTON

~~One click > change screen.~~
Hold 5 seconds > top right button to reset the configurations and reboot your NerdMiner.
~~Hold and power up > enter configuration mode and edit current config via Wifi. You could change your settings or verify them.~~

BOTTOM BUTTON

~~One Click > turn the screen off and on again~~
~~Double click > change orientation (default is USB-C to the right)~~

Battery use - need specials specs ?

HI,
i see there is another firmware that deals with Battery. thanks.
i tried it right away and get the same behavior as before however :

If a battery is plugged in and you disconnect the USB power source to use the miner on the go ...the screen goes black.
when you plug it in again to an usb power source, after some time, you see that it has gone on mining during the "black out" . time, shares, Millions hashes .. have continued and gone up. Great.
so it is working and may be that shouldn't be an issue ?

Is my 3.7 v 1000mAh battery too weak somehow ? it fits the 3.4v ESP need ...
can you recommend some or post the one you used that obviously works fine including the display and can fit within the miner's box ?

Thanks.
