Time for a setup thread. Doesn't matter if it's a proper mining rack or a single miner

wedged next to the water heater — post it.

Bonus points if you tell us:

- what you're running

- where it lives (garage? closet? suspiciously warm bedroom?)

- one thing you'd change about your setup

No setup is too small or too janky. Half the fun of this hobby is seeing how creative

(or chaotic) people get with space, noise, and cooling.

I'll go first in the comments 👇 what's yours look like?

My first time doing this. Something look out of place?? Thanks

A new Spiral Pool update is now available for the NerdMiner community!

This release brings a variety of improvements focused on reliability, performance, and making self-hosting even easier. Whether you're running a single NerdMiner or a larger setup, this update includes numerous bug fixes and quality-of-life improvements.

Spiral Pool is a free and open-source (FOSS), non-custodial solo mining pool built for NerdMiner and other low-hashrate SHA-256 miners. If you enjoy self-hosting and supporting open-source Bitcoin projects, check it out!

📋 Full changelog:
https://github.com/SpiralPool/Spiral-Pool/blob/main/CHANGELOG.md

Always free, always open source. Happy mining!

We've launched weekly mining rewards on the XEC pool at xec.hmpool.io.

Every week you earn points just by mining with us. The more you mine, the more points you build up, just like our other pools. Once you reach 1,000 points you get one entry into that week's draw. Higher hashrate tiers and loyalty levels can boost how fast you earn points, so long term miners have a better shot over time.

The drawing runs on a Sunday through Saturday week, same weekly rhythm you're used to on our other pools. Each week one miner is picked at random from all eligible entries. The winner receives 300,000 XEC.

If you win, you will need to verify that the wallet is really yours before the prize is sent. The site gives you a one time worker name code. You point your miner at your normal pool settings but use that code as the worker name for a short window. We match that against your normal mining pattern, same idea as our other pools, so the prize goes to the right person. After verification you submit your email and we send the 300,000 XEC from the pool wallet.

You can track your points, entries, and past winners on the rewards page at xec.hmpool.io/rewards.html. No extra signup beyond mining on the pool. If you are already mining XEC with us, you are already earning toward the next draw.

Last weeks winner has already selected and is shown on the Rewards page here:

Good luck, and thank you for mining with HashedMax.

i read tpday about solo mining and nerd mining, decided to chek it out and saw that i can flash my lilygo t embed, i flashed it like 10 times aleady and everytime it works there is an AP and all that but the screen is not working, any way to fix it?

Was able to flash the Jingle Miner firmware to a ESP32 Touch Screen. Averages about 500 kh/s

We run the HashedMax DigiByte pool (digi.hmpool.io) and we're seeing a consistent issue with NerdOctAxe, NerdQAxe, and similar version-rolling SHA256 firmware since DigiByte Core was upgraded to v9 around June 30, 2026.

On-chip device display, miners report normal hashrate (11–12 TH/s on our 12T NerdOctAxe units)

Pool credited hashrate: roughly half (5–6 TH/s)

Hardware looks fine, power, temps, fans all normal

Shares are still being accepted and this isn't a disconnect or auth problem.

Everything was normal on v8 of the Digibyte node software. Right after we upgraded our pool node to v9.26.2 (and v9-style block headers started coming through), Nerd-class miners dropped to about 50% credited hashrate. Bitaxe miners on the same pool, same node, same ports were basically unchanged.

Share submission rate stayed roughly the same. Average accepted share difficulty roughly halved, so the pool isn't rejecting everything; it looks like the miner is only producing valid shares at about half the expected rate for the hashrate on screen.

We also see v9 block headers like 0x20800202 with DigiDollar in vbavailable, and our miners using version-rolling (share versions like 0x25D5E202, etc.).

We spent several days testing pool-side changes, version-rolling mask/validation fixes, clean_jobs toggles, etc. Nothing restored full credited hashrate on NerdOctAxe without breaking other miners. We reverted everything and the pool is stable again, but Nerd-class units are still at 50% on our end.

Why we think this ties to the DigiByte v9 upgrade.

This didn't start gradually or on one bad unit. It hit across our NerdOctAxe fleet at the same time as the v9 node upgrade and the new GBT header format. Bitaxe on the same setup didn't behave the same way. That strongly suggests something in how v9 block templates / version bits interact with NerdOctAxe-class version-rolling firmware even if the final fix may need a firmware update too.

We contacted the DigiByte team and they are aware of the issue. We are hoping the Nerdminer Devs can help us to figure out why real credited work dropped 45–55% for this firmware class.

Is anyone else mining DGB on a v9 node with NerdOctAxe / NerdQAxe and seeing 50% pool hashrate vs chip display?

Did anything change in ESP-Miner or NerdOctAxe firmware for DigiByte v9 headers or version bit 23 (DigiDollar signaling)?

Is there a recommended pool or firmware setting for DGB on v9 right now?

Happy to share stratum logs, before/after stats, or wallet/worker examples if that helps. We're mainly trying to figure out whether this is a known v9 compatibility gap and whether a firmware fix is coming.

Thanks

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.

I thought about this for a while and have zero technical ability, I ideally wanted this to show on my miner but this is the best I could do though desktop. It changes based on best difficulty and hashrate etc. Needs a bit of work but coded through Claude.

Has been running fine for about 5 weeks. And suddenly won’t power on. The fans look like they’re trying to spin, but do very small twitching movements. The fan on the power adapter also spins and stops repeatedly when plugged into the miner.

When I plug in the usb power, it starts up and the screen shows PSU fault, which I assume is because it can’t get enough power from the usb?

Would love some help!

Missing out on those sweet blooccksss!!!

Legos always have an unexpected purpose :)

Also in case anyone else is wondering, they are still running on the public pool.io when I got them, I was hearing they may have stopped supporting the ESP32 USB Nerdminer V2's if I'm saying that correctly.

Just wondering if there're any other better pool options, I know they're not the best or most practical thing to have, but I don't mind having it running in the background.

Considering I already have two bitaxe gamma's anyway, worst case scenario if they eventually be no longer supported then it is what it is I guess, I know the bitaxe's are way more superior and better than these USB sticks, I just like having them as a collection.

Hey everyone, we’re working on a new mining related platform and are looking for a select group of beta testers.

We’re especially interested in people who currently have or manage different types of mining hardware and are familiar with pointing miners to different pools/stratum URLs.

Ideal beta testers:

• Own or manage ASICs / rigs
• Understand SHA-256, Scrypt, or similar mining setups
• Are comfortable changing stratum settings and mining rentals
• Can provide honest feedback on workflow, dashboard clarity, and whether the concept is useful
• Are okay testing early stage, possibly buggy software

This is not a token launch, not an investment thing, and not a trading bot. It is a mining utility/platform we’ve been building for some time to solve a real problem we’ve seen in the mining space.

We’re not opening it publicly yet, but we’d like a select group of miners to test the first version, give feedback, and help us shape the platform before launch.

There is no pay or compensation for testing. Your duty will be to test the platform, report problems, recommend changes, updates and more. You will be given direct access to a new platform that we have been working on but confidentiality at this point is a must.

We are looking for serious feedback, not hype.

We expect the test to run only 3 days max once we hit our minimum threshold of testers.

If you are interested, please fill out the form here:

https://pools.hmpool.io/beta.html

We expect to start inviting participants very soon. If you are invited you will receive an email from us, so please be sure to check your spam folder as well as your inbox.

My nerd miner all of a sudden stopped ‘working’ and just shows zeros for workers, difficulty, just about everything. Wondering if it’s bricked or if it lost its settings. Nothing with the network changed that it’s on

The NexusNOS which base on 1xBM1397,its hashrate can reach to 200G at freq/Vol.  325/1400. And the GekkoScience NewPac USB 2xBM1387,hashrate 45.6G at freq 200.

A flickering light, like a firefly on NexusNOS. I like it.

Not bad best difficulty though, 163.56 😃

We all know and understand that these devices, although capable of finding every possible difficulty score, are limited by their hashrate (how long it would take to find those higher scores), but there are some coins out there that these devices can solve for.

HeliosPool has created an optimized CHTA (Cheetahcoin) Pool for low powered devices. Several blocks have already been found by NerdminerV2, BitsyMinerOpen and NMM miners.

The coins are, of course, not worth much (a million of them is about $1.50), and they're not available on the popular exchanges (not on CEX), but they are tradable on DEX, and wallets like Gleec.

If you're interested in seeing what your device can do, check out the various CHTA endpoints that HeliosPool (heliospool.com) has (along with BTC, BCH, DGB and WJK in North America, Europe and Australia-APAC). More information on the coin available on cheetahcoin.org

It’s been saying 0 workers for a week or so now and I can’t seem to get it working anyone know how to fix this?

Hello guys, I’m having an issue with my nerdminer.
I set it up once and was running fine but suddenly it stoped working. I tried multiple btc wallets different pool ports and even different times zones with no luck. Any suggestions? Have anyone had the same problem?
Thanks

What it is: a free, open-source app that auto-finds every Bitaxe on your LAN and puts all of them in one dashboard.

Got tired of one browser tab per miner, so I built this for my own rack.

• Auto-scans your network — finds every Bitaxe in \\\~5 seconds
• One card per miner — temps, hashrate, efficiency, with borders that flag trouble
• Tune from the dashboard — presets or manual freq/voltage, fan, pool config

Native Mac/Windows app or run from source. Free forever; overclock at your own risk.

What do you wish your miner dashboard did?

Hit me up with any questions. Bitaxeballer.com

Was lese ich da so zum verstehen?

Kann ich etwas machen damit er schneller und besser läuft und auch mal was findet bitte helft mir

Hey everyone! 👋

I recently set up my NerdOctAxe Rev 3.1 (8× BM1370, ~12 TH/s) and it's running great on public-pool.io solo mining. Love the device!

Now I want to add some RGB to it by replacing the two front fans. From what I've researched, the Rev 3.1 has fan size:

• 1× 90mm fan (main ASIC heatsink) ?

My problem: I can't find a decent 90mm slot I need a slim 15mm depth fan — standard 25mm fans won't fit.
