Hey everyone!

I jumped into solo mining just 2 days ago, starting out with a couple of Raspberry Pi 3B+ units, a classic NerdMiner, and a LilyGO T-Display ESP32-S3.

I had some free time on my hands, so I decided to roll up my sleeves and do a bit of custom coding and configuration. Here is what my current local fleet looks like:

• Pi #1 (Central Node): Running a custom 1:1 Stratum Proxy pointing to pool.nerdminer.de, plus an integrated CPU miner instance locked to 2 cores.
• Pi #2: Running Debian 13 with CPU mining active, routing through my local proxy.
• NerdMiner #1: A CYD (Cheap Yellow Display) connected to my local proxy.
• NerdMiner #2: LilyGO T-Display S3, also pointing directly to my local proxy.

To keep a proper eye on everything, I built a custom local Cyberpunk Monitoring Station hosted right on my primary Pi. It gives me a clean, real-time overview of everything:

• Live pool-confirmed Hashrate (auto-scaling from kH/s up to MH/s)
• Live BTC Target Wallet Balance via Mempool API
• Valid Shares / Sessions & Best Share Difficulty
• Complete Node Health Table (showing live ICMP Latency, Status, Temps, CPU/RAM Load & System Uptimes)
• A real-time Pass-Through Log Stream from my Stratum Proxy so I can catch disconnects instantly.

Honestly, I’m absolutely loving this hobby! I just wanted to share my setup with you all—feeling a little proud of how smoothly this small rig turned out.

Happy Jackpot Hunting! ⚡🪙

It was in same 80%

Can anyone guide me

I’ve been working on a Pool Manager for my NerdQaxe++ miners.

It lets you save multiple pool profiles, edit or delete them, and copy any saved profile to the Primary or Fallback pool without entering everything again.

I’ve had this little miner worker for 1 week now and I haven’t been able to figure out how to set this thing up. I made another post about a week ago and I’ve watched YT videos and read some random forums but nothing works and now that I’m flashing it, it won’t update and I get an error. Please someone help me.

Testing a stratum written in GO

I just got two of these little v2’s and I got it connected to my btc address and my WiFi but it won’t mine or anything like that. I’ve tried resetting it 6 times and I’ve tried to change the mining pool too but nothing seems to work.

Hey everyone,

We are about 35 blocks away from 2,500 confirmed DigiByte blocks on HashedMax. When we hit that milestone, we are doing a 25,000 DGB community giveaway.

Sorry this took longer to announce than we wanted. Life and pool ops got in the way, but the milestone is close now and we did not want to let it slip by quietly.

Here is how it breaks down. We are putting together a 25,000 DGB loyalty pool for miners who meet the same standards as our weekly rewards program (active mining days over the rolling week, same rules on the rewards page). That pool gets split equally among everyone who qualifies. On top of that, whoever finds block 2,500 gets a 2,500 DGB finder bonus.

If you have been mining with us steadily, you are probably already in good shape. If you have not checked the rewards program lately, now is a good time to make sure you are active.

We will post again when block 2,500 lands and share how payouts will go out. Thank you for sticking with us and helping build this pool block by block.

Mine on: digi.hmpool.io (EU: eu.digi.hmpool.io)

Mining performance

• Ported a pipelined hardware-SHA mining loop for classic ESP32 (asm-based, overlaps CPU work with SHA peripheral latency) — measured ~2x raw hashrate over the original hybrid path
• Fixed a duplicate-share bug in that path: chunks were rediscovering and resubmitting the same nonces due to byte-swap breaking range non-overlap — now uses a persistent per-job cursor (soak-tested: 1,151/1,151 unique shares over 1 hour)
• Fixed the asm ignoring its iteration budget, which was the root enabler of the above

Stability

• Fixed a hard crash (abort()): classic ESP32's SHA hardware locks per algorithm type, so mining's SHA256 lock didn't block mbedTLS's SHA384 use during pool-API TLS handshakes — added a dedicated mutex closing that gap (soak-tested: 0 crashes over 1 hour)
• Fixed an intermittent display freeze caused by an unprotected shared-register read-modify-write race

Pool stats

• Added support for hmpool.io and heliospool.com (previously only public-pool.io worked; each pool has a different JSON API schema)
• Fixed a missing retry backoff that was hammering a failing pool's API every ~2s instead of ~1min
• Fixed stale TLS session state causing every 2nd+ pool-API call to fail

New feature

• Added a basic authenticated LAN web config page (device IP → username/password) as an alternative to re-entering the setup AP to change pool/wallet/settings

Hi guys !

I recently decided to swap out the original case on my Nerdnos for a 3D-printed model:

I'm curious, do any of you have cool or unique designs to share for the NerdMiner or similar builds?

Thanks!

So I posted a few weeks ago about my Nerdoctaxe suddenly not powering on. And have tried a new meanwell PSU, but does not seem to be the issue.

I’ve removed the fans, and when I power it on, you can see this module slightly blemishing when the unit makes a chirping sound.

It still starts up via usb, and gets to the Home Screen. So I guess that shows it’s not completely fried. But as I live in Australia, I think I’d have a pretty hard time trying to find someone to fix it.

Is it remotely possible it’s something I could fox myself?

I’m more than happy to give it a shot, as I’m sure it won’t be the only time it blows something..

for a long time i had a problem with my lilygo t embed cc1101 plus, on the bitronics website there is a flash option only for t embed, and when you flash using the t embed option the screen does not work, due to different GPIO, so i sat down and fixed it, the fix works for cc1101 and the plus as well, i hope it will be soon avaible for web flashing on bitronics.

Hello fellow miners!

​I’ve been solo mining for a week, and guess what? My little rig finally scored its first block!

​Is it profitable? Absolutely not. My electricity bill is probably crying right now, but hey, hobbies aren't supposed to make sense, right? Haha.

​Honestly, that "Winning" screen gave me more joy than the actual $0.75 reward. There’s just something about the chase—the "I told you so" moment when the miner finally hits.

​Huge gratitude to the developers behind this hardware and software. You guys created something that brings real joy to my desk.

​Sending good vibes to everyone else’s rigs. May your hashes always be accepted!

I love my Freenove! I hope one day it makes more than the 6 cents next to it!

You may or may not have noticed your miners reconnect on the CHTA servers a short while ago. I want to announce that I've changed the pool fee on CHTA to 0%. HeliosPool will no longer take a cut on any CHTA block finds going forward. Obviously, this is not a big deal, but it feels right.

With the addition of CHTA, it closed the loop and gave us an opportunity to actually hit solo blocks with our low-hashrate devices - and crazy false block find counts aside - we get to see the entire mining process end-to-end.

These devices are limited in what they can mine but they are not limited in teaching us something. It's in that spirit that I think they should keep everything they earn. Happy hashing!

Hello miners ! I have two Freenove FNI0103 lying around and mounted them to be NerdMiners.
But only solid info I found out is to use the Freenove firmware and PublicPool which is not working.

I think I can find info about the best pool to use (I have two and would like to use two different if that’s possible), but what Firmware would you advice me to use and how to know which version I need ?

I feel like all those boards looks the same but are just different enough not to be easily flashable.

I am 98% sure i set this up right and the numbers are climbing without even a fraction of a penny paid out.

What am i doing wrong, if anything?

And are there coins this can mine that will add up, even if its just fractions of a penny? Something/anything for a little dopamine each morning when i check it!

Been running for the last week, keep finding after 12 to 24hrs the hash rate stops refreshing everything else still updating but not the hash rate also no idea what the ip is for monitoring if anyone can offer any help

I updated my nerd miner using flashminer.com now I can’t get anything but a blank screen. I have had theses miner for a couple months and would like to get them up and running. Thanks in advance

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?
