@BlockVisn @Braiins We are working on it! Like literally right now.

UPGRADE: Braiins OS 26.06 is live 💥

Smoother tuning in the heat, new hardware support, and better visibility into your miners.

1️⃣ Continuous Tuner improvements
• Reacts instantly to rapid temperature swings for smoother operation
• Holds a more stable hashrate in high-temp environments
• Better filtering from chip temp sensors means fewer pauses

2️⃣ New hardware support
• Antminer S21e Hyd. hashboard variant H6HB70802
• Antminer S21 XP Hyd. variant H6HB70502 (LM75A temp sensor)

3️⃣ More accurate chip temperature readings. Improved sensor filtering gives you cleaner data and cuts down on unnecessary pauses.

4️⃣ Better visibility in logs and GUI. PIC/no-PIC identification now shows in the GUI, bosminer logs include API calls made to the miner, and PSU serial numbers appear in the logs.

5️⃣ Braiins Mini Miner 101: fixed the IP report button performance on the BMM101.

Not usually a fan of these 'bitcoin credit cards', but this (prepaid) one caught my eye because it doesn't have KYC.

@SatStackingPleb @Braiins @luxor Thanks! Yes exactly. Definitely don't want to claim the feature is the same.

@satsdisco You sleeping on storage chip prices? It's the next moon!

I'm hodling my 4 TB SSD for retirement.

UPGRADE: Braiins OS 26.05 is live 🔥

Beat the summer heat with thermal auto-recovery, plus more flexibility and security upgrades.

1️⃣ Thermal Auto-Recovery
- Miners shut down at 90°C to protect hardware
- Auto-Recovery resumes hashing after 3 hours, no manual restart needed
- On by default for AC and immersion miners
- Configuration → Advanced → Auto-Recovery After Overheating

2️⃣ Support for PSUs without voltage feedback
- Pair a no-PIC miner (like S19 XP) with a PSU from a PIC miner (like S19J Pro)
- Hash with the parts you already have
- Configuration → Advanced → Allow missing voltage feedback
- Recommended only if you understand the risks

3️⃣ Startup delay
- Stagger rig startup after curtailment to manage power draw
- Set a max delay and miners start hashing within that window
- Configuration → Advanced → Maximum Startup Delay

4️⃣ The autotuner now adjusts voltage to hold power consumption steady as temperature shifts. Performance drop? It re-tunes automatically.

5️⃣ Security: CGMiner API Read-only by default. For full control, we recommend the Braiins API.

@BitcoinErrorLog Often ponder about a P2P marketplace for renting home internet connections. But I fear it's a recipe to get rekt.

Gotta fax them all!

Love it when people are so fax forward (German only) https://t.co/WV2lcABUhL

But sending it to the Dutch military is still possible

@onebillionsats I'll take a fresh lightning invoice please.

[sime @simonmales]

@magic__smoke I like the IR port. Any scope for a case?

[sime @simonmales]

@DuaneJe19915983 @WilsonMining @Braiins Continuous Tuning works on my BMM101

@BitcoinErrorLog Stopped paying for lunches with Lightning thanks to MiCA.

[Bitcoin Fax @bitcoinfax]

Woo! River mentions Bitcoin Fax as a project supporting the lightning network :)

(check the whole image at the end of the post)

Don't poo poo on the fax machine just yet.

Look mum, I'm on the TV!

Sharper thermal control. More uptime.

When mining conditions get extreme, like the recent polar vortex in North America, firmware makes the difference.

Over 2 GW of hashrate worldwide is protected and powered by Braiins OS. With 26.01, that protection gets even stronger.

📣 Introducing Braiins OS 26.01.

Dynamic Performance Scaling (DPS) is now enabled by default. Miners automatically adjust power instead of shutting down when temperatures spike, helping maintain uptime when conditions get tough.

Hardware support continues to expand. Hydro is shaping the future of mining.

✅ S21e Hyd.
✅ S21 XP Hyd.
✅ S19 XP+ Hyd.

Additional improvements and fixes included.

Update today.
