Solo miner for SHA-256 coins

The Stellapex NerdOCTAXE 12T is a self-contained Bitcoin miner built around eight BM1370 ASIC chips. It targets hobbyists and home users who want a plug-and-play device for solo or pool mining of BTC, BCH and BSV without external controllers. The open-source Bitaxe web interface handles setup, monitoring and control through a browser.

2.4 GHz Wi-Fi only connectivity

Network access relies exclusively on a 2.4 GHz wireless link; there is no wired Ethernet port. This limits deployment to locations with adequate 2.4 GHz coverage and makes the miner unsuitable for environments that require a wired backbone or 5 GHz-only networks. Latency and stability depend entirely on the local Wi-Fi conditions.

12 TH/s at 240 W with 15 J/TH efficiency

The unit delivers a nominal 12 TH/s while drawing 240 W, yielding an efficiency of 15 J/TH. That output is competitive for a single-device home miner but far below the threshold needed for consistent solo block discovery on the Bitcoin network. Profitability hinges on low electricity rates and pool mining; it will not replace industrial-scale hardware.

Questions about this item

How do I decide between the 12TH/s model and a lower-hashrate version for home mining?

The 12TH/s version uses eight BM1370 chips and draws 240W at 15J/TH, so it fits a standard household circuit while still delivering meaningful daily rewards for BTC, BCH or BSV.

What does 12TH/s actually mean when the miner is running in my living room?

It means the unit performs 12 trillion SHA-256 hashes every second, earning a small but steady fraction of a Bitcoin block reward while consuming about 240W, roughly the same as a desktop PC under load.

Will the 2.4GHz WiFi link limit my pool connection or earnings?

The 2.4GHz band handles the tiny stratum packets used by mining pools easily; your internet uplink, not the WiFi, is the practical bottleneck for share submission.
