NerdMiner V2
An ESP32 educational lottery toy (~kilohash-class) with a display. Near-zero odds — pure novelty and learning.
Overview
The NerdMiner V2 is best understood as an educational toy rather than a real miner. Built on a cheap ESP32 microcontroller with a small display, it 'mines' at kilohash-per-second speeds — many orders of magnitude below even a Bitaxe, and astronomically below any real ASIC. Its purpose isn't to produce hashrate that matters; it's to teach how solo mining and the block lottery work, and to be a fun, glanceable novelty that shows live stats on its screen.
The honest truth is right there in the numbers: at kilohash speeds, the odds of a NerdMiner ever finding a block are so close to zero as to be a mathematical curiosity. And that's fine, because nobody should buy it expecting otherwise. It's cheap, powered by USB, open-source, and it makes the abstract concept of solo mining tangible: you can watch it hash, see the difficulty, and understand what a 'lottery miner' really means.
As a learning device or a gift, it's genuinely charming. It's a great way to introduce someone to how Bitcoin mining works without the noise, heat, cost, or power draw of real hardware, and the little display is a fun desk conversation piece. Just set expectations honestly: this is a teaching toy and novelty, full stop — not a miner in any economic sense. If you want an actual (if still tiny) chance at a block, a Bitaxe is the real entry point; if you want a cheap, delightful way to learn or gift the concept, the NerdMiner V2 is perfect.

NerdMiner V2: frequently asked questions
Can the NerdMiner V2 actually find a block?
The odds are so astronomically small they're effectively zero — it's a mathematical curiosity, not a real chance. It's a teaching toy, not a miner in any economic sense.
Why would anyone buy one?
To learn how solo mining and the block lottery work, or as a cheap, charming gift and desk novelty that displays live mining stats.
How does it compare to a Bitaxe?
A Bitaxe mines vastly faster (terahash vs. kilohash) and has a tiny but real block chance. The NerdMiner is purely educational and novelty.
Is it open-source?
Yes, it's open-source and runs on inexpensive ESP32 hardware.

Bitaxe Gamma
Palm-sized, silent open-source solo miner (~1.2 TH/s at ~15–21W). Best efficiency in the line — and a lottery ticket, honestly.
Bitaxe Supra
Prior-generation single-chip Bitaxe (~0.6–0.8 TH/s). Only worth it if it’s cheaper than a Gamma.
Bitaxe Gamma Turbo (GT)
Dual-chip Bitaxe (~2.15 TH/s). More hash, more heat and power — still lottery economics.
