The Art and Economics of Manufacturing a Bitaxe: A Deep Dive into Decentralized Mining
Bitcoin mining has come a long way since the days of CPU rigs humming away on bedroom desks. Today, it’s a high-stakes game dominated by industrial-scale operations wielding cutting-edge ASICs (Application-Specific Integrated Circuits). But at Plebsource.com, we’re flipping the script. Our mission is to bring mining back to the people—hobbyists, tinkerers, and freedom-loving plebs who want a stake in Bitcoin’s decentralized future. At the heart of this revolution is the Bitaxe, an open-source Bitcoin miner that’s as scrappy as it is powerful. Today, we’re pulling back the curtain on what goes into manufacturing a Bitaxe, with a focus on the Bitaxe Gamma, its priciest component—the BM1370 chip—and how we’re working to drive costs down to supercharge mining decentralization.
The Bitaxe: A Rebel with a Cause
Before we dive into the nuts and bolts, let’s set the stage. The Bitaxe isn’t your average miner. Conceived by electrical engineer and Bitcoin enthusiast Skot (

on X), it’s the world’s first fully open-source ASIC-based Bitcoin miner. Unlike the proprietary behemoths from Bitmain or MicroBT, the Bitaxe is designed for the everyman. It’s compact, low-power, and WiFi-enabled, making it perfect for a garage, basement, or even a dorm room. Models like the Bitaxe Gamma pack a punch—1.2 terahashes per second (TH/s) from a single chip—while sipping just 15-18 watts of power. That’s efficiency with attitude.
But building a Bitaxe isn’t like assembling a mass-produced gadget off a Shenzhen assembly line. It’s a labor of love, a blend of ingenuity and grit, and it starts with sourcing the right components. At Plebsource, we’re obsessed with keeping costs low and quality high, all while staying true to our anarcho-capitalist ethos of dismantling centralized mining empires. So, what does it take to make one of these little rebels? Let’s break it down.
The Anatomy of a Bitaxe Gamma
Manufacturing a Bitaxe Gamma involves a handful of key components, each with its own story:
  1. The BM1370 ASIC Chip: The beating heart of the Gamma, this chip delivers the hashing power. It’s also the most expensive part—more on that in a sec.
  2. PCB (Printed Circuit Board): The backbone that ties everything together, custom-designed to host the BM1370 and other electronics.
  3. Cooling System: A 40x40mm heatsink and a 5V PWM fan keep the chip from frying itself during operation.
  4. Microcontroller: An ESP32-S3 module handles WiFi connectivity and runs AxeOS, the open-source firmware.
  5. Display: A removable 0.91" SSD1306 OLED screen shows real-time stats like hashrate and temperature.
  6. Power Supply: A 5V, 25W PSU with a 5.5x2.1mm barrel jack powers the whole setup.
  7. Miscellaneous: Thermal compound, connectors, and a 3D-printed stand round out the package.
Each piece is critical, but the BM1370 chip is the star—and the bottleneck. Let’s zoom in on why it’s such a big deal.
The BM1370: A Chip Worth Its Weight in Sats
The Bitaxe Gamma owes its prowess to the BM1370 ASIC, a chip originally designed for Bitmain’s Antminer S21 Pro and S21+. This little beast cranks out 1.2 TH/s at an efficiency of around 15 joules per terahash (J/TH), making it one of the most powerful single-chip solutions for home miners. But there’s a catch: Bitmain doesn’t sell these chips standalone. To get one, you’ve got to crack open an S21 Pro or S21+ and pluck it out manually. That’s right—every BM1370 in a Bitaxe Gamma is a second-hand chip, carefully extracted from a $3,000+ industrial miner.
This manual process is as tedious as it sounds. Picture a skilled technician disassembling an S21 hashboard—home to 65 BM1370 chips—unsoldering each one with precision tools, testing it for functionality, and prepping it for reuse. It’s a time-intensive, labor-heavy job that drives up the cost. On average, a single BM1370 chip fetched this way runs between $30 and $50. Compare that to older chips like the BM1397 (used in earlier Bitaxe models), which you can snag for $15-$20 in small batches, and you see the problem. The BM1370’s price tag is a major hurdle to scaling production and keeping the Bitaxe affordable.
Why not just buy new chips? Bitmain’s closed-source ecosystem locks down the supply chain. They don’t release ASICs individually, and their documentation is sparse, leaving innovators like Skot to reverse-engineer everything. It’s a classic case of proprietary gatekeeping clashing with open-source ideals. At Plebsource, we see this as a challenge to overcome, not a roadblock. Driving down the cost of chips like the BM1370—or finding alternatives—is key to broadening mining decentralization, and we’re all in on that fight.
The Manufacturing Process: From Chip to Chassis
Once the BM1370 is in hand, building a Bitaxe Gamma is a multi-step dance. Here’s how it comes together:
  1. PCB Fabrication: The custom PCB is designed using open-source schematics (thanks, Skot!) and sent to a manufacturer. These boards are small—about credit-card-sized—and packed with surface-mount pads for the BM1370 and other components. Cost per board? Around $5-$10, depending on volume.
  2. Component Sourcing: The ESP32-S3 module ($5-$7), heatsink ($2-$3), fan ($3-$5), OLED display ($4-$6), and PSU ($10-$15) are sourced from suppliers like AliExpress or Amazon. Quality matters—cheap fans can fail, and subpar PSUs might not deliver stable 5V power, frying the rig.
  3. Assembly: This is where the magic happens. Surface-mount assembly machines (or skilled hands with soldering irons) place the BM1370 onto the PCB, followed by the ESP32, connectors, and other bits. High-quality thermal compound (like Thermal Grizzly Kryonaut, ~$5/tube) is applied between the chip and heatsink for optimal heat transfer. Total labor cost per unit? Around $10-$20, depending on automation.
  4. Testing: Every Bitaxe gets powered up, flashed with AxeOS, and stress-tested. Does it hit 1.2 TH/s? Does the fan spin at the right RPM? Any duds get reworked. This step adds another $5-$10 in time and electricity.
  5. Packaging: A 3D-printed stand (pennies to print) and basic packaging wrap it up. Total cost here is negligible—under $2.
Add it all up, and a Bitaxe Gamma’s raw material and labor cost lands between $75 and $120, with the BM1370 eating up 25%-40% of that budget. Retail prices hover around $150-$275, reflecting margins, overhead, and the niche market. It’s a lean operation, but that $30-$50 chip looms large.
The Cost Conundrum: Why It Matters
At Plebsource, we’re not just building miners—we’re waging war on centralization. Bitcoin’s security relies on a distributed hashrate, but industrial farms with their economies of scale threaten to hoard it all. The Bitaxe fights back by putting mining power in the hands of hobbyists. Problem is, at $150-$275 a pop, it’s still a stretch for some plebs. That’s where cost reduction comes in.
The BM1370’s price isn’t just a manufacturing headache; it’s a barrier to adoption. If we could slash that $30-$50 down to $10-$15, the Bitaxe Gamma could drop below $100 retail. Imagine thousands more rigs humming in homes worldwide, each one a tiny bastion of decentralization. That’s the dream. But how do we get there? Two paths are emerging: alternative chips and industry disruption.
Path 1: New Chips, New Hope
Skot’s been tinkering with a game-changer: the BZM2 chip from Intel. Unlike the BM1370, the BZM2 isn’t the bleeding edge of efficiency—think 20-25 J/TH versus 15 J/TH. But it’s got a killer advantage: availability. Intel has reportedly handed out BZM2 samples for free to developers and enthusiasts, a stark contrast to Bitmain’s walled garden. If Skot’s design pans out, a Bitaxe with a BZM2 could cost pennies on the chip front, driving the total build price well below $100.
Sure, the BZM2 won’t match the Gamma’s raw performance. A single chip might top out at 800-1000 GH/s (0.8-1 TH/s), but for solo miners chasing the “Bitcoin lottery” (a full block reward of 3.125 BTC plus fees), hashrate isn’t everything—luck is. A cheaper Bitaxe with a BZM2 could flood the network with small rigs, boosting decentralization without breaking the bank. At Plebsource, we’re cheering Skot on. A free chip is a libertarian dream—power to the people, not the corporations.
Path 2: Disrupting the Supply Chain
Meanwhile, other players are stepping up. Companies like Auradine are shaking things up by engaging with outfits like Futurebit.com to rethink ASIC production. Futurebit’s Apollo miners already cater to hobbyists, and their push for accessible, non-proprietary hardware aligns with our ethos. Auradine, a newer name in the game, is reportedly exploring ways to mass-produce ASICs without the Bitmain stranglehold. If they crack it, we could see BM1370-grade chips—or better—hit the market at $10-$20 each, no manual extraction required.
This isn’t just about cost; it’s about efficiency and power. A Futurebit-Auradine collab could yield chips that outpace the BM1370 (say, 10 J/TH or 1.5 TH/s per chip), giving hobbyists more bang for their buck. Pair that with Plebsource’s lean manufacturing, and we’re talking Bitaxe models that are cheaper and more computationally powerful. The tedious process of plucking chips from S21s could become a relic, replaced by a steady supply of affordable, open-market ASICs.
The Bigger Picture: Decentralization at Scale
Why obsess over a few bucks per chip? Because every dollar shaved off a Bitaxe is a step toward mass adoption. Bitcoin’s hashrate is staggering—over 600 exahashes per second (EH/s) as of March 2025. A single Bitaxe Gamma’s 1.2 TH/s is a drop in that ocean, but multiply it by 10,000 units, and you’ve got 12 PH/s (petahashes per second)—a meaningful chunk. Now imagine 50,000 units with cheaper BZM2 chips or Auradine alternatives. That’s 40-50 PH/s, enough to nudge the needle on network security.
This isn’t fantasy. The Bitaxe community is growing—over 4,000 contributors have joined Skot’s open-source movement. Solo miners have already struck gold; a Bitaxe found a block in July 2024, netting 3.125 BTC (worth ~$280,000 at today’s $90,000/BTC). It’s proof that small rigs can win big. At Plebsource, we’re not just selling hardware; we’re arming an army of plebs to keep Bitcoin’s ethos alive—one hash at a time.
Challenges Ahead
It’s not all sunshine and sats. Scaling Bitaxe production faces hurdles:
  • Supply Volatility: BM1370 availability depends on S21 stock and extraction capacity. A drought could spike prices.
  • Competition: Industrial miners won’t sit idly by. They’ll push efficiency (e.g., Bitmain’s S21 Hydro hits 7 J/TH) to widen the gap.
  • Energy Costs: Even at 15-18W, electricity bills add up. Hobbyists in high-cost regions might balk.
But these are problems worth solving. The BZM2, Auradine, and Futurebit efforts are wildcards that could flip the script. And as Bitcoin’s price climbs—potentially hitting $100,000+ post-halving—the incentive to mine grows, even for small fry.
The Plebsource Promise
Manufacturing a Bitaxe is more than a process; it’s a statement. At Plebsource.com, we’re committed to driving costs down, not just for profit, but for principle. The BM1370’s $30-$50 price tag is a hurdle, but it’s not insurmountable. With Skot’s BZM2 design, Auradine’s innovation, and Futurebit’s grit, we’re on the cusp of a new era—cheaper Bitaxes, more powerful options, and a hashrate that’s truly of the people, by the people.
So, whether you’re a garage tinkerer or a libertarian dreamer, grab a Bitaxe Gamma from Plebsource and join the fight. The empire of proprietary mining won’t crumble overnight, but every rig we ship is a brick pulled from its foundation. Together, we’ll decentralize Bitcoin mining at all costs—because freedom isn’t free, but it damn well should be affordable.
