The NerdQaxe is the world's first open-source quad-chip Bitcoin solo miner. It pairs four Bitmain BM1370 ASIC chips with a compact, Wi-Fi-enabled ESP32 control board, delivering industrial-grade hash power in a form factor small enough to sit on a desk. Every hardware schematic and firmware file is publicly available, which means you can inspect, modify, and customize the device to your exact needs. The latest Revision 6.1 from Solo Satoshi is assembled and tested in the USA, removes the one-shot fuse from earlier revisions, adds thicker 1 oz copper traces, and introduces a spring-mounted heatsink for better thermal contact. The result is over 6 TH/s at just over 100 watts when overclocked, with an efficiency of roughly 16.5 J/TH.What are the default and overclocked performance specs for the NerdQaxe Revision 6.1? At default settings of 600 MHz and 1150 mV, the NerdQaxe Revision 6.1 delivers approximately 4.82 TH/s while drawing around 70.6 watts, resulting in an efficiency of about 14.66 J/TH. ASIC temperatures sit near 48 C and VRM temperatures near 41 C under these conditions. When overclocked to 800 MHz and 1250 mV, the device pushes approximately 6 TH/s (many Solo Satoshi customers report stable results between 6 and 6.5 TH/s) at roughly 103 watts, with ASIC temps around 57 C and VRM temps around 54 C. Full performance tables and real-world benchmarks are available on the NerdQaxe product page at Solo Satoshi.How much power does the NerdQaxe consume and what power supply is required? The NerdQaxe draws approximately 70.6 watts at stock settings and up to around 103 watts when fully overclocked. It requires a stable 12-volt DC power supply capable of delivering at least 8 amps continuously, though 10 amps provides comfortable headroom for higher clock speeds and warmer environments. The board connects through an XT30 power connector. Every NerdQaxe purchased from Solo Satoshi can be bundled at checkout with a tested and matched 12.4 V, 10 A, 124-watt power supply and a region-specific C-13 AC power cord available in US, UK, AU, or EU styles. Using a third-party or undersized power supply can cause instability, shutdowns, or long-term stress on the voltage regulators.How loud is the NerdQaxe and can I reduce fan noise? Yes. At default settings the NerdQaxe operates at approximately 40 dB, which is comparable to a quiet laptop or desktop computer. This makes it suitable for bedrooms, living rooms, and home offices without causing disruption. Overclocking increases fan speed and can raise noise closer to 55 dB, which is still similar to a normal conversation. Many Solo Satoshi customers also add the optional rear Noctua fan to improve cooling while keeping noise levels low, even at higher clock speeds.What comes included when I buy the NerdQaxe from Solo Satoshi? Every NerdQaxe purchased from Solo Satoshi ships with the fully assembled and firmware-flashed NerdQaxe Revision 6.1 unit, a quick-start card with a QR link to the full setup guide, and a sticker pack. At checkout you can add optional extras including a UL-certified 12.4 V / 10 A / 124-watt power supply with a region-specific C-13 AC power cord (US, UK, AU, or EU), a Solo Satoshi 3D-printed stand with an 80 mm fan slot, and an 80 mm Noctua rear fan for additional cooling. If you already own a quality 12 V / 10 A power supply with an XT30 connector, the base unit is everything you need to start mining Bitcoin.How do I set up the NerdQaxe for the first time? Setup takes about five minutes. Plug in the included power supply, and the NerdQaxe will broadcast a Wi-Fi signal (SSID) such as "Nerdaxe_78B1." Connect to that SSID from your phone, laptop, or desktop, and a setup portal will open automatically. If it does not appear, navigate to 192.168.4.1 in your browser. Enter your home Wi-Fi credentials, navigate to settings, put your on-chain Bitcoin wallet address (a SegWit address starting with bc1q works best), put in your preferred mining pool credentials, and save. The device will reboot and begin hashing immediately. Solo Satoshi's complete NerdQaxe setup guide walks through every step with screenshots and video.Can I solo mine Bitcoin with the NerdQaxe and what are the realistic odds of finding a block? Yes. The NerdQaxe is purpose-built for solo mining, also called lottery mining. When you solo mine, you compete independently for the full 3.125 BTC block subsidy plus transaction fees. The odds reflect the massive scale of the Bitcoin network. At 4.8 TH/s against a network exceeding 1 Zetahash, the statistical expected time to find a block solo is measured in thousands of years. Despite those long odds, NerdQaxe miners have already found two confirmed Bitcoin blocks in 2025, proving that unlikely does not mean impossible. You can calculate your personal odds at any hashrate using the Solo Satoshi Bitcoin mining calculator.Has a NerdQaxe ever actually found a Bitcoin block? Yes, twice in 2025. The first was Block 913,272, found on September 5, 2025, by a NerdQaxe hashing through Ocean Mining's DATUM setup. The second was Block 920,440, found by a home miner running a cluster of six NerdQaxe Revision 6 units from Solo Satoshi pointed at a self-hosted Public Pool instance on an Umbrel home server. That operator received approximately $342,000 in block rewards. Both events were widely confirmed across Reddit, X, and Bitcointalk, demonstrating that open-source desktop miners can and do win real Bitcoin blocks.What mining pools and solo mining services are compatible with the NerdQaxe ? The NerdQaxe works with virtually any stratum-compatible Bitcoin mining pool. Popular choices among home miners include Public Pool (a zero-fee solo/lottery mining pool), Ocean Mining (which supports DATUM for self-constructed block templates and Lightning Network payouts), Solo CKPool, and Braiins Pool (which offers Lightning payouts for smaller miners). You can also point the device at your own Bitcoin full node running software like Public Pool on Umbrel or Start9 for maximum sovereignty. The latest AxeOS firmware even supports true dual-pool mining, letting you split hashrate between a solo pool and a payout pool simultaneously. Solo Satoshi's guide on mining pools breaks down the pros and cons of each type.How do I overclock my NerdQaxe and is it safe? Overclocking is done through the AxeOS web interface. Open Settings, scroll to Mining Settings, and tap the small square icon to unlock manual input. Raise frequency in 25 to 50 MHz increments, save, and let the miner stabilize for several minutes before making the next adjustment. Only add voltage when frequency alone causes instability and temperatures remain under control. Set fan mode to manual at 100% speed during tuning, and never allow ASIC temperatures to exceed 75 C. Overclocking does carry real risk, including increased power draw, accelerated component wear, possible warranty limitations. The Solo Satoshi NerdQaxe overclocking guide walks through each step with screenshots.What ASIC chips does the NerdQaxe use and why does that matter? The NerdQaxe is powered by four Bitmain BM1370 ASIC chips. These are the same chips found in the Antminer S21 Pro, some of the most efficient industrial Bitcoin miners ever produced. By using four of these chips on a single compact board, the NerdQaxe delivers hash power that once required an entire 135-chip Antminer S7, all while consuming a fraction of the electricity. This chip selection is what allows Solo Satoshi's NerdQaxe to achieve efficiency figures in the range of 14.66 to 16.5 J/TH, making it one of the most efficient open-source miners available today.What is the difference between the NerdQaxe Revision 6.1 and earlier revisions? Revision 6.1 addresses the two biggest pain points of earlier NerdQaxe models. First, the one-shot mechanical fuse on the 12 V rail, which would blow whenever current exceeded 8 amps and kill the miner until physically replaced, has been completely removed in favor of intelligent power monitoring and resettable PSU fuses. Second, the power delivery system has been redesigned with thicker 1 oz copper traces and an improved layout that lowers board temperatures by 21.4% compared to previous revisions. Additional upgrades include a beefier XT30 power connector supporting up to 15 A, a spring-mounted heatsink for uniform pressure on the BM1370 chips, relocated temperature sensors for more accurate readings, and a thicker 2 mm FR-4 PCB. The net result is a 12% efficiency gain over Revision 5. Solo Satoshi's detailed comparison article covers every upgrade in depth.What does open-source mean and why does it matter for Bitcoin mining hardware? Open-source means the hardware schematics, PCB designs (created in KiCad), and ESP32-based firmware for the NerdQaxe are all publicly available for anyone to inspect, modify, and distribute. This transparency allows the global community of developers, engineers, and hobbyists to spot bottlenecks, patch bugs, and contribute improvements, which is exactly how the Nerdaxe platform evolved from a 56 kH/s microcontroller demo in 2019 to the 6 TH/s Revision 6.1 in 2025. Open-source hardware also protects you from vendor lock-in and ensures you are never dependent on a single manufacturer for firmware updates or support. Solo Satoshi works closely with the open-source developers and every purchase directly supports continued open-source development and innovation.Does the NerdQaxe need a dedicated computer or special software to operate? No. The NerdQaxe features an onboard ESP32 microcontroller and runs AxeOS, a web-based operating system accessible from any browser on a phone, tablet, laptop, or desktop. There is no software to install. Once connected to your Wi-Fi network, you simply type the device's IP address into your browser to access the full dashboard, configure pools, adjust overclocking settings, monitor temperatures, and update firmware. The 1.9-inch LilyGO LCD on the device itself also cycles through live hashrate, board temperatures, Bitcoin price, and network statistics so you can check status at a glance without opening a browser.Can I mine cryptocurrencies other than Bitcoin with the NerdQaxe ? The NerdQaxe uses ASIC chips purpose-built for the SHA-256 algorithm, which means it mines Bitcoin natively. It can also mine other SHA-256-based cryptocurrencies such as Bitcoin Cash by pointing the device to a compatible pool or node. However, it cannot mine coins that use different algorithms like Scrypt, Ethash, or RandomX. Solo Satoshi encourages using the NerdQaxe to contribute hashrate to Bitcoin and to be cautious about any third-party claims that a Bitcoin-specific ASIC can mine unrelated coins.Is Bitcoin mining with the NerdQaxe profitable? Profitability depends on your electricity cost, the current Bitcoin price, network difficulty, and whether you are solo mining or pool mining. At default settings, pool mining yields approximately $0.06 per TH/s per day before fees and electricity, which means the NerdQaxe generates modest daily returns that may or may not cover your power bill depending on local rates. Solo mining, on the other hand, is a lottery. You earn nothing until you find a block, at which point you receive the full 3.125 BTC subsidy plus transaction fees. Many home miners view the NerdQaxe as a low-cost way to participate in securing the Bitcoin network, support decentralization, and hold a lottery ticket for a life-changing payout. Use the Solo Satoshi Bitcoin mining profitability calculator to run the numbers for your specific situation.What warranty and customer support does Solo Satoshi provide with the NerdQaxe ? All NerdQaxe devices purchased from Solo Satoshi include a 90-day limited warranty covering manufacturing defects. Beyond the warranty period, Solo Satoshi provides customer support through a ticketed email system to assist with setup, troubleshooting, overclocking advice, and general questions. The team ships from Houston, Texas, offers same-day shipping on orders placed before 12 p.m. CST, and provides insured global delivery with tracking. Every unit is assembled, engineered, and tested in the USA before it reaches your door.How do I update the firmware on my NerdQaxe ? Firmware updates are handled directly through the AxeOS web interface with no extra tools or software required. Connect to your miner's dashboard by entering its IP address in any browser, navigate to Settings, scroll to the bottom of the page, and look for the Firmware Update section. Download the latest .bin release file, upload it through the interface, and click Update. The device will reboot automatically with the new firmware. Keeping firmware current is important because updates often improve hashrate stability, reduce operating temperatures, patch security vulnerabilities, and add new features like dual-pool mining.Can I run multiple NerdQaxe units together and does Solo Satoshi support cluster setups? Yes. Many home miners run multiple NerdQaxe units side by side to increase their total hashrate and improve their solo mining odds. The AxeOS Swarm feature lets you monitor all AxeOS-compatible devices, including Bitaxe miners, from a single dashboard. Each unit connects independently to your Wi-Fi and can be pointed at the same pool or different pools. The miner who found Block 920,440 was running a cluster of six NerdQaxe Revision 6 units from Solo Satoshi alongside another miner for a combined hashrate of approximately 130 TH/s. Solo Satoshi's support team is available to help you plan and troubleshoot cluster setups of any size.Does Solo Satoshi ship internationally and how fast can I expect delivery? Yes. Solo Satoshi ships globally from Houston, Texas, with insured tracking on every order. Domestic orders placed before 12 p.m. CST ship the same business day. International customers receive reliable delivery options, and the NerdQaxe can be bundled with a region-specific power cord (US, UK, AU, or EU) so it is ready to plug in when it arrives. The optional power supply supports 110 to 240 V input at 50/60 Hz, making it compatible with electrical systems worldwide. Many international customers, including those in Canada and across Europe, report receiving their orders within just a few days. If you have questions about shipping to your specific country, reach out through the Solo Satoshi contact page.Is the NerdQaxe safe to run 24/7 in my home and what electrical safety precautions should I follow? The NerdQaxe is designed for continuous, unattended operation. However, safe installation practices are essential. Always use a quality 12 V power supply rated for at least 10 A continuous output. If you purchased the optional power supply from Solo Satoshi, use that unit, as third-party or undersized adapters may damage the device or create hazards. Plug into an outlet and circuit that are in good condition and not already heavily loaded. Keep the miner in a well-ventilated area away from flammable materials, out of reach of children and pets, and do not block airflow around the fan or heatsink. Do not open the casing or modify the internals unless directed, as this voids the warranty. If you ever notice smoke or a burning smell, unplug the device immediately. The AxeOS firmware includes a configurable shutdown temperature (recommended at 75 C maximum) that will automatically power down the ASIC chips if temperatures become unsafe. For more detailed safety guidance, see the Solo Satoshi NerdQaxe setup guide.
