A small Texas mining {hardware} firm is releasing what it says is essentially the most highly effective open-source touchscreen bitcoin miner presently obtainable to house customers.
Houston-based Solo Satoshi introduced the launch of the Bitaxe Turbo Contact, a compact system designed for hobbyists and residential miners that delivers greater than double the hashrate of different touchscreen miners in its class.
In accordance with a observe shared with Bitcoin Journal, the unit produces about 2.15 terahashes per second (TH/s).
The product builds on the open-source Bitaxe GT 801 platform and is powered by twin BM1370 ASIC chips, the identical chips used within the industrial-scale Bitmain Antminer S21 Professional. The chips enable the system to realize effectivity of roughly 18 joules per terahash, in keeping with the corporate. Throughout testing, the system reportedly reached over 3 TH/s when overclocked.
The miner features a 4.3-inch capacitive touchscreen that shows real-time community and mining knowledge. Eight rotating shows present metrics corresponding to hashrate efficiency, bitcoin worth, present block peak and just lately mined blocks.
Community data is pulled from mempool.area, a extensively used blockchain knowledge explorer.
Matt Howard, founder and chief govt of Solo Satoshi, stated the corporate prioritized transparency when constructing the system.
“We constructed this as a result of we consider the instruments individuals use to work together with Bitcoin needs to be totally verifiable,” Howard stated in a press release. “Each line of code between the ASIC chips and the pixels on the touchscreen is open supply.”
Open supply bitcoin mining
The miner runs two open-source firmware layers: AxeOS, which manages the mining operations, and BAP‑GT‑TOUCH, which powers the touchscreen interface. Each software program repositories, together with {hardware} schematics and board layouts, are publicly obtainable below an open {hardware} license.
The system consumes about 43 watts of energy and produces roughly 35 decibels of noise, inserting it nearer to the sound degree of a quiet room than conventional industrial mining rigs. At typical U.S. residential electrical energy charges, Solo Satoshi estimates the miner would value about $3.70 per thirty days to function.
The Bitaxe Turbo Contact connects by a 2.4 GHz Wi-Fi module utilizing an ESP32-S3 microcontroller, and configuration is dealt with by a browser-based dashboard. Every unit is assembled in the USA and examined for hashing efficiency earlier than delivery, the corporate stated.
Solo Satoshi is positioning the system towards different compact touchscreen miners such because the Braiins BMM 101. The corporate says its mannequin delivers considerably decrease value per terahash — about $151 per TH in contrast with roughly $299 per TH for the Braiins system.
The launch additionally highlights a rising area of interest inside the bitcoin mining business centered on open-source {hardware}. Whereas most massive mining operations depend on proprietary gear from main producers, smaller builders and hobbyist communities have pushed for clear designs that may be modified and audited.
Solo Satoshi stated it labored with the Open Supply Miners United group to develop elements of the system, together with an adjunct communication protocol that enables builders to construct extra shows and {hardware} integrations.
The corporate traces its involvement in touchscreen miners to late 2024, when it collaborated on the early idea of the Bitaxe Contact. When later variations of the system shipped with closed-source firmware, Solo Satoshi determined to create its personal totally open-source different.
In accordance with the corporate, open-source bitcoin miners have collectively produced greater than $1 million in verifiable block rewards, together with a number of extensively publicized solo mining successes lately.
