Solo Satoshi Introduces Bitaxe Turbo Touch, An Open Source Touchscreen Bitcoin Miner
A small Texas mining hardware company is releasing what it says is the most powerful open source touchscreen bitcoin miner currently available for home users.
Houston-based Solo Satoshi has announced the launch of Bitaxe Turbo Touch, a compact device designed for hobbyists and home miners that delivers more than double the hashrate of other touchscreen miners in its class.
According to shared note no Bitcoin Magazine, the unit produces about 2.15 terahas per second (TH/s).
The product builds on the open source Bitaxe GT 801 platform and is powered by two BM1370 ASIC chips, the same chips used in the industrial-scale Bitmain Antminer S21 Pro. The chips allow the device to achieve an efficiency of 18 joules per terahash, according to the company. During testing, the device reportedly reached more than 3 TH/s when overclocked.
The miner includes a 4.3-inch capacitive touch screen that displays real-time network and mining data. Eight rotating displays show metrics such as hashrate performance, bitcoin price, current block length and newly mined blocks.
Network information is pulled from mempool.space, a widely used blockchain data explorer.
Matt Howard, founder and CEO of Solo Satoshi, said the company prioritized transparency when developing the machine.
“We built this because we believe the tools people use to interact with Bitcoin should be fully verified,” Howard said in a statement. “All the lines of code between the ASIC chips and the pixels on the touch screen are open source.”

The miner uses two open source firmware layers: AxeOS, which handles mining operations, and BAP-GT-TOUCH, which powers the touchscreen interface. Both software repositories, as well as hardware programs and board architectures, are publicly available under an open hardware license.
The device consumes about 43 watts of power and produces about 35 decibels of sound, putting it closer to the sound level of a quiet room than typical industrial mining rigs. At typical US residential electricity rates, Solo Satoshi estimates that a miner would cost about $3.70 a month to operate.
The Bitaxe Turbo Touch connects via a 2.4 GHz Wi-Fi module using an ESP32-S3 microcontroller, and configuration is managed via a browser-based dashboard. Each unit is assembled in the United States and tested for hashing performance before shipping, the company said.
Solo Satoshi pits the device against other compact touchscreen miners such as the Braiins BMM 101. The company claims that its model delivers the lowest cost per terahash – around $151 per TH compared to the roughly $299 per TH of the Braiins device.
The launch also highlights a growing niche within the bitcoin mining industry that focuses on open source hardware. While many large mining operations rely on proprietary equipment from major manufacturers, small developers and hobbyist communities have pushed for open designs that can be modified and tested.
Solo Satoshi said he worked with the Open Source Miners United community to develop components for the device, including an accessory protocol that allows developers to create additional displays and hardware integrations.
The company traces its involvement in touchscreen miners to the end of 2024, when it partnered with the original Bitaxe Touch concept. When the latest versions of the device were shipped with closed source firmware, Solo Satoshi decided to create his own fully open source alternative.
According to the company, open-source bitcoin miners have collectively generated more than $1 million in guaranteed block rewards, including mining successes that have been widely distributed in recent years.
