Braiins, the company formerly known as Slush Pool, has unveiled a new piece of hardware called the Forge Miner. It’s a stackable, desk-scale Bitcoin mining rig built around a Raspberry Pi that pushes 4.8 terahashes per second.
The Forge Miner is aimed squarely at solo miners and hobbyists, the kind of people who want to run mining hardware at home without turning their living room into a server farm.
What Braiins actually built
The Forge Miner pairs Raspberry Pi hardware with Braiins’ own software stack for control and operation. The “stackable” part is the key design decision here: users can physically stack multiple units together, scaling their hashrate incrementally rather than making one large capital commitment.
The design also includes customizable airflow panels, which Braiins says are part of iterative improvements focused on cooling efficiency and noise reduction.
The integration with Braiins software is notable because the company’s firmware, Braiins OS, already has a reputation in the mining community. It introduced autotuning capabilities around 2020, which automatically optimize chip performance and power consumption.
Where this fits in Braiins’ lineup
This isn’t Braiins’ first foray into small-scale mining hardware. The company already offers the BMM-100 and BMM-101 series of mini-miners, products that similarly target the home mining segment rather than warehouse-scale operations.
The Forge Miner extends that product line with a stronger emphasis on modularity and expandability. Braiins has highlighted ports for additional peripherals, suggesting the device is designed to grow with the user rather than be a one-and-done purchase.
Braiins has been in the Bitcoin mining business longer than almost anyone. The company operated what was the world’s first Bitcoin mining pool, originally launched in 2010 as Slush Pool. Over the years, it has built out an ecosystem that includes the mining pool (now called Braiins Pool), firmware, and a marketplace for mining hardware.
What this means for investors and the mining landscape
Here’s the thing about 4.8 TH/s: it’s a rounding error compared to what industrial mining operations produce. Modern ASICs from Bitmain or MicroBT can push well over 200 TH/s per unit. A single Forge Miner is doing roughly 2% of what one high-end ASIC can do.
The early reception has been concentrated in niche crypto communities rather than mainstream outlets, which is consistent with limited mainstream media coverage as of early July 2026.
