Here is another wall mountable rig - this time its the Spark Miner......
This is a custom-built, wall-mountable Bitcoin solo mining rig assembled from open-source hardware and software components, similar to NerdMiner/BitsyMiner projects. It features four synchronized ESP32-based mining modules, each delivering approximately 720 KH/s

- Four dedicated screens display:
- Per-module current hashrate (~720 KH/s)
- Total hashes processed

- Pool targets, 32-bit targets, blocks found (none to date, as typical for low-hashrate setups)
- System time/date and basic network details (IP address, subnet, gateway, DNS)
Technical Notes:
- Firmware based on the open-source Spark Miner project, with custom multi-screen visualization.
- Connects via Wi-Fi to compatible public mining pools (e.g., Public Pool or similar).
- No ASIC chips – uses ESP32 microcontrollers for lightweight, educational solo mining.
- Power draw is minimal, making it suitable for continuous 24/7 operation in a home or office environment.
Condition:
- New Condition
- All screens, displays, and hashing functions are fully operational
- Includes power cable
- Desk stand and Command strips mounting options
Notes on Solo Mining: This is a true "lottery" miner: success depends on finding a valid block header meeting network difficulty.It is ideal for learning about Bitcoin mining, monitoring network activity, or as a unique tech display piece.
Shipping: Carefully packaged to protect the display and frame.
