The NerdOctaxe Gamma is the most powerful open-source bitcoin miner in the Nerd series. It has 8 BM1370 chips, the same generation as in the Antminer S21, and reaches 9.6 TH/s at about 160 W.
What comes with the NerdOctaxe Gamma?
You get the assembled and tested miner, a LILYGO T-Display S3 screen, two Thermalright AXP90 X53 coolers, a 12V/18A power supply with EU plug and a PlebBase stand in black powder-coated aluminium. You do not need to buy anything else.

Who is this for?
For anyone who wants to mine at home and learn how it works. It will not earn back your electricity bill. The screen shows the hashrate, shares and connection status live.
Solo or pool?
With a pool you combine your hashrate with others and receive small, regular payouts. With solo mining through for example Solo CKPool the chance of finding a block is small, but if you do, the block reward goes to your own address, minus the service fee. The guide to choosing a mining pool helps you decide.
How do you set it up?
You connect the power supply and link the miner to your WiFi through its own access point. The screen then shows the IP address. In the web interface at that address you enter your pool's stratum URL and your bitcoin address as worker name. You do not need an app, account or cloud service.
This miner is an open-source derivative of Bitaxe, the project of the OSMU community. The hardware and firmware files are on GitHub, the original designs on bitaxe.org.
I ship this miner myself from Meppel, so there is no import or customs on your side.
