NerdQAxe++ or Bitaxe Gamma?

The NerdQAxe++ has four times the chips and about four times the hashrate and power. Choose it if you want more hashrate in one box and do not mind the noise; choose the Gamma for a quiet desk miner.

What is the difference between the NerdQAxe+ and the NerdQAxe++?

The NerdQAxe+ uses four older BM1368 chips. The NerdQAxe++ uses four BM1370 chips, which are faster and more efficient.

Which settings do I enter for DirectPool?

In the dashboard settings: Stratum Host stratum.directpool.io, Stratum Port 3333, Stratum User your bc1 address plus .worker, Password x. Save, then Restart.

How loud is the NerdQAxe++?

Around 40 dB, similar to a desktop PC working hard. Fine in an office or garage, noticeable in a quiet room.

How much electricity does it use?

About 670 kWh a year at 76 W, so about 133 a year at 0.20 per kWh.

Does it need a special power supply?

It needs 12 V DC. Most sellers include a 12 V 10 A adapter; if you buy a bare board, get one rated at least that high.

Multi-chip open miners

NerdQAxe++

by NerdQAxe (open source, by shufps), 4x BM1370, open source hardware

The NerdQAxe++ is an open-source home miner with four Bitmain BM1370 chips, the chip used in the Bitaxe Gamma. It hashes about 4.8 TH/s on 72 to 76 W, runs from a 12 V supply that sellers usually include, and is set up over 2.4 GHz WiFi in a browser dashboard forked from AxeOS.

Good and less good

Good

About four Bitaxe Gammas of hashrate in one box, with one supply and one dashboard.
Better efficiency than most small miners, under 16 J/TH.
Open hardware and firmware, actively maintained.

Less good

Noticeably louder and warmer than a Bitaxe; not for a bedroom.
At about 4.8 TH/s, a solo block is still very unlikely. Expect small pool shares.
About 670 kWh a year, which adds up on expensive electricity.

Set it up on DirectPool

The NerdQAxe++ firmware is a fork of AxeOS, so setup works like a Bitaxe: a web dashboard served by the miner at the IP address shown on its screen.

Type exactly this

Stratum Host: stratum.directpool.io
Stratum Port: 3333
Stratum User: your_bc1_address.worker_name
Password: x

Choose your mining region

Showing Europe, Lithuania (main server).

Changing the location only changes the address shown above. Copy it into your miner settings and restart or reconnect the miner. Miners already connected stay where they are. Every server mines the same pool, with the same payouts.

Browser ping, measured live from this page

This measures your browser connection, not your miner or the full relay-to-pool path.

Replace your_bc1_address with a Bitcoin address you control (bc1 or 3). The part after the dot is a name for this machine, so you can tell your miners apart. Addresses starting with 1 are not accepted.

1.Power the miner on. On first boot it opens its own WiFi hotspot called named after the device. Join it from your phone or laptop.
2.A setup page should open by itself. If not, go to http://192.168.4.1 in a browser.
3.Enter your home WiFi name and password. It must be a 2.4 GHz network. The miner restarts and joins your WiFi, and its screen shows its new IP address.
4.Type that IP address into a browser on the same network to open AxeOS, then open Settings (on newer versions, the Pool tab).
5.Fill in the four pool fields with the values above, click Save, then Restart.

Common mistakes

Putting stratum+tcp:// in the Stratum Host field. AxeOS wants the bare host name, with the port in its own field.
Typing the Bitcoin address by hand. Copy and paste it from your wallet so one wrong character does not send rewards nowhere.
Using a 5 GHz network, or a router that mixes 2.4 and 5 GHz under one name. If the miner will not connect, give the 2.4 GHz band its own name.
Forgetting to click Restart after Save. The new pool is only used after the restart.
Flashing Bitaxe firmware. The NerdQAxe++ needs its own firmware from the ESP-Miner-NerdQAxePlus releases.
Boxing it in a cupboard. At 76 W it needs free airflow around the fan and heatsink.

After a few minutes, paste your address on the pool page to see the machine. Small miners can take a while to send their first share.
