Bitaxe Hex 302
Six BM1366 chips on one board — the first serious attempt at a multi-ASIC open-source miner. The NerdQAxe line took the idea further with better chips, and the Hex is now effectively obsolete.

What it costs, what it might win
Running costs across the site use this rate. The default is a typical household tariff — check your own bill for the real number.
The odds, honestly
At the current network difficulty of 1.262e+14, a Bitaxe Hex 302 is expected to find a block roughly once every 5.73K years. That is an average across infinite attempts, not a countdown — a block could come tomorrow, or never.
If you pooled instead
Point the same device at a normal mining pool and you would receive the statistical average steadily instead of gambling on it: about $2.97 a month, against $8.69 of electricity. At your electricity rate that loses money — every 151 sats mined costs $0.2856 in power. Buying the same BTC on an exchange would be cheaper.

About Bitaxe
The reference open-source solo miner, designed by Skot and maintained by Open Source Miners United. Bitaxe is a hardware design rather than a company: many vendors build and sell boards from the same public schematics, so quality and price vary by builder.
