Yeah, I better do that
.
But, do you own any Ant U3? do you know if there is any equivalent SHA256 miner from another company?
I had one, I eventually gave up on it running stable without much fidgeting about. Others have had more success, yet more others have had even less success
'equivalent' depends on what you're equating it to. I'd assume the small size, in which case there's the
R-Box (not New R-Box), the
GridSeed Orb (also marketed as GridSeed Infinity and GridSeed Mini and
once also sold by LightningAsic under their own branding) and a few devices from
TB (Dice, HEX16A4, HEX16B, opinions about that company are very polarized, so be sure to search first).
Some of the latter are considered rather outdated - going back any further and there's the original Block Erupter Cube, BFL Jalapeno, HashBuster Micro/Nano. Things also get a bit blurry as to whether or not they're really in the same sort of category.
Going forward, there might be the
Avalon Mini,
J4bberwock's SF3301 board (based around GridSeed Orb form factor) and possibly something out of
GekkoScience.
GekkoScience are currently also (pre)selling a USB StickMiner if you'd be inclined to go further toward the small device end.
