I've heard elsewhere that there are some guys working on a faster chip for mining litecoin! does anyone knows if that is for sure? a alchemist guys say that they have a powerful chip! Maybe a rumor? I've lost the source of that information, can't confirm!
Alcheminer? Yes, they have a usb miner plus a larger miner.
http://www.alcheminer.com/ <--- No usb miner, the usb is made by Futurebit.
there's the Futurebit Moonlander that uses the Alcheminer chip, runs up to 1+mh/s that's made for scrypt mining, and matching software for it. The thread is found at
https://bitcointalk.org/index.php?topic=1248914.0It's not sold by jstefanop anymore, but there's plenty of resellers (Asicpuppy used to sell them, but they ran out) on Amazon and eBay. If you decide to get one, it's basically the Gekkoscience Compac of the Scrypt world- plenty of overclocking and modding possible, and made by the community. Alcheminer also sells their own miners if you'd like to get one, but personally I'd spend my money supporting forum members than some company I don't know well.
