Introduction
The Block Erupter USB series is the second major product of Bitfountain. Its experimental batch (Emerald) has passed all tests. Each one mines at more than 300MH/s, powered only by the USB port.
It serves as a replacement of GPUs for mining hobbyists. Your GPUs could be freed from calculating hashes and resume rendering for you. It is also a perfect gift for getting people knowing about Bitcoin and Bitcoin mining.
The Emerald Batch
12 in total. Used for internal testing/profiling and gifts for developers.
The Sapphire Batch
This is the first batch under production in quantity. Its lead-time is conservatively 15-20 days.

Four types of front-case:
Gallaries made by users:
Changes and Improvements

Adding a LED which blinks when a share is found
Fixing the cgminer compatibility problem
Reducing the heat generated and the current to <500mA
This batch will be for group-buy and retailers. The quantity of each order should be more than 300 devices. The price is fixed at 1.99 BTC. We will start the group-buy threads as fixed-price auctions in the auction subforum. When your order is fulfilled you could pay and ask for refund anytime before the tracking number is generated (trackable on internet). After shipping we do not refund, but still guarantee a six-month warranty of free replacement like our blades. However the replacement should also come in batch (10 at one time).
Interested purchasers could contact me even before the group-buy threads are created.
