Last edit: June 08, 2013, 04:01:39 AM by friedcat #1 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.



Pictures



Four types of front-case:





Gallaries made by users:





















Changes and Improvements

Color of PCB changed to blue

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).

* cgminer with windows now works (even with the emerald batch).



* Furthermore, the sapphire batch will have much better appearance on the heatsink side. The ASICMINER Project

It's very well priced so it isn't unfair for the buyers OR the shareholder (maximising earnings).



The min. order amount makes it uncomplicated for AM and opens a nice retailer market with good competition.

Hm... i thought these would be good for people with small wallets. Is it the work included to ship many single units or why it the minimum quantity to order 300 units? I thought the shipping is excluded anyway? If its the auction that would become a problem because of to many bids then maybe some website script could be used to automate this. A min of 300 means probably a couple thousand units to be sold. A person couldnt handle it but an automated script could do.



Of course groupbuyers will start new auctions with their batch and start selling to smaller buyers. Is the missed earning worth the work or isnt their missed earning at all?
