Ok, tempted to pull the trigger on one of these units. Shipping to USA.
- How is it so cheap ?
- On-board ethernet ? Wireless ? USB ?
- Dimensions of product ?
- Power supply ?
- If I place an order, and there is no significant product update in the next 29 days, I can be refunded my 32BTC ?
- When are working prototypes expected ?
- How long has this been and development, and what stage are they presently at ?
1) Once you produce the mask for the chip, the chips themselves cost you nothing. I would not be surprised if 24 chips to make up the 120Gh/s cost them more than 24$ to make.
2) We do not know for sure what the exact specifics of the PCB board itself yet. We're still going through various posts, translating and reading so that we can make a determination. At this time it does appear it will be a stand alone unit thought it is unknown if there will be ethernet AND wireless or just one of the two.
3) Unknown at this time. I believe the focus has been on the chips; I'm not sure if they're running PCB design concurrently or planning to do the design once the chips are finished (or if the design is already done).
4) Yes, We're offering a full refund within 29 days of your order.
5) The chip is expected to be tested and proven in the next 30 days (waiting on the production).
6) The initial prototypes will be produced after the first batch of test chips have been tested and proven.
7) It was announced in April 2013 but there is evidence that bitfury was working on the design prior to that (Aprox 1 year ago). The current stage as i mentioned above, they are presently waiting on the initial batch of chips to be printed and tested thus proving the design. After that they will go into mass production.
