The first mass production batch (sapphire) has finished its PCB production and assembly today.

It has significant improvements in:

Heat reduction: 560mA (emerald) -> 500-510mA (sapphire).

Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happen.

Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s.

Appearance:
  Manual assembly (emerald) -> SMT machine assembly (sapphire)
  Standard heat-sink (emerald) -> heat-sink front-case 2-in-1 logo-ed (sapphire).
  LED added.

Four types of front-case:


All of them are eager to be powered up and hashing!


We had shipped the first 200 USBs today immediately after they are out of the factory. Soon more than 10,000 shiny little stones will be distributed international and quietly erupt blocks.

We had shipped the first 200 USBs today immediately after they are out of the factory. Soon more than 10,000 shiny little stones will be distributed international and quietly erupt blocks.

Which means they are already sold out?  Grin

The new ones look awesome!

If you would be so kind to throw in one old heatsink with the shipment to xyt I would be very grateful. I really prefer the industrial design!
