only 200 shipped
will forward news asap

I still haven't all addresses

damit wären meine Andeutungen was einen anderen ebenen Kühlkörper angeht wohl aus dem Sack  Grin
Umpacken in ESD-Folie hat sich mit den schönen Boxen dann auch erledigt

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.
