      Control is based on USB via my small Netbook. Not yet tested with the BIAB, but well as a 3-tier system some time ago.
      
      Cant wait to test it next weekend :peace:
      
      edit: Should remove the corroded screw :headhit:

      (other problem was a high vaporisation, but thats something easy to handle with).
      
      Is it the small bag? My vessel is 30cm in heights and abput 37cm diameter. My bag got a smaller diameter. Got it from a local shop (in Germany, they git just one...

      Made my new bag and i´m just brewing with it. After removing the bag from the kettle, i got 18L with about 10.2 °P (thats 1.041) - would be a 73% efficiency into boil. Thats better than before :)
