      • I was in Geneva last week and clarified the Farnell order and everything, which will be delivered tomorrow.
      • The pacing items are the DigiKey connectors-the ones which connect the flex cable from the LED to the control board : one goes on the LED boards and four on the control boards. These are the ones which will be delivered around 20th August (the last items before stuffing).
      • The LED's were delivered and I carried back in Athens, as well as the 4,000 mini boards.
      • The flex cables have delivery date around 6th of August.
      • I will also start the orders for the control boards,
