We were surprised by the huge demand for the Hardware Hacking Kit. Our stock was sold out pretty fast. We reordered the missing parts (particularly the Quad Relay Bricklet) immediately. They were scheduled to be produced today, so we would have been able to ship them tomorrow.
Unfortunately we just got the bad news that the circuits boards did not arrive as scheduled. The circuit board manufacturer does have problems with the raw materials. The new schedule for the delivery of the circuit boards is now the end of next week. That means we will likely be able to ship the currently open orders in week 32.
Apologies for the long waiting time!
