For the first time today we tried to register the chip ID embedded in the 'Add-On' and 'Collector' signs. Dorian transformed a mixed fruit sweet tin into a magic plug that connects to the computer via USB. We noticed that some of the signs don't work - which means testing all 550 signs.
It's quite repetitive ..... Either the chip is soldered the wrong way or the metal casing of the Jack creates a short circuit. - I am glad we noticed now ...
