Currently you can see the Tinkerforge building blocks at Didacta in Stuttgart at the booth of the Rink GmbH. They make trollies that are used by schools and universities to store class sets of notebooks or tablets. At the trade fair they are showing the new "IT experience box". This trolley has different hardware compenents and tools for projects in the IT area. The new trollies contain Raspberry Pis, mini displays and Tinkerforge building blocks. The content of the trolley can be used to do different experiments. Each experiment has a labled plastic plate with the necessary components, instructions and example source code. The trolly also comes with all of the necessary power supplies.
The booth is in Hall 4.F14 and can still be visited until Saturday.
