This is yet another milestone on my journey to combine the Hexiwear with the Raspberry Pi: now I can send take over control of the Hexiwear with openHAB running on the Raspberry Pi:

How to fascinate kids for technology? Show them that engineering is fun :-). At the Lucerne University of Applied Sciences and Arts we have created the ‘MINTomat’: a robotics system for STEM activities rewarding interaction with bubble gums:

Yes, pretty over engineered compared to a normal bubble gum automata, but that’s part of the fun :-).
The first enclosure for the INTRO robot remote controller board (see “INTRO Robot Remote – First Production PCB“) is ready, and it is looking good:
Enclosure for the Remote Controller Board
After the first prototype (see “Prototype of Wireless Remote Controller with NXP Kinetis K20“), we have received the boards and populated a first PCB to verify everything is working properly.

For next semester I plan to use the tinyK20 as a remote controller for the Zumo Robots. I already had an early prototype presented in “3D Printed Gameboy and Remote Controller with tinyK20 Board“, so here is the next iteration of, in a sneak preview:
Remote Controller Prototype
We are using robots to teach advanced embedded system programming at the Lucerne University (see “Sumo Robot Competition“). Students can buy the kit, and we are running out of available hardware. Time to produce a new series of robots :-). It took us a while to get to the next revision of the Zumo Robot, but finally the first one has been produced and assembled, and I think it is looking good :-).

I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to the Micro Amps“). I have that transceiver now running with the tinyK20 board too:
