Create a software controlling or cooperating with an electronic/mechanic device.
You are free to choose from anything! You should try to piece together your own original device, from whatever spare parts and tools you have at your disposal. However, it needs to have a software component which interacts with the hardware parts.
Creativity is as important as mechanical and programming skills in this section. Your only limit is your own imagination!
The criteria for the finalists are:
Originality (not a copy of another project or a program)
Content, clarity of the documentation
