The hackaday prize is the perfect reason to get my idea off the ground. Just started with my project page here, all is new and I propably have to learn a lot. Any suggestions, corrections and comments are welcome!
Right now I started listing the needed materials and will be sourcing them after Easter. Should come in well below 100€ (EURO) for hopefully lots of sensors in all sizes and shapes.
If there is someone who wants to contribute: If I get my sensors up and running I for shure need someone to help extracting heart- and breathing-patterns from the gathered data to reach a proof of concept level.
