Summary
In the fablab I had the opportunity to developed a chair that when a person seats on, turns on a coffee machine though bluetooth. The chair was all done out of snap-fit parts cut in the lab. The electronics in the chair works with a battery, as to make the sistem without cables. The coffee machine was not created in the lab, but is turned on and off with another electronic board, mounted next to the machine.
The chair senses a person with capacitance, so human touch is not directly required yet the chair can differentiate between a pile of books.

The Licenses:
Regarding the license of the objects, I consider it should all be open source. It would be an honor to see somebody else making the chair, and hence I have attempted to provide all the necessary information in order to build it and build on top of it.
Attibution 4.0 International License
I like and admire who has taught me in the past by opening the files and information for me to study and use. The fab as well as Arudino and Opendesk, instructables and tons of others. Hence everything I have developed should be done in the same way.

I figure the more people test work and use it the more a system can grow. If there is any questions or anything I can help out on, my email is info@jhc.design
Acknowledgements
People and organizations crutial for the development of this project are as follows:
| My Instructors: | Alex Tocagon, Roberto & Diana Gallo, and Pablo Núñez |
|---|---|
| Furniture: | Opendesk, Pirwi |
| Code Examples | David A. Mellis (smoothon), Paul Badger (capacitance), Mikal Hart (serial communication), Scott Fitzgerald /Arturo Guadalupi/ Colby Newman(Blink code) & my already mentioned instructor for the proper guidance. |
| Most other things: | From Fabacademy Documentation, most of the time more robust than anything in the web. Aside I have had tons of support from my classmates Ale & Danny, without whom I would have not gotten this far. |
