Diego's ITP Projects

The bedData project takes sensor values from 90 FSRs that Mustafa Bagdatli and I built over the summer in hopes we could visualize your bed habits. The FSR matrix is composed of 6 columns and 15 rows. We began installing the sensors on Thursday October 29 on the “nap station” here at ITP. Matt Richard joined us and helped create a snake game that is controlled by rolling around the bed. Matt also bundled all the visualizations into one processing sketch. Thanks to Michelle Myer for taking a few shots of our process.

Concept: To be able to track and represent your unconscious and conscious behaviors in bed.

Software: Processing and Arduino

Hardware: Arduino, 6 analog multiplexers, plenty of wires, and DYI FSRS.

Visualizations:

• BlobTracking
• CircleMatrix
• SnakeBed

Process:

90 sensors were built during the Summer (June’09).  Nothing happened.

We spent about 3 days setting up the hardware until we were able to read all sensors. The sensors are about 5 inches apart and are connected to a terminal that then connects all sensors to the multiplexers.

The mux shield for the arduino came in on friday, here is what Mustafa created:

Here are some videos from Sunday night:

Lessons Learned:

• Stick with breadboards for any sort of prototyping
• Wire manage!
• 10k resistors can smooth out values
