Drilling

8/11/2017

We drilled a hole in the box that will hold the arduino and mounted it on my violin via one chin rest post. Due to the length of the head of the bolt, I had to use the 4 height setting of the Wittner mount so that way the bolt does not dig into the violin. I found that since the box is light, one post is enough. This is great because it means instead of sticking the FSR's directly onto my violin, I can use a piece of wood and mount the FSR's on with the other post. It is also a really good thing that the box is easily detachable because the violin does not fit in its case with the box attached. This affects how I will later hook up all the necessary circuitry because I'll need it to be able to easily and quickly assemble and disassemble.

I had measured how far I can place the 200mm soft pot along the fingerboard without the open string hitting it. It actually goes a lot farther back then expected. If I was in first position on the G string, my 2nd finger first hits it in between a Bb and a B. I believe this makes placing the 150mm soft pot along the side of the neck arbitrary, so I have ordered another 200mm and will have two soft pots placed under my strings. 

I had also tested the the soft pot's and FSR's data coming in on adjacent analog petals. There is no bleeding of data from the soft pot into the FSR like there is when two soft pots are hooked up to adjacent petals. There is something about the FSR that grounds it better. This means that I will hook up my sensors in the following order: soft pot, FSR, soft pot, FSR.

    Welcome to the TRAVIS blog!

    ​If you would like to see a summary of my work, please click here.  

    This blog is where I post updates on TRAVIS I & II as I continue developing them.
    TRAVIS I is an augmented violin that uses two Softpot sensors on the fingerboard to control sound fx, and two FSR's to bang presets.
    ​
    My wired prototype, uses an Arduino Lilypad USB. It was made by myself, and under the supervision of Dr. Bob Pritchard. 

    The wireless version uses an Arduino MKR1000. There was a group of engineering students who collaborated with SUBCLASS. Their names are Jin Han, Esther Mutinda, Carol Fu, and Lily Shao. For their own capstone they are utilized the same MKR1000 for the RUBS (Responsive User Bodysuit).  They named their capstone, WiRED (Wireless RUBS Environment Development). I have been modifying their work for my own purposes, as well as collaborating by making pieces with RUBS. 
    Bob Pritchard continues the RUBS project with TASTE. 

    TRAVIS II is was made in collaboration with Lora Oehlberg and luthier, Aaron Pratte. 

    It has four touch sensors​ made from conductive 3D print PLA and a voltage running down the strings. It also has four round FSRs clamped to the body. 

    You can find a videos and performances here.
