Superglue is Insulative...

20/3/2019

I did a few things. First was the JST connectors arrived, so I figured out where it should go for the strings. I didn't solder them yet though. Second was even more troubleshooting issues with the strips…
I spent the past week or so focusing on mechanical issues rather than electrical. I’ve been printing lots of strips because of it, but not testing them. Now I think I have figured out a good relationship between the strips and the fingerboard, so I am testing the resistance again.

One problem is that superglue insulates the header. Too much glue and I lose the connection. I think I developed a way to get it right, but only after accidentally messing up the D and A strips. I tried soaking them in rubbing alcohol and in nail polish remover, it didn’t help.
 
My solution was to first take a soldering iron and press down on the header for about 5 sec so it would sink deeper into the hole. Then I made a cup of hot water and dipped the end into the cup. After that I squeezed the edges so that the header would be wedged in. I added superglue to the outside in order to provide support to the edges. It doesn’t look pretty, but it works.  
 
Then… the above method only worked with the D strip and I ended up ruining all of the headers with superglue anyways...

    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. 

    A summary of my wifi connection troubleshooting can be found here.
