Testing of the first fingerboard strips!

9/3/2019

0 Comments

 
Printing the actual fingerboard strips are a bit more of a challenge than the test strips, because the top surface is curved. Layer height 0.1mm, Infill Density 70%, Pattern: Triangles.
 
EStrip_Short.stl
E strip is on a bit of an angle, so I had to rotate it flat in Cura. The problem is, is that it is difficult to tell if it’s rotated properly or not. There is a bit of overhangs inside the tracks that need to be picked out. It’s also a little on the rough side as it gets closer to the nut end, but not too bad. The header hole is perfect.
 
The resistance fluctuates a lot at the ends.

Turned out similarly to the E. I think the overhangs are a bit better though.

This is better than the G and E strips. Probably because the bottom is flatter. It was made with support checked off.

First time I printed, it turned out ok. However, the nut end was peeling off the build plate and it not useable. I’ll try again with it flipped over.
 
The flipped over orientation was fine. I don’t know what went wrong before, because I printed all the other strips this way before. I tested the 2nd print, not the first print.

    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.
