Oh Lilypads...

18/12/2019

Since Kindred Dichotomy was accepted into AWMAS 2020, I felt it was time to revisit why TRAVIS I's Arduino Lilypad died. My last visit to the USA with TRAVIS I didn't go so well with the wireless connections, so I am a bit anxious to have all wired backups working.

To recap, I was switching back and forth between the Lilypad and the MKR1000 when I was testing something. Then all of a sudden my laptop stopped recognizing this specific Lilypad. Today I still couldn't fix it. But, remember when I posted my comparison of 3 different Arduino Lilypad USBs? It was the blog post on 13/7/2018. I got out my spare Lilypad; it's the one that's not connected to the red glove, and is super jitter no matter what I do with it. When I was making TRAVIS II, there was a slight jitter and I used programming in Max to ignore the jitter when the sensors were at rest. I copied that code for all of TRAVIS I's sensors so now this jittery, "bad", Lilypad is a useable backup.  

Speaking of backups, the wires on the original circuitboard are starting to be a bit short. So instead of replacing the wires, I am using my backup circuitboard. I made it one summer and called it my backup for my backup, in case the solder cracked and I lost a sensor. I never expected to be using it for this situation. I'll revisit the TRAVIS II arduino code and make a wired version to upload in case it refuses to connect too. 

Thinking of the worst case scenario, I don't think all of these wired connections to my Macbook will work in a live performance.  The audio interface needs to be connected too! It's the dumb macbook pro with only two USB C connections. I can imagine myself or my duet partner pulling out the dongles very easily while playing. I'm going to prepare my old PC to handle the visuals for the AWMAS performance. I think for this reason I should prepare both computers to potentially run either the visuals patch or the audio patch. 3 built in USB connections on the old PC is a blessing.

    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.
