After multiple rewritings of the code, I think I have a solution to the color sensor that reports the correct colors and luminance. I have also (PURPOSEFULLY!) shorted the LED on the breakout board so as to read the ambient light. This has allowed me to close up the assembly and I am prepared to attach this to the buoy body now.<br />
<br />
We have a boat chartered for Monday and so tomorrow I need to construct a camera dolly, get the microcontroller and sensor wires installed in the buoy body, and check the NIR sensor so we are ready for the trip.kidNeutrinohttp://www.blogger.com/profile/13508772133646708142noreply@blogger.com0tag:blogger.com,1999:blog-15764843.post-59387471180769068272019-06-14T09:00:00.000-05:002019-06-15T17:51:39.284-05:00Getting after it: the data buoy project<table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: right; text-align: center;"><tbody>

I am currently Researcher-in-Residence at <a href="http://signalculture.org/">Signal Culture</a> in Owego, NY with my collaborator Sara Gevurtz. We are developing a sculptural installation that monitors the Susquehanna River. The artwork is a two-part system made up by a buoy with sensors in the Susquehanna River and a sculpture located in a public venue. This prototype will be able to record the luminance and color of the water in the river. The buoy transmits this information using IOT methods and the sculpture mirrors the color and light changes.<br />
<br />
I have been working on this idea in rough terms for about 3 years. The Signal Culture residency period will give me the space to make some real headway on the idea.<br />
<br />
During the first day, I was able to make some significant progress on the coding. I put together a rough prototype that allowed me to test out the sensor assembly I constructed with the <a href="https://learn.adafruit.com/adafruit-color-sensors/overview">Adafruit TCS34725 Color Sensor</a>. Here's a video showing my first night's progress: <a href="https://vimeo.com/kidneutrino/review/342497668/e7f1770c5e">Data Buoy 01</a>

Sara Gevurtz and I have been selected to participate in concurrent residencies at <a href="http://signalculture.org/">Signal Culture</a> in Owego, NY. My individual focus is to tackle a data buoy project as Researcher-in-Residence. Sara's individual project will be working with the analog video production gear to databend our images as the Artist-in-Residence.<br />
<br />
We applied to Signal Culture as collaborators as an extension of our long-standing Turbidity Paintings project. At the residency, we will also perform fieldwork on the Susquehanna River. We have chartered a boat to take us on a cruise where we will be recording data, collecting samples, and testing new equipment.<br />

i crashed hard tonight way too early. when i woke around 1030PM, i decided to go for a walk around the Wan Chai district.<br />
<br />
the Hong Kong lifestyle starts late in the day in comparison to my American routine. it is really common for a business not to open until after 10AM, but the place is alive until late, late. after 11PM while wandering the alleys and streets it is not uncommon to discover a popup market splayed unto the roadway that would normally be unforgivingly ruled Hong Kong's red taxi cabs during the daylight hours. i see all manner of produce, fish, and other wares exotic.<br />
<br />
during the late mornings and afternoons the street bustle is extreme and you either get in line of get out of the way, but after 10PM the attitude eases. the night is still overly warm and sticky, but a tad more pleasant now that the sun has been abolished; and with it, the human <br />
flow slows to a stroll, there is time for you to indulge, taste, read. main streets have many little late night food stalls with all the many variations of chimeric asian cuisines. the night becomes bejeweled with neon and led lighting and a hot dirty day is erased. one more stop for me into the local ubiquitous 'circular initial' convenience store for a cheap sticky cold treat to snack on, while i sit in the apartment shared space to handle emails and communications from my Western world.kidNeutrinohttp://www.blogger.com/profile/13508772133646708142noreply@blogger.com0tag:blogger.com,1999:blog-15764843.post-21563699746666700852016-05-11T12:33:00.000-05:002016-05-11T17:42:55.490-05:00field trip <div class="separator" style="clear: both; text-align: center;">

this morning, i talked with <a href="http://www.scm.cityu.edu.hk/profile/DAVID.JHAVE.JOHNSTON">Jhave Johnston</a>, poet, filmmaker, and Assistant Professor at the School of Creative Media at City University of Hong Kong. He is the author the recent release, <a href="https://mitpress.mit.edu/authors/david-jhave-johnston">Aesthetic Animism</a> (MIT Press).<br />
<br />
Jahve has generously offered to meet with us at <a href="https://en.wikipedia.org/wiki/Mo_Tat">Mo Tat</a> fishing village on Lamma Island just south of Hong Kong primarily for a training expedition with the sub. he has also offered to give us a little tour. i can't express enough how lucky i feel and how generous the CUHK CMC community is being.<br />
<br />
there is a pier we can set up on. we will be headed out on Saturday morning. we will ride a ferry out to his place, practice the procedures of running the ROV snapping pictures, and water sample analysis. looks like it is going to be a rainy one, but at least it is warm.<br />

DSL hosts a couple open nights a week and Tuesday's are the HackJam night. the DSL members were very inviting and i felt very at home; the makerspace aesthetic of bits and bobs and stacked equipment. they were my type of peeps. we visited for about 45 minutes discussing 3D printing, scanning, membership organization, equipment availability, and where to get the best deal on electronics. they told us to come back by anytime while we were in town. i will be back.<br />

Ivan Zhao and Annick Lung who work with Jane gave as a little assistance to repair the ROV damaged in air travel.<br />
<br />
we jumped the transit system and headed to Kowloon to sync up with the CU team about 10AM. the Hong Kong MTR is amazing and deserves it own post later. when we exited the train station it began to gently rain. soon the storm turned into a maelstrom of water moving parallel to the ground. we ducked under cover as best we could but the MTR lets out on the opposite side of campus from the CUHK Creative Media Centre. using the buildings and walkways as cover we crossed about 2/3 of the trip as the rain grew harder. we finally found one more covered walkway which ended about 100 feet from the CMC front doors; as we turned the corner there was Jane and some of her students with umbrellas ushering us into the building. Jane got us a moment to sit and gave us tea to smooth the trauma, but we soon got right to it.<br />
<br />
enter, Ivan Zhao, brilliant research assistant to Professor Prophet, who had already cut us multiple copies (and 3d Fdm printed some too) of the file to replace the damaged piece. he consulted with us on the repair and found me a rotary tool to carve away the old piece. Annick Lung also joined us and was very helpful; she helped us make contact with another CUHK professor to advise us on chartering a boat for later in the week.<br />

between the intense rains and the intensity of the repair, the afternoon flew. after getting back from our battles, we found ourselves in a local Hong Kong cafe over heaping plates of eggs, noodles, barbecue pork, and milk tea. reminded me of this:<br />

<br />
Thankfully my hero, amazing artist and Mensch: <a href="http://www.janeprophet.com/">Jane Prophet</a> has graciously offered to host us visit the labs at City University of Hong Kong to laser cut the replacement part to repair the submarine. I was so stressed all yesterday. Jane called me in the late afternoon and connected me with her Senior Assistant Ivan. I am truly fortunate to have such generous colleagues who can make opportunities like this happen.<br />
<div>
<br /></div>
<div>
Ivan is the man; we worked out issues with the file and he confirmed with me. He also gave me a listing for an acrylics place in HK, so if I need to totally rebuild this tube we may have options.</div>
<div>
We will be heading to CUHK at 11AM tomorrow. Wish us luck!!</div>

Sure maybe it isn't as critical as an oxygen scrubber in my tiny tiny capsule, but upon arrival I discovered that the airline had really jostled the OpenROV equipment so hard that one of the battery tube connectors had been broken. NOT GOOD!!! It seems that the Delta boys/girls threw the box around pretty hard and another component smacked the tube. I have ruminated on the issue and I have had several thoughts on mitigation. Add a cushion in that void, don't check the Pelican Box, etc.<br />

The problem is is with that circular piece seen at the bottom left of the image I stole from <a href="http://openrov.com/">OpenROV</a> (thank you guys). These rings retain the battery cap. No bueno!!!! UGGGGGH. 4000 miles to HK, something like this I guess is part of the program...<br />
<br />
<br />
<br />
<br />
Time to solve this, NOW!! So I spent a few sleepless hours until 3AM trying to find some google listings for acrylic and laser cutting outfit but I think there maybe a translation problem. It is unclear if these firms do one off jobs or there are other kinds of solutions. i have put a call into my contact at City University of Hong Kong, maybe she can help us with connecting us with a local group. I am also trying to sync with the local Makerspace: Dim Sum Labs.<br />

we proposed that in the act of capturing abstract images underwater we would also be creating a database of images that could be analyzed by water quality researchers. the title, Turbidity Paintings, is a nod to this idea—turbidity is the measure of particles in suspension in a water column. our project will use two OpenROV units to capture these images and other key water quality data such as nutrients, dissolved oxygen, etc. these data will be used to name the abstract images merging the images into a concurrent state of data and aesthetic object. See: <a href="http://turbiditypaintings.com/">http://turbiditypaintings.com/</a><br />
<br />
the project has gotten some interest in art/science communities and hopefully i will be announcing some other exciting news soon. it has also garnered some attention by environmental science and i have a research assistant from <a href="http://uwf.edu/mschwartz/">Dr. Matt Schwartz </a>at <a href="http://uwf.edu/cse/departments/earth-and-environmental-sciences/faculty--staff/faculty-profiles/">UWF Earth and Environmental Sciences</a>. we began collaborative research initiative and i will be working with Haley, a production/research assistant from that department.<br />
<br />
Colleen and i put in a good 4 hours today; here's a timelapse of Build Day 01. We estimated about another 10 hours of build time until we can hit the pool for testing and learning to drive.<br />

my work over these days has been to learn how to engage multitasking on the Arduino stepping out into interrupts and timer functions in order to measure the data over a longer period or grab two data points and then create a smoothing effect over the light changes. or in other words to take value currentReading - pastReading and divide that difference into 8 steps of change (fading in or out).<br />

i have been really busy with the code on this EEG project and it is not easy.when i really hit the wall but need to get something done i have been focusing on making sure I have good diagrams to repeat the process. here are some of my Fritzing drawings. <a href="http://fritzing.org/home/">Fritzing</a> is an open source diagramming, visualization and PCB layout tool that originated from the <a href="http://www.fh-potsdam.de/">Fachshochschule Potsdam</a>. the tool is invaluable in mapping real world looks at breadboarding and i use it in class all the time to help my beginner students see the layouts. <br />

<br />
<br />
as you can see it makes it very easy to replicate and is a great option for the PCB design/production<br />

today the new knowledge on Gernsback made me wonder about a project i shelved back in 2007. i spent a good amount of time on experiments in micro-broadcasting from 2006 - 2010. i built many FM transmitters from scratch that i used to form small bubbles of influence (temporary autonomous zones). i also wanted to tap into other media such as a colleague's iTunes partition on his laptop. i could broadcast Gary's playlists and mp3s throughout the art department. much of this research came from a sense of independent media and subversion of the bureaucracy official broadcast. the fire was stoked by desire to make handcrafted and to disrupt the culture of corporatized <a href="https://en.wikipedia.org/wiki/Black_box">black box</a> culture. if you don't void the warranty you don't own it.
<br />
<br />
i was reading a lot about the early microradio movement and getting tons of information from Tetsuo Kogawa's <a href="http://www.translocal.jp/">Polymorphous Space</a> website. Here is a link to the famous <a href="http://www.translocal.jp/non-japanese/radiorethink.html">Toward Polymorphous Radio</a>.
<br />
<br />
<br />
in 2007 i built my first TV transmitter. i was able to <a href="http://kidneutrino.blogspot.com/search?q=the+first+broadcast">transmit a picture across the room at the CADRE Laboratory</a> reminiscent of Apollo Moon Landings video. i am reading Peter D'Agostino's anthology <a href="http://www.amazon.com/gp/product/0934378266?keywords=Transmission%20D%27Agostino&qid=1450383514">TRANSMISSION</a> (Tanam, 1985)while at the Signal Culture research residency. i begun to wonder whether i should pick up this line of experiments again. as of today, there are <a href="https://en.wikipedia.org/wiki/Digital_television_transition#Transitions_not_yet_starte">only 7 nations that haven't really begun Analogue to Digital Switchover</a>.<br />
<br />
one of these is CUBA!! a really relevant place to be thinking about right now.<br /><br />

it has been a couple of grueling days of reading and trying to wrap my head around technical methods with the Neurosky data. during that time of reading looking up references and so forth, i have discovered a new inspiration! Hugo Gernsback was an inventor, writer, and editor. in 1925 he presented the Gernsback Isolator, a device to assist you in concentrating and shutting out the annoying distractions of the world. i found these images at: http://www.strangerdimensions.com/2014/12/09/strange-inventions-isolator-1925/

again this my EEG to Systems control research, please see the posts starting 10 December 2015.<br />
<br />
after my initial successes, i then rebuilt the demo with 8 LEDs and cleaned up the wiring to stabilize all the hardware and add additional response range. i practiced for the next couple of hours to develop some control over the system.<br />
<br />
i am seriously impressed with the response can already trigger. i realize that this is a simple graphing of one metric in of the EEG profile, but i have already experienced several characteristics of the biofeedback system that are noteworthy.<br />
<br />
<ul>
<li>it is hard to hold it at a level for a long period of time. i assume this kind of mastery will come with more experience. i can already light the rig with more control after just two hours of practice.</li>
<li>abstraction is helpful - ironically it is easier to concentrate on the video image of the LEDs and get an active response. i am not sure what is at play here exactly but i theorize that when i look at the actual LED array, i also need to visually process the surrounding world and thus distractions are more plentiful. </li>
<li>biofeedback - any self imposed distractions (holding my body awkwardly, tensing up, straining, etc.) actually limits my control. it is very meditative. A musician friend made a conjecture that such feedback could help in voice training so people could monitor the tension in their bodies. Very Jedi indeed.<br />

yesterday, i was able to power up the infernal contraption. i have been merging a Neurosky Mindwave with electronics to develop alternative systems control interface. with all the wires in place a voltage divider built it was time to breadboard. very excited i temporarily built a 4 LED rig based on the Neurosky tutorial (the tutorial called for a 9 or 10 LED array). make sure you are only feeding the receiver module 3-3.3volts!! the TX and RX are fed into the same on the Arduino Uno.<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
i imported the code from the tutorial and had only one small <a href="http://forum.arduino.cc/index.php?topic=121200.0">serial method</a> change to make in order to update it to Arduino 1.0. My adapted code <a href="https://github.com/kidNeutrin0/mindwave_hacks.git">here</a>.<br />
<br />
my next challenge was to pair the headset and receiver. after re-reading the original directions, i realized it was a simple order of operations problem. to pair one must start with both off (including the headset must not be worn yet). power up the receiver module and then power up the headset. you may then put the headset on the subject. anytime i did not follow those directions strictly the system wouldn't pair.<br />
<br />
within minutes i could watch changes in the LED responses; i tracked changes to emotional and tension levels<br />

sigh...<br /><br />
so i sucked it up ordered a piece or two from amazon prime and paid for next day shipping and I will have it tomorrow. i realized as i continued to read up on the reasons why the voltage needed reduction that i could simply build a <a href="https://en.wikipedia.org/wiki/Voltage_divider">voltage divider</a> as the team from <a href="http://www.amazon.com/Make-Mind-Controlled-Arduino-Robot-Microcontrollers/dp/1449311547">Make a Mind-Controlled Arduino Robot</a> had done. this is a simple process where you pass the voltage across two resistors in series leading to fractional adjusted voltage. <br /><br /><a href="http://www.raltron.com/cust/tools/images/voltagedivider.gif" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" src="http://www.raltron.com/cust/tools/images/voltagedivider.gif" style="background-color: white;" /></a>
<br />
there are tons of calculators on the web, i used <a href="http://www.raltron.com/cust/tools/voltage_divider.asp">this one</a> today and <a href="http://hyperphysics.phy-astr.gsu.edu/hbase/electric/voldiv.html">this one</a> in the past to make multi-voltage supplies.

i also soldered wires to the pin-outs on the transmitter/receiver. note the shrink tube on the bundle as a stress relief and careful soldering on bottom to prevent shorts/bridges.kidNeutrinohttp://www.blogger.com/profile/13508772133646708142noreply@blogger.com0tag:blogger.com,1999:blog-15764843.post-59182745606968358352015-12-11T21:17:00.001-06:002015-12-11T21:18:14.809-06:00a side adventure to the thrift shopi decided to go see what i could find at the local thrift shop. the pickings in Owego were modest but i did score two night lights to leave here at the residency site as well as three power supplies all for under 10$. i walked down to the store this place reminds me so much of Eureka CA with the Victorian and Greek Revival wood framed houses.
i stopped into Mario's for lunch, the Manicotti was very good and the garlic knots were amazing.
here's a few images from the walk:

Owego? <p>
Owego NY is the homeland of one of my great grandfather 4 generations ago. when i took up the residency offer, i had no idea. it wasn't until my uncle told me that it became very apparent. i actually have the facsimile of this ancestor Ephraim Lainhart. the Lainharts were Germans who immigrated/settled the Tioga County area and Upstate New York in the 1700's. Lainhart Road still exists today and is the home of a grass fed beef farm Twin Brook Farms.
</p>

</p>
<p>
after i got to town, i went to the Visitors Bureau and they said that they think the Twin Brook Farms owner would probably be open to a visit. i am going to try to make sure i buy and cook a roast from them before i leave. how could i resist the urge

<p>over the next two weeks, <a href="http://signalculture.org/thomas-asmuth.html">i will be practicing/experimenting with using EEG (electroencephalogram) data as a systems control input</a>. yep brainwaves to run name-your-choice-of-physical-hardware. last summer i proposed a theatrical project to enable two actors to run puppetry from their biometrics. that project wasn't picked up and the project was put on the shelf. i applied for the Signal Culture opportunity to give me time to open it once again.</p>

today was a day to look around get my bearings, <a href="http://kidneutrino.blogspot.com/2015/12/really-owego.html">visit ancestral grounds</a> and meet one of the principals in the project. Owego is a town on the banks of the Susquehanna River the are settled since the 1700's has the feeling of a Victorian era boom town built on lumber, farming, and industry. i am just getting familiar and I will tell you more as time goes along.</p>
<p>Signal Culture is in a three story brick building on North Avenue, a main artery through the center of the village. for my time here, i have a spacious 400-500 sq. foot studio with tables, tools and equipment/components. a big bedroom and private bath attach to the studio. the kitchen, dining room/library are on the 3rd floor as a shared resource with the other residents and the founders of the program. i feel incredibly fortunate, and i am very grateful for the support of Signal Culture and the UWF Art Department who have made it possible for me to be here.</p>kidNeutrinohttp://www.blogger.com/profile/13508772133646708142noreply@blogger.com0tag:blogger.com,1999:blog-15764843.post-79695121586706177092013-06-11T20:17:00.000-05:002013-06-11T20:17:01.092-05:00processing study group<p><a href="http://4.bp.blogspot.com/-feWrFQtE8fM/UbfB03T-odI/AAAAAAAAK1k/vq5Y4YvZ0cA/w960-h541-no/IMG_20130611_193318_817.jpg" imageanchor="1" ><img title="woooooooo! installed and working on Ubuntu 12!" border="0" src="http://4.bp.blogspot.com/-feWrFQtE8fM/UbfB03T-odI/AAAAAAAAK1k/vq5Y4YvZ0cA/w960-h541-no/IMG_20130611_193318_817.jpg" style="margin:20px; height:45%; width:45%;float:right; caption-side:bottom;" /></a>i have decided to study up on <a href="http://processing.org">Processing</a> again in anticipation for the Fall semesters classes. i will be doing a study group on Thursday nights at the <a href="http://eccmakers.com">Emerald Coast Community of Makers</a>. tonight, i was able to get an install on the machine at the Makerspace running Ubuntu 12. we will start this week with a screening of Hello World!
