Safety Glasses
The concept of the Safety Glasses project is inspired by the Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses of tThe Hitchhiker’s Guide to the Galaxy. These glasses turned completely black at the sight of any danger, to give a relaxed attitude when presented with an alarming situation.
I made a pair of glasses that cover your eyes when you are scared or nervous. These would be specially useful at the movie theater, where some graphic scenes are excruciating enough for covering your eyes. The glasses would have the pulse sensor on an earring clipped to one of the lobes. When the sensor detects an exaltation in pulse servos on both sides of the glasses will close the curtains covering both eyes. The arduino board and two demo buttons are housed in a small plastic box that fits in your pocket.

Searching for the Right Channel 2
This is the improved version of the toy searching for the right channel. This is a clever way for optimizing the amount of animations a lol shield can exhibit, by making some of the led points switches. I painted it white because it matched the Mac remote I was using. Also, I added 3 other animations, CNN, a porn channel, the previous Discovery, and an alien channel. I failed to find the alien channel myself falling as a victim of my own architecture!
Enjoy!

Grove Sound Recorder: PLAY/REC Switching from Manual to Digital
While trying to decipher how to bypass a manual switch with a digital gate, I found transistors to be helpful, but for the sound recorder itself.First I tried to switch an LED on/off. Here is a photo of the LED circuit.
Then I tried to replace the play/ record switch in the sound recorder with two transistors, with this schematic:But I had no luck!
This was the code I used:You will need the library-

Searching for the Right Channel
This project was created using the LOL Shield by Jimmie Rodgers and the IR library by Ken Shirriff. The LOL library and the IR library do not work together because the ISR code in both is using the same timer. I tried combining both libraries and make one of the ISR a separate function and injected into the other, however; it failed, so I had to alter the example code of the LOL Shield without the library and the help of my friend Shawn Lauriat. The idea the came to fruition, using the mac remote I was able to move a dot around the screen. Then if you found the right dot an animation would appear that I coded in with the help of Jimmie Rodgers’s excel sheet. Then the play button would flash all the LEDs at once and the menu button would reset your dot position. Its aesthetic is like a cute TV or a Bomb!

Toccata CalaBach
The concept behind this pumpkin was inspired by the Toccata in Fugue D Minor by Bach. The teeth of the pumpkin are white keys/ switches, that when pressed to the bottom surface close the circuit and play a note through a piezo buzzer. If the first and the last key are both pressed at the same time, a short introduction of the Toccata in Fugue plays. The light of the pumpkin turns on at night, once a photoresistor reads values that are low enough to mean darkness. A little stuffed dead guy accompanies Toccata CalaBach, representing Johann Sebastian.// CODE:

Toccata CalaBach
Toccata Calabaza is an interactive pumpkin design that has different functions based on three inputs. A motion sensor, when triggered plays the Toccata and Fugue in D minor. When the night falls a photoresistor triggers the light inside the pumpkin. A temperature sensor is set to change the lights to flickering orange when it gets colder outside.
Some of the challenges I found in making this pumpkin is that the PIR sensor is too sensitive, so the the Toccata plays constantly. I will have to take off the lens, and perhaps the sound will be more accurate to movement. Another challenge is better representing the chill of the ghost with more than just an orange flicker. Some positive aspects of the project have been learning to compose with PWM, and having to do more research on motion sensing. I’m excited to learn more about music tones with PWM pins.

Hello [pcomp]!!
Background?
Aisen Caro Chacin is a regenerating composition of cells that collaborate to form an independent unit, despite of this precarious human condition. Together they compose a she, a Venezuelan, a Spaniard, an American, and an animal, whose patterns of migration are not based on seasons, but rather chance, chaos, and opportunity. Her curiosity drove her to a career in the Arts, a true trans-disciplinary practice that allows her to dabble between fields and still remain in a coherent path. Her intent has been to question the function and essence of art in order to explore dislocated, un-plotted, un-assigned ideas and social situations. She is also a bucket of ideas open to merge and exchange with other buckets

Circuitry has become a fascination to me and Forrest Mims III a great influence on my latest work. Circuits and microcontrollers are the main reason why I am in MFA DT. After this class I hope to grasp on the Arduino API, and hope to program other chips in place of the prototyping boards.

Maker Faire!
Only the coolest faire ever!
I came out of Maker Faire wired with excitement, inspired to the gills, and ready to make – make – make! I felt at home, I thought I was born in just the right time to experience the fruition of this culture. The culture of the makers and the breakers, where art and science are one, where a science museum shows off the vitality that it attempts to explain. The museum oozed with imagination, everyone was happy to be there together, participating in a huge show and tell. I was inspired to culminating some ideas that have been brewing in my brain for a while, like the sound sculpture albums, and the rain room, and the photo-sound performance wall. In a way I wished I had my own project there, but I am glad I had free reign to explore and find all the knickkancks, experiments, and projects. I loved so much of it, it was hard to pick just 3 to talk about. So to do the rest of the projects justice, I will post pictures of the rest.Interfaces:
The most amazing, beautiful, poetic piece in Maker Faire NY 2011. This swing set had a curtain of rain that would switch off as the swing would pass directly under the curtain. This work reminds me of a piece I’ve been wanting to make for a while now, a rain room that partitions the rain as you walk through. As far as interfaces, this is the most successful blissful work. Though I dared not to try it, since I saw a few girls get wet. I think the switches were not always working properly. Regardless of the switches, if it wasn’t for the cold or the line, I would have loved to swing by.
This piece created by Luis Violante is also endearing to me, since I have an utter fascination with microscopes. I’ve had one since I was a kid. In the Imagine Scope, Violante used a mini projector to play movies through the microscope viewfinders. The slides each had a magnetic chip that one could scan by placing it under the lens. Then depending on the slide you picked a movie would play. This interface is successful in many ways. Conceptually, it is taking the situation of watching films and redirecting it to a different point of view, perspective. It invites us to analyze these short films as carefully as biological specimens in a petri dish. Also I find the use of the mini projector a very clever way of displaying affection to the miniature world. This piece is just fantastic, the video selection was wonderful. I had the delight to see a compilation of images collected from one of the earliest space explorers.
This Austin band is so cool. They use 4 huge tesla coils to amplify their sound. I had seen a video of their performance before, and luckily got the opportunity to dee them live at maker faire. The only disappointing aspect, was that instead of having a band member in chain maille and armor conducting the band between the 2 coils, they had a metal cage. Members of the audience were invited to hang out in the electrocuted cage for the duration of a song- and honestly this was boring. It made a spectacle of a perfectly awesome band.

This project was surprising in all aspects. Having left the practice of making projects every week since the brake reminded me that it is practice that makes perfect. It is important to keep these skills current. The delay threw me off! having to rename it so it can be checked and not interfere with other commands was the most unexpected challenge this project brought to me. Also, I forgot how fun it can be to find beautiful colors rather than have the cycling rainbow effect. This project brought me back to my earthy roots, I am glad to incorporate sand and its other state silicon.
