7 SEGMENT LED ASSIGNMENT

So for the Advanced Microcontroller class we had to build a seven segment LED and program the PIC (in this case PIC 16F819) so that it would count from 0 to 9. It was a great excercise for me to get my hands on the PIC programmers and PicBasicPro since my only experience other than the Arduino was with BASIC and BasicStamp2.

This is the PIC originally wired on a board ready to receive IR.

This is the 7-segment LED (from RadioShack because the one given out in class had a little, burning accident!!!)

This is the changing 7 Segment, yes, very exciting!

Now i am thinking about taking this a few steps further and maybe getting my hands on some GPS technology to make a wall clock similar to the one at the Sparkfun office (http://www.sparkfun.com/commerce/present.php?p=GPSClock-1).

We'll see!!!

OBSERVATION FOR P-COMP MIDTERM

As usual, my observations are really basic, but it's because i believe that more often than not, we take little things and big things as well, for granted. Thinking that we know everything, or that we know the outcome of things or that we have seen that specific thing or something like it, before. I think as human beings, we don't know s**t. And, as i said, i think more often than not we are WRONG. Or just simply absent minded, absorbed in our own heads, in our faulty thought process or some other mundane aspect of our life. Ok, maybe i am being a little pessimistic, or i just simply had a bad night... nonetheless i think it's pretty close to being true, at least for me.

So, as obvious as it might sound, i decided to have 3 people play the same piece of classical music on a classical guitar and observe. Sorry i have no images up here, but i lost my crack copy of Final Cut and i couldn't digitize the DV tape on time.
The piece is a very sweet love piece of classical guitar music that some call Romanza and some call differently because it's an anonymous author. It's one of my favorite pieces of simple classical guitar music.

I played it, my friend Gadi (jazz musician/musical synthesis engeneer) played it and so did my old woodwork teacher from Boston, Walter. Again, it was a fairly simple excercise, but i was surprised about the fact that a short, fairly straightforward piece of written music could be played in such different manners by the 3 of us. Not one version was similar to the next. Everything differed, from the way we held the guitar (i held it close to how you hold a classical guitar, but not quite; Gadi held it like a regular guitar; Walter played it in the most proper way) to the way the strings were struck, from our posture, although we were all sitting, to the way the music sounded after all. And again it might have been something very predictable, but by looking at the sheet of music i would have never guessed.

Classical guitar is, in my opinion, a very sentimental and emotional instrument. I consider string instruments to have that quality, maybe because of their resonance they sound to me melancolic and very nostalgic. Also because of the echo it produces, i feel like the notes are like memories that stay impressed in your hears and mind for a long time after. And as a very personal instrument, we all play it in a very personal way. The strenght with which we strike the nylon strings or the metal strings varies. Our take on the music varies. I interpret this piece as a sad love song, Gadi interpreted it as a much more dynamic relationship, while Walter had a very polished and romantic sound. I also thought that there was a correlation between the way we phisically played the guitar, the way we looked while playing it, the way we sat and the way the music sounded. Also, probably fairly obvious, but i would have never known what i looked like or sounded like until i taped myselfand re-watched.

The point of this observation excercise was to look at people interact with traditional musical instruments, such as the classical guitar which is what i know best. And i always have the tendency to start from what i know best. This was helpful in trying to figure out how to make something 'musical' or some kind of instrument that made noise and how to consider the end user and his/her need.

There is an obvious need for emotion, or rather for the space to express emotion. There is a need for materials that suit the purpose of the instrument and there is a need for design. Whether we are going to take a traditional instrument and modify or we are going to create one from scratch. Either way, there is a need for playfulness, emotion and personal interpretation. So it shouldn't be too structured and stiff because things that are too structured or come with a difficult set of instructions are harder to follow and a lot less fun! (one lesson i learnt from my Red's class presentation!!!!!!)

CEREAL COMMUNICATION

The incredible SERIAL.... Took only 5-6 hours today... and then another 6 with MAX and Processing...

Here's the Serial OUT Arduino board.

SerialOUT.jpg

And here's the Ball on the screen in Processing. Took a couple of little corrections and it worked!

Here's a little little video if it.

THE EAGLE GROWS...

Now the Eagle has a new set of 'eyes'. A different ultrasonic sensor, the code in the Arduino is pretty good, i changed a few lines and now it reads straight into...

Ultrasonic.jpg

MAX/MSP!!!! This is my first patch in a really long time. Pretty basic. Takes the serial in, sets it in three ranges of distance and depending on what distance value it receives it plays a different audio file.

MaxPatch.jpg

When at the furthest (2-3 meters) it will BOMB you. When in the middle, right over the border, it will MACHINE GUN you. When really close, but not too close, POLICE SIRENS will go off.

The Eagle now is starting to speak... and it will soon have new feathers and a new house.

P-COMP MIDTERM PART 2

First we started by reviewing the Oscillator circuit using 555. Here's one that i had built a while ago.

555.jpg

Lesley and I sat down for a long time today. Now, after the melody, we have a code that allows us to manipulate sound/pitch through a potentiometer, or any variable resistors. So we played in different ways creating digital oscillators and analog ones. Getting closer to the sounds we want and more familiar with ways we can modify them.

And here's the audio from today. But be aware, it's LOUD!

MAX PROGRESS 4 MIDTERM P-COMP

So here's my progress in making a max patch for the non-traditional drum we are working on for the midterm. Some work as oscillators, making strange sounds or more drum-like. Another one makes polyphonic music, very very very nice!!!! (Thanks Leif!)

ICM LAMEST MIDTERM! THE PUMPKIN FAMILY

So, i tought and thought and thought and nothing would come out. Until i realized that today was going to be less than a week from Halloween. So, as an excercise for this class, i decided to play with enclosing the electronics in a different kind of way and using, MAX-MSP for the spooky sounds and Processing for some lame Bat-flying-around animation. But, although, lame, it took a long long time!

It was nice to work with the family on this project...

This is my husband John... thrilled to work with me...

And here's my curious cat Cindy Crawford.

And then the final product:

There is even a hole for the USB cable!!!

P-COMP MIDTERM THE RAVE-ZOOKA!!!!!!

Our drum changed shape. Now it's a Rave Bazooka. Or better, the Rave-Zooka. Despite some technical difficulty, some shorts in the circuit and our home-made gun trigger, it works and now it plays!!! Or rather, it shoots people with sound!

First step:

Home Depot was our best friend...

Found PVC pipe in the lab was part of the inspiration. It also made a lot of sense since this way people could understand where the sensor was located.
