Blog Reflections

The entire DIY process for me has been a whirlwind of different events, emotions, and learning experiences. The process came with its trials and tribulations- and there were definitely some points where I wanted to pull my hair out, or just give up. But pressure, and anxiety became my motivators alongside of course my passion for the class and the projects we pursued. This class gave me the opportunity to explore a topic of interest of mine through creative DIY blog posts, and exploration of the skill. With the making process portfolio posts I could explore the world of electronics DIY, teach myself a valuable set of skills, and bring others along for the journey. I found it therapeutic toward the end of the project to be able to write my findings down, and solidify the knowledge I had just gained in a blog post. It was also comforting to be able to reflect on each days journey, and better envision where I would go from one blog post to the next. I will always be able to look back on my making process portfolio fondly, and see my personal growth throughout the duration of the project. Although the making process portfolio was a project that carried through the entire semester, we had many other projects as a class which I thoroughly enjoyed. Projects such as the class making project, creation of a podcast, zines, book binding and more.

Each class presented something new, and allowed me to gain knowledge on a subject I had previously known little of. Such as the class period where Makerspace pioneer Lauren Britton came in and spoke to our class about the upcoming wave of cyborgs: or those who use DIY methods to modify their bodies with electronics. I was extremely grateful for the opportunity to have Mrs. Britton speak in our classroom as she is such an influential figure in the making community. When we didn’t have guests speaking in our classroom, we had to opportunity of writing short answer responses to writing prompts, and exploring and critically writing/thinking about ourselves as writers and makers. I learned the most- in my opinion- in these class periods where we tried to answer questions that seemed to not have a distinctly right or wrong answer. Such as  the prompt which addressed the question “what is writing.” The discussions that rose after we were able to write down our thoughts for a period of time I found immensely gratifying, and enjoyable. It felt like a great way to unify our class, and allow us all to share our opinions in a judgement free environment.

Along with having presenters come to us in the classroom, we made our own class field trip to the Kimmel makerspace on campus. Before the class trip I had been to the makerspace once before in order to gather information for my group’s podcast. Most of the magic of the makerspace however was introduced to me when we went the second time all together as a class. We were given a tour of the space and shown the machinery that is made available to all Syracuse University students 24/7. There were mulitple 3d printers humming at the same time, an embroidery machine tucked in the corner of the glass enclosed room, the vinyl cutter which had freshly cut stickers lain in front of it, and even a 3d machine which could produce a tangible 3d model of just about anything you could imagine. The makerspace really reignited my interest for the class, and opened my mind to the possibilities of 3d printing.

Another project that was a challenge but was also really fun was the class project. Our goal was to make something which had a rhetorical argument and we chose to make a model of the carrier dome, and highlight some of the injustices happening around the city of Syracuse and on the Syracuse campus. We used paper mache to create the top of the dome and cut the walls out of cardboard: making the intricate side details with paint. We left one side of the dome open to a figure of Otto the Orange displaying a message of the ideal Syracuse and Syracuse community relationship. On the outside of the carrier dome we placed clay figures under and outside the building being crushed by the structure, while holding little cardboard picket signs protesting the poverty, and huge social inequalities present in the city of Syracuse.

Through the combination of the activities and projects I was able to participate in within this DIY publishing course, I feel comfortable saying that participating in these activities and projects has made me a better critical writer, thinker, and maker.

Making Process Portfolio: Day 6

Project 28: Rain Drop

This project is another entertainment circuit which involves the use of a low-frequency oscillator in order to simulate the sound of a rain drop.

The components are similar to those used in the electronic cat noise, and are connected in this order.

15-48, 16-49, 23-69-72-74-91, 24-64-52, 40-108, 45-25-70, 50-63-73-71, 51-109-106, 92-105, 42-43

Project 28: Electronic Rain Drop

 

The connection between 15 and 48 connects the top terminal of the speaker, to the top left side of the transformer with a medium sized red wire.

The connection between 16 and 49 connects the bottom terminal of the speaker, to the top right side of transformer with a short white wire.

The connection from 23 to 69 to 72 to 74 to 91 connects the base terminal of the Q3 NPN transistor, to the positive terminal of a 10 micro farad capacitor, to the right terminal of the 100 micro farad capacitor, to the right terminal of the 220 micro farad capacitor, to the left terminal of a 22k resistor with two medium sized red wires and two small white wires.

The connection from 24 to 64 to 52 connects the collector terminal of the Q3 NPN transistor, to the right terminal of a 0.1 micro farad capacitor, to the bottom right terminal of the transformer with a medium sized red wire and a small white wire.

The connection between 40 and 108 connects the positive terminal of a battery, to the left terminal of the key with a medium sized red wire.

The connection from 45 to 25 to 70 connects the negative terminal of a battery, to the emitter terminal of the Q3 NPN transistor, to  the right terminal of a 10 micro farad capacitor with a medium sized blue wire and a small white wire.

The connection from 50 to 63 to 73 to 71 connects the bottom left terminal of the transformer, to the left terminal of a 0.1 micro farad capacitor, to the positive terminal of a 220 micro farad capacitor, to the positive terminal of a 100 micro farad capacitor with three small white wires.

The connection from 51 to 109 to 106 connects the bottom middle transformer terminal, to the right terminal of the key, to the middle terminal of the control with a long yellow wire and a small white wire.

The connection between 92 and 105 connects the right side of a 22k resistor, to the left terminal of the control with a medium sized red wire.

And finally the connection between 42 and 43 connects the negative terminal of a battery, to a positive terminal of a battery with a small white wire.

Once all the connections have been made upon pressing the key, the speaker creates an oscillating raindrop sound. By turning the control clockwise while holding down the key the frequency of the raindrops decreases.

To hear the raindrop noise please click here

The raindrop noise- like the electronic cat noise, uses a low frequency oscillator which is composed of the Q3 transistor, the transformer, the 100 micro farad and 220 micro farad capacitors connected in parallel, and the 0.1 micro farad and 10 micro farad capacitors in series.

Final Thoughts

What interested me about this project was the alternating oscillation of the raindrop sound. The raindrop sounds were more uneven and sporadic than consistent like the frequency of the cat noise.

Day 3: Making Process Portfolio

Today I decided to reevaluate my goal, and put some things into context. This project is an outlet for me to have fun, learn something new, and teach others how to do the same. My overall project of constructing my own synthesizer is pretty ambitious, and may take more time than this project permits.

Therefore, I am changing my initial goal and choosing to learn more about electronics, and the science of sound in general.

And when time permits, i’ll talk about how what i’ve learned applies to the creation of an analog synthesizer.

So where better to begin then understanding the concept of Ohm’s Law:

What I’ve Gathered so Far:

Ohm’s law calculates the way in which electricity flows through a circuit.

Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.

Ohm’s Law is concerned with three main aspects of the flow of electricity:

Resistance– (R) Resistance describes how hard it is for electricity to flow continuously through the diameter of the wire.It is measured in Ohms. Resistance can be a changing variable in a circuit, and more resistance can create heat within a circuit.

Voltage– (V) Voltage describes the pressure of the flow of electricity, and is measure in volts.

Current– (I) Current describes the flow of electrons through the circuit, and is measured in amps.

All of these qualities can be quantified and observed in a circuit system.

An Ohm’s Law Triangle can help conceptualize what equation to use in order to find the quantity of the chosen variable.

To find V, V= I * R

To find I, I= V / R

To find R, R=V / I

I will be going over basic schematics, and how to solve for V, I, and R using Ohm’s law.

 

About me

This is the excerpt for your very first post.

 

Hi makers!

This is blog is dedicated to following my journey in learning a new skill, and hopefully giving some advice on how you can too.

I’d like to begin this journey by introducing a little bit about myself.

My story starts in Detroit, Michigan continues in Turin, Italy and afterward in Syracuse New York. I am currently attending Syracuse University and am making this page as part of an assignment for WRT200 DIY Publishing.
