D.I.-Why??I warned you that Technograph was changing...

Welcome to our beautiful, colorful, cozy new home in The

Daily Illini! If this is yourf first time reading Technograph (which

for many of you could very well be the case), we are the sci-

ence, technology, and engineering magazine here at UIUC. We

represent all that is good and nerdy in the world, and we hope

to inspire you to let out your inner geek for some fresh air and

sunlight every once in a while.

A lot has changed over the past months here at Techno-

graph. We have a new look, home, and editorial staff. As we say,

“Goodbye!” to our old editors, however, we are only beginning

to greet the amazing effects of the changes they worked so hard

to bring about during their time here.

We are incredibly excited to be so comfortably nestled in

between these pages of The Daily Illini, and we hope that you

keep an eye out for our future releases. If you just can’t wait,

however, go to readtechno.com! We will very soon be relaunch-

ing our website with lots of all-new content of stories, photos,

and videos.

Sometimes change can be weird or different or scary, but

we are still Technograph. We are quirky and nerdy and, well,

different. We would never try to deny that. These changes are

simply embracing what Technograph has always been, deep

down, and showing it off to the world.

Thanks for stopping to read.

We live in a world of shrink wrap, bubble wrap, systems-on-

a-chip, and mass production. More things are being made by

fewer people, and the rest of us are content buying our things

pre-made. Somewhere along the way, many of us lost our will

to create. It wasn’t long ago when it was unheard of to buy a

computer ‘pre-assembled’ let alone packaged in a unibody alu-

minum casing.

However, sites like Instructables, Hack-a-day, and Make

show that there is a growing community of people with the op-

posite ideals. Many more of us are accepting that sometimes

it’s not worth it to be ‘convenient.’ Some do it for self-expression

by modifying purchased items or building them from scratch.

Others do it as an anti-consumerist statement by recycling or

reusing old parts that no longer serve their function in an at-

tempt to create less waste. However, all of them feel the same

thing: creating something with your own hands is better than

purely consuming.

This issue of Technograph focuses on the Do-It-Yourself

(DIY) projects around UIUC along with Engineering Open

House, which epitomizes the DIY spirit.

How often have you wanted your computer to

do something it simply wasn’t capable of?

A computer is a great piece of technology, but

can you use it to switch TV channels for you, keep

an eye on your thermostat, or control servomo-

tors for a robotics project? In the past, doing any

of these things would require designing a custom

circuit, programming a microcontroller (which in

itself requires expensive equipment), and interfac-

ing to your computer with even more hardware

and software. Fortunately, a cheap solution is at

hand.

The Arduino (main page: arduino.cc), which

first started to attract public attention in about

2008, is a small circuit board – about the size of a

deck of cards – that a programmer can work with

easily through a USB connection and purchase

for comparatively little. The board itself only costs

about 30 dollars, and various components or addi-

tional circuit boards can be added to give it virtual-

ly any functionality. The Arduino (the name is Ital-

ian for “strong friend”, and should be pronounced

“Hardwin”) acts as a sort of “motherboard” for a

multitude of available “daughterboards”, referred

to in the Arduino community as “shields” (due to

the way they plug into the top of the main board,

covering it up). You can easily do any one of these

tasks: control the servomotors with a “motor-

shield,” track your home’s temperature with a data

logger shield (or even a simple thermocouple), or

control your TV from your computer (or even over

the Internet, with an Ethernet shield) by simply

plugging an infrared LED into the board.

What makes the Arduino so interesting? In

short, it’s open source. Other microcontroller “de-

velopment boards,” which some students might

be familiar with from Electrical Engineering class-

es, cost hundreds or even thousands of dollars.

The Arduino costs orders of magnitude less, and

you don’t even have to buy it; all of its schematics

and code are available online, so if you have the ca-

pability of making printed circuit boards, you can

make your own. Every piece and electronic com-

ponent is available through websites like digikey.

com and mouser.com, both excellent electronics

suppliers.

One of the most useful aspects of the Arduino,

however, is its accessibility. The board was partial-

ly conceived as an aid for artists and sculptors who

wanted to create interactive art – the integration

of simple infrared or distance sensors can make a

painting or kinetic sculpture change depending

on how close to the piece the viewer stands. Such

interaction is just the beginning. The Arduino is a

kickstart to the blossoming open hardware revo-

lution – if this trend continues, open source hard-

ware will keep getting better and better. The Ar-

duino can act as the base for a GPS (pictured on

the cover, kit from adafruit.com), a microcomputer,

or an autopilot for a model plane – and it costs less

than an evening out.

A few years back, heading into college, I

had the option to get either a laptop or a desk-

top computer. Already owning an aging laptop, I

opted to build a desktop. I decided that my desk-

top wouldn’t be typical, however; it would boast

a liquid cooling system that would allow me to

overclock (or run it faster than designed).

I went into this project not knowing much

about liquid cooling systems. I did the research,

but I felt that the best way to learn was to build

the system. Building a standard computer in-

volves looking at performance charts to see how

comparable parts measure up to in similar situa-

tions. It’s also important to make sure the parts

are compatible with by checking each part’s

specifi cations. Cooling systems, on the other

hand, can either be assembled from individual

parts or come in kits with all the parts included. I

opted for a 200 dollar kit to cool both my proces-

sor and two graphics cards.

Altering the system in any way could lead to

a leak of the liquid coolant, and I was constantly

on the prowl for such events. I slowly began to

add and replace parts, working my way to an ul-

timate cooling solution. I currently have two ra-

diators, six fans, and a pond pump sitting outside

my case. I really pushed the limit of liquid cooling

by increasing the speed of my processor by 56%

and the speed of my graphics cards by 25%. After

benchmarking my system with strenuous tasks,

I found my total system performance increased

by around 40%. I have already altered the system

half a dozen times and leaked liquid into my sys-

tem twice.

Throughout the adventure, I learned

some helpful things about cooling systems:

• A single fan can barely cool a processor let

alone a CPU and two graphics cards.

• The graphics card cooling system made it dif-

fi cult to insert any other cards into the system.

All-in-all, cooling graphics cards isn’t really worth

the hassle.

• Don’t buy kits and try to fi nd parts not labeled

for computers that do the same tasks.

• There is no good way to make an internal

liquid cooling system without it being built into

the case.

• Always seal all joints with PVC cement and

regularly check for leaks.

• Liquid coolant gets dirty and computer cool-

ant is expensive.

• Don’t listen to the recommendations of any

one source. Everyone has an opinion about the

“best” way to run a liquid cooling system.

• Great air cooling beats mediocre liquid sys-

tems.

In the end, if you decide to venture into liquid

cooling, know that there will be speed bumps and

that you will make mistakes. The performance

boost over good air cooling is small, so make it

count with quality parts, proper planning, and

precautions.

Mania

Our fi rst Technocutie this issue is Anna, an Agricultural & Biological Engineering major.

She is currently working in the area of ad-vancing combustion technologies that utilize alternative fuels while improving performance, increasing effi ciency, and reducing emissions. Later on, she hopes to attend graduate school for a M.S. degree in Agricultural or Mechani-cal Engineering followed by either working in industry or continuing to earn a Ph.D. and eventually work as a professor.

Anna has many accomplishments, of course, but her favorite is how she traveled in Europe for over 6 weeks with only a back-pack. She has also worked to be an involved student by participating actively in groups in-cluding Tau Beta Pi, Alpha Epsilon, and ASABE.

Though she is not willing to share her favorite study-spot, her second-favorite is at Newman because of the comfy booths, quiet atmosphere, and possibility of seeing a friendly face. On the other hand, her favorite non-study spot is away from campus; she loves climbing trips to Jackson Falls in southern Il-linois to take her away from all of the chaos of daily life. If she must be on campus, she enjoys sitting on either the Main or South Quad.

While her greatest non-academic interest is travel, she also enjoys playing tennis, rock climbing, going out with friends, and cooking. Her favorite color is green, she can’t resist most puppies (“also the German Gray Giant rabbit is pretty hilarious”), and The Lion King still makes her tear up a bit.

I’m a bike nut. I love riding my road bike, but it’s

shiny and expensive and would just scream “STEAL

ME!” if I rode it around campus. So I decided last

summer I needed a different bike to take me from

class to class. I wanted a bike that was low-main-

tenance, looked as obnoxious as I could only previ-

ously dream of and not be appealing to steal, and not

be slow and clunky like your run-of-the-mill depart-

ment store Schwinn. So I decided to build my own

fi xed-gear bike.

A fi xed-gear bike has no shifters or gears; it stays

on one gear and only moves when you pedal (no

coasting). This is nice because there’s no drivetrain

to break and building one is much less expensive

than buying or building a typical bike.

I went on the “Chambana” Craigslist and found

someone who was selling his old Schwinn bike from

the 70’s for fi fteen dollars. I bought it and tossed out

the wheels, gears, and cranks. After sanding down

the frame of the bike, I had it powder-coated (basi-

cally a spray-on dry paint that’s really strong) neon

green, and bought some neon green wheels to ac-

company the new paint. I kept the old handlebars

but re-wrapped them in pink tape to add to the os-

tentation.

Replacing the crank (the gear the pedals are at-

tached to) was easy, and soon enough I had a brand

new set of green pedals with a pink chain on them.

Though fi xed gear bikes don’t need brakes (you can

stop by just pedaling backward) I left a sympathetic

brake on the front wheel for sudden stops that are

sometimes necessary when encountering careless

pedestrians and drivers.

I got most of my parts from 1/8 Inch. They make

a lot of “fi xie” components and are fairly cheap. I’ve

been riding my so-called ‘hipster chariot’ for a year

now and all of the components have been holding

up very well to my abuse. (Trust me, I’ve put my bike

through a lot of abuse.) The website is eighthinch.

com.

At some point in time I want to replace my sad-

dle with something that’s not a hard pleather piece

of junk. I’m also going to replace the handlebars with

something smaller, probably a bullhorn style handle-

bar set. After that I’ve basically replaced everything

besides the frame!

How do you get around campus? For many U

of I students, bikes are an ideal form of transpor-

tation for getting to class, a part-time job, or just

riding for enjoyment. They’re also a great alterna-

tive to crowded or inconvenient buses or hoofi ng

it on this admittedly enormous campus.

But what if you have a bike that’s in disre-

pair? Maybe you don’t have the tools to fi x it, or

feel that you aren’t mechanically savvy enough to

repair problems like a fl at tire, rusty chain, or bent

handlebars. For issues like these, students can

turn to The Bike Project of Urbana, a local non-

profi t organization located both downtown near

Lincoln Square and on the University of Illinois

campus in Champaign.

“It’s about building confi dence,” says Barry

Isralewitz of the Bike Project, speaking of those

with bikes in need of repair but without the tools

or know-how to do it themselves. The Bike Proj-

ect “provides a community of bikers” to help do-

it-yourself-ers of all backgrounds and skill levels

to start biking or to get back on the road after a

breakdown, according to Isralewitz.

The Bike Project provides an abundance of

services to its members to help with DIY bike

repairs, builds, and upgrades. First visits to the

repair shop are free; afterwards, patrons must join

the Bike Project co-op in order to use its services.

For students, joining the co-op costs only twenty-

fi ve dollars per year, and members have access to

all of the services provided by the Bike Project,

including the repair shop.

A lack of desirable working space can be a

major obstacle for students needing to fi x their

bikes; from cramped dorm rooms and apartments

to the oft-inclement climate of Champaign-Urba-

na, fi nding a comfortable and spacious environ-

ment to work can prove diffi cult. The Bike Project

provides an indoor workshop for repairs as well as

the right tools for the job.

For many students on a tight budget, the cost

of fi xing up a bike can prove burdensome. Un-

like many bike shops, however, the Bike Project

facilitates the DIY process, allowing students to

save themselves the cost of a mechanic’s time.

Repairing your bike yourself means you’re not

only gaining experience that may come in handy

in future repairs, you’re also keeping your ride

running smoothly while saving money. The Bike

Project has a work equity program as well to cater

to students who cannot spare the cash and may

instead work in the repair shop in payment for the

cost of membership.

Whether you ride occasionally for recreation

or depend on your bike every day to get around,

the Bike Project is defi nitely worth a visit. The

organization also has various charity programs

and community events going on all the time, so

be sure to check out their website for updates at

thebikeproject.org.

Our next Technocutie is Danny Klinger from the Electrical Engineering major (and music minor).

I’m a bike nut. I love riding my road bike, but it’s

shiny and expensive and would just scream “STEAL

ME!” if I rode it around campus. So I decided last

summer I needed a different bike to take me from

class to class. I wanted a bike that was low-main-

tenance, looked as obnoxious as I could only previ-

ously dream of and not be appealing to steal, and not

be slow and clunky like your run-of-the-mill depart-

ment store Schwinn. So I decided to build my own

fi xed-gear bike.

A fi xed-gear bike has no shifters or gears; it stays

on one gear and only moves when you pedal (no

coasting). This is nice because there’s no drivetrain

to break and building one is much less expensive

than buying or building a typical bike.

I went on the “Chambana” Craigslist and found

someone who was selling his old Schwinn bike from

the 70’s for fi fteen dollars. I bought it and tossed out

the wheels, gears, and cranks. After sanding down

the frame of the bike, I had it powder-coated (basi-

cally a spray-on dry paint that’s really strong) neon

green, and bought some neon green wheels to ac-

company the new paint. I kept the old handlebars

but re-wrapped them in pink tape to add to the os-

tentation.

Replacing the crank (the gear the pedals are at-

tached to) was easy, and soon enough I had a brand

new set of green pedals with a pink chain on them.

Though fi xed gear bikes don’t need brakes (you can

stop by just pedaling backward) I left a sympathetic

brake on the front wheel for sudden stops that are

sometimes necessary when encountering careless

pedestrians and drivers.

I got most of my parts from 1/8 Inch. They make

a lot of “fi xie” components and are fairly cheap. I’ve

been riding my so-called ‘hipster chariot’ for a year

now and all of the components have been holding

up very well to my abuse. (Trust me, I’ve put my bike

through a lot of abuse.) The website is eighthinch.

com.

At some point in time I want to replace my sad-

dle with something that’s not a hard pleather piece

of junk. I’m also going to replace the handlebars with

something smaller, probably a bullhorn style handle-

bar set. After that I’ve basically replaced everything

besides the frame!

How do you get around campus? For many U

of I students, bikes are an ideal form of transpor-

tation for getting to class, a part-time job, or just

riding for enjoyment. They’re also a great alterna-

tive to crowded or inconvenient buses or hoofi ng

it on this admittedly enormous campus.

But what if you have a bike that’s in disre-

pair? Maybe you don’t have the tools to fi x it, or

feel that you aren’t mechanically savvy enough to

repair problems like a fl at tire, rusty chain, or bent

handlebars. For issues like these, students can

turn to The Bike Project of Urbana, a local non-

profi t organization located both downtown near

Lincoln Square and on the University of Illinois

campus in Champaign.

“It’s about building confi dence,” says Barry

Isralewitz of the Bike Project, speaking of those

with bikes in need of repair but without the tools

or know-how to do it themselves. The Bike Proj-

ect “provides a community of bikers” to help do-

it-yourself-ers of all backgrounds and skill levels

to start biking or to get back on the road after a

breakdown, according to Isralewitz.

The Bike Project provides an abundance of

services to its members to help with DIY bike

repairs, builds, and upgrades. First visits to the

repair shop are free; afterwards, patrons must join

the Bike Project co-op in order to use its services.

For students, joining the co-op costs only twenty-

fi ve dollars per year, and members have access to

all of the services provided by the Bike Project,

including the repair shop.

A lack of desirable working space can be a

major obstacle for students needing to fi x their

bikes; from cramped dorm rooms and apartments

to the oft-inclement climate of Champaign-Urba-

na, fi nding a comfortable and spacious environ-

ment to work can prove diffi cult. The Bike Project

provides an indoor workshop for repairs as well as

the right tools for the job.

For many students on a tight budget, the cost

of fi xing up a bike can prove burdensome. Un-

like many bike shops, however, the Bike Project

facilitates the DIY process, allowing students to

save themselves the cost of a mechanic’s time.

Repairing your bike yourself means you’re not

only gaining experience that may come in handy

in future repairs, you’re also keeping your ride

running smoothly while saving money. The Bike

Project has a work equity program as well to cater

to students who cannot spare the cash and may

instead work in the repair shop in payment for the

cost of membership.

Whether you ride occasionally for recreation

or depend on your bike every day to get around,

the Bike Project is defi nitely worth a visit. The

organization also has various charity programs

and community events going on all the time, so

be sure to check out their website for updates at

thebikeproject.org.

Our next Technocutie is Danny Klinger from the Electrical Engineering major (and music minor).

Though he’s not sure what he wants to do in terms of a career, he will be starting a Master’s Degree in Electrical Engineering here at Illinois this fall. He is hoping to either work with circuit design or DSP in the corporate world after earning his graduate degree, or he is also considering teaching. His research interests include circuits and signal processing, and his senior thesis “deals with real-time 3-D audio techniques, using speakers and head-phones.”

Danny has accomplished quite a bit in his career here, including being a James Scholar and President of Tau Beta Pi Engineering Hon-ors Society. For fun, however, he enjoys mu-sic-related activities (either playing music or writing it) along with sports such as basketball, soccer, tennis, and golf.

When it’s time to study, Danny heads to Grainger because it forces him to concentrate. However, when he just needs to unwind, he hopes for nice weather so that he can play frisbee on the Quad.

A man who loves a classic, Danny’s favor-ite movie is Monty Python and the Holy Grail. His favorite color is blue, and he would “take cookies and milk over any dessert any day.”

Where did the time go? Winter break was just

a few weeks ago, you had all the time in the world.

Now Engineering Open House is just a week away,

and you’ve still got a project that’s nowhere close

to fi nished. The timer screensaver you download-

ed for a laugh is ticking down, mocking you – only

seven days to fi nish.

Time for some fun.

For some students, Engineering Open House

is little more than an opportunity to spend a Friday

afternoon to check out some nice exhibits on cam-

pus – the Rube Goldberg competition, the Jerry

Sanders robot matches, or a concrete-crushing

demonstration in the civil engineering lab. But ev-

ery one of those exhibits took up dozens of hours of

some student’s time, and took an even greater toll

in stress and aggravation.

So why do we do it? Why go through sleepless

nights, pouring sweat and tears (and sometimes

blood, should a screwdriver slip) into projects that

will most likely be deleted, broken down to parts,

or mothballed when the weekend is over?

In short, Engineering Open House is its own

satisfaction. There are no cash prizes (the few

awards given out are fairly standard plaques), and

that’s not what the weekend is about. Engineer-

ing Open House gives us all an opportunity to

make something cool, something that, quite pos-

sibly, hasn’t been done before, and show it to the

world. And nothing quite matches the feeling an

engineer gets when the world looks back and says,

“Hey, that’s pretty cool.”

And now...

Sometimes one of the main challenges of taking on a DIY project can be finding

the resources to complete it: workspace, tools, and/or materials. Good news, though.

Five recent UIUC post-grads are trying to change that with a place called ‘The Product

Manufactory,’ a start-up aimed at making these resources available to local businesses

and community members.

The Product Manufactory provides creative workspace and manufacturing equip-

ment. Normally, acquiring all of these amenities can be expensive, but the Manufactory

works on a concept of shared space. This way, members are able to share the space and

machinery, allowing for more resources to be made accessible at a lower cost. Member-

ship is available to both businesses and community members and can be purchased

through plans ranging from anywhere from daily to yearly use.

It also invites a more social aspect to projects as it is open to different people work-

ing on different things at the same time. The Product Manufactory hopes to create an

environment that promotes communication between groups as a way to share skills,

knowledge and ideas (or simply just to hang out). Bryan Wilcox, one of the founders of

the Product Manufactory, described it this way, “We want it to be a place where people

can come to work, and grow. It’s about professional work but doing it in a way that’s

social.”

The idea is for people, especially students, to come to the Manufactory just because

they can. It’s a place creative minds can come to find a professional community of de-

signers and engineers without classes or grades involved. The Product Manufactory is a

place for people with similar interests to work simply because they want to.

Hopes are to incorporate more interdisciplinary work, allowing engineers to work with

anyone from industrial designers to artists. This idea stemmed from the people behind the

Product Manufactory itself, which includes two engineers, two industrial designers, and a

website and software developer (and engineer). They found that when they got together, they

generated all of kinds of ideas and insights, but they had no way of implementing them. Their

hopes for the Product Manufactory are to provide a place that enables students, or others like

them, to turn their idea into a reality, whether it is low volume manufacturing, helping prepare

products as people start out on their own, or just DIY projects.

Aside from the actual shop space, the Product Manufactory also plans to host workshops,

events, and demonstrations as opportunities to not only broaden professional networks but

also to learn techniques helpful to manufacturing. This means people don’t have to be experts

to hang out at the Product Manufactory, and even though it isn’t a class, it can still be a place

to learn. As Wilcox explained, “It’s all theory until you put it into practice, and we want a place

where people can put it into practice.”

If you’d like to find out more about the Product Manufactory, there’s more about the loca-

tion, membership and what not on their website (www.TheProductManufactory.com). There’s

also a survey posted by the founders as to what you’d be looking for in a place like The Product

Manufactory. (This enables them to better serve your needs.) If you’re interested, make sure

you check it out, and get to work on that DIY!

Burn, Baby, Burn

It was a beautiful day at Engineering Open House. Thousands of visitors fl ocked to the en-gineering campus, as they do every year, to see projects, exhibits, and demonstrations. This year, however, there was one difference – the hundreds of visitors on the Bardeen Quad surrounded a rag-ing, vicious fi re.

Luckily, things were under control at the Dorm Room Fire Simulation exhibit – or so they seemed. A member of the Urbana Fire Department lit a newspaper on fi re and placed it behind a chair in the mock dorm room. Firefi ghters stood ready with hoses and other equipment; other volun-teers worked to keep the crowd back from the fi re. Within two minutes, the temperature in the room had risen to nearly 700 degrees Fahrenheit, and fl ames completely enveloped the structure as thick black smoke swirled upwards to the sky. When it seemed like the fi re was about to get out of con-trol, a fi refi ghter turned on the hose and put it out almost as quickly as it had started.

The Dorm Room Fire Simulation was a new exhibit at EOH this year, organized mainly by Dan Martin, senior in Mechanical Engineering. Martin worked with his advisor, Dr. Gavin Horn (Director of Research at the Illinois Fire Service Institute, as well as a faculty member in the Department of Mechanical Science and Engineering), to create an independent study project.

According to Dan, “The goal of this exhibit was to educate people on how dangerous fi res can be, [as well as] to demonstrate the life-saving capabilities that sprinkler systems have in com-mercial and residential use. Our fi nal goal was to educate people on Fire Protection Engineering and what engineers can do in the fi re service industry to save lives.”

One of the burn cells in the exhibit was equipped with sprinkler systems to show the life-saving effects they can have.

“Demonstrations like these along with other work done by the Fire service Institute have con-vinced universities to make it mandatory to install sprinkler systems in all dorms,” said Kevin Boron, a senior in Mechanical Engineering who was also part of the project.

The University of Illinois has spent millions to ensure the safety of its students over the past few years.

The preparation for this exhibit far exceeded that of other EOH demonstrations. “The students put in an incredible amount of time and work orga-nizing this project with EOH,” Dr. Horn said.

Martin and his team worked tirelessly to build the burn cells, acquire furniture and accessories to create an authentic dorm room set-up, install the sprinklers, transport the exhibit to the Bardeen Quad, and work with the Urbana Fire Department and the Illinois Fire Service Institute to create the presentation and ensure the safety of all specta-tors.

Before and after the cells were incinerated, the crowd was educated on the purpose of the exhibit. “The stages of fi re, fl ashover effects, and the speed in which the room becomes fully incinerated were main discussion topics during the demonstrations. We also talked about fi re safety including how to put out certain fi res, fi re extinguishers, smoke detectors, escape plans, and automatic sprinklers systems. All were discussed for awareness pur-poses,” Boron said.

Other engineering principles related to fi re safety and prevention were stressed throughout the demonstration. Heat transfer, conduction, con-

vection, and radiation, as well as their role in fi re growth, were explained to the crowd in the hopes of educating people about the realistic nature of fi res.

“I think [the exhibit] opened up people’s eyes to the destructive power of fi re. What people see on TV or in the movies about fi re and fi re safety is usually not the truth. I hope that our demonstration has inspired people to be more safety conscious in their everyday lives, and make emergency plans for themselves and their families in case of a real fi re,” Martin said.

There’s no doubt that if the Dorm Room Fire Simulation continues to make an appearance at Engineering Open House, it will draw crowds comparable to that of the concrete crusher and the Jerry Sanders competition. In the future, other aspects of fi re prevention, those specifi cally ad-dressing structural engineering concepts, could be stressed. Dr. Horn said he believes that more could be done with temperature displays and a greater emphasis on fi re protecting engineering.

“There are so many different ways in which engineering helps us understand the fi re phenom-enon and in which engineering is helping us to build safer buildings that we could put together new themes for many years to come,” he said.

There were dozens of exhibits in seventeen buildings scattered across the Engineering Quad and beyond. One of the most surprising exhibits, however, was located on the second fl oor of the Mechanical Engineering Lab on the east side of the North Quad. Stationed here was Illini Prosthetic Technologies (IPT), and members were informing passersby of their important mission that began here at the University of Illinois.

IPT is a non-profi t student organization that specializes in prosthet-ics for forearm amputees who still need to work. There are nearly 25 million amputees worldwide, 80% of which live in developing nations. Currently, they are working on adjustable, rapid fi tting sockets for a uni-versal prosthetic that could be adjusted for the length and diameter that the user might require.

Custom fabricated prosthetics are the existing traditional methods of production and are made by creating a mold (which can take several days to cast and outfi t) around the still existing form of the arm. The disadvantage to this traditional method is the gap of time between the limb being amputated and the prosthetic being fi t, as muscle atrophy (the deterioration of muscles not in use) begins to take place immedi-ately after the medical procedure.

Director of Product Development and Mechanical Engineering stu-dent, Ehsan Noursalehi, when asked about prototype modeling and the model variations on display, said, “…it was defi nitely a learning pro-cess. We wanted the strength of some bulkier prototypes with the fl ex-ibility and usability of others.”

This is what Engineering Open House is all about: inspiring others to participate in their own education while making a noticeable impact on the world.

At Engineering Open House, an interesting substance

known as oobleck made its appearance at the ‘Freaky Non-

Newtonian Fluids’ exhibit operated by Keramos, the Ma-

terial Science Honor Society. Oobleck is a non-Newtonian

fl uid created by combining corn starch and water, normally

in a 1:2 ratio. Calling oobleck a non-Newtonian fl uid is all

fi ne and dandy, but what exactly does that mean?

Generally, fl uids are classifi ed as Newtonian when their

relationship between viscosity and sheering is linear with a

constant known as the coeffi cient of viscosity. This basically

means that how thick or fl uid something is is related to how

quickly you can move through it. For example, consider try-

ing to swim through two pools, one full of maple syrup and

the other full of water. Maple syrup is a lot more viscous

than water, which means it’s also going to be a lot harder

to swim through.

Non-Newtonian fl uids don’t have this linear relation-

ship between viscosity and sheering; they tend to have ex-

ponential or quadratic relationships instead, which means

they can act more solid or less solid as you apply force to

them. In the Keramos exhibit, they demonstrated one sub-

class of Non-Newtonian fl uids: sheer thickening fl uids, or

dilatants.

Non-Newtonian Fluids

Oobleck is an example of a sheer thickening

non-Newtonian fluid. When one applies force to

this type of non-Newtonian fluid, the stress that

the force introduces causes the fluid to become

nearly solid. In the case of oobleck, try punch-

ing it and your hand will just bounce off, but try

softly laying your hand on the surface and it will

sink through to the bottom. Eventually visitors at

the exhibit discovered they could even pack it to-

gether like a snowball and toss it quickly back and

forth, but if they didn’t catch it in time or let it sit

in their hands, it slipped through their fingers like

a liquid.

Sheer thickening non-Newtonian fluids have

some potential real-life applications, most appar-

ent in situations involving impacts. As mentioned

before, they are fairly flexible but when a sudden

force is applied they act very solid. This character-

istic could potentially be used in applications such

as sports equipment or protective wear where

users desire flexibility but also require protection

upon impact.

One of the things that made the exhibit so

entertaining was the amount of participation.

Visitors, adults and children alike, continuously

gathered at the exhibit, despite the fact that the

demonstration tends to be a popular experiment in

classes as low as grade school. Keramos had two

large tubs of the gooey stuff and there was always

someone with their hands in it, be it a MatSE stu-

dent or an EOH visitor.

As Kyle Lamson, Keramos member and sopho-

more in Material Science, said, “We wanted our

exhibit to be as interesting as possible while also

being educational. This allows people to get a

thoroughly hands on feeling to what non-Newto-

nian fluids do.”

Whatever their reasoning, it worked. Not only

was the exhibit entertaining and engaging, but it

was took second place for “Just for the Fun of It:

Hands on Learning,” an award given by EOH. The

best part, though, is the fact that now some of us

know a little bit more about non-Newtonian fluids

too.
