Sketching with Hardware 2013

Auch im letzten Sommersemester durfte das Blockpraktikum „Sketching with Hardware“ nicht fehlen. Zwölf Studierende tauchten ein in die Welt der Elektronik und bauten sechs tolle interaktive Prototypen. An dieser Stelle finden Sie eine Zusammenfassung der Projekte. Sollten Sie sich für das Praktikum selbst oder ausführliche Projektbeschreibungen interessieren, besuchen Sie das eigene Blog von Sketching with Hardware.

Das Thema in diesem Jahr war „Reduce, Reuse, Recycle“ und eigentlich ziemlich simpel: Nimm dir etwas völlig Unbrauchbares, Altes und Kaputtes und verwandle es ein etwas völlig Neues und Zweckentfremdetes. Haben wir Ihr Interesse geweckt? Dann auf zu den Projekten:

The Real Dropbox

The Real Dropbox is a interactive scanning device directly connected to the users dropbox account. Initially the concept suggested further functionality such as implementing the ability to make phone calls using a skype account and a earphone. The goal was to produce something out of an idea, that could indeed be useful to someone. Even if it was only ourselves.

DJ Teddy

Fulfilling this year’s topic „Reuse, Reduce, Recycle“ we searched for some old, used stuff and found three things: An old teddy to reuse, a shopworn MP3-Player to recycle and finally (to reduce the amount of junk in our homes ;-)) an unused step machine, but what to do with those parts? Our first thoughts were „everybody likes music, everybody loves teddies and of course everybody would go crazy seeing his teddy dancing to his favourite music while motivating him with a step machine”. So our idea was born, a music playing teddy or as we named it: „DJ Teddy“. Some additional special effects should allow it to become the perfect entertainer on every party. In the end the final result surprised us and I promise, it will surprise you, too.

Melody Bakery

This project, „Melody Bakery“, was made from an old toaster. We equipped it with an Arduino Mega, took advantage of the toaster’s convenient, useful physique and transformed it into something totally different with completely new functionalities: A MIDI sequencer loop station, aka. „Melody Bakery“. This device can read a set of eight notes, making up two four-four times at the range of seven notes adding up to one whole octave. Furthermore, you can feed the toaster with a set of an instrument which the notes are to be played with and a background beat to make the produced music loop more enjoyable and usable for playing along with e.g. the bass or the guitar. The notes, instrument, and background loop can then be sent to an audio program on a connected PC.

Gameboy 0.5 beta

First of all, we needed something to work with. It was pretty clear that it would be most fun to take an old thing – whatever it would be – and make it behave in an unusual way. Luckily, we found this at a flea market: It says oscilloscope on it and was once used in medicine for graphing the human pulse. The oscilloscope consists of two main parts, the left side holding a revolving paper roll, a spring and mechanics to move the paper stripe. „Gameboy 0.5 beta“ – our idea of how gaming might have looked 100 years ago. We built an arcade game for the advanced. You don’t play one level, you play two. At the same time. With a joystick. The two needles are arranged vertically, so the game is split into an upper level and a lower level. The upper level is always the same, collect the golden coins by going over them and loose one each time you crash into a wall. The y-axis if the joystick directly maps to the position of the needle.

Walkman Remote

The idea we have chosen for our project started with a walkman: many of us have one at home and it is hard to throw it away, because it often has good childhood memories attached to it. On the other side a walkman has all controls that are needed to control a music player (Play/Pause, Next/Previous Song, etc.) so our plan was set: let’s build a remote for your computer’s music player that is inside an old walkman. It should contain all the basic functions needed for that: play/pause a song, switch between songs and adjust the volume.

The Workout Orb

The Workout Orb (formerly: Weather Orb Muscle Cool Trainer) is a device that allows you to keep track of the progress in your workout (such as lifting weights) as well as to improve its quality. It consists of a wristband worn near the elbow that measures the rotation and muscle activity of ones arm. It then sends this data to the Arduino and thus triggers the feedback in the second component, the actual orb. This component cosists of a translucent orb that is filled with water, which, when turned on, is nebulized to form mist. It is then illuminated by LEDs to give visual feedback. The orb also harbors a small piezo element that additionally allows feedback in the form of sounds an melodies.

Sketching with Hardware 2012 6/6 – GPS Box

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 6, GPS Box! Have fun 🙂

When thinking of outdoors, one of the first things that came into our minds was GPS. We use it nearly constantly in our everyday activities – from locating your own position to finding the right directions to your goal. From this concept an idea started to form, and soon the GPS box was born.

What is it?

A box with a secret locked inside. The only way to reveal it is to bring the box to a specific location. Only then will the box open and allow you to access its contents.

The box lid is equipped with a distance meter (here the four LEDS), a needle and has a compass rose engraved on it. Once the box closes, the needle spins on itself and finally stops to point at the direction of the goal. As you walk, the less blink or turn off to signal when you are getting closer.

Overall, it is a very versatile object that can be put to several uses. One of them would be to use it for a sort of „inverses geocaching“, only instead of having to find a certain object, you have to bring the object to the location. Once you reach the destination, you can let to world know of your success, and then re-program the GPS coordinates for the next person to take up the challenge.

Sketching with Hardware 2012 5/6 – PEO – Personal Energy Orb

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 5, PEO – Personal Energy Orb! Have fun 🙂

PEO is a little energy device that limits your computer usage time to a value generated from the distance you traveled with your bicycle in advance. It raises awareness for the amount of time spent in front of computers nowadays and forces its users to seek physical exercise in compensation for their „screen hours“.

The Idea

the concept poster

The excessive use of computers is a common problem in todays connected world. Many jobs require the use of personal computers throughout the work day and also our spare time is frequently spent at home in front of computers or similar technical devices, whereas our time spent on physical activities decreases. This can lead to a lack of social interaction and can ultimately cause health problems.

While it is not possible to simply reduce the time of computer use for anyone, e.g. computer scientists, a way of mitigating this problem is to find the right balance between computer use and physical exercise. However, as is generally known, regular sportive activities require a certain level of self-control, therefore our idea was to create something that supports people with keeping that balance between computer use and being outside and doing sports.

Sketching with Hardware 2012 4/6 – Energy Fight

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 4, Energy Fight! Have fun 🙂

Energy Awareness

Nowadays fossile energy sources are exploited to the farthest extent and the need for alternative ways of energy production is urgent. The awareness of new and clean forms of energy is an important issue, that already the youngest members of our society should be given an understanding of. This is why we have developed a concept of achieving a higher energy awareness for children in a playful manner.

   

What is it?

Enery Fight is a game that increases energy awareness. It illustrates different possibilities to produce energy. The produced energy is used to manipulate the game board, which is a circle shaped acrylic glass panel, placed on top of the Engergy Fight box. To start the game you place a small ball in the centre of the board.

The two players battle each other by producing energy on the four sides of the box to get the ball into the hole on their side of the game board. The two ways to produce energy are wind, created by blowing into a wind wheel, and motion energy, by cranking a wooden wheel on the side of the box.

Sketching with Hardware 2012 3/6 – Environmental Jukebox

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 3, Environmental Jukebox! Have fun 🙂

Environmental awareness

As long as anyone can remember our environment has been providing food, water and a space to live for all of us. However our behavior changed and nowadays the environment also is a very important energy supplier. With our project, called the EnvironmentalJukebox, we wanted to make people aware that our environment has capabilities we haven’t ever thought of. It can be used to be creative. Especially aspects referring weather can be used to control a machine we have created. Since music plays a big role in many people’s lives we thought it could be very interesting to connect music and environmental aspects. This is how our project emerged.

What is it?

The EnvironmentalJukebox is, as its name implies, some kind of jukebox. However it’s not a common one. Instead of letting the user choose a certain type of music or radio station, the EnvironmentalJukebox creates and changes music by itself based on four environmental parameters: wind, light, rain and temperature. This music consists of piano-chords and a drum-beat. Once one or more of the environmental parameters change, music changes accordingly. For example, if the speed of the wind increases, the speed of the music increases. If it begins to rain, music gets louder. Temperature is used to decide whether chords within a minor or major key should be played and the amount of light is crucial for the pitch of the tones. The more light is captured the higher is the pitch of the tones and chords.

Sketching with Hardware 2012 2/6 – W.A.M.P

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 2, W.A.M.P- Where are my People? Have fun 🙂

What is it?

This years topics for the sketching with hardware course dealt with outdoor experiences. We chose the subtopic “distance” for our Prototype.

Two thoughts lead to this idea:

Korbinian experienced a situation, in which he had a partynight with a friend, whose wife tried to track his position via his smartphone and was worried, as the signal showed a place on a lawn.
Thomas on the other hand, thought of an utopic tool, which would be able to find the position of anything you are looking for and showing the spot with an interactive flying arrow in the sky.
Also the Idea was concepted for couples. Recently being in love with somebody makes you think of that person all the time. What is she/he doing? Where is she/he at the moment? The WAMP is a concept to fix the physical gap between two people by displaying the position of the partner, which could satisfy the emotional need of being close.
Pretty soon we made up our mind to use a weather vane to show a person´s position. Its normal task is to show the direction of blowing winds and cardinal directions. The WAMP shows where you will find your girl- or boyfriend or other people you are tracking via their smartphone or computer. It is designed as a decorative wind vane with special features, standing on your balcony or terrace.

A simple sketch we made for the prototype while planning:

Sketching with Hardware 2012 1/6 – TeamTwist

In August, our workshop “Sketching with Hardware” took place for the 6th time. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Outdoor Electronics”. Again, at the final presentation the crowd had the chance to experience six extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 1, TeamTwist! Have fun 🙂

We all know how to open a box, but what if the box doesn’t want to be opened?

You are geocaching and found the cache. It’s slightly open but every time you get close, the mysterious chest locks itself. As you look around you see some strange objects blinking. Soon you notice that each object is reacting with your moves but there are far too many objects to activate all of them at the same time on your own. So if you don’t have a partner with you, go home or look for one, because you are playing TeamTwist.

What is it?

When playing TeamTwist you have to interact with the strange objects, called widgets. To finally open the chest, you have to activate different widgets depending on the current level. After each level the chest opens itself a little bit further.

After twisting yourself more and more from level to level, the chest is finally willing to let you raise its treasure.

How does it work?

The game consists of the chest and several widgets.

The chest

In an old sparkling wine box in we placed two servos: One for lifting the lid and the other to lock the box. Our first prototype (as you see in the video) was just a shoe box. Furthermore the box is secured by a light barrier (ultrasonic sensor) which prevents people to approach it before the end of the game.

Sketching with Hardware 5/5: Glowworm Love

In March, we celebrated the 5th anniversary of our workshop “Sketching with Hardware”. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Bionics”. Again, at the final presentation the crowd had the chance to experience five extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 5, Glowworm Love!

What is it?

„Glowworm Love“ is an ambient room light, consisting of 4 individually colored artificial glowworms. These worms can be combined by bringing two glowworm bodies together. If they like each other, they will mix their color and produce a new color. They will keep this new color even after splitting them again.

This way the user can produce many different colors and create different moods within the room by playfully combining the glowworm lights.

Sketching with Hardware 4/5: Blowfish

In March, we celebrated the 5th anniversary of our workshop “Sketching with Hardware”. In 7 days, 12 students learnt to use electronic components, to create new creative user interactions and realized their own physical computing projects. The overarching topic for this course was ”Bionics”. Again, at the final presentation the crowd had the chance to experience five extraordinary experience prototypes. During the following days, all projects will be presented on this blog. Today: Part 4, Blowfish!

What is it?

This years theme in „Sketching with Hardware“ was Bionics. Consequently, the task was to rebuild or reuse a natural and biological method. Our team decided to imitate the behavior of Tetraodontidae – that’s the family of fish with the ability to inflate their body to a ball-like shape in order to defend itself. In an outburst of pure creativity, we named our prototype Blowfish!

Blowfish is designed to puff up when users come too close or are too loud. Somebody clapping hands loudly will find Blowfish doubling its surface. As puffers don’t like people coming too close, Blowfish inflates if one approaches it’s face.

To put it in a nutshell, Blowfish is an ambient display visualizing noise and distance in a striking way. Just put it in one of your room’s corner and you’ll always know whether or not your shouts about an exiting soccer game will disturb your neighbors.

Sketching with Hardware 3/5: FrettyFlytrap

What is FrettyFlytrap?

Natural model for FrettyFlytrap is the venus flytrap, a carnivorous plant that is domiciled in a narrowly restricted spread-area in the USA. It catches and digests animal prey – mostly insects. Its trapping structure is formed by the terminal portion of each of the plant’s leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike.

In contrast to the real flytrap, FrettyFlytrap isn’t just a plant that has primitive needs like food, but also has some human-like feelings: it seeks for love and fondness, and if it gets no food or if it is provoked, it probably shows its angry side.

How can FrettyFlytrap express its feelings? For the one thing, LEDs on the top of the plant’s head show its mood. Red LEDs signalize a critical state, green LEDs show that the plant is satisfied. A further indication is given by the plant’s mouth: If it is open, the plant is hungry and thus impatient or was recently provoked by being touched at its teeth. If you want to treat FrettyFlytrap well, you can tickle it under the chin, and you will see that FrettyFlytrap rotates its leaf, which is a sure sign that it enjoys your treatment.
