1. Evolution Simulation
TEAM (the names of all team members): Morris, Stefan
DESCRIPTION: A simulation of a world with creatures. 
The world is a 2D screen.
A creature is a polygon.

All edges of a polygon have equal length.
Polygons can be born into the world. 
Gaps between Polygons could be new Mutations of formerly unknown Polygons.

"Natural" Selection is defined by rules.
Polygons can not overlap. Only vertices and edges can overlap.
Polygons with more neighbors are healthier than polygons with only a few neighbors.
Vertices with a small angle sum are not as healty as 360° Vertices.
Polygons with only the same neighbors are not as healthy as polygons with many different neighbors.
Polygons can be convex or concave.
The edges of a polygon do not overlap. Only adjacent Edges overlap at one Vertex.
All vertices of polygons have different positions.
Vertices of one polygon can only lie at the end of exactly two edges.

2. Powerwalking power: creates energy from walking
TEAM (the names of all team members): Doro, Marja, Joram, Manuel
DESCRIPTION:
    We want to gather excess energy from walking or running. We constructed three different linear alternators that all move a magnet through a tightly wound copper coil. A LED is powered by the linear alternator and flashes up when shaking the device. When attached to a runner the LEDs light up with every step. The design is simple, and the parts can be salvaged from other devices. The tubes in one of the hacks are made from rolled up paper and the end caps are made from wood. Another tube was salvaged from an old electrical installation tube. The coils were wound by attaching the tube to a battery powered drill and slowly rolling up the copper wire. Total cost of one build is somewhere between 5 and 10 EUR for the copper wire and the magnet. Reclaim the wire from an old coil will reduce the costs even further. 
    With some further iteration we believe that it could be possible to charge a battery while running, effectively providing an off-grid sustainable power source for small scale applications.
    This little hack is great to build your own running light at low cost by reclaiming materials you might already find on your fridge (magnets) or in an old printer (coils). The key for an efficient system is a strong magnet and a narrow but tightly wound coil with as many turns as possible.

3. total recall nails
TEAM (the names of all team members): DARSHA HEWITT, DENNY PHANE, NADJA BUTTENDORF
DESCRIPTION: let's make fiction science again! In the Sci-fi movie 'Total Recall' from 1990 the secretary changes the color of her fingernails by tipping on her nails.OMG!
 We experiment with an universal indicator paper, a ph-indicator to test materials for acidity, you can buy in every pharmacy. The colours from yellow to red (1-6) indicate an acidic solution, colours light blue to dark blue indicate bases (9-11) and green colour indicates that a solution is neutral.With a superalkaline solution we changed the color of the paper from yellow to blue.We found a way to RECALL the previous yellow color by dropping some superacidic solution on the paper.
No LED's involved!

We also invented the PISS NAILS! 
A very healthy tool to test the pH of your urin and check if your hyperacidity.

4. augmented cooking bot
TEAM (the names of all team members): 
Arne Jenssen
Sascha Held
Georg Buchner
Markus Scheider
Tim Baeumlisberger
Moritz Ebeling-Rump
DESCRIPTION:
The augmented cooking bot attempts to solve the problem of overcooking and undercooking of food. We use temperature sensors and feed that into an algorithm that tells you when to flip the pancake and when it is done and it also manipulates the temperature of the oven by turning it on/off. 
We have done a lot of experiments with

    Final version of source code, also distributed von https://github.com/alamar808/pancake
    
/*
 * Inputs ADC Value from Thermistor and outputs Temperature in Celsius
 *  requires: include <math.h>
 * Utilizes the Steinhart-Hart Thermistor Equation:
 *    Temperature in Kelvin = 1 / {A + B[ln(R)] + C[ln(R)]3}
 *    where A = 0.001129148, B = 0.000234125 and C = 8.76741E-08
 *
 * These coefficients seem to work fairly universally, which is a bit of a
 * surprise.
 *
 * Schematic:
 *   [Ground] -- [10k-pad-resistor] -- | -- [thermistor] --[Vcc (5 or 3.3v)]
 *                                               |
 *                                          Analog Pin 0
 *
 * In case it isn't obvious (as it wasn't to me until I thought about it), the analog ports
 * measure the voltage between 0v -> Vcc which for an Arduino is a nominal 5v, but for (say)
 * a JeeNode, is a nominal 3.3v.
 *
 * The resistance calculation uses the ratio of the two resistors, so the voltage
 * specified above is really only required for the debugging that is commented out below
 *
 * Resistance = PadResistor * (1024/ADC -1)  
 *
 * I have used this successfully with some CH Pipe Sensors (http://www.atcsemitec.co.uk/pdfdocs/ch.pdf)
 * which be obtained from http://www.rapidonline.co.uk.

DESCRIPTION:
This project addresses the field of affective sciences in humans and animals. We are interested in the way the mankind extrapolates human centered academic terminology (E.g. from psycology) to the natural world. We wanted to illustrate this by linking the output of face/emotion recognition software to sounds made by animals experiencing an "equivalent" emotion. A very basic example would be the trigger of an angry dog sound when the camera detects an angry human face. We built a strong multidisciplinary team comprised of specialists on many fields ranging from programming to arts and science. We used commercial software already available for face and emotion recognition and adapted it to our needs with the use of programming and hacking. In regard to the sounds, they were obtained from scientific studies done by researchers while studying "animal emotions" in the lab and the field.  The final hack hallmarks an interactive activity showcasing scientifically relevant data and state of the art  technologies.

7. infection Interaction game
TEAM (the names of all team members): Hélène Trommelen (helenetrommelen@gmail.com), Gene Kogan 
DESCRIPTION: 
For this project, a small interactive game was created  in which the user can get acquainted with some of the concepts of infections, such as the risks,symptoms and ways to prevent it. The format of a game is much more interactive compared to a textual format of a traditional information folder. Including gamification in the format imposes incentives to engage in the consumption of information. By creating a tool that adresses the understanding of their situation it can serve as a tool for creating an empathy path between the docter and patient perspective. In that way, it can serve as an affective mode of understanding. Positive reinforcement through gamification and role play empowers patients to embrace a challenge and become a participant rather than a wittness in the fight against disease.
The goal is to 1. make patients introduce patientsto these concepts in an accessible way 2. Make them feel comfortable with thedisease perspective 3. Create curiosity to participate in the treatment by creating an empathy path betwen the patient and the physician. 4.Motivate them to ask questions.

8. battery plant-pots
TEAM: 

DESCRIPTION: Some bacteria, found in mud from your local lake, can produce electricity, by eating sugars or organic acids, and anaerobically donating their terminal metabolic electrons to an electrode exposed to air. In simpler terms, if we physically separate these bacteria from the air, but connect them to it via a pice of wire with resistance, we'll get voltage and current, i.e. electrical power. The plant added to the system will supply the sugars via its roots.

Duplicates of two different prototypes were created: 
    1. Carbon-epoxy electrodes
    2. Graphite-carbon-epoxy electrodes
    
    Procedure
    1. Carbon epoxy electrodes:
        -  activated Carbon granulate was pounded into powder using the back of a screw driver in a glass bowl
        - The activated carbon powder was mixed with power mix metal 5-min epoxy (Patex) to obtain a metallic-looking black paste
        -The epoxy-carbon paste was shaped using gloves fingers into a flat shape, and the crocodile end of a two-crocodile wire was stuck into it. 
        - when the epoxy hardened, the contact was buried in 2cm of activated carbon granulate in the bottom of a used 2L plastic bottle, which was previously washed with liquid soap and tap water.
        - The activated carbon later was covered with tap water
        -Mud collected at a depth of ca. 10-20 cm at the water edge of lake Teufelsee 6 days ago and stored at 5C since, was placed over the activated carbon and also covered with water. 
        - a devil's ivy cutting, which was placed for a month in water and grew a little root was held upright in the bottle above the mud
        -about 5 cm of aquarium gravel was added to the bottle around the plant stem and covered with water
        -activated carbon granulate was added above the gravel, and a crocodile in carbon-epoxy as above was stuck in it
        -an activated carbon sponge was used as a top, and covered with water.
        - The top and bottom electrodes were connected using the few crocodile, via a 1kOhm resistor.
        Duplicates names: Rosa Luxemburg and Karl Marx
        
        2. Graphite-carbon-epoxy electrodes
        - The construction was similar, but this time, ø 0.7 mm graphite pencil filings were used to augment the electrodes, by aligning five in parallel and one across, which stuck to the parallel ones using carbon-epoxy. A crocodile was attached to one side of it using carbon-epoxy.
        - The graphite supports were buried in the activated carbon granulated at the bottom and top of the plant pots.
        -all the rest of the construction details were similar
        Duplicate names: Rosa Parks and Karl Liebknecht
        
        Results:
            25/9/16
            Marx 0.4mV
            Luxemburg 0mV
            Liebknecht 3mV 
            Parks 13

9. quantum reality / virtual reality
TEAM (the names of all team members):Benjamin Skirlo, Giulia paparo, Johanna Jaskowska, Philip Silva, Thomas Heidtmann
DESCRIPTION: Experience Quantum Physics through Virtual Reality. One doesn't directly see quantum mechanic effects but using VR it's now possible! We visualize the electron probability density and thus the possible states in the hydrogen atom through funny objects. The idea is that an observer would then trigger that a certain state is chosen.

TEAM (the names of all team members):
@teoguso- math maker
@meredityman- fearless cheerleader
@sveinb- radio mercenary
@nolash- enigmatic VR prophet
@xmunoz- software wench 

DESCRIPTION:

We scrapped together a passive radar collection system using 2 TV tuners with anntenae, a USB hub, and some custom software. The amount of data that these tuners collected proved to be much more than we could process as mere mortals, but we did make a valient attempt to implement a custom cross correlation function to deduce the dopplar shift and distance of radar contacts, before eventually settling on using some built-in octave methods. We were also able to produce a proof of concept for transmitting finished radar matrix vertices to Unity binary via socket. More information about the tools that were used and source code and be found in our github repository, linked below.

TEAM (the names of all team members): Rachel, Kati, Rick and an honorary mention to Denny from the nail club for future ladies.
DESCRIPTION:  We wanted to produce an artistic visualisation of the salt content of various bodily fluids. Does salt concentration change during the day? How does it compare between saliva, blood, sweat, tears and urine? With our machine you can measure it yourself at home and produce an image on cyanotype papers. Electrodes are introduced in a liquid sample and the salt concentration controls the aperture over the photopaper. The paper is exposed to light and the resulting size of the image reflects the salt concentration!

TITLE: Humans Sound Like Apes

TEAM WE ARE HERE:  http://pad.okfn.org/p/Humans_Sound_Like_Apes


DESCRIPTION: I would like to link/hack the output of human face/emotion recognition software to sounds made by animals and present it to the curatorial team of the STATE Festival (On Emotions) in order to showcase it at the at the Natur Kunde Museum Berlin on the evening of the 3.11.16 . The idea is to hear an angry dog or ape when the camera detects an angry face. Such software already exists but only provides text as output (E.g. "happy", "sad", "angry", etc). In regard to the sounds, they could be obtained from scientific studies done by researchers while studying "animal emotions" in the lab.  The final hack should be able to produce a continous animal soundtrack (maybe on loop?) that can be mixed by a DJ and played during the ceremoy. This will create an interesting interactive activity between the audience and the location by embracing the theme of the festival.
EQUIPMENT/SKILLS/PEOPLE NEEDED: Computer with camera and speakers, programmers, DJ.

TITLE: open science outreach booklet (or FAQ flyer)
DESCRIPTION: This is a proposal for a write-a-thon to compose a brochure (or flyer) telling people about how any science should be open science. In particular, we should emphasise how doing science should be like free (as in freedom) software, where all output should give everyone the freedom to use it for any purpose, study it, build upon it, and share the results.

We need to clearly define "open science" for the purposes of this brochure, answer common questions/concerns, and address common misconceptions. It will also be helpful to give concrete examples on what a fully "open science" research workflow looks like with suggestions on how both professional and non-professional scientists can do open science.
EQUIPMENT/SKILLS/PEOPLE NEEDED:
* computers to type on
* computers with graphic design and pagesetting software such as Inkscape or Scribus
* printers if proofs of the flyer/brochure are printed

TITLE: DIY motion sensing "camera trap"
DESCRIPTION: Motion sensing "camera traps" are used for monitoring wildlife by taking pictures of them when the cameras are triggered by their motion.

Current off the shelf camera traps are not only expensive (easily hundreds of Euros for a good one), but are also highly proprietary black boxes where you do not have the freedom to study them, build on the design and share it with others.

Technarium has made amazing progress on developing a DIY camera trap and this proposal is to build on that momentum and develop a hackable DIY camera trap where the design/schematics are released under a free culture (as in freedom) compatible license.

It is also important that the product is relatively cheap to make so that it can be more financially accessible.

EQUIPMENT/SKILLS/PEOPLE NEEDED: A basic camera trap would require:
* camera unit with night vision
* motion sensor such as a passive infrared (PIR) sensor
* realtime clock (RTC) to timestamp photos
* infrared flash for night time pictures
* long battery life (more than a month!!)
* rugged weatherproof case because it has to be deployed in the wilderness (or your garden)
* relatively cheap and easy to assemble so students can build them in class

material:

* computers for coding and CAD
* parts such as different camera units, motions sensors, realtime clocks, power supply parts, etc.
* probably microcontroller boards such as Arduinos
* soldering tools???

TITLE: Evolution tracing game app
DESCRIPTION: The BBC once did a science outreach activity:

http://m.wimp.com/attempting-to-demonstrate-evolution-with-a-line/

In this activity, you show a straight line on a computer (or tablet) screen and ask a person to trace over it (with a pen or just the mouse). You make the original layer (with the perfectly straight line) invisible and ask a second person to trace over the first person's line, and continue the process ad infinitum. At the end, you show all participants the "evolution" of the line. You wil see that each subsequent copy of the line is a little bit different from the previous one, and that's how evolution works!

My proposal is the development of a cross platform educational app that does this with customisation options. For example, you can specify whether you want to start with a straight line or another arbritrary shape (so likely some basic vector graphics capability). After letting lots of people trace over the lines, the app will ideally offer different ways to visualise the evolution. I'd also love to ability to start different lineages, so for example at a certain point you can choose the split the lineage and see how the evolution diverges.

TITLE: Polygon Evolution
DESCRIPTION: A simulation of a world with creatures. 
The world is a 2D screen. The limiting ressource is space.
A creature is a polygon. Each edge of a polygon has the same length.
Polygons can be born. Und which condition will a polygon be born? Which location? Which orientation? Does it float like a bacteria or is it already joined to a parent like a plant.
Polygons can die. Under which conditions? Does it have a live counter lika a candle? Or does it just have a certain probabiliy?
Will the simulation software deterministic or random?
Polygons can have mutated children.
Mutations could be one edge more or less. Different angles.
Polygons have a live time.
"Natural" Selection is defined by rules.
Polygons can not overlap. Only vertices and edges can overlap.
Polygons with more neighbors are healthier than polygons with only a few neighbors.
Vertices with a small angle sum not as healty as 360° Vertices.
Polygons with only the same neighbors are not as healthy as polygons with many different neighbors.
This hopefully avoids mono cultures.
Polygons can be convex or concave.
The edges of a polygon do not overlap. Only adjacent Edges overlap at one Vertex.
All vertices of polygons have different positions. Vertices of one polygon can only lie at the end of exactly two edges.

How does the world look at the beginning?
 empty, one shape ("Adam"), a few shape, lots of random shapes
 Plant like or bacteria like bahaviour?
 
Only polygons with rational angles are considered for now.
An angle is a fraction of a full circle.
The angle of a full circle would be: 1/1
The angle of a square would be 1/4
The angle of a regular n-gon would be 1/2 - 1/n

Data structures:
    Angle:
        nominator: Int
        divider: Int
        func value() -> Double
        func degrees() -> Double
        func radians() -> Double

TITLE:Plant-pot battery (plant-MFC)
DESCRIPTION: Some bacteria, found in mud from your local lake, can produce electricity, by eating sugars or organic acids, and anaerobically donating their terminal metabolic electrons to an electrode exposed to air. In simpler terms, if we physically separate these bacteria from the air, but connect them to it via a pice of wire with resistance, we'll get voltage and current, i.e. electrical power. The plant added to the system will supply the sugars via its roots.

TITLE: Augmented Cooking Bot
DESCRIPTION: I propose to use an infrared camera to hack the experience of cooking food to prevent it from overcooking or undercooking. By use of remote IR temperature sensor I imagine to use machine learning to find the optimum heat setting of the oven and cooking time. 
EQUIPMENT NEEDED: We need a infrared camera that can stream temperature data continuously and cooking equipment (portable induction oven?). I am flying in from Norway, so i can’t bring this equipment my self. 
SKILLS/PEOPLE NEEDED:
- I know programming and some machine learning, I have some ideas about algorithms to look into, but it would be nice to have more ML hackers
- chemists 
- people interested in cooking in general, 
- people who are interested in science of cooking

TITLE: The infection risk game
DESCRIPTION:  
I would like to work on a game for interactive health communication. My idea was to have the patient interact with falling balls that describe either infection symptoms (blood in urine), or preventive measures (drink water). Similar to something like this: http://www.openprocessing.org/sketch/215712 . My idea was that, when the player catches a symptom, the ball sticks to the player and he has to shake it off by warning the doctor. There would also be some kind of scoring system. The goal is not necessarily that the patients learn all the symptoms/preventive measures, but more to familiarise them with the concepts by interacting with the information. This was my idea, but I'm open to other input as well.

TITLE: Women glowing in the dark - biomed & sciart project
DESCRIPTION: Creation of a social media that connects women together via the artistic display and the mapping of their menstruations.

e.g. What if we would give the chance to women to make their mentrual blood glowing and encourage them to share the visual result on an interactive platform?

The project aims to:
(1) Fight the taboo that surrounds feminine menstruation and contribute to women empowerment in a fun way
(2) Bring awareness about women health related issues
(3) Help acquiring real-time geo-localized data that may contribute to the advancement of woman health related biomedical research.

An extension of the project to the breast feeding topic is not excluded.

EQUIPMENT/SKILLS/PEOPLE NEEDED:
    PEOPLE:
    
    App designers / IT folk who could provide help prototyping:
    (1) an app that could be kind of an hybrid between instagram and an interactive google map.
    (2) a connection between the app and a platform that would store the anonymously acquired data .  
    
    Biologist / biochemists / chemists who could help designing 'visual' chemical reactions with blood: 
    e.g. Luminol, in order to produce light from the reaction with blood like in the piece Blood lamp designed by Mike Thompson http://thoughtcollider.nl/project/blood-lamp
    But also other reagents - if possible natural? - that could react with e.g. hormones such oestrogenes, prostaglandines etc.
    
    And who ever feels concerned, inspired, enthousiast or even critical about the thematic ;)
    
    EQUIPMENT:
    - Stuff needed for the app
    - Biochemical reagent (e.g. luminol)
    - Blood samples
