Electronic Skateboarding Assistant
I love skateboarding. When a skater is practicing alone, he cannot observe himself for sure, thus unable to correct himself. Yet if he sees others making moves, he can tell what part others did wrong. So I decide to design a device to solve the problem. A 3-axis accelerometer is enough for my goal. By recording down the acceleration of the skateboard’s move, skaters can have a clear view of what he did and know where to correct. By comparing the data with the pro’s data, we can even acquire more information. It makes practicing more accurate and scientific. The Electronic Skateboarding Assistant is definitely a good news for the novice skaters!

Our project concerns the assembly of customer-assembly furniture. One problem is that disposable tools have to be used, which are often of an inferior quality. This makes it hard and time-consuming for the purchaser to assemble the furniture. If this tool is superfluous, the product will at the same time be cheaper and less environmentally injurious. Our solution is the incremental innovation Boltstrips, which is an innovative bolt and matching nut, functioning according to the same principle as a strip. The actual bolt has a number of grooves and in the nut are some small teeth. When the nut is lead down over the bolt, the teeth simply lock around the bolt and ensure that the nut cannot return. This movement can be effectuated by hand which makes assembly of customer-assembly furniture both more effective and user-friendly. Furthermore, we have developed several models, that enable Boltstrips to be used for different purposes and, most important of all, it can also be disassembled.
How Can We Create a System Able to Solve a Rubik's Cube?
Everybody knows this famous puzzle created in the 1980s by Ernő Rubik, a Hungarian architect and design professor. 30 years after, it still fascinates people and especially these three French students who wanted to know if they were able to create a robot which could solve the Cube alone and which can be as efficient as robots we can see on the Internet. This project is about artificial intelligences and to study that, they build a robot able to solve the famous puzzle alone, without any help after someone gave him a mixed cube and ordered to set the puzzle in its solved state. To do that, the robot must be able to analyze, to calculate and manipulate the cube and that is what they worked on by programming an algorithm based on methods they use when they play with the Cube, by imagining a mechanical system able to do all the moves to manipulate the Cube and by creating a system of analyze and all the necessary to link all the components of the robot.

Antileaks - a Device for Detection and Discontinuation of Leakages in Water Supply Systems
One of the difficult problems in the water economy is that of water losses in supply systems. The proposed approaches to treat this problem available today are inadequate and do not provide a comprehensive solution. The device we have built is designed to detect leakages in these systems and stop them. First, the system analyzes the consumer's average water consumption over a period of time based on a mathematical model. The system keeps measuring and analyzing the water consumption in real time. In case it detected a great deviation from the average or steady water consumption over a period of time it alert the consumer by cellular communication – and if necessary disconnects the leaking system from the water supplier. Additionally, the system can send data about the consumption to a nearby computer in wireless communication.
L.C.T. - Low Cost Titrator
L.C.T. is a device which is able to perform one of the most important chemical analyses in laboratories: titration. Our prototype is able to perform an acid-base titration. Currently commercially available devices of this kind exploit ultra precise burettes driven by worm screws with extremely low pitch in order to combine the solution up to equivalence, with very high precision that is the measuring unit of pL. The nozzles of the latest ink-jet printers dispense ink droplets with a precision similar to pL. Noticing this analogy, we thought we could transform an ordinary ink-jet printer into a titrator able to execute the same functions. A substantial difference of the two automata is the cost: a printer costs about € 50.00, whilst a titrator is about €20,000.00. With our L.C.T. we have demonstrated not only that these printers would no longer be thrown away, but that they could be transformed into a “high precision titrator” and still maintain their ordinary function as printers.
Protective Cases for Mobile Phones
EU citizens are concerned about potential effects of electromagnetic radiation (EMR) from mobile phones on human health. The aim of our study is to design and test protective cases for mobile phones in order to reduce their EMR. We used stainless steel yarns to make 2 types of shielding materials: knitted (only from these yarns) and woven (conductive yarns were inserted as a mesh into woven fabrics). These fabrics were used to design protective cases for mobile phones. It was found that the most successful protective case can reduce EMR by 90% down to a safe level. We have noted that the distribution manner of conductive yarns in the fabric is very important for protective features of the material – a mesh of conductive yarns inserted in woven fabrics is more effective than knitted fabrics made entirely from the same yarns. Our tests show that the use of protective cases does not influence mobile phone connectivity or battery discharge time.
3 Dimensional Display
Nowadays we are witnessing a wave in the development of 3-Dimensional displays. The industry presented us with 3D screens and TVs. However the Stereoscopic technology used in most of these devices proves rather unnatural to our eyes. The aim of this project is to build a 3-Dimensional display that can display ‘real’ 3D images. The entire project is based on the idea that if more than one transparent image is put in front of each other, a 3D image forms. Persistence of vision was used to create the needed layers. A line of LEDs was rotated, synchronizing the LEDs on and off with its speed. This gave the illusion of an image in midair and when more than one layer was placed after it a 3D image formed. This 3-Dimensional display could have infinite possible applications in the future like 3D telephony, 3D games and 3D modelling.

Nowadays the conception of using robots in daily life is getting more and more actual. They can be used in a great number of situations. Among them are: investigators, archeological, or military works or help to disabled persons (invalids). It`s a long and quite difficult process to make a special robots for each type of work, so I decided to make a robot which would be universal. I`ve gathered many electronic devices and connected it all in one universal robot which can help or even replace people in the great number of situations.
Automatic Lock for a School Locker
The main objective of the project is the improvement of the identification systems in schools, but a problem of lockers is specified. The goal has been fulfilled as a new locker has been designed. All the criteria for the new locker has been achieved, the new design of the locker offers instant time spent to unlock the locker, it is extremely easy to use and the human factor is not present anymore. It is an extensive improvement from the versions of locks that are currently used while still retaining the low price. A lock, designed for use in school lockers is assembled using three modules: the access control module, electro-mechanical module and the power supply module. If a lock would become defect for any reason, only the defect module would have to be replaced and the lock would function, which massively reduces the maintaining costs.
Plastic Bottle and Tin Can Separator
Garbage puts a heavy burden on the environment which is a problem we also face at our school. Drink vending machines offer drinks in plastic and tin packaging and are producing large amounts of waste. To solve this problem, we decided to construct a device that would offer a single disposal area and automatic waste sorting system to grind plastic bottles into granules and compress tin cans. We were unable to find relevant literature that would help us with the construction of a waste grinder or press, so we drew plans ourselves. At first glance the waste separator seems to be a simple element, but the possibility of wrong material input and feeding the recyclables too fast, presented a difficult technical challenge. We developed four different solutions to find the most appropriate one. The device is controlled by the programmable logic controller Siemens Simatic S7. All the component parts are bound together in a single housing.
Hopefully, our device will help to a cleaner environment.

pi Cam - The Development of a Camming Device for Climbing
The project pi Cam describes the development of a revolutionary device for climbing. Camming devices are part of the safety gear used in rock and industrial climbing. They help to create an anchoring point where no preattached bolts exist. The current camming devices are secured in a crack or between two parallel surfaces. The newly invented pi Cam however uses rock protrusions like e.g. flakes, limestone traces or tufa to create anchoring points. Thus, the device enlarges the range of protectable rock formations and increases the safety of the climber. In industrial climbing, too, safety is of the highest priority. On pillars for example pi Cam can provide an anchoring point to workers high above the ground. Obviously pi Cam opens new horizons for climbers in many different situations. It is therefore not surprising that specialists have shown interest in the development and commercial production of this new device and that it has already been applied for patent.*pi=greek small letter.

Optical Characterisation & Mechanical Design for Accurate Imaging
CityScan, designed by the University of Leicester, provides an air quality monitoring system that leads to a tomographic retrieval in urban areas. It was crucial that the data could be related to a known location. An accurate image monitoring system and corresponding analysis software was developed that verified the unit’s accuracy and provided a real time perspective to the air quality data. The design and manufacture of a bespoke mount that securely positioned a webcam in the CityScan unit and the analysis of the webcam image to identify and correct the distortion was undertaken to achieve this. The culmination of this work is a panoramic view, that when superimposed on air quality data, will provide high resolution maps of time varying air quality compounds in context with their surroundings. This will allow side by side comparison of pollution data and visual images, resulting in excellent knowledge of the sources that are responsible for influencing the air quality measurements.
