In this study, an ongoing Project named FPGA Based Digital Electronics Education (FPGA_b_DEEP) is introduced and the advantages of FPGA(Field Programmable Gate Arrays) technology which brought to digital design area are dealt with by using a case study. The Project aims to develop instructive and attractive examples to teach Digital Electronics efficiently and faster. In addition to this, PBL(Project Based Learning) method and Micro Learning method are dealt with at the study saperately. PBL method has been used partially at the Project and the studies on Micro Learning for association with the Project are going on recently.
The importance of the solar energy usage as a clean source of energy in Turkey is discussed, and combined small capital usage along with State support is analyzed within various scenarios in order to make the sector attractive for investors in every level. Recently, formulated legislations have set up the stage for the solar energy stations in Turkey. Although the price per kWh for which the State guarantees to buy the electricity for is at an acceptable level for small capital owners, high initial investment requirement constitutes a disadvantage because investments at the level of mega watts require millions of dollars. Solar energy investments are not necessarily attractive for local and foreign investors with large capitals. The main reason is the return of investment period being between 8 and 14 yrs. Life of the overall system depending on the structure of the solar panels being 20-24 yrs and even an average of 10 yrs for inverter is an another drawback. The resulting picture shows that the utilization of solar energy in Turkey might end up being less than expected. Various scenarios are produced and analysis is conducted to solve the aforementioned problems. At the first level of the produced solution, turning the small capitals with lower profit mindsets into larger capitals; at the second level, scenarios of State supports and their analysis for investors at any level; and at the third level, the effect of doubling the life of the established system by renewing itself on the scenarios is studied. While developing the scenarios, the profit rate determined for the investors is kept constant while changing the remaining parameters. The issues of how the State supports obtained for the solution be repaid in the long run and other gains for the State are also discussed. In order for the results of the research to be usable, the technical infrastructure of a 10 MW solar energy system and cost analysis are added into this research. The costs of the solar parks selected worldwide are considered in the cost analysis in generalizing the findings. Although the research discusses the setting up solar energy systems and management in Turkey, it is known that similar problems exist in many other places worldwide. V C 2013 AIP Publishing LLC.

Self-generation of energy by residential houses has been met with many obstacles. When PV Solar energy technology is considered, the barriers manifest in problems related to the location, slope, strength, and shade exposure of house roofs are the most common. Therefore, it is not possible to meet daily energy needs from PV panels placed on the existing roofs of many houses. Solar Tracking Systems keep PV panels perpendicular to the Sun throughout the day, providing a significant increase in their efficiency. But the application of these systems on the roofs or houses is not suitable for many reasons, especially in terms of aesthetic appearance. This article is aimed at effectively showing how the slope and direction inconsistencies in the existing roofs of houses in residential areas cause great losses in the performance of PVs; also a research and design study is presented to find a solution to the application of Sun tracking systems in residential areas without creating aesthetic appearance problem. As a solution, combining a dual axis Sun tracking system with an aesthetic looking Gazebo has been considered. A design study was carried out for the targeted system, and the dimensions of a movable platform/roof such a system should have in order to meet the electricity needs of a house from the Sun throughout the year was investigated. How much energy the PV panels can collect annually is determined by a simulation program called “PV performance tool”.
