This project presents an electric bicycle equipped with Solar Cell which will charge the battery with a solar panel. To be used to drive electric bicycles electric bicycles can be powered by two systems that are powered by the users cycling and from brushed DC motors from battery charging with solar panels the test will be tested by charging the panel with a time interval that the output voltage value From the solar panel which time interval is closer to the actual panel at 24 volts and charged into the batteryto test whether the electric bike can actually be used by a test drive starting with a displacement speed of 10 and 20 km/h at a distance of 100 meters. Using experiments with weight sizes of 50 60 and 70 kg respectively it was found that electric bicycles can actually be used. However the above project has been made into two parts. is the part that charges the battery from the solar panel and the second part is a separate electric bicycle.

This research aims to reduce waste in the production process to meet the target to find ways to prevent defects occurring in the curing process and to improve preventative measures available today. The waste found in the curing process label the edges are blamed blistering edge under inflated tires cover on low. After brainstorming to find factors that affect the defect by using techniques Six Sigma (Six Sigma).The work five main steps in performing a job defining the problem measuring analyzing problems improved control and severity surveillance and monitoring disorders of the process. It was found that the raw materials are the main parameters that cause much waste as possible. Therefore we have developed an approach to improve the material by adding a preliminary inspection and design documents to determine work procedures. The benefits of this research can reduce the waste that occurs in the curing process of the target by reducing the rate of 8.0 % an average of 7.3% in a survey from January to May 2557 is an average rate of 6.0% In a survey in June 2557 equivalent to saving manufacturing cost 135045 baht per month. The rate of decline is likely to be quite good that make employees feeling and effort to cooperate in the reduction of waste in the production process.

Private design project for tourists around the Rattanakosin Island researchers have been studying the various documents and research. It led to the design process. Researchers have taken the concept in the design with emphasis on the beauty. To promote tourism. Energy savings. And consistent with the environment around Rattanakosin Island. As well as the comfort of the driver or the traffic on my sidewalk. The development of the bike park to park in the inclination to narrow the width of the base. Beam for more. Handle the bike is in the 140-150 cm in the eyes of the park. I do not have a roof level (that is 2 meters) at the car park at the wheel along with the pressure curve. Hands are placed in 140 cm and the car just to hang on the beam with a height of 170 cm but the car is not perpendicular to the ground because the balance of the car at hand. The car is tilted about 60 degrees the width of 160 cm from the principles already mentioned. We made sure the bike is a beauty and a functional purpose. Analyzing data from the query as follows. - Status (those who use bicycles in the city and tourism) are male than female 68 percent are between 21-30 years of age are 43 percent in undergraduate education is 61 percent. 5000-10000 baht in revenue and a 38 percent majority of the employees 31percent.

This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

This research is Study and design The Tourist Service Center and Rest the bikes and bike lane to develop Thai –Yuan culture tourist . Case study of culture Street. Ampor Sawhai. Province Saraburi. Study of the potential of case area to enhancing the area for tourism development of the area to increase even more. And design a tourist service center building. Rest the bikes path and Lane Bikes Breakpoint. To accommodate and service the ecotourism and Tai-Yuan culture in the area Study and design The tourist service center and rest the bikes and bike lane to develop Thai–Yuan culture tourist. Case study of culture street. Ampor Sawhai. Province Saraburi. Field data collection from down to the area. Using tools such as interview questionnaires in the interview area.Conclusion Building design Tourist center Bicycle break The researcher drew the pattern. The uniqueness of the Tai-Yuan architecture. Applied in the design. To be suitable and the shape of the modern era. Structures and materials are easy to construct and consisten t with the use of functional areas of buildings. access the building and the activity area. By landscaping that creates a shade with space. In the field of product design furniture field tested furniture before production. To test the strength which is at the level that passed the test criteria. The map design. Design has pulled the pattern. The uniqueness of the elements of Tai-Yuan is applied in the design in accordance with the building. In the design of bike lane layout. By designing the bike trails along the Tai-Yuan cultural lane line there are major breakpoints such as the intersection the floating market and the old community in the area. Presentation by analysis with aerial maps and identifying key points. For a design that covers the entire reachable area. The bike lanes offer a conceptual design that emphasizes safety and comfort and creates a good atmosphere for cycling.
