Design and development of solar cells in electric vehicle prototype intended to Design and development of solar cells in electric vehicle prototype Case study electric cars of Rajamangala University of Technology Phra Nakhon. The research process begins with the solar experiment model Solar Thin Film a bent size 19.2 x 9.5 cm technology has applications in Unmanned Aerial Vehicle install to a source of clean electricity generation using 80 Solar Thin Film Cells controlled by Arduino mega size 101.52x 53.3 mm Programming software by Arduino-1.6.9-Windows and Show the result at LCD Solar Monitor Charger from batteries store the electrical energy size 12V/28AH 6 pack for the results showed that such a circuit can charge electricity 5A to 1 hour and to expand the use of rechargeable battery electric prototype instead of using electric vehicle prototype from charging normally Requires 480 Solar Thin Film Cells in trial period hypothesis 6 hour/day. In term of investment evaluation simple payback period is expected to be 4 years. Considering sensitivity analysis it is found that the most sensitive factor is electricity cost cost Solar Thin Film and the cost of Evlink Fast Charge Solution respectively. The results of this study can be used to support decision making in design and development of electric vehicle prototype in the next generation more efficiently

The project of design and development of textile product using Thai Song Dam’s stitching technique at Supanburi provinces. “Nowadays it was difficult to find someone who loves weaving; however finding someone who loves stitching was more difficult. The designs of stitching pattern were altered by trend; however they still kept in their identity” Mrs. Lamduan Konthong a specialist in Thai Song Dam’s embroidering style said. According to the questionnaire regarding the requirement of the sample it showed that the sample was interested in the textile products for living room decoration such as a backrest pillow a decorating table runner and a lantern. Thai Song Dam’ stitching technique and “Kor Kood” pattern should be applied with the design of the designated products. To find the appropriate fabric for stitching the experiment was done by stitching of “Kor Kood” pattern on the following type of cotton silk linen hemp and knitted fabric. The chosen one was linen fabric because of its light weight good dimensional stability. To create the model of the products and find the appropriate pattern for stitching the pattern was designed by the concept of Art Nuvo characterized by the appearance of woman. From the questionnaire it was found that the satisfaction of the sample regarding the design of the Thai Song Dam’s stitching in textile products were as follows; 66% kept in the identity of Thai Song Dam 72% style the products of Thai Song Dam 58% Thai Song Dam style the design of the products characterized by Art Nuvo 50% suitable the composition of the pattern of the products 74% suitable the whole pattern design of the products 64% suitable the colors of silk stitching on the products 60% suitable the use of colors of the products 60% suitable the size of the products and 62% suitable for the purposes of using.

The project of design and development of textile product using wrap yarn printing with natural dyes by silk screen technique. The purpose of this study was to find out the silk screen printing technique for patterning on Ikat or Mud Mee textile. Due to the complicated Mud Mee process for patterning the design on Mud Mee textile silk screen printing was chosen because of its convenience and rapidity. Silk screen printed on warp yarn with dyed weft yarn created the plain weave pattern. Pattern design was inspired by the natural form of vortex. Such form was applied with silk screen printing technique with extract of natural dye from jackfruit heartwood. The research showed that the product interested the sample was home textile product by using for bedroom which designed using home textile design principle. Three tone of color were chosen for warp yarn by screen printing technique such as red colour from lac blue colour from natural indigo and yellow colour from jackfruit heartwood . Weft yarn were dyed with lac and natural indigo using cationic agent. The cationic agent using before mordanting along with dying by 5 g/l aluminum potassium sulfate (alum) which is the best result because the outcome colors were intense and bright like vermilion and natural indigo. The color extracted from jackfruit heartwood was used for silk screen printing process. Color extracted from jackfruit heartwoodwas in the form of powder color integrated with 4% sodium alginate. The viscosity was optimize for printing. Printed warp yarn was dried at 120 °C. Weaving in plain weave pattern which created the strength structure of textile. Mordants with alum showed bright and intense color. The fastness tests were at good to excellent level for producing home textile product for bedroom application. From the questionnaire it was found that the satisfaction of the sample were as follows 54% printing fabric by printing of warp yarn is similar to Mud Mee weaving 58% textile made by printed warp yarn showed the identity of Thai color tone using for printing 80% weaving pattern design inspired by the form of vortex was suitable 84 % plain textile was suitable for weaving in the form of vortex 64 % the composition of the whole pattern of the products was suitable 86% the color of the pattern was suitable 70% the color of the weft yarn was suitable with the color of the pattern 76 % the size of the products was fitting and 92 % the products were suitable for the purpose of using.

The purpose of this project is to study and develop the products group basketry Detail Ratchaburi province. For evaluation and customer satisfaction in product are Usage patterns bag of woven bamboo. The researchers have collecting relevant information And interview 50 customers who come to shop for basketry detail products in Ratchaburi Province. Researchers verify the integrity of the research. Assessment and monitoring rating According to criteria set and points to a statistical method based on the analysis by the program Finished and presented in a table format to sort for which complete data. Research of this results and concluded that they should see to study and develop the products Group basketry detail in Ratchaburi province. To increase sales of bag products to be more interesting And convey the identity of Ratchaburi province. for generate income for the community in Yanghak Sub-district Pak the district Ratchaburi province. In a new Format that is different from the original format to suit. the needs of the group and identity of Ratchaburi province. product is haversack handbag sling bag and pencil bag.

The project was intended to improve the design of feeding bowl. The researcher was conducted by the original product the shape of use. The researcher studied data analysis and collect the information that related by questionnaire of 50 items to study the behavior’s dog and the owner e related information that relevant information from the observation of everyday and interviews with the others to be the information for study the behavior of owner and dog. The results of this study founded the feeding bowl and cleaning the feeding bowl was designing for the dogs can eat 5-6 dogs. The product can be cleaned by wiping the blades with food scraps into your food waste by using the pedal force the blade rotation.
