      Why FabLab?
      Final Project
       -Problem consciousness
      - Concept
      - Fabrication
    • Why FabLab?
    • 1.Sympathywith vision.
      Just giving product might not work well when it broken or reach life time.
      But sharing information how to make it will work. This is what I learned in Kenya.
    • 2.Lack of skills.
      When I tried to repair solar lanterns which are broken, but I could not do it because of lack of skills.
    • Final Project
    • Problem consciousness
      In a village where there is no electrify in Kenya, people use kerosene lamp.
      But there are disadvantages.
      Emitting toxic smoke
      Risk of fire
      Running cost to buy kerosene
    • Problem consciousness
      Solar lantern could be alternative light by solving issues. But, still there are points to be improved.
      Once it is broken or reach life time, you have to get another one.
      Also, poor can afford to buy it because of high price
    • Concept
      Appropriate light that people in village can make it by using local available materials and tools.
    • Fabrication- Dynamo lantern-
      Generation
      Lantern
      Battery
      Solar lantern
      Dynamo lantern
    • Fabrication- Dynamo lantern-
      Generation
      Lantern
      Battery
      Solar lantern
      Parts of generation, PV panel, and battery, H-Ni battery(Ni-CD battery), are expensive and it is not easy to get it at even in town. We need to think alternative way to meet the concept.
    • Fabrication- Dynamo lantern-
      Generation
      Lantern
      Battery
      Dynamo lantern
      To meet the concept, I would like to start to think to use dynamo as a generation and lead acid batteryas a battery
    • Generation
      There are so many people who do business with bicycle.
    • Generation
      It is effective to charge battery during the period of working
    • Battery
      There are so many motorbike in a village, so that lead battery is available there.
    • Battery
      There are batteries(worn-out battery) that can not work for motorbike but work for LED Lamp
    • Battery
      A box in which a battery is put inside is set in front of bicycle.
    • h
      Battery
    • Lantern
      I designed the lantern whose concept is to use less material as much as possible but emit bright light.
    • Lantern
    • Lantern
      I used the principleof light guide plate. The surface of acrylic glasswas scratched.
    • Lantern
      Number of LEDs I can use is three because of voltage of lead battery
