Fab Academy 2015, Dong-Hyun Kim
Applications and Implications
What will it to ?
Open Bicycle
Open Bicycle is Programmable DIY bicycle. It has Fabduino and all the instructions are open, so everybody can make their own bicycle. Every users who made ‘Open Bicycle’ can customize With Fabduino.
And also in my final idea I will make internet sharing platform like ‘Thingiverse’, Participants can share their own DIY parts like actuators, sensors and add on modules.
Who’s done what beforehand
Evo Utility Bicycle (www.evoutilitybike.com)
It is a Modular Bicycle, It has a same structure for add on modules in front of the bicycle and rear either.
Especially, they made using metal 3D Printer for making complex structures. So they could make very efficiency structure for add on modules.
ROOTLESS (www.rootless.tk)
Rootless is made with wood, in case of main frame, is fabricated with digital fabrication machine(CNC Router), CAD Modeling files(for making bicycle body) and instructions are opened on the internet, So, everybody can make their own bicycle easily.
Helios (www.ridehelios.com)
Helios Handle bar has Bluetooth and GPS Sensor, if you change your handle bar to Helios, You can add brain into your bicycle. Using Bluetooth wireless technology, can acces your smart phone and control head light and rear LED easily. And Using GPS Sensor , users can recognize their bicycle’s location and speed.
What materials and components will be required ?
Wood
Copper board
Epoxy
Acryl
Electric components(SMD LED, Line LED)
Where will they come from ?
Almost around our fab lab (it’s a similar with Shenzen.
How much will it cost ?
Wood : 50$
Copper board : 10$
Epoxy : 10$
Acryl : 15$
Electric components(SMD LED, Line LED) : 30$
Total Cost : 115$
What parts and systems will be made ?
Hardwares
Bicycle mainframe (Laser Cutting, Composites)
Rear wheel holding bracket(CNC Machining)
Electronics
Auto ringing(3-axis accelerometer, Speaker)
Rear LED(LED array)
What processes will be used ?
-
- Computer-controlled cutting
For making main body, laser cut wood sheet layer by layer.
-
- Electronics production
Redesign fabduino and Control LED array, LED strip, that will be installed in main body of bicycle.
-
- Computer-controlled machining
Main body
-
- Molding and casting
Fabricate timing belt gear
-
- Input devices
Make 3-axis accelerometer, Button switch
-
- Output devices
LED array, LED Strip, Speaker
-
- Composites
Composite acryl, wood and fiber glass for making main body
-
- Networking and communication
Among network between fabduino and sensors, pass the data and do processing
What tasks need to be completed ?
Composites : For making left and right frame, Do composition with acryl and wood sheet. For plant LED strip into frame body, cut a center of acryl and wood sheet.
CNC : for plant front fork and Seat post, mill an wood with CNC Router
Electronics : Redesign Fabduino for reducing useless pin, and network with various sensors(GPS, LED Strip, LED array..)
What questions need to be answered ?
How could I control LED strip when I grab brake(bend a flex sensor)?
How to plant LED strip between wooden sheets?
How to bend a wood?
What is the schedule ?
How will it be evaluated ?
Has the bicycle been designed with correct parameter?
Has LED array and LED Strip been controlled correctly?
Is it customizable?
