Making a low-cost Braille printer using the existing open source braille project. We are making this project to make it cheaper and more accessible to visually disabled people.This project is inspired by an open source project named OpenBraille which is made by Carlos Campos.(http://www.instructables.com/id/OpenBraille-a-DIY-Braille-Embosser/)

All the components are listed in the above link.
We made modifications in the wheel that is attached to the pin head encoder. The 3d printed wheel had some gap between them due to which there were levelling issues. Due to this problem the wheel had stability issues and was toppling.
We attached some padding (Double Sided Tape)
on both the surfaces of the wheel in order to give it some stability.
We fabricated the pin head encoder of the braille printer. The part was 3-d printed and also the nails were made according to the design provided in the Instructable project guideline
We laser printed the body of Open braille using a 10mm wooden plywood. We made the design on Autodesk Fusion 360 using the dimension provided in the Instructable project.
OpenBraille uses widely available parts on the market. Most of the components are originally used for 3D printers. The brain of the embosser is an arduino mega with a RAMPS board. The following parts are needed for the build:
Arduino Mega 2560
RAMPS board
Stepper Drivers
End Stops
Servo Motor
Steppers
Rods
Lead Screw Rods
Power supply
Coupler
Bearing
Screws
Printer carriage
10mm wood
