DIY ballistic chronograph / FPS Reader

This is a printable case for an Arduino Uno based ballistic chronograph / fps reader meant for Dartblasters like Nerf.

Its based on the really great arduino code from paperskeletons3d. He is the great mastermind behind this DIY Chrono! I just made a fancy housing :-)

Files include:

• main housing
• cover
• small distance rings (eventually needed for the sensors to screw on)
• small frame (meant to hold the display in place)

you will need following hardware:

- 1x Arduino UNO (or Clone)
- 1x I2C Display 0,91 (128 x 32)
- 2x TCRT 5000 Sensors
- 4x Heat Inserts M3 (for cover screws)
- 4x M3x10mm InnerHex Screw (cover screws)
- 7x standard Nerf Screws (for arduino, sensor and display)

it can all be printed in PLA without any supports.

Pictures show a first prototype (additional off switch hasn't made it to the final version).

Let me know if you have any issues
