Hexatile

on
Overview:
Hexatile is a device which can be used at multiple places where illumination is needed. This is a portable device (can be mounted anywhere) , rechargeable and looks cool in the dark.


Requirments:
  • Lipo battery (1200 mah) 
  • TP4056 (lipo charger)Step up module (boost converter or buck converter)
  • Led strips or normal 3mm LED’s
  • Access to a 3d printer (Local maker space)
Process:

3D Printing
  • 3D-print the attached stl files. PLA works best for this project.
  • For the top cover I suggest you to use transparent filament or Translucent white filament to diffuse light.
  • If you don’t have access to that just use a diffusing acrylic sheet.
  • Print those angled part if needed those are to align the led strips at a 45’ degree angle. (optional)
  • Link for STL files: https://www.thingiverse.com/thing:4242966
  
Electronics
  • Connect all your led strip in series. Series connection works best as it doesn’t require higher current value.
  • Solder the ends + and – of the series led to the output of the Boost converter module.
  • Battery terminals are connected to the B+ and B- of TP4056 module. The output of the charging module is connected as input to the Boost converter module.
  • Make sure that the output of the Boost converter module doesn’t exceed 9v else it could burn your LED’s .
  • Finally place the 3d printed cover and use loctite along with m3 screws . Its done!
