Easy Halloween hack

Because this weekend is Halloween…. here I present you a very easy hack to scare the hell out of the kids coming to your door (or to entertain your kids before Halloween).

Materials:

  • Old rear bike light.
  • AA battery
  • Wasted toilet roll.

Dismount the light, or keep it as it is. In my case, dismount it or it will not fit inside the toilet roll.

Fix the battery to the light (amazingly, this light is able to convert the voltage from this battery and power up 3 LEDS, and I tested and it performs quite well over 5V… interesting).

Draw a scary face in the toilet roll.
