Nerf Flash Muzzle

Assembled muzzle on the Styfe.

To open the muzzle I had to cut it.

I added the simple reflector to make the flash brighter.

This are the holes for the IR LEDs.

Breadboard.

How it works:

IR LED2 works as emitter and IR LED3 as sensor/receiver. If nothing blocks the line between them - yellow LED3 is on (indicates that the device is on). If the line is blocked by the dart, the flash light LEDs 5 are lighting.

Actually I used 6v battery box, but 9v battery is fine to.

Flash LEDs.

Logic block.

I glued the IR LEDs to the both sides with the hot glue.
