A project log for Kinesthetic Laser Rifle Prop

A laser rifle capable of inflicting little to no damage, but with immersive kinesthetic, auditory, and visual cues that bring realism

To make this 'gun' feel like a GUN, I will require some electronics and other hardwares.

First, a list! I love lists. Especially numbered lists. They make me feel like I am accomplishing something even though I am not...

Components by 'function'::

1. the generator

2. the accelerator

3. the barrel

1. The generator is where it all begins. Here I am going to initiate the sequence - on trigger pull, a bright led in the centroid of the mechanism (the domey part) begins to build in intensity. A sound accompanies the build up; kind of a whirring whine produced by a small BLDC. I will unbalance it slightly to provide some vibration as well.

2. The accelerator is the round glowy bit that is around the domey bit. When the generator has reached peak power, LEDs chase through the accelerator to simulate travel of energy to...

3. The barrel. Before the energy heads down the barrel at ever increasing velocity, there will be a sizable solonoid to give you a bit of a kick. I know that laser guns don't usually have recoil, but mine is better. I will also give the BLDC a sharp spike of juice shaped to get a 'fzzzinnng!' noise as the lights zip down the barrel.

So the trick is to stage and control these main systems:

- generator LED(s)

- generator BLDC

- accelerator LED string

- barrel solenoid

- barrel LED string

My weapons of choice will be:

- the Arduino Nano

- a small LED control board that can control the three groups of LEDs

- a small BLDC and matching ESC

- a 3S LiPo battery (roughly 12V) with at least one UBEC (5-6V)

- and of course the LEDs

- and a laser of course
