# Overview

Untrickable laser alarm, with an easy-to-knock-out fusebox.

A tribute to (the alarms in) Mark of the Ninja.

# Background

In the game you have to sneak into buildings with high tech alarms. Some of the laser traps can be deactivated by knocking out the fuse box with a dart.

So I made a laser alarm with a fusebox that can be knocked out. This is mainly to keep kids occupied, and motivated to practice throwing.

# Features

• Glowing ⚡ with simple animations and color changes (start-up, alarm, sparks)
• Laser triggered alarm, which can’t be fooled by using a separate laser or flash light. This is done by pulsing the laser and making sure photo resistor is relatively dark when laser is off.
• Motion activated “play dead” (throw somehting on the fuse box, and it will black out for 10 seconds).
• Play sounds for alarm, sparks, start-up

# Demo

Knocking out the alarm (~3MB).

Attempting to fool the alarm (~2MB).
