How to Make a Water Gun Alarm Clock

Heavy sleepers who continually find themselves late due to a missed alarm clock are in need of something more effective. The sound of the alarm is not enough, so an assault on a different sense is in order. A standard battery-operated alarm clock and a motorized water gun create a wake-up call that the snooze button cannot easily foil.

Difficulty: Moderate

Instructions

Things You'll Need:

• Battery-operated alarm clock
• Motorized water gun
• 16-gauge wire
• Wire stripper
• Voltage relay switch
• Breadboard circuit
• Soldering equipment

1. Open the alarm clock. Snip the two wires that lead from the circuit board to the speaker, leaving as much extra wire as possible.

2. Strip the ends of the two wires leading from the board. Splice and solder two longer pieces of the 16-gauge wire to the ends.

3. Disassemble the water gun. Snip the two wires that lead to the trigger, leaving as much extra wire as possible.

4. Strip the ends to the two wires attached to the trigger. Splice and solder two longer pieces of the 16-gauge wire to the ends.

5. Pop the voltage relay switch into the breadboard circuit. Connect each pair of wires to opposite ends of the switch.

6. Set the alarm and position the water gun to point at the sleeper's face.

Tips & Warnings

• Substitute a regular circuit board if you don't have access to a breadboard circuit. It's a more difficult operation but results in a more permanent connection.
