Hi everyone,

I wanted to get some advice for a water gun alarm clock which I want to build for a children's television show.

So far I have an 2xAA powered alarm clock and I have cut the wires going to the speaker.

The water gun which is available is a 9.5V rechargeable Water Warriors Tarantula http://www.buzzbeetoys.com/USglobal/WaterWarriors/01660.html.

What steps do I need to take to make the watergun controllable by the alarm clock?

Do i need a voltage relay switch or should i connect the alarm directly to the water gun?

Many thanks,

Geoff

Have a look at the circuit I would recommend here.

Just remove the LED and LED resistor and replace the bell motor with the gun.
