I started working on the water tank. It’s made from 1/8” ABS sheet and will have a dump valve and motorized chute that extends out of a back compartment for filling the portable pool.

Space around and under the tank is limited and I couldn’t find a ready-made valve that would discharge the tank quickly, so I’m making one out of delrin. It will sit inside the tank and be activated by a solenoid on top of the tank that lifts the plunger.

The inside tank bottom is sloped to promote drainage.

The tank just sits on the frame rails. I’ll probably strap it down with velcro so it’s easily removed.

Here’s the screw drive for the chute mechanism mounted to the underside of the tank. I’m still waiting on resistors so I can remove the potentiometer from the servo. I also need to hook up another switch to activate the dump valve solenoid when the chute is fully extended.

Here’s a video of the chute. I’ll see if I can make the chute open the compartment door to be added later.

I’ve also been learning Arduino so I can program the flash patterns for wig-wag headlights, an arrow bar for the back of the truck and all the warning lights. If I get ambitious, I’ll try to figure out how to change the arrow bar remotely, but for now I’ll just leave it with the center pattern. Here’s a video.
