Re: Ferrara Tanker
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.
[IMG][/IMG] 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. [IMG][/IMG] The inside tank bottom is sloped to promote drainage. [IMG][/IMG] The tank just sits on the frame rails. I’ll probably strap it down with velcro so it’s easily removed. [IMG][/IMG] 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. [IMG][/IMG] Here’s a video of the chute. I’ll see if I can make the chute open the compartment door to be added later. https://nam11.safelinks.protection.o...amp;reserved=0 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. https://nam11.safelinks.protection.o...amp;reserved=0 |

Re: Ferrara Tanker
I pressed some brass electrodes thru the side of the tank and created a water level sensor using some transistors, resistors and LEDs.
[IMG][/IMG] Also added a fill tower to the tank. [IMG][/IMG] Siren speaker mounted between the front frame rails. [IMG][/IMG] Printed the front bumper skin and added hose troughs, tow hooks, fake horn, and gated wye. [IMG][/IMG] |

Re: Ferrara Tanker
Testing the deck gun and dump chute with the tank installed.
