well, maybe not greatness... but my grandsons love it.
Not bored with the truck, just bored at work one day. Also felt I hadn't been spending enough money on Amazon lately , so I added this to my LMT digger. Over engineered it is not, everything is zip tied in. Total time spent on assembly was about 4 Hrs.
The nozzles were 3D printed, they sorta match the body tie downs so they don't look out of place.
A view of the back of the nozzle and plumbing job.
Water is stored in a bladder. One that a hiker or backpacker would use. It easily holds 12oz. It gets folded and jammed into the cabin of the truck.
The heart of the project is this cheap ($14) diaphragm pump from Amazon. Its rated for 12V and will shoot water 15 or 20 feet at that voltage. Unfortunately at the moment I'm limited to the BEC voltage of 8V as I'm simply using one of those $5 amazon receiver switches (most people use them for LEDs) to control the pump remotely. Next step is to increase the pump voltage to increase the range, though that means I will give up duration.... right now 12oz takes nearly 2 min to fully empty. I need to mount a go-pro on it to collect reactions.... my favorites so far are those that see the water dripping out of the nozzles (the bladder sometimes gets squished) and bend down to get a closer look.....
