Here is a fun project that didn't take a whole lot of time or money. You take a boogie board and add a submersible bildge pump or water pump with batteries and make a fun pool water craft. Check out the video.
Step 1: Parts and Tools
Bildge Pump I used 1200 GPH MUST BE A SUBMERSIBLE PUMP
Waterproof Switch (Momentary on, or Switch on)
Batteries (2 6v 5 amp wired in series with switch)
PVC pipe and a couple fittings 1/2 inch sch40. refer to pic for type.
Large Plastic Ties
Dremmel, Soldering kit, wire cutters, BRAINS
Take the Pump and Quick steel one end of the steering control piece to the pump.
Cut the 1/2 inch pvc pipe to the debth of the board. You want it a tiny bit longer so it will spin once you tighten the control steering pieces together.
Take the 1/2 inch Coupler to female threaded pipe fitting and Quick steel the other steering control piece to the coupler side.
It should look like this when completed.
You can now install onto Boogie board. You may want to drill a small hole for the wires to run from the pump up through the board to the top of the board for wiring. I ran mine on the outside part of the hole. I'm not worried because the board is styrofoam. It will not wear the coating off the wires.
Here is what it will look like on the bottom and top view.
Attaching the batteries to board with large zip ties. I zipped them pretty tight to hold them firmly.
I added some extra PVC pipe for board support. You may not need this. I used the same type of large zip ties.
This is the wiring stage of the project. Please look at the picture with yellow description boxes for visual understanding.
I added this as an extra step to explain that you need a marine grade silicon sealant to cover and protect all electrical connections. MAKE SURE YOU COVER ALL EXPOSED ELECTRICAL CONNECTIONS PERFECTLY. DO NOT SKIMP ON SILICON.
