"New Idea for wavemaker"

[blueheaven]

Was looking at my Tunze 6060 and wondered if anyone thought of making a wavemaker like a fan?

Basically the propeller blades are like the blades of the fan only that there is this outer rotating part that directs the wind to all directions due to the angle of the flaps.

With this design, we can make a Tunze like wavemaker that distributes the flow

sounds feasible..

ambiguous thread title. Kindly check posting rules and regulations.

contact me via pm for a more appropriate title

BTW..what kind of motorised device to make the part rotate??

will it get stuck like the eden when algae build up in it

[tineng]

read a article once from dunno where that some reefers are using rotor blade and motor from those hobby shop selling remote toy boats..... it is suppose to be cheaper and more effecient wave generator then the converional pump.....

I think it might work as those motorized toy boat is designed to stay in water anyway....the only concern is that the motors might not be designed to run 24x7.....

[Marineman]

It's not the same, it can only make the wind swing from left to right to left and so on. You cannot vary the speed or the force, make it pulse etc.

It will just be like the Eden 228 pump swing from left to right and so on.

[blueheaven]

It'll be like the eden only that it not only swings left and right but up and down too

[giantbicycle]

up to down..maybe possible..but not 360 degree.. as you notice the eden uses gear to rotate the left-and right so maye, you can have a up to down gear too...

[kareen]

I think the idea is great but.... where to find the parts to diy yourself unless u have means of getting the unique parts eg. the rotating parts as seen on the fan?

[typrobin]

to do this, someone with good engineering background is required...and i dun think it will be cheap to frabicate...

[blueheaven]

According to my dad, he says that this works on some gear attached to the blades and the gear ratio causes it to spin slower than the blades

Anyone can clarify?

yup..that's y u need to frabicate the gears...

Would such a big thing in the tank look nice or be practical space wise???

[blueheaven]

Of course not as big as the fan

I was thinking it to be about the size of a Tunze

[Domino]

Oups!! I realize the pic is to illustrate the principle only... Sorry

if the two rotation speed are different (no common multiples) and in opposition, it sould create an interesting periodic "random" movement with a long period.

But the thing would need to be quite small and ideally turn verticaly too...

[blueheaven]

Verticle currents can easily be achieved by varying the angles of the turning part

[terryansimon]

how about the issue of finding a motor or something that allows it to run 24/7 under saltwater conditions?

[pegasus1010]

for the blade how abt those used in portable fan, something like attached pic but with hard plastic for the blades. These can find in toys shops for kids.

Well then the case here is how to make it waterproof rather than having the whole motor running in water

A little unsafe for me

[huiwen]

The rotating blade of the box fan is run by a small slow speed motor mounted at the side of the fan.

I have used these slow speed motor for some of my DIY before

any bro knows where to get the remote control motor boat Propeller ???

last time remember at sim lim tower there is one hobby store selling control plane and boat but not it close already

so any body have any idea where to get the Propeller

Hi all,

Below is a successful diy wavemaker!!!!!!!

[blueheaven]

This is more like a Seaswirl

Looking at the Tunze-type

Fook Hai Building should have. My friend who is into boat rc always gets his stuff from the there.

Cool!!!

Any DIYers gona try their hands on???
