just use pumps?
It seems the most difficult part of these designs (whether DIY or manufactured) is creating a single device that can both suck and purge reliably...why not just hook a pair of closed-loop little giant pumps to a dual wavemaker power center, set the returns at opposing ends of the tank, and dial the timing in so they turn on and off exactly as the surge reaches the other side of the tank (longer tank = longer time between surges)?
If you prefer a wider surge, then just spread the flow over several horizontal outlets...or even across a square matrix of returns (like a checkerboard). With this system you can adjust exactly the placement and power of the surge...no belts, boxes, obtrusive sounds, or headaches. |

I've been looking at this and the swirler stein thread and had an idea.
What about making the front of the wavebox round, match the mjmod housing to the curvature and put the mj on a swirler with a 90degree path(or more), cut a hole out at the halfway mark and bam, you've got open/close time. Change the timing by the speed of the swirler. Or you could cut a hole at 0 degrees and 90 degrees, might produce some interesting flow charateristics. You would have to figure out the curvature of the front panel based on the arc of the swirler so that it would tightly hold up to it, as well as possably a ball and socket to the back of the base so that it wouldn't push away while being in the "closed" position. Make sense? |

Do RC motors for Boats have potential ( the Brushless ones ) the current is doable the only thing I'm worried about is the life.
I plan on direct driving a propeller with a long shaft and the motor mounted above the box and out of the water. It wont even have to run reverse but it would feel slight back pressure. Thoughts Dan

The brushless motor would be fine with the cycles. They have no wear parts.
Last I was into RC those motors and controllers were expensive. It might be more cost effective to go with the tunze 6055 or similar. BTW I did some diy'ing and came up with something of interest but havent perfected it so I'm not telling just yet. Here is a teaser. It is not a modded maxijet or tunze and cost less than $50! =P http://www.youtube.com/watch?v=g9JiFR-H3Sw

Would a regular style powerhead work, or does it need to be that style where its open and more of a fan design than a turbo design? I'd think any style would work as long as the water can reverse flow fast enough in it, but I have no experience with wave boxes. I'm thinking Ill make an external one mounted behind the aquarium with the inlet/outlet leading around to the side of the tank for proper wave formation.
One other question I had was what do you use to time the pump so its only on for a second and then off for a second in a continuous cycle? Would the float switch idea be better than the timed method? |

Someone with some crazy DIY skills could design a motor that turns that drives a piston up and down with a pipe connected to the aquarium sucking water in and pushing it out the cylinder would have to be water tight yet have to moved up and down.

How do you think this would work out? I would imagine the plumbing would have to be pretty large to allow the siphon to refill the wavebox fast enough. I'd think around 1.5" or 2", but it would keep the wavebox out of the tank as well as allow it to be out of the tank without drilling for those who already have established tanks that don't want it mounted inside the display. Thoughts?

i used the chauvet timer but the ecomod i was using only lasted like 24 hours. the blades broke off the shaft of the propeller and the rubber on the end of the shafts melted away from the start stop, which caused there to be no stop. after they melted, sometimes the pump would start in reverse and not be stopped, which would cause the box to fill with water and overflow the top.
on a good note, the timer was perfect for it. no mods at all. just had to dial in the freq. but the ecomod couldn't handle it. the thing was amazing for abotu 24 hours...but then nothing. I was planning on trying other pumps and everything, but i'm a college student and don't have the funds to be buying and testing pumps. if someone else has a pump that could handle it please let me know! keith |
