The pic controls the DC motor. It's like any other controller, with some basic C or assembly language skills, you can have that pic control when the motor turns on or off. Shouldn't be too hard to control voltage either.

Hmmm, I took a course in C++. I was horrible at it, but maybe I can do this. Where might I find this PIC? Are they expensive?

I think we can use 2 transformers, 12v and 24v, wire them parallel and to the pump. Plug both into Chauvet timer, select 2 channel and fast chase 1 sec. to 1 min, adjust the duration. Chauvet will switch between 24v and 12v and the pump will continuously run at 24v and 12v without stopping at all, great for for wave box. This is easiest way, imo.

A great find, but isn't this the same as the powerstrip type wavemakers? Also will the fast on and off shorten the life of the transformers? I know the pump is on all the time so it should be ok.

Also will it be harmful connnecting two transformers in parrallel, one is live one is not, back and forth?

I know these are rated at aroung 4000gph on the top end. These put out more than 2 Hydor Koralia 4s for sure. I had two 4s on the left and this on the right and it pushed the water column pretty far towards the 4s basically meaning two 4s couldn't beat push it back on the high end. I think 3 might tie it as I added a Tunze 6045 and the flow started to even out in the middle of my tank, but was still being pushed towards the 3 pumps.

I also hacked the controller off and wired the brick directly to the pump. Oddly the transformer kicks zero volts out. It must need a specific load before it will push full voltage out... probably a safety feature. The transformer still will power the controller and the pump when wired back up. On my bench, I reved the pump up to 24v and it was pulling about 1300ma. Unfortunately I don't have a power supply that kicks out 24v at 1500ma that I can use to get this in my tank for long term testing. I plan on ordering one for $10 and see how long the pump will run full out. I did try it out at 12v with a PC power supply in a test tank I have and the pump fired right up but obviously at around half power.

Hope this helps... this pump has great potential and while it is big they did three things very right IMO. First, it is DC which means no worrying about prop running backwards if it is wired properly and it can be slowed down easily. Second, the pump is wide rather than tall. It has a reasonably slim profile as it is wider than tall. Lastly, the pump doesn't have any slots for intake water at the top which allows the pump to be closer to the surface without a vortech and sucking air into the pump. Nice if it were on a magnetic base, but you can pick up some strong acrylic coated magnets for 10-15 bucks.

Where can you get those magnets, I have one I would love to mount differently.

For waveboxes you often need to set the timing to less than one second (depending on the size/shape of tank, position of wavebox). Furthermore, you need to have fine tunning ability for the timing - certainly within a tenth of a second, or better. I believe Melev's Reef has a diy timer that he rigged for a Tunze to make a wavebox. I'm sure it should work for this. It seems a little less hairy than the Chauvet method IMO.

L98-Z · #**158** 07/21/2007, 03:58 PM

Tenths of a second aren't hard with a microcontroller. I'm pretty certain I could figure it out. The problem is I don't want to buy their controller and pump, only to get the pump. It's a waste of money.

aninjaatemyshoe · #**159** 07/21/2007, 04:42 PM

I was wrong about the source. Here is the link to the schematics for the controller used:

aninjaatemyshoe · #**160** 07/21/2007, 04:43 PM

Of course, this design would have to be modified to fit the Resun, but I think it gives the basic idea for those who are good with circuits (which I am not).

It's a basic 555 timer. It's not nearly as accurate as what you can do with a microcontroller, but it's simple enough for anyone to understand.

Brent Thomann · #**163** 07/23/2007, 09:44 AM

for a magnet-

I used a sure grip 100 and slightly modified it to fit my Resun Waver-15000, works great. Super glued one of the mounts to the Resun.

hi could u share it with us ? Photos ? Etc.

markandkristen · #**165** 07/30/2007, 11:21 PM

im looking at getting 4 of these for my 150 what are your thoughts so far on these looks like pretty good on pump average on the wavemaker

markandkristen · #**166** 08/04/2007, 07:03 PM

any more opinions on this wavemaker

eastcoaster1 · #**167** 08/04/2007, 07:18 PM

After I fixed the problem with mine it has been running non-stop for the last 5 months.
I just wish the controller allowed for more adjustment.
I'd really like to run mine full blast for 2-3 minutes, rather than the max of around 10 seconds.

markandkristen · #**168** 08/04/2007, 07:48 PM

eastercoaster1 do you think these pumps really push the 39?? gph

Straegen · #**169** 08/05/2007, 10:21 AM

A $10 24v 1500ma AC/DC transformer off ebay runs this thing full out all the time.

I don't think they push 4000gph or really close to it. They are probably around 3000gph, but that is still some monster flow for the price. Also while large, it isn't any bigger than other pumps that throw out that kind of flow.

eastcoaster1 · #**170** 08/07/2007, 05:17 AM

I find it really hard to judge the flow from the stream style pumps.
The resun pushes more than a maxi-jet 1200 that I modded, but I doubt it's close to 4000 GPH. 2000-3000 is probably more accurate.
The real problem with these pumps is the limitations imposed by the controller. 3000 GPH is a lot of flow, but if the pump only does that much for 8 seconds, then that's not enough time to really get the tank water moving.
I’ve got a 120 and the flow from the pump doesn’t have a chance to get the water moving on the far end of the tank before the controller kicks the pump down to the lowest setting.
As Straegen suggested, I might just do away with the controller all together, but then I’d have a 3000 GPH pump that draws 30 watts. Not really all that efficient.

They aren’t bad pumps, especially for the money, but I think they are better suited for a smaller tank.

I've recently encountered a propeller sticking problem with one of the three I have. I turn then off during feeding and when I plug them back in only one needs a push with a finger to get it started again. Any thoughts? Maybe a cleaning. I haven't had them in for very long I would find it hard to believe they need to be cleaned already.

eastcoaster1 · #**172** 08/07/2007, 07:19 PM

I'd give it a cleaning and see if that helps. Maybe the pump sucked in something and it got wrapped around the impeller.

L98-Z · #**173** 08/07/2007, 08:14 PM

Has anyone found an equivalent pump (DC?) or found a place just to buy the pump yet?

quangtam7 · #**174** 08/08/2007, 03:20 AM

Here is my dc picostream

(the other is maxijet) about the size of small egg. It spins Dumas 1.25" prop easily, the flow is as strong as modded mj 600, I would say at least 600 gph.

did you get it fixed yet.. did it just need cleaning?
