DIY Wavebox! (With modded MJ)

I like the idea of "dimming" the mj has anyone tried this? I think that if this would be possible we could make a timer (somehow) that instead of turning the pump on and off it just goes from 100% power to 20% (made up %) therefor keeping the mj in motion not hearing the stopper click... does this make sense to anyone? Basically just turning off and on the %80 power, always leaving %20 (or whatever is enough to keep it moving) I know basically nothing about electric circuit boards but this doesn't seem too far fetched to make... of course u would want to incorporate a dial to adjust timing of the on and off.... does this seem possible or too complicated?

yes. it will not work with a standard light dimmer. maybe a fan speed switch. would have to size it to the mj.

the mj uses a cframe motor. the way the mj utilizes this type of motor, makes speed difficult to control.

i just weazeled a similar type motor pump that was not epoxy sealed. i am currently trying different things with it.
 
the only way to dim AC current for a motor is to change the frequency. And the only way to do that effectiviliy is change the AC current to DC, change the feq, then back to AC. This is going to be quite an undertaking. Consider if it was efficient technology then why dont the big wavetimer manufacturers get ahold of it? Like the RedSea's or the NaturalSea, I promise if this was pratical, then it would be readily available

I asked this same question.. a few posts before yours :D
I'm glad someone finally answered it.

See above.
 
Here’s a link to my idea on a wave or current device I am going to attach a seio to the end. It is a disco ball motor. I have had it running for 12 days with a 10 pound weight on it. The motor hasn’t stopped or ever got warm. Just thought I would toss it out this thread
Could be a plunger device or anything. Bought of eBay new for $13. with ship

Almost everything I have owned by chovet breaks in 6 - 12 months. Not so bad when its a flashing light thingamabob but if it floods your house...... thats a diff story.

Can it go any faster? It seems really, really slow.

Peace,

These are easy to move. As we've already seen. Floatswitches work. If you are really worried about the security, use the mag-mounted floatswitches initially, then mark where you will permanently mount them in the future.

Peace,

It's a little more involved than that - start with the simple fact that you'll be moving in <1/8" increments... Initial dial-in may take a lot longer than you anticipate. Especially as the timing is relatively sensitive.

If you magmount them - dunno about your magnets but that kind of precision isn't easy to get. Wave action/vibration is likely also to move the magnets. (and we wont discuss kids/pets/significant others).

There's also the re-adjustments that may be required... If water levels changed, pump efficiency changed, resevoir capacity changes (think sediment). The list of variables is long unfortunately.

If you wanted to do it based on float switches you'd be better off using float switches mounted in the main display and some relatively simple relay wiring such that when the wave crests on the far side of the tank, shuts off powerhead, when it hits the near side - turns on. Still you'd need to tinker with timing - but it'd be more reliable than the water level inside the wavebox... But then again you'd need some kind of timer system to help you get going initially.

I was wondering if anyone had a link to the impeller mod for the mj? This is the first I have seen this and went back several pages and didnt see anything on it.
Thanks

Thanks for the link. I really like the swaying action that his wavebox is making in the tank. I have a scwd that I have modded to install on my 180 that I am putting together and was wondering if I would even need this extra circulation with a wavebox running? I wouldnt think that the scwd would switch back and forth fast enough to get the swaying movement that this box is getting. Would this scwd and wavebox just end up fighting each other?

SMCNALLY let us know when you get the taam timer up and running and how it is working out.
Thanks
Jeff
