    D.I.Y. Powerhead controller (wavemaker)

    Well, I had a natural sea powerhead controller go bad on me. I guess thats what happens when it takes a bath in salt water while plugged in. Anyway, one night at work one of the line techs decided he needed to change out a lube spray timer. I told him it didn't need it. Of course he didn't want to listen to me ( yeah ok I have only been doing my job now for 12 years ) So, while he was gone I cleaned the mounting block up and he got back with the new timer and plugged it in.

    He threw the old one in the trash can. Well, I knew it was good so I snatched it.

    I brought it home and cleaned it up and did some research. I found a mode that would work. Then I built this.

    This powerhead controller is programmable from .1 sec ( pointless ) to 9999 hours (way to long). I wired the switch output to a duplex outlet with the bridges disconnected. Works like a champ. Now I can program my modded powerheads to switch every 6 minutes.

    The natural sea would only do 3 minutes.

    Here are some pics.

    Front of the timer


    As you can see it has analog buttons to set the time and a digital display to show how long in the countdown cycle is left. The timer is an Omron H3CA



    I used regular blue plastic outlet boxes to mount everything in.



    I took 2 of the boxes and epoxied them together side to side slightly staggered. Then drilled a hole in the wall ajoining the 2. this way I could pass wires from the timer to the plug in.



    It works very well. I told the line techs if they need to change anymore please save them for me. SO they will be saving them to test to see if any are good.

    Hope you like it.

    Thank you.

    The nice thing with this is each side of the switch will handle 3A. I read somewhere, where a MJ1600 modded is pulling like 9-10W thats it. So you can actually control like 30 powerheads with this unit. Way more than anyone would use. LOL. But at least I know that I can always expand it it needed.

    Can you get the exact model of that timer? That might be better for my wave maker or at least easier to program anyway. I would appreciate it if you could.

    It is an Omron H3CA-A. I have an extra with a base. Programming it is a breeze and the wiring was so simple. Let me know if you are interested in the extra.

    I would be willing to trade for frags if you want, that way no cash out of your pocket and you help me by getting some stuff in my empty tank. LOL. Let me know if you are interested in that. Thanks

    Dude, thats perfect. My wife likes softies and leathers. SO what ever you could spare would be fine. My last tank was SPS, so please forgive me if I don't know what everything is in the line of softies. I would like something with movement and color. Color is very important, really don't like all brown. LOL Just let me know.

    Well let's see here. I have plenty of purple mushrooms. I am sure a few kenya trees, I have a finger coral I could probably trim. I have a yellow leather I would probably frag out. A lot that I do have at this time has lost their color and turned a little brown due to my lights and skimmer. I am in the process of changing out my lights, and hopefully I will get one of the mega super duper skimmers from ASD next month. Hopefully will get to order it next weed. They have about a 6 week lead time. Anyway once I get the skimmer I am sure the colors will come back. All this to say, is I have a few with color now and I am sure if you put the ones that were say yellow or green in your tank they would come back as long as your tank is up to snuff. At this moment I am still working on mine. If this is not cool, just let me know what you need money wise and we can work something out I am sure.
