DIY wavemaker group build

[cyberwollf]

Ok im at a point where my diy controller has been running the tank for a week or so and I am very happy with the results.  I would like to offer DIY wavemakers.  These work great on the cheap korillia Evos or any other 120v powerhead that doesnt chatter on startup.

So I need to know how many people would be interested.  I think parts and labor can be kept <=$15

You get an assembled circuit board with 6 wire leads. 2 for +-5v, 2 for +-120v, and 2 hot outputs.  If you are wanting to run more than 2 powerheads we can work something out.

This will be controlled via a twist knob to control amount of seconds between switching.  From very quick to around 15 seconds.

So a populated board with twist knob and 6 wire leads.  Any interest? cheap and simple

Any other info they'll need JD? FYI it'll be a 555 timer, triacs, optoisolators, RC, and a pot

Note to self:

100k pot ATP-100K
470 uF cap 470R16
LM555
opto MOC3022
HTA06-600
PCB-46
S81250
DCSID
DCJ-21
TB-3
LCAC-194

32 seconds max cycle time with  100k R2 and 470 uF cap

I am in, and if you need help with assembly I can help aswell.

[stickboy_107]

I will take one.

[cyberwollf]

I will take one.

You better! I started this because of your whining lol   

[HUNGER]

could u have them wavemake during the day and off all night?

Yea just put the 120v line on a timer like you would lights.

[HUNGER]

o ok

[Reefinmike]

I'm in, however, I think between 10 and 30 second range would be a bit better if possible.

[slandis3]

Wes do you know if this will work on the older korillia's? If not I may need to get some maxi mods.

After doing the math on the resistors I came out with a 30 second max cycle. You can adjust anywhere from superfast to 30 seconds between switching. Just twist the knob

This will basically be like flipping a switch on and off to you powerheads. If the pumps don't chatter or startup backwards it will work. I just throw out the Evo name becuase that was one of their selling points. No chatter and a braking system that allowed wavemakers to be used. Just plug and unplug it every 15 seconds for awhile and see if you are happy with the results

I know my nodded maxis wouldn't work. They usually needed to be brought to the surface to be restarted

Wes, The 555 doesn't need a -5V, its needs a ground.

[Midwest Express]

Count me in!  I would love one!

[cyberwollf]

That's what I meant but was too lazy to type gnd.

[Midwest Express]

Just wondering, but will this work on maxijets?  I know they aren't controllable, but if this is just an on/off controller... shouldn't it work?  I have never used MJ's before.  I have just had the original Koralia's.  I can't use them I know cause they cackle when they start up.  Well my #2 does, but my #1 doesn't.

[jeblin]

I'm in for 1...maybe 2 ;-)

Just let me know when you need the money!

Thanks!

2x Jeblin $20?

I couldnt tell, some folks weren't very specific if they infact wanted one, let me know if I missed you

Also, looking around I think i can offer an "Upgraded model" for $20 This will include a 6 foot AC power plug, an enclosure, sockets for both powerheads to plug in, and DC plugs.  This version will pretty much be plug and play you would just have to supply a >5v DC supply (old cell phone or printer charger)

[Coral Squad]

i am intrested in 3 $20.00 models

[HUNGER]

no im good i have turn on off my power heads but they chatter

[TechGuy]

How a many amps @ 5V? Most chargers are 200ma or less. Unless you have a BlackBerry, Moto Q, or other smartphone charger.

Way way less than that. 5v is just to run the 555 timer and bias the Triacs. It's just cheaper to use it that way instead of building a rectifier onboard. Most people have tons of old chargers laying around. And there will be a 5v regulator so your charger can be anywhere from 5-12v DC

[jeblin]

I'm in for 2....of the DELUXE models ;-) Just let me know when you need the cash. I might have some old blackbery chargers laying around if someone needs one.

I would like my one to be the "Upgraded Model" please!
