anyone tried to using Jebo WP40?

This is what I was referring to about frequency. Here is a time domain simulation from an LPF signal providing a steady 4V. I am of the understanding that since we are supplying a PWM signal to the LPF, you still have a frequency. The LPF smooths out the PWM signal but you can clearly see a ripple exists after the LPF.

There is no detail description of the product. As far as I am concerned, the price is just for the pump itself. There is no power supply and controller mentioned or included.

LOL
I doubt it but a quick email to the seller can confirm what's included
 
It is interesting one would sell for $75 shipped and the other $135!

Shows what kind of mark up is going on.

I just received an email that my RA Jebao cable is being shipped today. Hopefully later this week I can see how easy this is to use with my Apex.
 
look at the prices here, these things probably cost like $20 to make

and this picture shows the wp25 but I have not found that one for sale

It doesn't say it's a Jebao and they don't show the controller. It's a Chinese store selling thru the Chinese version of Ebay. And to get the $70. price you have take a $5 coupon (probably good for one pump only). Given what I've learned about EverGrow and the Chinese led manufacturing situation, my guess is somebody else is making this for Jebao and they are willing to sell to others if Jebao doesn't buy them all. Branding, and patents and proprietary products just don't happen in China. It's not the way they do business unless you are really a HUGE customer.

I filled out the info all the way to the "place order" screen and I didn't have to take a $5 coupon.
 
Wow,

The thread goes fast!
About the PWM signal. I've tried the LPF with 1K Resistor and 4.7uF capacitor, but the max voltage i could get trough it was 3.8V, so decided to go directly with arduino PWM(Wich is not stable signal), and it also worked, sending the 5V at max. So i'll go with PWM direct signal, though some people might state that there might be a problem...
I've done it, tried it, filmed it and posted it earlier.
Right now i'm building the circuit(soldering and plugin), and as soon as i have it done, i'll have the pump running.

I'll be using a pot to control some modes, like ramp and max speed, another modes i don't see the need of beeing controled just because if it runs at lower speeds they will be less efficient.

BTW, the pot its not connected directly to the va line, its connected to the arduino so it can read the input, transform it and send the signal to the pump through the PWM.

I'm working on a way to connect an LM7810 to convert the 24VDC to 10VDC to power the arduino(the goal is to use only one power suply). But it would be another project.

Its really simple, if you dont mind changing mode connecting it to your computer, the only thing you need is an arduino!
Power Supply to feed the pump, and arduino to feed the va line.

I don't think that you need to have a 0-10V power to the va line, once the guy who did it, afterwards just plugged a resistor to cut the tension in half so it would have 0-5V...

I am trying to get a arduino to run some of the Reef Angel Vortech modes to this pump. If I wanted to use push buttons on the arduino to change modes and have a lcd screen what else would I need besides the Arduino (presumably a R3 correct?) and a LCD sheild to make it happen? I would also be using the RA jebo cable they are offering... Since the Reef Angel is based on the adruino the code should run correct???

I Supose so...
I don't have an RA so i can't confirm, but the coding is C, so probably it would. But don't forget that the RA would probably have more stuff in it, i assume that it has an RTC(Clock in other words), besides the relays it uses. So the libraries might be a litle different...
I dont have an LCD... but if you would like to have the code i've made to arduino uno(r3), please pm me your e-mail and i'll send it to you. i would have posted it here(again), but i'm making some minor changes to modes, so...

But yes i supose you could make it with a pushbutton, an LCD and... to connect it, probably the harness would work, but i'm working with the native controller(my controller broke down 4 days after i started the pump) and its cables, so can't tell, actually...

The RA has modules and add-ons that may be addressed in their code which you don't have. The RA PWM module runs at 10V, Arduino at 5V, so that needs to be taken into consideration as well.

You should setup a google code repository, so you can post code there and keep it updated, and link to it from here. That way your links and references to it are always up to date.
 
OK, i took the plunge and bought one from mrtao for 57.60. I'll keep you guys posted with my experrience.
