it does seem like they ship fast IMO ..
anyone tried to using Jebo WP40?

Yep, that's the kind of crappy customer service I was concerned about. They tell you the part is cheap and then ask you to get it from Fish Street. Well Fish Street didn't make it. And if the part is cheap, just pull one or two they know are good (as in test them first) and mail them out.
I have issues with my sensor too. If I turn the lights off in the room all at once, it's dark and the pump continues to run. If I set the room lights dim, or point the sensor at the moonlights in the tank (a PITA to do) and it goes on night mode. If I then cover the sensor with my finger it goes back to day mode. The really screwy part is, if I leave the dim lights on for a few minutes and then cover the sensor (or turn the lights completely off) it stays in night mode. It's totally screwy. I tried it at the 18v I have been running it at and again at 24v and it does the same thing either way. Honestly I'd rather have a $150 pump that worked better rather than a too cheap pump that is marginal.
So I've just sent my 'complaint' to Jebao as well.

Ron, Have you ever thought about making a wire extension for the light sensor and have the sensor pointing at a more reliable light source than just depending on ambient light in the room?

I hadn't thought about that, and it's a great idea! Thanks for follow up. I'll see if I can get that done for tonight. I wonder if the resistance due to the lenght of the wire between the controller and the sensor may cause any issues? Make it to MACNA this year and I'll buy you a beer. :beer:
And it will still be interesting to see how Jebao handles these issues.

that is a really good idea .. thats what i was wondering about .. cause it might not be getting the right light into it ..

My light sensor works well. Took me a few minutes to figure it out, but when it is not getting light, it ramps the pump down. If the sensor get's light, it runs in whatever mode I have it set in. Worked well for me last night, LEDs ramped down and pump kicked into 'sensor mode'. While the lights were on, it ran the mode I had it set to. I had to mount it behind the tank for it to get enough light to say out of sensor mode though.
Hello Simon,
My tunze's are way more silent. I hope my WP-40 can be fixed.
It is firmly in the holder , I can rotate it freely, but it snaps in to place bit by bit, if you understand what I mean. But there is really no other way I can put it in there, so that's not my concern.
Btw, it also fits in the 'silent clam' of my Tunze 6065. Some noise though.

We have talked about looking into replacing the light sensor with a variable resistor or pot to see if the light sensor port is simply an off and on switch between normal and 1/3 power or can we adjust pump speed through that port. I have tried a 5K and a 10K pot (all I have in the house) but they are just too small to do anything. I figure we need to use at least a 100K or 200K pot to see a difference. Did anyone try that?

I ordered 1 last Monday and received on Saturday morning, very fast. Ran the pump only since yesterday, but I do get the same humming/vibration you have in the video. I am not sure it requires a few days/weeks to break in, but right is definitely louder than my 3 Evolution 1400s for sure.
I added about 20 inches of wire to my light sensor and I pointed it towards and a little away from my LED's and it works pretty well. I also have two WP40's running off the same sensor. I lost one when I got them and tried adding wire to the one sensor to run both of my pumps and I haven't had any problems with them since day one and it been over a month running like this.

just got mine all hooked up .. super quiet .. dont know maybe i can sometimes here it ramp up but nothing like i was thinking .. 1 is working great in my 180 got movement all over the place .. STOKED

I have been reviewing your design for a while, and I believe I am going to go with a very similar design, however, I feel it is necessary to include the LPF somehow. I realize you said the voltage was too low, but I think this can be resolved by using a different resistor.
The LPF is necessary to clean up the square wave produced by PWM. It works, but it is very hard on the DC motor. It will shorten the life of the motor without a sine wave. This is the same reason that if you run a return pump or powerhead on a UPS, it should be a true sine UPS and not a cheap one that produces a square wave or a simulated sine.

No, they are inputs. You can set them as outputs, but then they just become digital pins like the rest.

yours came with a sensor? mine did not
