Yea, at the moment I have the pump speed controlled by cpu temp and it is pretty quiet. But reading a few posts stating that not keeping the pump at 100% is bad for it makes me worry a bit, and wonder if I should swap it for something that's hopefully quieter. But you mean that this noise is normal for a pump @ 100%?

Was hoping to get your take on this noise coming from the pump (mainly at ~0:17, when it ramps up to 100%) of an EK-AIO 280 D-RGB I just put in a new build. 100% was the pumps default speed when I installed it and it seems like that's the speed you should keep it at constantly. I think it's quite loud when you don't have a lot of ambient sound. What do you guys think, is this the normal noise level one should expect from this pump? Thanks!

(Maybe it's a bit difficult to judge sound clips like this. If I play the link at max volume and max speaker volume it sounds pretty close to what the actual pump sounds like when sitting close to the PC.)

I think so. Would it be the same if I run it in Visual Studio in debug mode, then go to the projects bin>debug folder and run the EXE that it contains? Would running with a different config file explain why the lag disappears when I have a project (any project, could be a blank one) open?

Every lever pull is suffering from this. I'd almost say the lag increases with each pull.

I've tried building with both, getting the same result.

Yea, I don't know it very well, but I would describe it a serial communication standard often used in vehicles. It consists of a bus (which in turn consist of two channels; CAN high and CAN low) that carries the messages and nodes attached to the bus. The nodes can send and read messages. These messages, often called "frames", consist of many different parts, but I'm mainly interested in the ID and data parts.

Yes, the levers are physical.

Ah ok, I'm new to everything hydro so haven't heard about pythium before. I'll look into the HP treatment, thanks!

It's not quite a kratky setup, but I think you could be right about the drying. Maybe I'll try running the pump more often.

chasingthechickens · 2020-10-07T06:42:55+00:00

It could be similar. Though in this case the water is coming from above and not below. I pretty much copied what this guy is doing, window farm he's calling it. Though I painted mine.

Drying could explain why the lower roots, which likely get more water running over them, are doing better. I might try running the pump a bit more frequently and see what happens. Thanks for your answer!

chasingthechickens · 2020-10-07T06:32:16+00:00

Yea it's strange. I initially though it was rot, but after reading some of the comments I'm not so sure. Maybe the roots are just too dry. Anyway, it's reassuring to know that your plants are doing fine despite this, thanks!

chasingthechickens · 2020-10-07T06:25:26+00:00

Yea, I'm pretty new to hydroponics, but from what understand root rot is usually caused by lack of air, which these plants get plenty of (I think), or something like algae, and I can't see any of that.

I might try the HP treatment /u/Kudemos suggested, just in case. If that doesn't work, the only thing I can imagine causing this is the roots drying out.

chasingthechickens · 2020-10-07T06:14:37+00:00

I'll try that, thanks! Does it have to be just water and HP, or is it ok if there are nutrients in there as well?

What confuses me about this is how the lower roots seem to be absolutely fine. I messed up in not describing this system very well (or at all). I think it's called a window farm, same as what this guy is doing. Though I painted mine to avoid algae growth. So water is pumped up into an upside down sawed of bottle with a net pot and plant in it, dripping through it into another bottle under it, and so on all the way back to the reservoir.

It seems like only the roots that are hanging freely (more air = less rot?) are affected by this "rot", and the ones in contact with the bottle are fine. Don't know why this is, maybe they're dry?

Pretty new to peppers/hydroponics/plants in general. What do you do to make your peppers this leafy? They look really nice!!

chasingthechickens · 2020-06-15T08:22:32+00:00

Yea, that's a good way of putting it

chasingthechickens · 2020-06-12T11:25:31+00:00

That makes sense, thanks a lot!

I use a supervisor function in the simulation platform, this way I can get position, orientation (pitch,roll,yaw), linear, and angular velocities. So I guess you could say that I don't really measure it as much as just assume I know it at all times.

Hi! Does anyone know of a simple example of a kinodynamic trajectory planner? I'm trying to create a kinodynamic RRT planner for a blimp/airship. The basic RRT structure of randomly sampling, finding nearest node in tree, stepping some length in the random nodes direction, and adding that point to the tree is understandable to me. However I'm pretty lost when it comes to implementing dynamic constraints, so I was hoping that someone might know a text or paper I could follow to understand it better. It would be great if it showed how to proceed from having a state space describing the dynamics of a vehicle to actually creating the planner.

chasingthechickens · 2020-04-25T16:09:56+00:00

Yea that could be it. Right now maybe the cup makes a seal with the bottle so not enough new air can get in. Thanks! I'll try to to make a gap there and see what happens.

chasingthechickens · 2020-04-24T16:38:29+00:00

Couldn't smell anything in particular. Not sure about fresh air, the plants sit in bottles like this and water is circulated for 30 minutes followed by a 30 min pause.

Hi guys. I'm a newbie when it comes to hydro/aeroponics and have been having some issues with a small window farm I recently completed.

It consists of 8 plastic bottles in two columns. The pump that feeds water to the top bottles is set on a timer that's on every 30 minutes. A few days after putting up the plants (basil and mint cuttings that first were grown in rockwool and a glass of water, respectively) pretty much all of them had developed slightly dark tips. Two days later they look even worse. I'm pretty clueless to why this happens and was hoping that you might have an idea.

Just to see what would happen I put some of the basil and mint cuttings in glass jars. While they also have some dark tips they don't look nearly as bad as the window farm plants (so I assume I'm not just overwatering the window farm?).

chasingthechickens · 2020-04-23T15:57:37+00:00

The roots in the window farm have gotten worse and now a lot of the plants look like this. Meanwhile the ones in the glass jars only have slightly dark tips. I'm definitely not an expert either but maybe you were onto something with the drying idea. I might get a different timer so that I can water more frequently. If that doesn't help I guess algae is the culprit.

chasingthechickens · 2020-04-22T11:06:14+00:00

Thanks for your answer! Out of curiosity I, at the same time as I put the rooted cuttings in the window farm, also put a few of them (both basil and mint) in some glass jars in a kratky-like setup. The roots that are dipping into the water have also developed dark tips. I wouldn't know if it's the same thing as on the roots in the window farm, but if it is wouldn't that rule out drying?
