Smokeless wood fire
This is a simple way to make a wood fire that burns the emerging wood gas.
You simply stack to steel pipes and put them on a grating.
The inner pipe must be a few centimer shorter than the outer pipe.
The outer pipe needs some inlet holes im the bottom part to let air between the pipes. This air will be preheated while it rise to the top and will ignite the woodgas from the main fire.

DIY Airlift/Mammoth pump sediment filter
Просмотров 56 тыс.4 года назад
A simple airlift based filter to easely clean your pond or pool. It is simple, effective and, contrary to other sludge pumps, total animal friendly. I don't know the flow volume but it seems to be more than 10.000l/h at waterlevel If you build one yourself: Please don't use your filter overnight. Newts are really curious creatures and you will have ALL of then in your filter bag (unharmed but w...

Thanks Sven. I am also a koi pond lover, and i'm also an Oberg. Eric Oberg Dallas Tx
Please do a video on your pond!
Great video and lovely pool too, Sven. It pays to be a good inventor in this field.
Wow
can you safe time just using an air stone ?
Sure, maybe you're right. Have you tried it yet?
I like 2 things on this tutorial: 1. using japanese saw for cutting PVC pipes. I was sure this is my patent :) Yeah, the finer side is EXCELLENT for this purpose, cut is very precise and clean. Next, if you are saving some cracked pipe inside a narrow hole and you need to clean the throttle by cutting-off the cracked rim. There is often no space for normal handle saw but this one with LOONG handle and flexible blade can go in. Japanese saw rules! 2. I like your filtering sock solution :) Filtering sock is very standard solution in saltwater aquaristics, people use it as cheap and robust pre-filter on the entry to the sump tank. But in the pond business this is not seen very often (stationary filters need something with higher trash capacity e.g. vortex unit), but for "rambling cleaner" it is excellent choice! Thanks for inspiration!
What were the nets you used to catch the sediment? Its not very clear in the video. Would love yo see more of your pond. I assume its a swimming pond? What size is it?
I don't know the english name. In german they are simply called "Filterbeutel monofilament Größe 2" www.ebay.de/sch/i.html?_nkw=filterbeutel+monofilament&_trksid=p2332490.m4084.l1313 Take the coarsest you can get. The swim lane is 11m long and 2,5m wide. If you use a "Schwimmstrippe" (a belt with a strong rubberband) it is more than enough.
I just simply put uniring inside the pipe 😁
I didn't knew Uniring. A good solution if you get enough air out of it
Good job ❤️👍
how come you don't have any video showing that gorgeous organic pool? i'm building mine right now and every video helps and brings some improvement
Yes. I should do that. The thing is, i will need to explain all the details why and how such a simple concept works and i don't know where to start :)
@@svenoberg4738 IOW like me, you forgot to film huh? :) Btw, great job with the airlift/vacuum thingy. It puts me in mind of a similar design concept I've been wanting to try myself :)
Good jobs
Top! Genau gezeigt wie man das mit KG Rohren macht. 👍🏻👍🏻👍🏻
Danke. 3-4 Reihen Löcher hätten im nachhinein auch gereicht aber sicher ist sicher
I really enjoyed this video! Good work and really nice pond too!
Thank you!
attaching large parabolic plastic upside-down from kitchen ware at the bottom of the siphon pipe will do the job better i think.
Yes. I tested something similar. The problem is the definition of "better". With an Inlet-Cone i sucked the gravel from the bottom but not enough from the floating particels around
Thanks for posting such great video Sven- I was wondering what material are these pipes made of?
Hi Akin, the pipes are made of PVC-U Hard Polyvinylchlorid. But it doesn't matter. As long as you have a glue for your pipe material everything works (maybe lead isn't optimal)
@@svenoberg4738 - That makes sense. Thank you
@@svenoberg4738 it DOES matter!!! PVC-U or KGK is the ONLY suitable material, the other alternatives have no chance to be GLUED, polypropylene tubing has to be hot-air welded and that requires equipment and skills. Thus here in Europe, stick to the ORANGE pipes only!!! (or black/grey for pond use but ONLY marked as PVC-U, never use grey HT tubes, they are made from polypropylene)
@@gardaloops4190 The timing of your comment makes me smile. Last weekend i tried to make one out of the grey HT-Pipes in DN75. It was a little bit frustrating :) I will use some screws and epoxy. Hopefully the new airlift can replace/add to my main filter pump.
goodddddddd..
Very informative, thanks
Superbbbbbbbbbb👍👍👍👍
Is that Bluetooth Controlled or something? I want to make one of those, with some sort of attachment that allows light to recharge it; Sort of like a Solar panel!
how you have made it make video on it
Hello.Wanted to know what do I have to the balance was? I want to do with gear motor 350w 24v electronical unicycle or monowheel (equilibrium). I just did not know how to connect gyro or Arduino.Can you please write or to shoot as poluchaetsja the whole system
Take a look at www.diyelectriccar.com/forums/showthread.php/ovaltines-segway-clone-89471.html It is the best instruction manual and source base i found. Really straightforward
how will you hold balance?
In theory it should have worked like this: ruclips.net/video/K0YiLQlxgNk/видео.html But my motor doesn't had enough tourque at low speed. So it failed :(
Very nice job
Excellent Love it!
