Well, very cool, but....i'd subscribe if you were still posting! Sadly, perhaps 'life' has gotten in the way of KZbin. I hope, though, that *good things * are 'in the way' of YT!

So I need a 3d printer and a lathe to make this at home??

isnt this the mocs they sell on Ali express for like 4 dollars? who ripped who off tho i wonder

The impedance of this dipole is 75ohms and you need 50ohms.

I think simulated annealing is a better way to evolve an antenna than evolution algorithm... When you mix two good designs with each other it will completely throw off it's operation. Annealing just vibrates the variables... I would still do multiple generations though, but each generation should start from scratch. You still need many generations because each trial gets trapped in a valley. Every new generation goes in a different direction.

I need your help with my version of this

I started writing my own program like this... what i did is get the max value from the gains collection and used that as my optimization variable

Where can I get the pynec module? I just ran an example and all my modules work

Fa... i made it today and not work am so tired zzzzz😔😕 wy not working for my router TP-LINK 😣💔💔💔

Funny thing i had same idea to use that same wire bc it's available, but i measured it's thickness to be 2.5mm

Beautifull thanks man u solved my Problem

They sell black hot glue... it's cheap.. nice build by the way!

Nice video. A few comments for those interested. The 4nec2 program has a built-in genetic optimizer. For what it is, it is turnkey and very nicely done. The UI does allow for some kinds of parameterization. Simple math expressions are supported for sure. That enables encoding of things like number of elements, wire length and spacing, etc. However, I don't know if anything more sophisticated is available. Trig functions, for example, would be nice so that wire angles could be encoded. Quaternion would be ideal. Doing this in Python as you did is absolutely the right approach for the generality. Packages like PyNEC nicely wraps the NEC2++ backend for usability. Additionally, I'd take a look at packages like PyGAD for the genetics algorithm engine. That can save lots of programming time. Now, a practical problem for antenna designs at WiFi frequencies is the very tight manufacturing tolerances. A few tenth of millimeter in length or a degree of bend changes radiation behavior substantively. 3D printing is the way to go here. Use SolidPython package to go from the NEC2 geometry deck to OpenSCAD input. The rest of it is standard 3D print flow, e.g., STL to Cura or other slicer of choice, etc. Use copper tape on the printed plastic framework. Alternatively, glue copper wire to the framework with a bit of CA glue. Of course in either case, your GA optimization has the wire diameter as a constraint.

Hi, i broke the wire off a single plug on ipad Wifi connector. Question- looking at the wire, it seems to have inner wire and a bit of outer braid. Does this mean the inner wire connects to the very thin pin and the outer connects onto outer round clip that buttons onto socket on board? so theres 2 connections outer and inner ? do i need that outer connection or only the inner pin to make the antenna work or is the braid grounding and it wont work right without? thanks

Your work is very nice sir

Antenna Eugenics

You need 1k for inventing this genius build.

Man be specific in mm for the measures not your stupid wavelength Language

Pls share code

That was fun.. it was like I was your neighbor and I could watch but I had to keep my trap shut - it worked for me. Cheers!

Would be nice if you could share the code.

in 80s people were using cloth hangers instead of yagis on the roof, and we were laughing, until you reveled the truth

Just want to add that you need to use your yagi in the same polarization as your router, so if your router antenna is sticking straight up, you should turn your yagi so the elements are vertical. Crossing horizontal and vertical polarization results in significant attention

you certianly deverse the subscribers.

The reflector, driven element and directors do not appear right if this is for 2.4ghz.

Where do I get that ball joint?

Great video - GA’s are a lot of fun to work with, but there’s both art and science to it.

I seen this in my technic Ferrari

It looks like you pointed the directional antenna away from your house. (driven element is next to reflector witch looks like its at the house end)

Please do not use this cheap coax, it has a high signal loss and is made for low frequencies under 1 MHz.

No code?

Why not a scheme?

Looks promising. I should try that. But measurements are very difficult for me. Can you share your antenna measurements?

Good video! Two questions: 1) Was the circular reflector part of your model? 2) How does the antenna perform if you use a straight wire of the same length instead of the crazy bent one?

This is great effort but there are some major flaws in your build of the antenna. Mitigating these issues will vastly improve the performance. 1. The Coax cable is too long, this will negate any benefit you receive from the gain improvement of the yagi. 2. You seem to have used multiple adapters to convert to SMA at the USB adapter- each adapter adds to the total RF loss Also why are you measuring the performance using latency? Your latency is a function of your internet connection, which can vary independent of your antenna and signal strength. You should redo this step with dBm measurements instead. All in all this was a really good effort and I enjoyed watching the video. I’ll stay tuned for hopefully more.

What is the signal wire and what is the ground wire? I don't know much about coax, but I do want to try this project and see how it compares to a cantenna that I've built.

Cool video, man. Thanks for making it

since when dont sdr recive the 2.4 ghz band? @Electric Technic

Can you please share the code as this is what I need for my 3rd year engineering project.

this idea came from lego technic set 42039

Where can I get that sma connector

this is like the holy grail of the ham radio community

I have everything except the hubs a CV joints. I know what I'm gonna buy on Bricklink next time.

if you turn the antenna so the elements are vertical it makes a big diffrence

isnt this literally the same design as whats in the 24hr race car?

Oh, never mind. Automatically looked for the link, but you had already presented it in the vid, sowwy!🙄🙄🙄🙄😳😁👍🏻

INSTRUCTIONS, PLEASE!!🙄😳👍🏻

are you providing the printer model to the public? and thank you for sharing? and if so where?

Could you share the code on github or smth please? That'd be really helpful!

Amazing
