Hi,

I have started to use simplescreenrecorder on my Ubuntu machine. I need these video's to be in a resolution of 1280x720. To make things simple I switch my main monitor to that resolution and then record the entire screen. Everything seems to go smoothly from there.

But strangely when editing the videos I find that their actual resolution is 1280x736 (!). So I have to scale them down to fit with the rest of my content.

If I open the video's in VLC and ask for the codec information it tells me this:

Resolution: 1280x736 (wrong res)
Display Resolution: 1280x720 (correct res)

While recording, simplescreenrecorder itself tells me the resolution in and out is 1280x720. So now the question is: where do the 16 extra pixels come from?

I tried encoding with the default H.246 and with MPEG-4, but that makes no difference. Any idea what might cause this?

Thanks,

Reindert

Tried sending the ValuePack panel through Elecrow standard service a few days ago and they said they can't manufacture it like this unless I pay $36 instead of the normal $10. Anyone else had any success recently?

Hi Marten,

I've noticed there is a 2B version of your antenna. What are the differences and or the advantages of this revision? Is the spacing the same as version 2?

Thanks for all the hard work!

Read the readme files ;).

The 2B version is re-tuned for use with plastic protective shells, such as the ones sold by MenaceRC and FarVew.

Hello there.
How to change the print on pcb.
Example: I want to scroll down Design By Marteen Baert.
I would also like to add the manufacturer SkyRod article.
How will I do that

You can do this by editing the Python script that generates the files.

Hi Maarten, I wanted to let you know that Lumenier is now manufacturing the Pagoda antenna in RHCP and LHCP version now. (RPSMA coming soon as well) It would be great if you could link it on the "Where to buy" section. Thanks for all your work on this project!

Hi Maarten,

If I use 0.8mm pcb what the distance between the discs should be?
The same, the actual distance +0.2mm?
There is some formula to be used?

It's not that simple. If you want to get it exactly right, you need to re-tune the entire design. It's easier to just stick with 1mm. If you really want to try it with 0.8mm, then just keep the distance the same.

hi, i'm attempting to edit the python files but when i run it it send an error, No module named 'pylab', im pretty new to coding and have only done matlab stuff, what do i need to do to get it to work? i have got ipython from the anaconda suite but have no idea where to start. thanks and love your antenna works great on my quad

You need to install a number of modules. 'pylab' is a collection of modules including numpy, scipy and matplotlib. You will also need 'freetype-py'. I have never tried installing it on Windows, but on Linux you can get all of these from the package manager. You can also install them with 'pip' if you are familiar with that. Note that you need python 3, not python 2.

Hi MAARTEN : thanks a lot for your "pagoda" antenna.- So a great and lovely job !!.- I´m wondering myself about the thinner RG405 coax cable for RG402 replacement.- Maybe it makes not so much difference.- 73,s.

It is certainly possible, but it would require re-tuning for optimal performance. It would also make the antenna more fragile.

I noticed in your ReadMe file when ordering from Elecrow to select the 1.6mm PCB Thickness, but in your instructions on the page you are very adamant about using 1.0mm PCB. I did order the 1.0mm, just thought I would point this out so you can update your documentation. Great work on the Pagoda Antenna, and thank you for sharing the plans.

Oops, looks like I somehow copied the default Elecrow settings instead of the edited ones. Thanks for telling me!

By the way, I've noticed something strange. Your 3D rendering from the simulator shows that the center PCB has the copper on the bottom side, while the gerbers and assembled pagodas have the center PCB copper on the top side. Is this normal?

EDIT: FAIL, I got fooled by the perspective of te 3D rendering. All is OK. Please ingore this comment.

Yeah, the 3D viewer has half-broken transparency support. It doesn't know which parts should be drawn in front and in many cases it messes up. You don't get that problem with opaque colors, but then you can't really see what you're doing. I've learned to ignore it :).

Recently a friend of mine sent his first attempt at PCB panelizing to elecrow. He sent something that no sane PCB manufacturer would make and surprisingly he got exaclty what he ordered with zero compliants and no extra cost. It was a very unstable panel with features we all thought were forbidden in chinese manufacturers.

So, now knowing that elecrow will make almost anything, I've decided to design this:
https://github.com/Repo-IEEEsb/DroneRacing/tree/master/Desarrollos/PagodaValuePack

I've called it "Pagoda Value Pack" and it includes 3 copies of the Pagoda Antena PCB's (RHCP for now but changing to LHCP is trivial and will do it if this works) with added breakaway alignment struts, a modified simplified assembly jig that uses the alignment struts, an end ruler to measure the coax, a stripping depth gauge for the RP-SMA connector and a template for cutting styrofoam half discs to fill the pagodas. All of that in a single 10x10 cm PCB. I've ordered an experimental batch to see how all works. Hopefully this will simplify the pagoda-making process. We're also testing styrofoam-filled pagodas with very promising results durability-wise!

Maarten,

Two questions as this is the first time I have toyed around with PCB antennas.

1. I am trying to have the PCB's done by a friend of mine here in the US and he is stating that the drill file is not included in the Gerber files. Do you know what he is talking about? If so how would I go about getting those from you? Email?

2. The FR4 needing to be 1mm is only the FR4 correct or is it the overall thickness including the Screenprint? I know the issues with dielectric speed, but you don't provide a total thickness of the board and screenprinting.

Thanks.

1. Tell him that the .txt file is the drill file. He probably wants to rename it to some other extension like ".drl". Sadly there's no universal standard for these extensions, some manufacters want ".txt.", others want ".drl" (short for Drill) and yet others want ".xln" (short for Excellon).

2. The 1.0 mm thickness is the base FR-4 material. But realistically it doesn't matter if it's off by a tiny amount, the properties of FR-4 tends to vary between manufacturers anyway. Solder mask is only ~20 µm so I just ignore it, it has no meaningful impact.

HI Maarten,

Im using the SSR for the a week now and its working great with our WOWZA streaming server via RTMP stream. however when i enable the RTMP authentication on WOWZA i couldn't manage to push the stream from SSR, i cant find a way yet on how/what will be right RTMP parameters that should includes the username and password.

Do you have any advise?

Thank you.

SSR relies on the RTMP support in FFmpeg. If FFmpeg doesn't support the authentication system you want to use, then there's not much I can do. I have no plans to add native RTMP support to SSR for now considering how much work this will be.

Hey Maarten thanks for your awsome work on the pagoda antenna.
I was wondering if there are any patch antennas that will work with the pagoda for diversity recievers.

Any decent circularly polarized patch will work with the Pagoda. I actually have a new patch design coming out in 1-2 months probably, but if you don't want to wait that long, take a look at the patches from SpiroNet or MenaceRC. Or use a helical antenna, those are fine too.

Hello, Is there a way to detect if body is sliding on another? I want for example metal part making sparks when sliding on concrete. Thank you

Read this article. Combine this with ep_body_get_xvel_local_point and ep_body_get_yvel_local_point to detect whether the bodies are sliding. Example:

var s, c, b, object;
for(s = ep_body_first_shape(global.world, body); s!=0; s = ep_shape_next(global.world, body, s)) {
    for(c = ep_shape_get_first_contact(global.world, body, s); c!=0; c = ep_shape_get_next_contact(global.world, body, s, c)) {
        b = ep_contact_get_body1(global.world, c);
        if b=body {
            b = ep_contact_get_body2(global.world, c);
        }
        object = ep_body_get_user_var(global.world, b, 0);
        if object.object_index=obj_block {
            // this instance is touching a block
            
            b1 = ep_contact_get_body1(global.world, c);
            gx1 = ep_contact_get_point1_x(global.world, c);
            gy1 = ep_contact_get_point1_y(global.world, c);
            lx1 = ep_body_coord_world_to_local_x(global.world, b1, gx1, gy1);
            ly1 = ep_body_coord_world_to_local_y(global.world, b1, gx1, gy1);
            vx1 = ep_body_get_xvel_local_point(world_id, b1, lx1, ly1);
            vy1 = ep_body_get_yvel_local_point(world_id, b1, lx1, ly1);
            
            b2 = ep_contact_get_body2(global.world, c);
            gx2 = ep_contact_get_point2_x(global.world, c);
            gy2 = ep_contact_get_point2_y(global.world, c);
            lx2 = ep_body_coord_world_to_local_x(global.world, b2, gx2, gy2);
            ly2 = ep_body_coord_world_to_local_y(global.world, b2, gx2, gy2);
            vx2 = ep_body_get_xvel_local_point(world_id, b2, lx2, ly2);
            vy2 = ep_body_get_yvel_local_point(world_id, b2, lx2, ly2);
            
            nx = ep_contact_get_normal_x(global.world, c);
            ny = ep_contact_get_normal_y(global.world, c);
            vel = abs(nx * (vy1 - vy2) - ny * (vx1 - vx2));
            if(vel > 0.1) {
                // generate sparks here
            }
            
        }
    }
}

Not tested.

Now my PCB supplier is asking whether the PCB is Single or Double Sided? Would you be kind enough to let me know...

Double sided, otherwise you will miss some pads on the bottom side and you won't get through-hole metallization.

Are there any plans for a 1280Mhz version of the pagoda ?

Quote: Matan

I built the antennas, and I'm having some performance problems.
I' using the same cable and connector you give links to, made the PCB's at elecrow, and assembles using your jig and following your video.

I think it's because of a minor mistake on the gap between the PCBs, they are about 0.1-0.2mm closer then what you specified.
Could that be the reason? if not, what else?

I intend to design a new jig that will make the assembly more convenient, as well as more accurate. (and will that will be 3d printed and not laser cut, which is where my inaccuracy come from)

So, do you think its possible to cut a notch in the two big PCBs so they will be at a fixed position in the jig? (instead of the silkscreen lines, cut three tiny notches on the outer part of the PCB and have a dimple in the jig that will sit in the notch so they will be at fixed position to one another)

Will it have an impact on the performance?
If it's OK, how can I alter the design? with what program?

If you place the notches far enough away from the copper elements, it should be fine. You can change the PCBs by modifying the Python scripts that I use to generate them. They are included in the design files.

Thanks for your antenna design Maarten.
I tryd to isolate traceroute the antenna after exporting the gerbers to have it isolated traced for my cnc.
Unfortunately i must have done it badly, i am sure the measure is off after i tryd to export them.
My SWR is way too high and only its about 1:3 at the highest frequency to get best SWR... lol
Allmost sure the arms are too short after converting.
Is it possible to have some dxf files so i can try it again? Converting gerbers to anything usable is failing here.
Got my hands on a few FR4 pcb 1mm now so i dont have to thinning the 1.6mm pcb.
Hope you can help me out.
Thanks in advance.

ps. got 2 pagoda antennas in meantime to play with from Menace. SWR seems better without the protection cover.
Tested some Depron foam between the 2 top plates has giving me a good result, hardly affect the SWR

DXF files are now included in the design files. Getting DXF files from Gerbers is really annoying, I generated them from SVGs instead.

I was wonder what makes the difference in a RHCP and LHCP with the Pagoda? Are the templates in the disc simply going in the opposite direction to change the polarization> Like a cloverleaf.

I also thought I understood from previous post that in fact the cable length creates no no issues so long as the disc do not contact anything potentially conductive.

Thanks!

Yes, the LHCP and RHCP version are just mirror images of each other. Just mirror the two top PCBs and you will get the opposite polarization.

Quote: Rotordog

One last question. Would it cause any issue with performance if you dipped the PCB antenna disc and at least part of the coax in a protective liquid vinyl?

Yes, unless it's an extremely thin layer (less than 0.1 mm). You can probably get much better results with Styrofoam, which doesn't affect the performance significantly.

Hello maarten
My name is Halim KARAPINAR
I have been manufacturing antennas for FPV systems for about 3 years. I am very successful in this regard in Turkey. And I produced the antennas you designed for the first time in Turkey. I produced 45 pairs of antennas for the 1st race of the Turkish Dron Competition League which will take place in Istanbul city on March 19, 2017 and delivered it to the competitors. These antennas are excellent.

I need help on a topic.
I want to make changes to the prints on the PCB antennas.
For that you can tell me the raw files of the antennas and what program I can open. I use DipTrace. But if I have to open it with a different program, I can also download that program.

I also want to make a small donation for you.
Thank you very much for sharing your help and design.
The producer of SkyRod Antennas is Halim KARAPINAR.

The Gerber files are generated by Python scripts which are also included in the design files. I did not use traditional PCB software to design these PCBs.

Quote: Maarten Baert
Quote: Jmscreator

When reading from a buffer, if you read more than what is in the buffer, zero is returned(this isn't the issue I'm referring to). Now I do my best to write clean code, and I make it nearly impossible for this to happen, but with sockets, and data that can sometimes glitch once in a great while, there is still the possibility for a buffer read to read outside of the buffer size.

As far as I can tell there is no bug here, you just misunderstand how buffers work. If your buffer has one byte remaining, and you try to read a type that is two bytes large, nothing is read, the error flag is set, and the function just returns a default value (0). The position does not change. So no matter how many times you call buffer_read_uint16, you will never read that last byte.

What you should do instead is call buffer_get_error after reading a message to verify that nothing went wrong. Situations like this will set the error flag, and it won't be cleared until you call buffer_clear_error or buffer_clear.

Also, as long as the error flag is set, all read functions will return zero (or empty strings in some cases).

Thank you for informing me about this! I just saw this reply today.
