News roundup
- It is now possible to record video to a connected SSD or USB stick
- Both HDMI and VGA outputs now work, there are no limitations in connected displays
- A lot of different things ;)
Upgrade from original HI3536DV100 NVR board firmware to OpenIPC FPV firmware
- Install PUTTY and TFTP server
- Download actual image for NVR from OpenIPC site
- Upload this image to your TFTP server
- Turn off NVR power, connect USB adapter to your NVR UART, specify which COM port on your PC
- Go to U-Boot with quick press Ctrl+C at power on
- Execute a set of commands each line separately
# Сhanging the ip address of the NVR board and the ip address of your TFTP server
setenv ipaddr 192.168.1.10; setenv serverip 192.168.1.254

There are a lot of reviews and opinions regard this product. But I think it is not enough.
I found something really annoying about this thing when I once had one. And no one talked about it.
Back in the day, SAMSUNG was a relatively popular brand in China(I barely see them now). And they produced the product AMOLED panel since then. This thing was used on their phones for a long period, and many people had told me how good it was, but as you may know, the real decent generation of their AMOLED screen was just came out several years ago, when Apple decided to use it. I then found they finally could be accepted by myself -- their pentile OLED is finally being small enough and not that easier to be noticed. So I bought my very first Samsung phone - S23.
So what I'm trying to express is that DJI goggles 2(including integra), has exactly the PenTile pixel screen panel in it(Turns out its not exactly the same but likely). It looks just sucks to me. These pixels just keep stabbing my eyes.
Sorry DJI. I mean it. But it is what it is. I don't want to talk about the dead pixels. It all about PenTile pixels. Yes, I can also notice some flick of black out of the screens, but I think all the 1080p oled screens have that issue.
You can read more about PenTile OLED here : https://www.oled-info.com/pentile
I can't use it anymore. Maybe the next generation.
P.S.: Turns out it is something like hexagon pixels.

嗨JB，你对蜗牛数字图传系统大体怎么看？你觉得它在性能和质量方面都比DJI强吗？我在用V1眼镜并正在找一个相对紧凑的。我应该直接上G2而不是蜗牛吗？
或者再等等,DJI在2024年发布的新眼镜？我不着急。我经常旅行所以我想减少点重量且方便携带。爱听你的想法。
JB：
我不觉得蜗牛比DJI好（总体上）。我个人的看法是，蜗牛和DJI v2/vista 系统在同一水平上或者还差一丁点儿。和O3则差一个档次~
但是蜗牛有其它的很多优点比如 1S 图传，HDMI输出等。然后图传距离和穿透性也已经足够好即便可能不如DJI。所以它对很多人来说仍是个不错的选择，可以考虑。
以上是最近看见的一个对话，可以说JB的回答很实际了。
就像之前我发的一些看法一样。我做了一个表格：
关于延迟，对于我个人的经验来说，基于网络多人测试的共同结果，肥鲨HDO2模拟眼镜大约有15毫秒的延迟，盒子眼镜大概有25ms以上的延迟，摄像头有3-25毫秒左右的延迟，我使用的CCD典型延迟是16毫秒。所以我之前练习的图传总延迟是在30-40毫秒区间，这个范围我感受不到延迟。当使用某盒子眼镜和延迟较大的摄像头平头哥时我能明显感觉到延迟的增加，但流畅度不受影响。更多的设备延迟测试可以搜索网络，几个著名的UP主都有。而较快的竞速摄像头一般延迟在2-3毫秒，加上眼镜15毫秒，总延迟在20毫秒以内。HDZERO的总延迟在15毫秒左右，这也是为什么HDZERO可以成为竞速系统。

When we first setup our Hdzero vtxs with Ardupilot firmware we tend to google it first, at least that's what I have been. And there are articles that suggest to set "MSP" option to "4". But as times gone by we no longer need to do so. Just simply leave it there the default "0" and set the corresponding serial port to "42", don't mess up with braud rates and leave the default "115" and it is good to go.
Also need to know you need the newer versions of Hdzero firmware. It contains the essential fonts that ardupilot OSD use to display.
