The Telegram link a few posts back seems like a stream of consciousness -- good for chatting and sharing but impossible to use as a reference.
I would start with the Wiki. The one for this software is here: https://github.com/OpenHD/Open.HD/wiki
Since OpenHD is a derivative of EZ WiFi Broadcast, you may also want to check out that Wiki, keeping in mind that some details and functionality has changed: https://github.com/rodizio1/EZ-WifiBroadcast/wiki

I agree with your observations regarding Telegram. The RC Groups format seems much better for those who want to help themselves and read about what others have done.

It does work but not nearly as well as 5.8 something to do with the chipset.
I think the record is around 40km in the air with a 5.8 setup using AC56, do a search of Ez-WifiBroadcast on youtube.

I allways try to find lightest and easy to handle material for OpenHD-Copter
My personal goal with OpenHD:
As small and light little HD-race-copter, of course < 250gr
Range about 800m
Flight time about 10min
Stable video link with RSSI and mavlink
no gps, no long range
I am close :-)
regards

That's a beautiful small setup! May I ask why a plywood frame? Is it because it is more accessible, cheap, easier to machine or lighter? All or some of the above?

Telemetry problem solved (at least partially)


Hi! I previously mentioned that I couldn't get telemetry working. As it turns out, I couldn't get it working on the FPV_VR App. I got hold of a HDMI to DVI cable (my computer monitor lacks HDMI input), and apparently telemetry works! It even works both ways on the same serial port (Omnibus F4 Pro, flashed with ArduCopter), which allows me to send RC inputs from a joystick.

Need to figure out why it didn't work in FPV_VR, or find a portable monitor/goggles with HDMI-input. Any suggestions?

Additionally, now I have to figure out how to remap the joystick inputs. The axes are all mixed up, but it seems that the joyconfig file allows you to remap them. Though I don't know how to map the buttons to different functions (as should be possible with Mavlink 2). Is there any way I can map the buttons on the controller to different inputs, such as flight modes? If so, what is the syntax for doing so.

I hope this info might help someone else struggling with telemetry!

The most important, only half serious reason:
I build to fly, not for crashing.
For flying it is more than sufficiently stable, even for harder landings. Lighter than 2mm carbon. Inexpensive and easy to work.
I also enjoy building other things besides the mainstream.

Many thanks for the reply! I wonder if plywood "behaves well" even for larger models, say 5", 8", 10" prop models. Maybe something to explore once I finish this project.

Hi
As I have described here:
https://www.rcgroups.com/forums/show...postcount=1924
I reinforced the plywood with carbon. This works also with bigger copters, as long as you don't have to survive heavy crashes.
Certainly not suitable for real race-copters.

I think a write up of how you go about designing and building these types of frames would interest many!

rtl8811au chipset (dexp wfa-601). Does not work:
telemetry
cpu boot
cpu temperature
receiver sensitivity.

Russian image Ez-wifibroadcast-1.6RC6+8812au everything works.

P.S.
Sorry. I use google translate.

I ordered a product at AliExpress. According to the description, chipset RTL8812AU should be used. But chipset RTL8812BU is mounted. And my Raspberry tells me: "No WiFi Cards detected". May one tell me if RTL8812BU works as well?

Im Sorry,

My gosh, I have messaged them several times to change the description.

8812BU is some obscure different cheap realtek chip.

Many have wasted money on them I would ask for a refund if you can.

Here is a link to the best 8812au module on aliexpress.

It is confirmed working by many people and, has extremely high quality amplifier and low noise amplifier modules.

There are some other smaller 8812au modules that will get you 100mw or so and they are only $10 or so.


#Aliexpress US $19.50 | RTL8812AU 802.11ac 5G 867Mbps Network Wireless USB WiFi Adapter 650Mw SIGE 5023L+SKY85601 for Kali Linux ubuntu ARM Raspberry Pi

Htcohio:

Have you tried changing the EXTRAPARAMS profile to extended instead of high ?
Reduced my errors and gives a visibly smoother output.
Reading up on it says it was made for streaming vs high that was for DVD ect. so I
tried it.
