Kelsey Ferland, my father lives in Mississauga, so I came by a few times. One time I went by the lake at Port Credit, and I saw a DJI Phantom going by. I think it's fine there since, you are over 9km from Pearson…"

You don't have to use the standard transmitter/receiver. The flight controller on the drone has a few channels as input and control, the input is usually PWM. Normally those input channels are…"

"If you don't want to open the GoPro and risk damaging it, there is a way to control it using the HD bus port. If you google for "gopro hd bus", you can find a lot of sites showing how to control the GoPro using the HD bus, for example:…"
"This is really cool. But the idea to make a quad with fully 3D printed wires is not a very good idea. It will work for connecting the main board with receiver, GPS (or other low current parts), but connecting the motors is not a good idea. The…"
"So then it's a helicopter...
The difference is that instead of wasting energy on converting mechanical energy to electricity (plus the added weight of an electric generator), and then back to mechanical energy through the brushless motors, you are…"

"Instead of 4 gas motors, why not take the concept of a Stingray 500 with one gas motor at fixed RPM with direct drive to propellers, and have the variable pitch controlled electronically.
Much more efficient than converting mechanical energy to…"

"I had the same idea, but I don't have time to work on it :(
To add to the sensors, I would add GPS, and barometer as a must. Optionally I would also add optical flow sensor, and ultrasonic sensor.
It would be nice if you can integrate (develop) a…"

"That looks to me like somewhere it's buffering the frames, and it won't release the data until the buffer is full. Maybe we should find out where this buffer is; maybe if we could find out the size of the buffer, and work around that... like to…"
"Hi befinitiv,
I am really new to RPi2, and to Linux. I wanted to increase the power of my transmitter, but I found the instructions a little difficult.
For example, I could not figure out what section(s) I have to do in here:…"

"Inside my building I get about 5 meters... Too many walls I guess. But I am using the antenna that it came with, and i am pretty sure that befinitiv said he is using a custom made antenna."
"I am trying to figure out how the data gets sent using befinitiv's solution? because I don't see any port # anywhere?
If I want to add more data (for OSD), how would I append the data to the stream? and how would I pick it up on the receiving…"

When I was testing the video transmission I noticed sometimes the delay was huge! 10 seconds or more... is there a way to purge ALL the data as quiqckly as possible (on the receiving side), probably in…"

"The hello_video program deals with encoded data stream, unless there are some APIs (similar to raspivid). I could not figure out at what point the data is decoded.
But... when I searched for raspivid source code I found it here: source code

"I looked through the raspivid parameters, and I saw the annotations, so I tried it and just did -a "testing", and it works, it sends the video with "testing" text on top/center of the video.
So, if raspivid can put text on top of the video, this…"

"So, I finally got the TL-WN722N cards, and I got it to work. The problem for me initially was that the delay was huge, about 10 seconds... but I changed the script in tx, for raspivid I changed to -b 2000000, and then the delay was minimal, but I…"
"I see you updated the script on your Wifibroadcast page :)
