Missing an update to this video, is there any? Have you had any chance to try this one out more? I searched your channel feed but couldn't find anything more. Hope you can do some more testing and reflashing perhaps. I'm thinking of getting a clone like you, just wondering if its worth it. Might be if you have any more video material on it =) Thanks!
I was trying to read the Rob B comment that you showed in the video, but it looks like it was edited and the very useful and informative info is not available to us. Is there anyway to give us access to what he said ?
grandmas and eggs Julian but thinking about the heating of the video overlay chip it appears no solder was used to bond the chips heatsink to the board. Maybe try adding some solder paste to get better thermal contact could be an option. Both of my boards get warm but not alarmingly hot.
Thanks for the acknowledgement Julian. You will find once you have Ardupilot set up and flying then control is very simple. As you said to truly master the piloting aspect then a simpler control unit like the one fitted to the Hubsan is the best course. Should you progress to something more hard core then the Naze32 flight control board is one of the best for fun flying. It is not as capable as the Aurdupilot for automation but eats the Ardupilot for stability and manouverability. Naze32 multirotor flight controller (part 1) One last recommendation. For an excellent RC system look at the FrSky Taranis. Open sourced firmware equal to any of the big name brands and well made hardware. FrSky Taranis Review (part 1) Both are available from boltrc.com/uk/ Regarding the split supply for the minim board. The concensus these days is the dual supply is more of a hinderance than benifiet. The original idea was to provide a convenient source of 12V for the typical CCTV camera. Any noise introduced by the motors can easily be killed with a LC filter on the 5V feed.
Great video Julian, very informative (as always). One thing about the Hubsan though, while it CAN be a good trainer (I have two of them) you are going to need a good supply of spare parts for when you crash (as you will :-) ) quality control on these things is not great and I have had one arrive dead out of the box (the motors fail very easily after a couple of knocks.
The problem with those tiny quadcopters is that they tend to have a very simplistic flight controller which makes them near impossible fly. With some practice you can eventually get them to sort of do what you want. A larger copter will generally have gyrostablizers making them a totally different type of flying experience. As an analogy, you're now learning how to use a cheap skateboard to get experience at driving a car. They both have 4 wheels, but that's about where the similarities end. More expensive copters will also have stuff like hover mode which makes the copter stay in a spot in the air without you touching the controls. And then there's the flight contorller like the ardupilot which has GPS and allows you to preprogram a flight path and the coptor will follow the waypoints. As far as the OSD goes, that copter is simply too lightweight to carry a camera, an ardupilot (or whichever flight controller that has all the info the OSD can display) and a transmitter for the live video+datastream.
It looks like MAVLINK is actually UART protocol, but what data it sends? I am asking, because I want to put on screen my own telemetry by another arduino (pressure, altitude, compas, etc.). It will be good to know what data exactly it expect (which format) so that it may be used for experimenting. Thank you for this video. EDIT: By format, I mean for example: alt 123, spd 40, and similar sentences, or maybe just numbers in some order; 123, 40, 565, 1043002... I am guessing that MAVLINK protocol acutally giving specific data, but... Do you have some guide to this protocol? I know... I have google, but you have experience. Thanks. EDIT2: Found something, but very, very complicated: pixhawk.ethz.ch/mavlink/ This is whole protocol, but did not found anything about specific 'heartbeat' commands.
Interesting to see the DP7456, maxim have started to discontinue the MAX7456 so I guess it makes sense some Chinese(?) company have cloned it. There's not that many alternatives for that kind of chip out there
You should run the video overlay chip with 5volt supplied by soldering the two pads on the board And don't run the 12 volts in... the overlay chip will not heat up as much.and you will get a longer life out of your board...

+Chris Fredriksson No, but I may return to this when some FPV transmitter and receiver stuff arrives in the post soon.
+Julian Ilett Sounds great! =D

True, it didn't look like the chip was properly bonded to the board, but the heat did seem to be getting through to the copper.
What is that nigty green pad you always have under your projects?
So, manned flight soon, then space...what is the timeframe for Mars landing Julian?
Thanks for the acknowledgement Julian.

Thanks for the tips! Can anyone help me figure out how to wire this osd to my fatshark pilot HD and my simplepdb?
This board has built in GPS?

wat it the next vid on this

i cannot believe, i paid 50$ for this at 3d robotic. we chould give more promotion to this video
ohh ohh can't wait :))
Purple... very osh-park-y
Very "Jimi Hendrix". Haze to come later. ;-) "Let Me Show You How it's Done; You Know What I'm Sayin'!" "YA! Get on with it!".
Do people like this? I am going to sell some at good prices.
