Raspberry Pi used to steal data from Nasa lab
A compact experiment aimed at enhancing cybersecurity for future space missions is operational in Europe’s Columbus module of the International Space Station, running in part on a Raspberry Pi Zero computer costing just a few euros.
A few? Somehow that feels like an understatement for a 27 euro board.a Raspberry Pi Zero computer costing just a few euros
So flat countries aren't normal countries? Haha. I think there is some truth to that. In NL, the GSM network is optimized for the flat land. It takes fewer cell towers which reduces the cost for the operators. Voice works up to 1500 feet. SMS can be used up to 2000 feet. I'm afraid it won't be any different for 5G.In normal countries with hills, coverage at 5000ft is certain. I am unsure if that is the case in NL. I would assume that it probably is.
The idea is to stream complete cross-country flights from start to finish. These flights cover distances up to 750km or even more. So I would need continuous internet access, even when crossing the border with Germany. I am not sure whether that prsents a problem by itself.You could always have a base station. LOS is probably likely most of the time.
That's a bummer but good to know. I thought the Pi's would be excellent for encoding video. FPV drones use low res camera's and broadcast an analog signal. Converting the signal to digital already causes to much delay to control a FPV drone.The Pi can't encode video very well. This is probably going to be your main problem. Look at FPV for drones. That would use similar technology.
Is it worth it, being live? If you "just" record it and put it online after the flight, it might be enough.
Haha. But that's an important point you're making. I envision the end result as a little box without buttons and displays. Maybe a LED indicating power. It should boot and start doing its thing.I don't like to be hit by a glider whose pilot was figuring out why the TCP/IP stack of his RasPi isn't fully functional
I fully agree. It would be very nice for enthusiasts to watch live how the field of competing gliders do their thing.As a spectator at gliding competitions, you only see the planes leave, stay away for many hours and come back (could be midnight when the arrive with a trailer). You don't even see a start. Imagine watching F1 by only seeing the formation lap and podium ceremony.
But what if you would have a micro computer, powerful enough to stream video and sensor data and interact with a back end? That opens up new possibilities.
Yes, that's what I learned from you and after following Kuddel's link. I thought the Pi4 would be able to do such a job. My search led me into the world of FPGA's. That's definitely not going to be my thing..You are somewhat underestimating the resources required for live video encoding.
There are a couple of practical issues with the use of smartphones. The device needs to be secured tightly. In gliders, there are usually some M5-bolt attachment points on the sides. In case of an emergency, you need to be able to release the canopy and jump without getting entangled in wires. A smartphone will need external power, and it's low weight will probably make it shake all the time. It will also be difficult to aim it at the point of interest (I'am thinking of a headstrap for the main camera which connects wirelessly, and a 2nd camera inside the device facing at the pilot). The thing with smartphones is, that you'll eventually start messing around with it. The acceptance of a device without any user interface will be much easier.But... what exactly speaks against just using cellphones?
Do gliders carry transponders? Would it be possible to interrogate these somewhere(GoogleEarth) and make a realtime display of the relevant aircraft?
N.
I think I will buy one, but this time without a plastic case.Every time a new Raspberry Pi is released there are mutterings about the thermal control of the new board. But this time, it looks like it might well be necessary to add some passive, or even active, cooling to the Raspberry Pi to keep it from thermally throttling if it is under heavy load for extended periods of time.
This case keeps the 4 cool:I think I will buy one, but this time without a plastic case.
