Re: aeroplane live feed to ground

Hmm sounds like an interesting project. What sort of aircraft are we talking about here? I am just guessing but if we are talking full size aircraft which come under CAA regulation then red tape is going to be a nightmare. Recording a video from on board an aircraft obviously happens all of the time...

Re: Wifi Aware

Nope because the hardware needs to be "certified" and the software never made it beyond android. It's a poor standard with even poorer uptake.

Re: Where are the DTBs for Raspbian kernels?

Raspian is the official pi OS and is developed by the foundation. Have you had a read through the official kernel compiling guide? If you follow it to the letter it works just fine.

As far as I am aware, the whole assembled unit would require testing and certifying but costs would be lower if built from pre-certified components.

Hello everyone, I'm currently doing an embedded project on the Rapsberry PI 3B+. At first I wanted to try out Windows 10 IoT Core but since there's no stable version of the OS for R3b+ yet, I ran through in some troubles. I'm now considering to give Linux a chance. I'm thinking of installing an ima...

Re: Clarification on using a 2 lead 5v fan

Never had a problem using a fan at either 3v or 5v. Use 3v for low speed and 5v for a higher speed.

Though those nuts securing the fan would concern me, have you ensured there is no way they can make contact with the board?

Re: DS18B20: Influence of supply voltage on temperature

I would go with 5v myself. To test the accuracy I would use a separate calibrated temperature probe to compare the results. But it depends on what you are trying to achieve and to what accuracy you are trying to measure.

Re: Adjusting system time on daily basis

I maybe wrong but I would have thought just restarting the ntp service would cause it to resync the time. Setup a cron script to run it daily.

sudo service ntp stop
sudo ntpdate -s time.nist.gov

Re: IP Camera interfaced with rpi consuming internet data on large extent

I agree with what B.goode has said, streaming video at decent resolution and framerate requires a lot of bandwidth. Every scenario is different but roughly speaking for video streaming it breaks down as follows.... Low quality video is very low-quality. think 240p or 320p. Low-quality settings will ...

Hi, I have never used webmin before, but looking at your screenshots you appear to be confusing mount points and folders. So in your first screenshot, you are showing that you have a share called "Data" and the directory being shared is "/mnt/data". Essentially this is saying share the entire partit...

Hi, I have never had much look with the USB boot either. I personally find SD cards to be highly reliable, but obviously depending on your Pi usage your mileage is going to vary.

Re: Boot order: change so USB is tried first

For stage 4, it doesn't seem like Raspbian automounts the SD card so I'll have to have the script do it. The problem is finding the name of the boot partition. It is currently /dev/mmcblk0p1 as it has been every time I've looked in the past. Will it always be so? Yes they will stay the same.... mmc...
