Re: How to get carrier frequency of the infrared signal using LIRC

I would like to know how to read the raw data (carrier frequency, pulse, etc ...) of an infrared signal using the LIRC library and a raspberry Pi 3. My goal is mainly to extract the frequency of the carrier and the number of pulses at 0 and 1 of an infrared signal. I'm not sure how well you can do ...

Re: Confusion with /etc/rc.local

/var/tmp is a good place for that, this location persists across reboots. /var/log is better because /var/tmp just like /tmp gets wiped out at every boot and daily (based on the rules in /etc/tmpfiles.d/*.conf or /run/tmpfiles.d/*.conf or /usr/lib/tmpfiles.d/*.conf). Are you sure about that? Tradit...

Re: Pi ipv6 router configuration

Thank you guy who loves to point out that forum threads are old and it's almost a crime to wake them up.

Re: Long Range Data transmission

I'm thinking about sending a RP3 up at around 10KM. Obviously I can't use WiFi to connect with the pi, so are there other ways to relay data (data from the sensor hat, so temperature, pressure, humidity, altitude) from the Pi to a computer on the ground? I was thinking maybe VHF? Or another type of...

Re: DIY POE?

Think twice. This won'z work. As the Pi fortunately does a clock regulation, power consumed will vary. Imagine a 2Watt dissipation situation that is 5V x 400mA. Since stated above, a typical twisted pair cable has 0.2 Ohm resistance x 2. If you feed your 2 Watt consuming Pi with 10m of cable, you h...

3G/4G and GPS re very different things (or was one of them a typo). If you do need both then you may do better looking for separate devices s that will give a better range of options. 100% completely reliable is unlikely to happen, things do break or services can be interrupted.

After a while I decided to see what would happen if I forwarded port 22. This was when my router started slowly dying. To follow on from what Ernst has said.
