Re: Can you call a url from a python script?

I have something like this in my crontab to turn on lights around early morning (if still dark) and on again near sunset. It also turns them off 1 hour after sun rise. I turn them off at fixed times via other crontab lines. 30 6 * * 1-5 /home/pi/lights.sh NIGHT HEX242430 NIGHT ON 0 8 * * 1-5 /home/p...

Re: Raspbian/SSH security

You could also hide it a bit more by using "port knocking" but to do it you also need client side software that supports it.
Remember though, it is only adding a bit more obscurity.

Experimenting with new lib6c on Raspbian Stretch

I have a system running on Raspbian Stretch that, since an update to it, is running into an issue that 1 or 2 others have, in the past, said is related to the version of lib6c. So - I'm tempted to try to install (or maybe build and install) a more recent version of lib6c. I know that installing a ne...

Re: updating fails

Looking at one from Nov 29th on an RPi4 ... I see a very different style of content.

The recent one that I picked up has lots of "alias" records like

Code: Select all

alias symbol:ieee80211_chandef_to_operating_class cfg80211
but the older one from an RPi4 has no mention of "alias"

Re: New Raspberry Pi 3 B not working w/ new 7" LCD

A quick easy test to rule out some possibilities would be to connect the RPi to a TV via the same HDMI cable and see if that works.
If it does not ... try a different cable.

Re: Power station for PI4

Also ... Pi4 does not need the full 3A for itself.
So if you are not planning to add power hungry USB peripherals to your Pi4 then lower power is fine.
See the specs for more detail.
