Re: Sensor kit to high school pi projects

You may find that this site https://tkkrlab.nl/wiki/Arduino_37_sensors covers some of the 37 sensors.

The packs seem to change depending on rain level outside the store, amount of sunlight and direction of the wind :lol:

Re: Raspberry PI 4 as Kiosk (Show webpage)

Welcome to the forum.

Just use the search at the top for Chromium kiosk - all the software you need for a basic viewer is already on the Pi.

A similar search for disabling Screen blanking will give you a set of lines to add into a text file.

Re: No Ethernet connection after reboot.

I would look at buying a decent power supplier and not a charger.

The original Pi 3B had Ethernet issues (and WiFi) till I changed to a proper supply - saved me hours of frustration :lol:

Re: Problem connecting via VNC

But if you are using RealVNC server on the Pi then you are not using open source software anyway... The server provided by the Pi is owned by RealVNC and even the Pi has proprietary software in its boot code. I think what you are asking is impossible (and yes I have had identity issues) - see the th...

Re: changes on /etc/resolve.conf not getting saved upon reboot

/etc/resolve.conf is designed to be built up at boot time and NOT designed to be edited.

To add nameservers in you could either edit /etc/resolvconf/resolv.conf.d/base (if present) or add the data to /etc/dhcpcd.conf

I’ve now moved my settings (static IP etc) to dhcpcd.conf

Welcome to the forum.

Forget emulation - by the time you emulate the instruction set and then Windows you can fall asleep quicker :lol:

Have a look at https://www.mono-project.com/ if you must use .NET (try Python - it’s worth the work).
