Re: Is There Screenshot software for Raspbian [NOT SCROT]

I find it easier to access the RPi remotely with RealVNC especially if annotations are needed. - Use [Print Screen] (whole screen) or [Alt]+[Print Screen] (contents of an open window) - C&P the capture into photo editing software of your choice. - Annotate and then save as JPG or whatever.

Re: Running a website internally offline

Follow any recent tutorial on how to install Apache or a LAMP server on the RPi. Do not forward ports in your router or do not plug Internet connection into the router. Any device on your local network will then have access to your local web site.

If you then click on that boarder, the application is restored to the screen. Also I have multiple desktops enabled and get a similar issue. The invisible boarder of a minimize ...

Re: Composite too intense for CRT?

I'm using NTSC. I was told that the PI could potentially mess up CRTs because of how it did composite. No. You will get the normal low quality, low fixed resolution with jittery hard to read text and a headache after 5 minutes, but it will not mess up a CRT. Composite is a bit better on a LCD type ...

Re: 5V relay board not working with Pi 3

Don't use the GPIO.cleanup(). That is likely resetting the GPIO too quickly.

Or put a sleep statement to delay for a few seconds before using the cleanup.

Please edit your post and use code tags [</>] so your code looks like this:

Code: Select all

Re: 5 Volt connections to Pi 3 board

For 5V you can solder to test points labeled PP1 or PP2.
Powering from those points is the same as powering from the micro USB.

For ground PP3 or PP5 however, I would solder to one of the port shield hold down tabs at the corners of USB, RJ45 etc. Much more robust then the PP points.
