Re: when will Raspberry pi 4 + windows 10

Interesting link.
Never say "Never"?

Has MS noticed that the third biggest selling "PC" is a tiny SBC coming from the UK?
Have they noticed kids are growing up using them and learning Linux by osmosis?
The writing is on the wall for MS and has been for years.

Gosh, this is on a very old spec of Pi and they run really well!
Huh? Pi4 is the newest Pi.
The older Pi's only do OpenGLES 2.0, lower capability shaders.

Re: A modest (passive) suggestion

Speed controlled by USB? 4 USB ports = Pi drones?
5V at 1.2amps = 6 watts, nope not enough power for takeoff.
But old toy drone motors would make small fans.
The smallest would be the 4mm dia tail rotor motor from the RC helicopter toys?

Re: Looking for specific software

Do a google for Linux Postit notes, see what shows up.
Try to apt-get install them.

Debian might be behind so if install does not work try grabbing the source and making the app yourself.
Some stuff just works now on Pi4's.
It is sometimes just a case of no one has tried it before.

Perhaps with an i2c/SPI based motion sensor?

Bino uses OpenGL and has dual/multi screen options.

Are you using shutter glasses? I have programmed the General purpose clock output 0 on the older Pi's GPIO. If you use the HDMI clock as the source input, it might divide down and sync. With 4K the best will be 30Hz? That might be noticeable. You might have to wait for the new BCM2711 peripheral man...

Re: Think to install Ubuntu desktop os in raspberry pi 4

If/when Ubuntu ARM get ported to the Pi4 it will probably be at least 19.x not 18.x. You might need Linux Kernel 5+ and Mesa 19.2+. That is going to be newer releases, not old ones, unless someone knows how to back port. Generally it has been the Server version not the Desktop version on ARM. I thin...
