Re: advice from anyone with case printing experience

As above. Base your design on Thingiverse designs. I've not edited a lot for 3D printing, but some 10 years ago I did use TrueSpace and some 3d programs for various things. and I did use to program in G-Code for micro-machining. Unfortunately, a lot of 3d printing is trial and error, so do find some...

Re: Release: Multiple 64Bit OS 3bplus desktop&lite

I still like and do call it Raspbian x86.

It's easy, short and you know what desktop you'll be getting.

Simples for me, like many they don't care of the underlying stuff.
It's a brand name for their look and feel of OS.

Re: Ambitious beginner project

It is the language, but use Python3 as it has replaced Python2 style.
Python is built in to Raspbian.
On the desktop there is
IDLE3, Thonny, Geany or text editors...
Have a play.

Re: Ambitious beginner project

Also look at Python3, mainly as you'll have a lot of help.and informational and web search guides to use it. C will be out there, but there tend to be fewer unless you can port from Arduino setups. C# is not common on the Pi unless using it with WindowsIOT as it's operating system (along with a PC a...

Also you should only need to forward ports if you are accessing from outside of your own network.

Re: Why does the RPF care about how many desktops I have ?

Is there a way to merge the updates somehow?

Sounds complicated, but a method to reinstate the modified setting but leave the default settings not changed but maybe updated would be nice.
Also hiding them in a hidden folder doesn't make it easy.

And CodeClub and CoderDojo being wings of RPF.

RPF need to pay for that somehow of which the majority of it is free for people to use.
(Even all the RP Press is free to use)

Of which it seems none/negligible come from the cost to use a hardware MPEG2 decoder.

Use your SenseHAT to get the level. Use GpioZero module to control the motors. (Get some small cheap low power motors to do the testing with ?) Workout your control and feedback loop. Connect the big motors. Of course you'll need to make a way to ensure the SenseHAT is level with your floor too. Sen...

Re: Pi 3b , undervoltage, usb, 5v regulator

It could be you are close to the maximum current the Stepdown/cells can provide and on adding the usb, the extra power draw of turning it all on and powering the parts on the other side is causing the stepdown's voltage to drop. Have you measured your actual voltages on the 5V/GND line with and with...
