Re: Magnetometer Project

The coding is easy, you can have a play with a fake SenseHAT using SenseEmu, built in to RaspberryPi Desktop. Once you have the code, look for a nice sensor and just plug it in (find a module that does the hardwork for you) You could even write in on your phone using something like Pydroid3, for a p...

Re: Drone Swarm

If you start on the ground, you may want to look at the micro:bit Use its onboard sensors to get direction etc, use the radio to have them talk to each other, add other sensors and motors as needed. Stick a pi as the computer to start them all off? That's quite a few beginners projects one after the...

Re: DS18B20: Influence of supply voltage on temperature

What is the supply voltage (on both) after the cable drop? It needs over 3.0V iirc (check spec and up to 5.5V) on the Vdd And, but please do check, something like at minimum of 0.3V difference for the pulse? I doubt it would return a result of it wasn't, you'd just get ghost sensors? 5.0V is not 'mu...

Re: Running two functions simultaneously via Threading

My rudimentary understanding,.. Isn't that because the GIL is release after some very short time, hence why for I/O it's fine, because there is a long delay in getting information back. It's just synchronization that isn't good. You could use other Pythons where the GIL is not used (?) Try multiproc...

Re: General language discussion.

Isn't that the advantage of .net, you can use VB, C#, F# whichever of the language families and they are all doing mostly the same thing. Porting between them isn't so bad either.
At least that was the dream.

Re: General language discussion.

Let me start off. I dislike the ridged formatting requirements of Python. It's tough enough getting your own code to run to be dinged by an indentation mistake.

"Celeron" What I did forget wa the Pentium Dual-Core wasn't an infill for the Celeron for a bit, but a level above the Celeron. So you can ignore that. The C2D did start when you say, but these are not Celeron. https://ark.intel.com/content/www/us/en/ark/products/34440/intel-celeron-processor-e1200-...

You missed Small Basic, my son was very happy using that until he hit its limits.
Managed to do all sorts of fun things.

Pantone 18-1754 perhaps?
Visual Basic for Applications is probably my most used Basic.


And people think Python programmers have it hard with V2 and V3

Re: Which version of Phython is the default?

Both.
If you use python you get python2.x
If you use python3 you get python3.x
As you have found out

Going forward you'll want to use python3.

Things may change in the next version(s) of Raspbian and Debian change more and more code over to python3.
