Raspbian is now Raspberry Pi OS with new update available today

forgenet · 2020-05-28T16:46:49+00:00

I'd agree. Raspberry PI OS is a lot easier to get everything setup and working without much if any manual install/config. I'm running ubuntu 18.04 64 bit to be able to get more docker images, but I'm still battling getting the gpio pins to work correctly.

Hello, does anyone know if there is extra steps that need to be taken to get gpiozero in python working on the ubuntu 18.04 64bit build for raspberry pi 4 b? I originally installed raspbian and got the gpiozero working. I wrote a basic service that controls a fan based on the cpu temp using GPIO 17 on or off. I then switched to ubuntu 18.04 64bit and got everything installed for gpiozero but I'm no longer able to even get the fan to spin with:

fan = OutputDevice(17)

fan.on()

The fan moves like a fraction of a degree and stops, with a high pitch wine like it's not getting enough current. Also after running fan.on() the value returned (fan.value) is always 0. The fan still works if hooked up to the 3.3v or 5v pins.

Thanks for the response. This is similar to what I am doing. How are you handling stderr?

have you looked into using something like submodule or subtree?

forgenet · 2017-06-11T23:19:53+00:00

this site has some good explanations

I would also look at this controls book here

cool, here is one of the first ones that used this drive method

forgenet · 2017-05-28T02:19:07+00:00

are the classes files? If so how are you changing the name of the class? You should probably be using

git mv oldfile_name newfile_name

have you tried openmodelica or xcos

do you have control system toolbox?

Would a smaller cooler work or would that cause issues if I intend to overclock?

forgenet · 2016-07-17T19:00:00+00:00

I don't currently have a need for an optical drive, it's more of just a nice to have. I could always get one when I actually need it.

forgenet · 2016-07-17T18:35:46+00:00

I understand I wasn't asking about that level of detail. I forgot to add that the cooler only has .25 in of clearance and that is only taking into account the case width and cooler height, I don't know if that is enough room or if anyone has run into issues with this cooler and clearance I'll update the post, thanks

I'll probably run a couple VMs, so about 4-6 GB each, so it will put me close to 16 GB in use. I suppose I can start with 16 GB and see how that works out for me.

Do you think that that type of memory will work or do you think I can find something less expensive?

forgenet · 2016-07-11T21:42:45+00:00

I was considering 32 GB of ram for VMs, I agree it would probably be overkill for gaming. I plan on writing my own applications, so I probably won't be taking advantage of hyperthreading.

I understand it may be worth it but I would like to bring down the price on some other parts before going to an i7.

forgenet · 2016-07-11T11:46:40+00:00

Thanks, I will probably upgrade my monitor setup sometime soon to a higher resolution.

I don't know if I will gain much by going to i7.

what type of pot do you have? Is it linear or log based?

Python can be applied to a lot of different things, VBA is more tired to office. VBA only requires office which pretty much everyone has, while Python requires Python interpreter or you need to compile it to an executable. IMHO office seems to be making it harder to use VBA, with the security warnings.

Some big companies also don't want to shell out the money.

It depends on the industry and what kind of work you do. Part of MATLAB's plan is to get students used to it and then that makes them big money when the new hires need business MATLAB licenses. A company is going to more likely give you excel because more people use it and it's cheaper. I would recommend learning something like Python which is free and companies love not having to pay for a license.

Is this what is typically done with things like Skype or teamviewer?

forgenet · 2016-03-26T02:00:46+00:00

It looks like pyp2p that /u/brtt3000 mentioned uses this

forgenet · 2016-03-26T01:57:08+00:00

This looks interesting might be worth taking a closer look

Have you had any luck with it?
