L298n motor driver with Blynk

by TheJadeRabbit

Hi, I could use some help with getting my project to work. What I want to do is control 2 DC motors with an L298n driver and a Raspberry Pi 3 from my phone via Blynk. I also want to control the motors with the joystick widget in the Blynk app. I got my Pi connected to my phone over wifi with Blynk, but I am having trouble getting the Python for the joystick to control the motors with the driver. If you could point me in the right direction it would be much appreciated.

Detecting read from g_mass_storage

by LeatherWing

Hi all!
I have a project that I started with the MagPi USB flash drive article here with a few things modified. (https://www.raspberrypi.org/magpi/pi-zero-w-smart-usb-flash-drive/) File share works great. The USB is read only but for my needs that's perfectly fine.
What I would like to do is trigger an event every time the storage is accessed via g_mass_storage. In my case trigger a camera to take a picture every time a part of a file is read by the host device. This would be used to create a time lapse of an SLA printer similar to the way OctoPi works. The printer only seems to read one layer at a time so using that as a trigger would be ideal.
The MagPi had a watchdog event for every time a new file was added by Samba, but in my case I need to trigger based off a read of the modprobe g_mass_storage device.

Database sharing on a WLAN

by ljbrumfield

I have a few pi's running as webservers on a local network. I have an outdoor air temp/humidity sensor that I would like to use on one pi and share the data with the others. Any ideas?

OctoPi or OctcPrint?

by NaloMeliful

Which cephalopod do I need: Octcpi or Print?

I just today received my RPi3B+ and am somewhat patiently waiting for Raspbian to install. I only have one printer that I want to monitor.

Thanks for your advice.

Hi all, has anyone had any experience with getting ARLO to talk to PI via IFTTT. I'm wanting to make my PI "bark" (play a sound) when it gets motion events from my ARLO cameras via IFTTT.

I have and idea is that if 1 of my Arlo cameras outside my house detect something that my PI could play some random dog noises making who ever is outside think that I have a dog running around inside the house... I've got a few PI's already one is a PLEX receiver and the other a RetroPie, so have some experience with them, but no PI programming experience yet, thought this would be a simple project to get me started in PI programming.

Versions of RPi 3B+ - does it matter?

by NaloMeliful

I'm looking at the RPi 3B+ and see different versions or flavors such as Vilros, Element, and the Original from Raspberry. All say they are RPi 3B+. Does it matter which one I purchase? Are they they same? I'm going to be using it for OctoPrint and not much else.

Thanks for any advice you care to share.

New to 3D, want RPi3B+ advice

by NaloMeliful

I currently use Ultimaker Cura (Beta) to print via USB on my new Anycubic i3 Mega. I’ve heard wondrous things about OctoPi and the RPi.

Am I correct in my understanding that the RPi is tethered via USB to the Printer but one can monitor from another device via the web or my home network?

If I purchase the RPI3B+ will I be able to download an STL and slice it on it? Or is the Pi strictly printer management?

Thanks for any enlightenment you can offer.

Peace, Nalo

RPI3 b+ with 3.5" screen

by Alter3go

i recently purchased a 3.5" screen for my RPI 3.
I followed instruction to install the drivers, which seemed to worked as can see all the booting up texts.
I then followed the instructions to boot to browser with TUI

After the reboot and load, the screen stopped on a blank/black screen. moving the stylus on the screen, I can see the Octoprint log in screen behind the block around the mouse cursor.

the same when I stop the TUI and the Pi loads to the desktop. When I move the mouse with the stylus, I can see the wallpaper appear around the mouse cursor.

I have been searching, but cannot find an explanation for this.

anyone have experienced this before?
