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.
