Partsim online circuit simulator.

PartSim is a free and easy to use circuit simulator that runs in your web browser.
I create today my account to see how better is this online tool.
You can build, test and simulate your e with a SPICE Simulator, AC/DC/Transient Sims and Waveform Viewer.
The Arrow Integration lets the PartSim include an integrated Bill-Of-Materials manager that lets you assign Arrow Part Numbers to your models.

• Capacitor;
• Passive Low Pass Filter;

Firebase and Unity 3D.

Even is an old feature the Google team comes with this new option for the new developers and show how to use them.
The goal is to add Firebase to your Unity project.
The Google webpage tells us:
Power up your Unity games with our Firebase Unity SDKs. To show how easy it is to plug Firebase into your Unity project, we made a sample game, MechaHamster, that you can download from GitHub, the App Store, and the Google Play Store.
... and show a short video about how can be used to create a application named Mecha Hamster, see the GitHub webpage project:
You can import the project with GitHub commands:

https://github.com/google/mechahamster.git

The game is pretty funny, see the Youtube channel from Firebase:
