Marlin 2.0 Firmware configured for Ender 3 + BL Touch

This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with the original or generic BL Touch sensors. The standard configuration file from Marlin distribution was carefully reviewed to include the latest Ender 3 specific settings from the official Creality firmware and from Antclabs.

Control Arduino via USB OTG from Android

This script allows Johnny-Five to run from a Termux terminal communicating with other Android apps or external devices by using the TCP protocol without root, without bluetooth and without the WiFi shield. The reason for the TCP protocol is that Termux still does not implement USB-OTG to Serial drivers and the vanilla Johnny-Five would hang right out the box because of this limitation.

V-Car app for rear WiFi camera

This is just a mirror to download the app V-Car, used in Chinese WiFi rearview and front cameras. I tested it myself and it does not require abusive permissions: access to WiFi configurations, microphone (to record sounds) and storage (to save videos). It worked well on Android 8.0 in my Galaxy S8.

Since I am not the developer of this software I will not answer any technical support question regarding this application. Download and use it at your own risk.

Prevent Chrome from signing in Google services

When you sign in Google Chrome with you credentials it will automatically sign you in all Google services (Drive, GMail, Keep, Calendar, Search, etc...). This can be useful but can also expose your personal data since there is no default way to protect Chrome with a password.

Google says in the help page the only way to do this is by using the Incognito Mode. That's not true. There is a way to keep your Chrome Browser signed in and at the same time be signed out of other Google services. This takes less than 30 seconds and does not require the installation of any app or plugin.
