Build your own LEGO® MINDSTORMS® robot to solve the Rubik's Cube®...
MindCub3r is a robot that can be built from a single LEGO MINDSTORMS EV3 home set (31313) or from EV3 Education Core and Expansion sets (45544+45560) to solve the well known Rubik's Cube puzzle.
All MindCub3r software releases should work with LEGO EV3 firmware versions from v1.06H (home) and v1.06E (Education) onwards. It is recommended that the EV3 firmware is always updated to the latest version released from LEGO.
Construct the robot by carefully following the build instructions (Home) or build instructions (Education) and then download and install the software described below.
MindCub3r software consists of three main parts:
a project file: MindCub3r-v2p2.ev3 or MindCub3r-Ed-v2p2.ev3, containing the motor and sensor control program created using the standard LEGO MINDSTORMS EV3 graphical programming environment
an executable program: mc3solver-v2p2.rtf, compiled from C++ that implements an efficient solving algorithm that can find much shorter solutions than the NXT MindCuber variants
an EV3 application: "MC3 Solver v2p2", that is used to launch the mc3solver-v2p2.rtf program
Note: release v2p2 uses the .rtf extension to enable the files to be downloaded using the standard LEGO MINDSTORMS EV3 software. The .rtf extension is intended to be used for files containing text so using if for the executable program is a work-around. Please do not try to open this file with a text editor.
MindCub3r uses the EV3 color sensor in RGB mode to enable it to measure colors that cannot be distingished by the standard color mode provided by the standard LEGO MINDSTORMS EV3 software. The Color Sensor RGB Block must be imported into the LEGO MINDSTORMS EV3 software to support this mode.
NOTE: LEGO MINDSTORMS EV3 software for Mac OS from version 1.4.0 no longer supports importing blocks such as the ColorSensorRGB block. In this case there is an alternative method to download the MindCub3r software to the EV3 using a micro-SD card.Extract the file from this archive.

To change your Singtel WiFi password, you can typically use the My Singtel app or the router's web-based admin portal. Method 1: Using the My Singtel App This is the simplest method for most Singtel customers: My Singtel app on your mobile device. Log in using your credentials. Tap on the tab or the "More" icon (three horizontal lines). Manage WiFi WiFi Settings Select your router, then choose Change WiFi Name/Password Enter your new password and tap Method 2: Using the Router Admin Portal If you prefer using a web browser, follow these steps: Connect a computer or phone to your Singtel WiFi network.
: Look for tabs labeled "Wireless" , "Wi-Fi" , or "WLAN" .
Singtel’s patch is part of a broader industry shift. As home networks become more complex—integrating smart TVs, thermostats, and security cameras—ISPs are increasingly moving toward "managed home" ecosystems. The router is no longer just a pipe for the internet; it is a hub for value-added services.
Securing a Singtel network is no longer just about changing a password; it involves ensuring the underlying software is patched against modern threats. By utilizing the Singtel Support portal for credential management and allowing automatic firmware updates, users can maintain a high-security posture.
"It feels like I’m renting the router, not owning it," says Marcus Lim , a systems administrator and Singtel subscriber. "If I have a guest over who I don't want to share the password with, I can't just hop onto the browser and generate a new one. I have to call customer service or jump through hoops in an app. It’s my home network; why am I locked out of the cockpit?"
