Linux /dev/input/event* Thanks for Anton’s Mindstorms Hacks, evdev and Linux Input drivers v1.0 (c) 1999-2001 Vojtech Pavlik, they gave us good idea … Continue reading LEGO MindStorms – Znap with PS4 controller →

My dad told us that he wanted a RC car with a professional controller like this… that’s one of his childhood dream. He was so excited with such professional controller we made…. HOWEVER, we built him this ‘car’… LOL This is a great project to make use of … Continue reading LEGO MindStorms – Znap with a remote controller →

For this project, we have decided to build a Rubik cube solver. This Rubik cube solver was not easy to build, we came over lots of obstacle in the way, such as motor jammed, sensor too weak to detect cube and some building mistakes. It was hard work … Continue reading LEGO MindStorms – Rubik Solver MindCub3r →

When we built the factory, we thought that the EV3 Home (Scratch base) can support two bricks. However, no ever how much information we read, it is not what we expected. We were trying to modify factory by adding additional color sensor, so that we can use two … Continue reading LEGO MindStorms – Spinner Factory →

This project is so funny and cool, we are controlling a robot which contain the cart and the lifting arm, so that it can climb stairs. Looks like a Mars rover!! Features of the robot Gyro Sensor – It is used to detect or reference the degrees that … Continue reading LEGO MindStorms – Stair Climber →

Calibration The best part for this elephant is installed two sensors to detect the trunk and the head movement, so that we can program this to avoid the motor over-driving the head and trunk to induce unnecessary damaged. Calibration is very important for machine and robot, identify the … Continue reading LEGO MindStorms – Elephant →

We tried the water level sensor today and using a RGB to indicate different water level, let us show you how to do this. How does water level sensor work When we use the water level sensor, we need to connect to 5V, GND and Signal to the … Continue reading Water Level Sensor →

This is our second Arduino project, using 4 piece 7-segment LED display to create a DEC / HEX counter which can support both common anode and common cathode components. 7 Segment Display See the photo for how we connect the 7 segment display, you need to connect a … Continue reading 7 Segment DEC & HEX counter →

When you deal with diode or transistor components such as LED, 7 Segment display, RGB LED, etc., you need to understand whether the component is common anode or common cathode, it will give you completely different result. 7 Segment Display Let’s us the 7 Segment display as example. … Continue reading Anode vs Cathode →

R – Red, G – Green, B – Blue, basic display component to display color. We call this as one pixel for all display unit, such as monitor, TV and smart phone. It contains three inputs for red, green and blue, as well as a common ground(1). When … Continue reading RGB LED →

After we learnt some basic idea about the Arduino UNO board and basic LED circuitry, we started to build our first project – LED array. But, keep in mind, always put loading (i.e. resistor) for LED. Otherwise, you will burn it or even damaged the board. We built … Continue reading Our First PCBA →

Potato is so brave to fight with a ‘snake’…..
