My work

This page shows hardware related blog entries organized by the projects they are about.

Big Red Button

This is basically a USB keyboard put into a box with one of its keys replaced with a big red button. The function of the button can be changed via two hidden switches at the bottom. The 4 possible states of the switches can set the big red button to either Space, Pause, Scroll Lock or F11.

LED strip controller

It can drive an RGB LED strip which can be up to 25 meters long, using music as input. This can come from any device with a line level output (basically all PCs, mobile phones or Hi-Fi systems). It uses a visual equalizer which separates the audio into 3 channels: low, middle and high frequency, and each of these correspond to a specific color. The device also supports passive modes, where no input is needed.

Digital Car Voltage Meter

The device is able to display the car's battery voltage level, even when the engine is running. No need for opening the hood, it only needs to be pugged into the cigarette lighter.

Graph-based Simultaneous Localization and Mapping

This is my graduation project which I worked on with my partner. The goal was to create a software which can map its surrounding into virtual space using a Microsoft Kinect sensor, and then use this map to search for a path where a robot can safely navigate.

Work in progress

Star Trek working combadge

The goal is to recreate a working combadge from Star Trek which chirps when the wearer touches is, just like in the movies. The badge is the one used in the series Deep Space 9 and Voyager.

PID controller project

The goal is to design a PID controller using a micro controller, which controls a contraption made out of Lego.
