Simulation of Plot Clock for Optimization

This is a small program I wrote for simulating Plot Clock,which is a really hilarious small clock with two robotic scissor arm that keep plotting time on a panel.If you’ve never watched how it moved before,check this out.

Rotary Inverted Pendulum

This is a project I built with my teammates in an Electronics Design Contest in 2013.That contest was a electronics marathon as we were required to choose one of the given tasks and finished it in 4 days.No provided materials,no help from others so we had to built it from scratch.It’s definitely not perfect but we successfully finished all the requirement :) !

Simulation of BLDC Motor Speed PI Control in Simulink

This is the final project of my course Adjustable Speed Motor Drive.Thanks to Prof. Bilal Akin I’ve so much valuable knowledge about motor drive.

This post is a summary of my project report.

Building A Self Balancing Race Car

This post is to introduce the self-balancing smart car I built in 2013.My teammate and I spent several months to build a self-balancing car from a RC car chassis,and we also made most of the hardware modules and coded overnight just want to make it run faster and faster before the contest.Still remember the day when we competed with hundreds of teams from other universities :)

Mini Stereo Digital Audio Processor (MSDAP)

This is a course project of ASIC.MSDAP is a low-cost, low-power and application specific mini stereo digital audio processor used in a hearing aid.The main function of this processor is a two-channel, 256 order, finite impulse response (FIR) digital filter.It receives 16 bits voice data(sampled at 48 kHz) and computes the FIR result at the speed of 26.88MHz.This is still an ongoing project,which is supposed to be finished in Dec 2015.Right now it’s designed in behavioral level later on it will be designed in RTL level.I’ll update this post and put all my works here here but before that I can only show part of this project,otherwise I’ll be mistaken for copying someone else’s code :P

Prototyping An Entrance Guard System

This is a project I’ve in 2014 and later on it was posted right here 门禁系统的设计与实现-2014.12.6更新(in Chinese).

In this project I tried to build an Entrance Guard System using Atmega328.Here’s the main features:

• LCD screen and keyboard for interacting
• Voice communication(telephone quality)
• Relay circuit for controlling 12v magnetic door lock
• Password login
