This simple audio spectrum analyzer is based on PIC32 proto board on PIC32MX360F512L with 320×240px colour LCD (LVC75Z779 Eval Board). The analyzer can be connected to unamplified audio source like PC’s sound card, MP3 player and so on. SSD1928 Module Schematic diagram The reference voltage of ADC is set to 1V with potentiometer connected to […]

Usbpicprog is an USB in circuit programmer for Microchip PIC processors family PIC10F, PIC12F, PIC16F, PIC18F, PIC24F, PIC32F and I2C Eeprom 24xx. The hardware is as simple as possible, the current version only contains one PIC18F2550, 4 mosfets, and besides the connectors a hand full of passive components. Components Usbpicprog consists of three main components: […]
System Overview La Fontaine Du Campus Est (The Fountain of East Campus) is a computer-controlled, servo-actuated, LED and halogen-lit, sump-pump powered water fountain. It features five streams of water that can each be individually controlled (on/off) as well as pivoted (90 degrees of freedom). Each stream of water is lit by a halogen light. The […]
We have been wanting to design and build an open-design, relatively inexpensive but fully functioned charge regulator for solar PV, wind, pedal and small hydro systems for a while now. The majority of off-grid renewable energy systems are based upon lead acid batteries. Lead-acid batteries need to be protected from over-charging by the renewable energy […]
The project demonstrates the implementation of the sound spectrum analyzer for 8-bit microcontroller PIC18F4550 manufactured by Microchip . Spectrum analysis is performed using an optimized fast Fourier transform algorithm (Fast Fourier Transformation, FFT), written entirely in C language. Data Visualization (spectrum) is carried out in real time on a graphical LCD display with a resolution […]
Introduction When I first started in the field of robotics, electronics and sensors I had always wanted to make my own robotic arm. The idea of being able to make such an advanced idea come to life out of simple parts found around the house was mind boggling to me. So inspite of that, I […]
Introduction For our final project we built a dynamometer that measures various performance characteristics of small electric motors, such as torque, rpm and efficiency. The final goal was to be able to produce a motor efficiency map like this one, but for this class project the goal was just to get everything designed and functioning: […]
UPDATE 11/7/12 – More pics of device and full disassembly uploaded by Ad. Thanks!. A user nicknamed “Ad” has taken some pictures of the inside of a new induction cooktop by Better China, see their original comments at this article. This device is interesting because it appears to be a streamlined version of the Burton […]
Introduction When sailing a boat, one of the most important factors is the direction of the wind. If they want to keep a steady heading, sailors need to be able to dynamically adjust the direction they steer as the wind changes. Unfortunately, the ability to tell exactly which direction the wind is blowing can be […]
