iPhone Loudspeaker Amplifier
Posted May 23, 2013 By Mark HarringtonThe circuit idea came from two sources a young lad round the corner from me who I chanced on a week ago Its a joint effort with something that he showed me. So after chatting to him I said Id put together an amplifier for him so that he might continue his interest in electronics / project making… So here it is. I’m really hoping that this can be teamed up with another person who… -
Your own home made Raspberry pi power supply from Scrap
Posted Mar 14, 2013 By Mark HarringtonWhat prompted me to do this was the fact that the raspberry pi is known to draw more than 800 ma close to an amp when its fully operational and used at its maximum capability I know full well how bad mobile phone supplies are nevermind the ordinary run of the mil supplies you buy in shop The regulation is so poor you might as well open it up and have a good look inside then you will… -
Cell Phone Detector
Posted Mar 09, 2013 By Circuit ProjectsThe circuit schematic is given in the .rar archive attachment. There are two separate detector units. Every detector unit consists of a dipole antenna, a choke and a diode. The antenna receives the GSM signals in media. Then a small amount of charge is induced in the choke. The diode demodulates the signal and finishes detecting. The diodes must be schottky diodes or germanium diodes. Since the… -
PIC and EEPROM Programmer
Posted Mar 01, 2013 By Circuit ProjectsThe programmer also provides ICSP feature that allows In-Circuit Serial Programming. So if you desire, you will not have to carry your MCU each time when you reprogram it. The circuit is connected to the PC via serial port and no external power supply is needed. On the other hand, if you want to use it with a laptop that do not provide RS232 connection, using the circuit with a USB to… -
300 Watt MOSFET Real HI-FI Power Amplifier
Posted Feb 28, 2013 By Circuit ProjectsI am committed to sharing my experience of the RAS 300 with other enthusiasts sharing my passion for perfection.I designed this minimalist amplifier to be durable, simple to operate while offering high fidelity equivalent to the original sound source and would recommend partnering this amplifier only with other products of outstanding quality. When I set out to design this amplifier,… -
FPGA Ray Tracer
Posted Feb 14, 2013 By Yunfan ZhangIntroduction Our final project in ECE576 was implementing a ray tracer capable of rendering, rotating, and moving spheres. Our initial goal was to realistically render and shade spheres with reflections while being able to navigate through the scene and allow the spheres to bounce and roll around. Once we met this goal, we added anti-aliasing and the ability to render planes as well…. -
Cortex-M3 MCU STM32-based LCD controller
Posted Jan 28, 2013 By Tian ChuThis is an embedded system application project finished during my intern at ST Microelectronics (Shanghai) Co.,Ltd. This project provided me a precious hands-on opportunity to independently work on an embedded system application, and developed my skills in schematic design, PCB layout and C programming. -
Efficient Yield Estimation and Optimization for a 6-T SRAM Cell
Posted Jan 15, 2013 By Kalpana Manickavasagam1. INTRODUCTION Memories constitute a huge portion of the revenues to the semiconductor industry. Specifically, the SRAM cache, occupying more than 50% of the area, consumes a major fraction of the total power. It also dictates the critical path delay of the circuit. With technology scaling combined with random dopant fluctuations, the variations in the threshold voltages and effective…
