Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
[GlobalSpec-AD/ad-smSQ-ihsGS.htm]

The A-1 Robot - This Robot is created using a Radio Shack project box. I have used many of the circuits from DiscoverCircuits. com with my ideas for AI-A-1. .

 

The Agilent 34980A A Low Cost Alternative to VXI & PXI - Application Note. . . [Agilent]

 

The Behavior of CMOS in Hot Insertion - Application Brief # 039. . . [Pericom Semiconductor]

 

The COP444l Evaluation - Application Note. . . [National Semiconductor]

 

The Dashboard Digital Voltmeter Project - This project is helpful to anyone who drives an automobile. I had found this project at the local library. in an old publication. I made it and it worked fine. Below are the complete text and schematic of the Dashboard Digital Voltmeter. I re-typed the text and re-drew the schematic. as the printing from the book was old and faded. Sit back and read the story why this LED display might just save you from being stranded on the road!. . . [braincambre500 AT yahoo.com]

The HC11 Controls the Stepper - . . . [Ludwig Orgler-Fachingenieur Elektrotechnik]

[Google-ADS/i-ad-EVEN-2SQ-GGL.htm]

The New Micro-DAC Product Line for Microprocessor Systems - Application Note. . . [National Semiconductor]

 

The Quest for a New Generation Analyzer - Application Note. . . [Agilent]

 

The Silicon Wallet - Forgot your password? To design my tiny password reminder, I devised an input circuit that enables any embedded device to capture information from a web browser. Cypress PSoC based digital wallet; to record secret codes and passwords securely. . . [by Alberto Rico Bitti]

 

Theory & Application of the ML4821 Average Current Mode PFC Controller/AN-42030 - Fairchild App Note - . . .

 

Thermoelectric Controller scriptable Thermometer - A unified thermometric controller that can be programmed with simple scripts, integrating the "classic" thermometer/controller pair. You can build a variety of simple machines with the same hardware and a different script : a charting thermometer, a vending machine that dials your number when empty, a leavening cell. . . [Alberto Ricci Bitto]

 

Third Generation Power Conversion Solution for Pentium II Motherboards/AN-57 - Fairchild App Note - . . .

 

Throughput Expansion with FET Based Crossbar Switching - Application Note # 045. . . [Pericom Semiconductor]

 

Time Keeping using a COP800 MicroController - Application Note. . . [National Semiconductor]

 

Timer has independent on/off period - 03/28/96 EDN Design Idea   You can easily implement a long-interval digital timer using the popular 4060 oscillator-divider IC. However, in repetitive-timer applications, this IC produces equal on and off times. The circuit in Figure 1 allows you to set di. . . [by Sanjay R Chendvankar, Tata Institute of Fundamental Research, Bombay, India]

 

Time-tag impulses with zero-crossing circuit - 01/24/02  EDN Design Idea   A "constant-fraction discriminator" usually performs the time-tagging of impulsive events, which have a peaking time of the signal Amplitude. The implementation of this technique requires a delay in the input signal of approximately. . . [by Elio Rossi, Itesre-CNR, Bologna, Italy]

 

Tiny 2313 Project Development Board - This is my first time using the AVR. I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple. The chip has only 20 pins. I was interested because I want to build a simple line follower robot controlled by this MCU. . . [Tahan Prahara, designer]

 

TMC22x5y Input Data Ranges/AN-60 - Fairchild App Note - . . .

 

Total Dose Testing of Advanced CMOS Logic at Low Voltage - Application Note. . . [National Semiconductor]

 

Total Power Conversion Solution for Pentium II Motherboards/AN-56 - Fairchild App Note - . . .

 

Touch Keypad - This board layout was created using the SOIC version of a PIC16F627A without drawing the usual schematic first. Most of the part values are etched on the Layout. The SIP resistor packs I used are 10k ohm, some experimentation with this value may be useful. . . [Luhan Monat - Mesa Arizona]

 

Touch Switch - PIC Project  . . . [Luhan Monat - Mesa Arizona]

 

Toward More-Compact Digital Microphones - Analog Devices-Analog Dialogue. . . [by Furst, Claus and Nielsen, Jannik]

 

Toy Car Rodent - This car measures just 5 1/2 inches in length. It was sold as a remote control car for $19. 95 at Fry's Electronics here in Phoenix. Powered by 4 AAA batteries, it has a small dc motor and a very interesting steering mechanism. (08/08/08) . . . [Luhan Monat - Mesa Arizona]
