Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
Effects of Digital Crosstalk in Data Converters -  Maxim Application Notes / 1761 / May-06.....[App Note]
Effects Of Parasitics In Circuit Simulations 12/11/00  -  Application Note California Eastern Laboratories Doc #930.....[App Note]
Efficient Processor Power System Needs No Heat Sink -  DN135  Design Notes (Linear Technology) (app note added 1/06)
Efficient Use of PCI: Intel discusses basic concepts of PCI Performance -  Agilent Application Note.....[App Note]
Electronic lock -  Schematic only, no circuit description
Electronic Lock -  This is my electronic combination lock to use with an outdoor gate. The functionality is implemented in software. It turns on a relay (usually to open a door) for a few seconds…. Uses a PIC16F84A…. [Peter Jakab, Electrical Engineer, Engineer of Informatics]
Electronic Lock (Bill Bowden) -  The digital lock shown below uses 4 common logic ICs to allow controlling a relay by entering a 4 digit number on a keypad. The first 4 outputs from the CD4017 decade counter (pins 3,2,4,7) are gated.....(added 05/07)

Electronic Locker -  This circuit is an Electronic Locker. It is controlled by a switches combination (by a code). There is a switch matrix on the door of the locker.  This one is a unit of switches connected into 4 arranged of 4 columns for a total of eight terminals.....(Circuit design added 09/08) [Site is under construction right now]
Electronically generate rotating magnetic fields -  18-Feb-10 Issue of EDN  Generate magnetic fields with a microcontroller instead of mechanical parts..... [Design Idea by F Ferrero, J Blanco, JC Campo, and M Valledor, University of Oviedo, Gijón, Spain]
Embedded Assembly Routines into C Language using a Floating Point Routine as an Example -  Microchip Application Note Published 26-Aug-97  (app note added 2/06)
Embedded Memory Enhances Programmable Logic for Complex Designs -  11/07/96 EDN-Design Feature  The growing densities of PLDs are making the chips suitable for increasingly complex designs. Those designs require high-performance scratchpad RAM for temporary storage of data that passes through the logic circuitry that the chips implement. Vendors are responding with new devices..... [Design Feature by Rick Nelson, Contributing EDFtor]
Embedding Picmicro MicroControllers in the Internet -  Microchip Application Note Published 26-Jun-00  (app note added 2/06)
Engine/Race Computer Board -  The objective of this project is to design a high speed digital engine tachometer.  This requires the design and development of a hardware and software solution to monitor the status of an engine in real time. In addition, information relating to the overall health and systems of the vehicle can be displayed.  (added 10/05)
Enhanced 4-Digit Alarm Control Keypad -  This Keypad is suitable for the Modular Burglar Alarm. However, it has other applications. Pressing a single key will energize the relay. Entering the Four-Digit code of your choice will de-energize it….(Circuit design added 08/08/08)
EPROM adapter for ATMEL 89 Programmer -  ….(electronic schematic added 08/08)
EPROM Programmer Mk2 -  This design was never completely finished, so consider it to be in the very early experimental stage. I don't sell kits, programmed PLD's, or provide support for this project, and I will never be published. But if you want to take a bash at making it yourself, be my guest, it may or may not work, I guarantee nothing. Try it at your own risk. PLEASE don't contact me about this(added 11/05)
Evaluation Kit for the 32-Position, Push Button, Up/Down Control Digital Potentiometer -  AN-712 Analog Devices Application Notes.....[App Note]
Evaluation Kit for the AD5253 64-Position I2C-Compatible Nonvolatile Memory Digital Potentiometer -  AN-728 Analog Devices Application Notes.....[App Note]
