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] |

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] |

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 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
