| About: Welcome to the hardware page. The E-Series is a collection of processor-driven projects which range from simple light flashers to home security devices. Most of these were developed for AVR microcontrollers, however other platforms may appear in the future. Click on any picture below to view the project. | ||
| AVR Tutorial | status: complete | Code Lock Demo | status: complete |
Project E-3
|
This AVR tutorial introduces the ATMEL STK500 developer board and some of this basics behind starting a first-time AVR project with emphasis on both hardware and software. In addition to the source code on this page, the instructions are described on a line-by-line basis. |
Project E-5
|
Another tutorial involving the use of EEPROM and SRAM to hold access control codes. The circuit can be used to activate an external relay after a correct key pattern is entered. It also demonstrates how a string of keystrokes may be read from a 74C922 Keypad Interpreter chip. |

| Card Reader | status: complete | TI Expander | status: complete |
Project E-13
|
A debugging tool that can scan and store data from various magstripe card types. This includes Drivers Licenses, credit cards, phone cards, and even gift cards. The AVR can scan and print this data to a character LCD display using the code featured here |
Project E-16
|
A power supply augmentation for all Texas Instruments graphing calculators. The current attachment increases energy capacity by 200% and enables it to run off several types of wall adapters. Thanks to voltage regulation, it also tends to lower processing time. |

| IR Receiver | status: complete | IR Transmitter | status: complete |
Project E-19
|
This system uses the AVR controller to create a very simple infrared receiver. When used with the infrared transmitter, you can use the pair to transfer wireless data to 10 meters. This receiver can also read commands from television remotes using the popular RC5 protocol. |
Project E-20
|
Use an AVR controller to transmit infrared data to your next project. This transmitter version can accept keystrokes from a small keypad or other data source. The system uses the popular RC5 protocol and the software-generated IR signals keep external hardware at a minimum. |

| SNES Interpreter | status: complete | PSX Interpreter | status: complete |
Project E-21
|
A "just-for-fun" project for remote control equipment. The SNES gamepad has truely earned its keep when it comes to user finterfacing. The SNES gamepad pinout and protocol are presented in detail. |
Project E-22
|
Uses an AVR to decode the highly-robust and highly-versatile Playstation controller. With only a little imagination, it is possible to adapt the keypad for most any radio-control project! The Playstation gamepad pinout and protocol are presented in detail. |

| UV Circuit Etcher | status: construction phase | Shock Sensor | status: under revision |
Project E-17
|
The Etchlab is an automated platform that will expose, develop, and etch circuitboards for future projects. The project will span subjects requiring electrical, software, chemical, mechanical, and thermal design. |
Project E-24
|
This project creates a shock and tilt-sensitive alarm system to guard anything from bookbags to windows and doors. Thanks to the previous IR reciever project that preceeded it, the SafeGuard can even be controlled remotely. |
