The project shows how a power supply from an old PC can be converted to deliver high currents in order to power electronics projects.
The 89S52 project board was designed for easy microcontroller development as it contains an In-System Programmable Flash based microcontroller.
This Superhet Receiver does not require AGC or RF control since it has satisfactory large signal handling capability as it operates with 4MHz intermediate frequency.
Producing a simple and cheap EPROM burner built on veroboard is the objective of this project which supports the 27c801.
A Microchip PIC16F628 is used as the controller chip for this low cost and simple Since/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip.
The need for an interaction designer to make cheap, quick, and dirty prototypes is the basis of building this 1-key keyboard as the easiest way to interface a single switch to a computer.
The project aims to emulate an old good Z80 machine on an AVR ATmega88 microcontroller to be able to run software that has to be CP/M machine emulated.
As an individual moves through the urban development, his experiences are sensed and that information is recorded for later reviewing by this personal space monitoring system known as Urban Sonar.
Two easily formed R/C pulse signals are converted into a PWM signal suitable for driving small motors as it uses an AVR chip and software.
This Twitwee Clock project is built from a wooden cuckoo clock and has the ability to connect to Internet wirelessly while constantly checking the status and updating on Twitter.
The project uses an Arduino to create a Twitter burglar alarm which can tweet in the event of an intruder entering the house without authorization.
The project captures cat door events and sends a Twitter message along with a picture to the Twitter in order to determine from which owner the other cats belong to since they are always seen in the garage feasting on the food.
The project illustrates how to build a homemade spot welder which can be used for welding two pieces of metal together by producing a highly defined point of contact weld and using a microwave oven transformer.
The quality of EEPROMs is tested in this project by allowing the Flash Destroyer device to write and verify an EEPROM memory until it reaches failure.
The project illustrates the setup and proper tools for back horn loudspeaker enclosure building which is pre-cut and pre-finished.
The project illustrates the implementation of Super Nintendo Entertainment System (SNES) game on FPGA where a 320x240 pixel VGA is used to output the image.
Simple hardware and software techniques are illustrated in this project wherein 3 common 4-coil stepper motors are driven and controlled using a single Stamp II board.
The purpose of the project is to spoof a simple low frequency 125kHz RFID tag with the use of an Arduino and only a few components.
