‘Space Invaders ‘ Hand Video Game -  A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video monitor.  Electronic video games first appeared in the 1950s....___ Electronics Projects for You

2-wire Game Show Time -  Several Game Show timers included, scroll to find this one.  The game show timer determines which contestant presses their button first by lighting a lamp and ringing a bell and the slower  contestants are locked out.    __ Contact: Charles Wenzel of Wenzel Associates, Inc.

36 LED Chaser -  example of multiplexed display to produce a chaserled's were mounted in a circle __ Contact: P. Townshend EduTek Ltd

3-up Decision maker -  This electronic device will help you make important decisions   (or not).  While it is deciding the solution to your problem it will convince you how difficult it really is by a painful growling noiseor maybe this is normal when you have to think!___ CdS Electronic

3V LED Chaser -  There are many 9V chaser circuits that seem to waste about 7V when driving LEDs that are only about 2V.  This project is unique, because it uses only two inexpensive alkaline battery cells totaling 3V for power.  Since most of the waste is eliminated, the cells last a long time.  Unlike the other circuits, this one flashes the LEDs for only about 30ms each, further extending the battery life.  For user convenience, it has a stepper speed control and a brightness control.  At slower speeds and with reduced brightness,  __ Contact: IQ Technologies

4 Way Spinner -  A 4 light bulb spinner that slows and stops on a random bulb.  PCB included in pdf __ Contact: P. Townshend EduTek Ltd

555 timer LED dice -  This project has two advantages over previous dice circuits.  It produces a realistic readout as well as a 'slow-down' feature.  These combine to make it one of our most popular games projects.  As can been seen in the photo, the 7 LEDs are positioned on the board in the same positions as the spots on a dice (die).  When these are activated, they simulate the rolling of a real dice as it rolls across the table.   __ Contact: Collin Mitchell

6V ultra-bright LED chaser using 74HC4017 -  This is a spectacular but completely useless project.  It lights Ultra-Bright LEDs in a sequence and each LED flashes brightly very briefly.  The LEDs light-up going around and around since they are mounted in a circle   (on a CD) , then they pause __ Designed by Audioguru

A CharliePlexed RGB LED Dice -  The project uses 7 RGB LEDs arranged in the form of dice.  Each RGB LED has three separate LEDs inside so that makes a total of 21 LEDs and they have been controlled by 4 I/O pins of ATTiny13V Microcontroller.  But according to the theory of __

A PC Games Port Tester -  So your joystick dosen't work? Is it the games port, a software problem or the joystick itself? This simple device will tell you if the games port is OK.___ SiliconChip

Adapter to use Mega Drive / Genesis Controllers with a Vectrex Video Game Console -  The Vectrex itself uses a very simple controller circuit, which can bee seen in this schematic from the Vectrex service manual __ Designed by Kevin Koster

Adding Second Joystick to PC Joystick Interface -  PC joystick interface was designed to support two joysticks, but unfortunately it has only one connector.  The second joystick can be added when you get a special Y-cable, which has connectors for two joysticks.  Those cables can be bought ready-made.   __ Designed by Tomi Engdahl

Another Game Show Timer -  Several Game Show timers included, scroll to find this one.  Here is a somewhat more complex version that uses easily found bipolar transistors.  Note that it requires only two wires between stations and base and those wires can be connected anywhere on the "buss".    (You can wire each station back to the base unit or "daisy chain" the stations from one to the next with only one set of wires going back to the base unit.) __ Contact: Charles Wenzel of Wenzel Associates, Inc.

Archery Timer -  In FITA-style archery tournaments there are rules to the timing of the event.  From the 2000 FITA rulebook here are the rules that the timer must serve __ Designed by A. Ron Carmichael

Atari Punk Console Schematics -  The so called “Atari Punk Console” device is a great start for builders interested in working with components and circuitry to produce Bleepy-Bloopy-Gitchy goodness.  Using a 556 dual timer IC and a handful of other components one can be built quickly.  The basis for this noise maker was a schematic originally published by Forest Mims III, which now can be found around the web and posted above for easy reference.   __

Ball Speed Checker -  This circuit measures the speed of a cricket ball based on the time taken by the ball to travel the distance from the bowling crease to the batting crease.  As shown in...___ Electronics Projects for You

Battery Meter for Pinball Machines -  Well here it is as promiseda battery tester for giving visual indication of the battery pack in your pinball machine.  Luckily I had a spare day forced on me by car trouble so I've managed to design and test the circuitry earlier than planned   (fixed the car too!) and I've still got time to write this article, and maybe, down a bottle of my favourite wine! __ Designed by David Gersic

Birthday Heart -  This circuit was made for my wife's birthday.  It is capable of flashing five strings of LED's with different frequencies.  It also has a connector for an 8 Ohm loudspeaker and two connectors for the small PCB's that are contained in musical greeting cards.  In this way the circuit will play alternatingly two room filling tunes at regular time intervals.  After a w __ Designed by Michel Van den Bergh On Electronics

Build a LED Dice -  A PIC microcontroller makes the circuit really simple.  We tell you how it was designed and show you how to build it.___ SiliconChip

Build your own Joysticks & Controllers -  Building your own normal PC joystick is not economically wise, but if you can't find a joystick you would like to have, then you have te consider doing it yourself.  The connections inside PC joystick are quite simple to do, the harder part is the mechanics.  Buttons are quite easy to mout to the case you use when you select suitable buttons, but the problematic __ Designed by Tomi Engdahl

Build Your Own Marshmallow Cannon -  Marshmallows, not just for rice crispy treats anymore. __ Contact: Jameco Electronics

Burger Time Arcade Game -  This is a ZIP file __ Contact: jrokweb @ san.rr.com

Cat Toy with a Small Weighted Motor -  The PIC12F675 is small in size and low in power.  It lends itself to some really off-beat uses __ Designed by Luhan MonatMesa Arizona

Christmas Star -  This project started just before last Christmas when my daughters asked "why don’t we have any flashing Christmas tree lights?" So, while they were out shopping, my son and I grabbed a dozen LEDs, some ribbon cable and a microcontroller.  While my son wired up the LEDs, I wrote some simple software.  It was all installed and running when they came home after spending all my money (that’s why we didn’t have lights before) ! The smiles on their faces made it all worth while! __ Designed by © Grantronics Pty Ltd

Circuit improves further on first-event Detector -  06/27/02 EDN-Design Ideas The circuits in Figure 1have certain advantages over those in a previous Design Idea(Reference 1].  The first-event detector with autoreset(Figure 1a] consists of N sets of monostable multivibrators, using 4001 logic circuits with LEDs attached.  After any player(1 through N] presses a pushbutton, the corresponding monostable multivibrator switches on, and its associated LED lights__ Circuit Design by Vasiliy Borodai, Zaporozhje, Ukraine

Circuit improves on first-event Detection -  08/16/01 EDN-Design Ideas The circuits in Figure 1 and Figure 2 exhibit certain advantages over the circuit shown in the Design Ideas in EDN, "Circuit detects first event," May 3, 2001, pg 89.  The n-player first-event-detection circuit offers several improvements  It has fewer passive components.  It needs only n diodes instead of(n2+n]/2 for three orplayers__ Circuit Design by Lawrence Arendt, Oak Bluff, MN, Canada

Coin Tosser -  Build your own coin toss circuit and lose the coin. __ Contact: Jim Stewart, Nuts and Volts Magazine

Coin Tosser -  The UJT transistor Q1 can be replaced with a NTE6409 or ECG6409.  At the press of S1 the oscillator starts and runs the clock on pin 14 of the CD4017 decade counter at a time determined by R1 and C1.  During that time both LED's will flash back and forth until the oscillator stops and either the red or green led will be lit.  The values shown are for working with 9 volts and none of the parts are critical. __ Contact: Tony van Roon  VA3AVR

Combinational Conjuring Trick -  The simple circuit of Fig.1 emulates a similar conjuring trick which sells for hundreds of Pounds.  The trick seems to do the almost-impossible from an electronic point of view, let alone from the point of view of common sense.  It consists of a bank of three on-off switches (S19-S21) , which have three switch covers, each of a different colour.  These switch a bank of three lightbulbs __ Designed by Andy Collison

Conjuring Trick-Magic Wand -  This simple conjuring trick is intended to provide some enjoyment for the beginner in electronics or conjuring, and should take only an hour or two to build.  The trick works as follows: a wand __ Designed by Andy Collison

Connect Others to PC Joystick Port -  PC joystick port can be a very useful interface for simple digital input circuits, because joystick connector has +5V power output, which other standard PC interface connectors don't have.  You need to be a little bit careful with this power output, because it can give quite much current in short circuit situation (up to 20A in some cases).  This current is enough for burning small wires in your circuit or inside your PC (I have burned one flatcable coming form multi-IO card to joytick connector !) __ Designed by Tomi Engdahl

Connecting Sega 3d Glasses to a PC Serial Port -  This documents ties to clear out one method for connecting Sega 3D glasses to PC serial port for cheap PC virtual reality.  This who do no not know what those Sega 3D glasses are, here is a description: __ Designed by Tomi Engdahl

Co-Ordinator -  A games of skill & patience.  This project combines some of the components and building blocks we have covered in the courses in this e-magazine.  It's a game of skill that tests your reaction-time and patience.  Patience, because a certain condition appears on the indicator LEDs, only every few seconds and it corresponds to them both being OFF.   __ Contact: Collin Mitchell

Cuckoo-song Generator -  This circuit generates a two-tone effect very much alike the cuckoo song.  It can be used for door-bells or other purposes thanks to a built-in audio amplifier and loudspeaker
Used as a sound effect generator it can be connected to external amplifiers, tape recorders etc.  In this case, the built-in audio amplifier and loudspeaker may be omitted and the output taken across C8 and ground.   __ Contact: Flavio Dellepiane, fladello @ tin.it

Decision maker -  No circuit description, schematic only___ CdS Electronic

Dice with 7-Segment Display -  A digital dice circuit can be easily realised using an astable oscillator circuit followed by a counter, display driver and a display.  Here we have used a timer NE555 as an astable...___ Electronics Projects for You

Digital Game Show Timer -  Several Game Show timers included, scroll to find this one.  Using only two CMOS IC packages, this game show buzzer performs well enough to be on TV! The first contestant to press his button locks out the other two contestants.  The design is completely asynchronous and "fair".  Other logic families will also work and any appropriate power supply is fine.  For simplicity, a single-chime doorbell is used for the aural indicator.  If a buzzer is preferred, use double pole pushbuttons with the second poles connected to activate the buzzer.  Simply connecting a buzzer in place of the doorbell will work but the buzzer will sound until the reset switch is pushed.   __ Contact: Charles Wenzel of Wenzel Associates, Inc.
