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

Game Boy Camera PC Serial Interface -  The results of their conversion are seen in Figure 2, which was obtained using the supplied evaluation software.  The supplied evaluation software can also be used to view FFT data (Figure 3) as well as a histogram for codes at a fixed dc level (Figure 4) __

Game Referee -  Here's another fun circuit.  This one is a referee for 'snap' or 'musical chairs' types of game.  In 'snap' mode the first player to press their button locks out everyone else whilst in 'musical chairs' mode the last player to press their button stays lit.   __ Designed by Richard Torrens

Game Show Indicator Lights (Who's First) -  This circuit turns on a light corresponding to the first of several buttons pressed in a "Who's First" game.  Three stages are shown but the circuit can be extended to include any number of buttons and lamps.  Three SCRs (silicon controlled rectifiers) are connected with a common cathode resistor (50 ohm) so that when any SCR conducts, the voltage on the cathodes will rise about 7 volts above the voltage at the junction of the 51K and 1K ohm resistors and prevent triggering of a second SCR.  When all lamps are off, and a button is pressed, the corresponding SCR is triggered due to __

Game Show Timers -  Here is a really simple game show timer designed with the beginner in mind! The power source is an ordinary 12 volt lantern battery or battery pack made up of C or D cells.  The lamps may be ordinary flashlight bulbs; the prototype uses 750 mA Krypton types (KPR112) with wires soldered directly onto the bulbs.  The control devices __ Contact: Charles Wenzel of Wenzel Associates, Inc.

GameCube Cop Keeps the Peace -  15-Jun-09 -Design News:   Three siblings and one GameCube is a recipe for territorial skirmishes.  Many games only support two users.  Jeremy Willden bought his three kids a GameCube for Christmas and quickly discovered parental intervention was critical.  He initially used a kitchen timer, but soon opted for a more technology __   Gadget Freak-Case #142

Gym Agility: a Simple Circuit Strategy Game using a 4067 multiplexer & 4093 Schmitt NAND gate -  This simple circuit is a two-person game of strategy and speedand potentially, agility and athletic fitness.  Each player has a row of four LEDs before him/her.  Beside each LED, there is a pushbutton which, when pressed, lights up the corresponding LED.  The aim of the game is for a player to illuminate all four of their LEDs in a row, in which case the circuit declares a winner.  However, there is a catch.  As soon as you light one of your own LEDs, the other player's corresponding LED goes outand vice versa.___ Learning Electronics

Interactive Beer Pong Table -  13-Apr-11 -Design News:   Since Cameron Hoerig is an engineering student at the University of Cincinnati, the idea of building a typical beer pong table was out of the question.  "I'm an electrical engineering student, so I should have a table that stands out," says Hoerig.  He built an interactive table.  On either end of the __   Gadget Freak-Case #184

Interactive, Arcade-Style Sandbox -  29-Sep-14 -Design News:   Cabe AtwellHuman-Machine Interfaces (HMIs) are a passion of mine.  I am forever looking for a better way to use the PC that's faster than the old keyboard and mouse.  Capacitive touch screens showed me much is possible.  Kinect, Leap Motion, and a few others tried, but failed to replace the standard.  Sega has __   Video-Gadget Freak

Interfacing Sony Control stick to Empeg -  After discovering that others had interfaced wired remote controls to their Empegs (including Sony control sticks) I decided to try to do it with the fewest components possible.  You may find that there are too few, if your power is very noisy (as can happen in a car environment) it may help to place a 0.1uF and/or 10uF capacitor before and/or after the voltage regulator.  At the moment I'm not using these but at this point I've only tested it on the bench, not in the car.  I'll update this web page after it's all installed. __ Designed by charlie @ armory.com

JAM(Just a Minute) Quiz Game -  This jam circuit can be used in quiz contests wherein any par- ticipant who presses his button (switch) before the other contestants, gets the first chance to answer a question.  The circuit given here permits up to eight contestants with each one allotted a distinct number (1 to 8).  The display will show the number of the contestant pressing his button before the others.  Simultaneously, a buzzer will also sound.   __

Jeopardy (Fastest Finger First) -  This project describes a "Fastest Finger First" system that is cheap to build, has high noise immunity, is reliable and is also extensible.  Note that whilst the schematic below may look complicated, its actually a very simple & cheap interlock based round a single 4013 dual d-type flip-flop and an output driver that is replicated for each positionin this example, 8 times.  The buzzer is also optional and can be omitted, along with all its associated components.  The few extra resistors & capacitors used for improving the noise immunity are very cheap but improve the reliability of the design greatly.  i.e.  it's a proper design rather than a hack! __ Designed by Nick de Smith

Joystick Interfaces -  This is a very simple circuit to interface a current loop sensor to an input which is designed for a voltage, such as that from a standard potentiometer.  This page is technical so that interested persons can build the circuit themselves, but 4QD can also supply the interface on a 'postage stamp' sized (22mm x 27mm) board as shown in the first diagram.  It is a relatively trivial circuit! __ Designed by Richard Torrens

Joystick Interfaces -  This is a page of analogue interfaces for joysticks.  Although these interfaces have been developed for use with 4QD's controllers they will have plenty of other uses.  Also because of the development history, we have printed circuit boards available (either fully populated and tested) or bare boards) for these interfaces. __ Designed by Richard Torrens

Judge Dredd pinball locking ring Modification -  Please read this entire document before installing anything.  You can buy this kit for $94 including priority mail shipping from Don Weingarden.  Supplies are limited, so email first to confirm availability.  The board is available separately for $45 plus $4 shipping.  The kit includes a new Dead World ring, matching the original but without the ball release slots __

Lazer Tag Equipment Modifications -  I added a "fast-fire" circuit to get around the annoying delay that prevents you from firing again immediately.  It used the target LED contact on the trigger switch to reset the pulse generator.  That way, normally when you fire the sound goes on for its normal duration (we banned any mod that would turn off the sound or always __ Designed by John DuBois

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

LED dice based on a 4060 chip -  Every self-respecting DIYer makes his own electronic dice with LEDs as spots.  Then you donít have to throw the dice anymore Ė just push the button.  The electronics also ensures that nobody can try to improve his luck by fiddling with the dice.  Too bad for sore losers! This circuit proves that an electronic die built using standard components can be made quite compact.  The key component of here is a type 4060 digital counter (IC1).___ Learning Electronics

LED Lighting Effects -  The original yoyo was equiped with 2 LEDs that lit up whendevice was spinning.  I decided to add a micro to give it some extra pazazz.  The trick here is to makeunit work without a power switch.  The mercury switch is positioned so that it supplies power whenunit is spinning.  After about 20 seconds, PIC shuts down in sleep modes,  __ Designed by Luhan Monat-Mesa Arizona

LED Zeppelin -  The name of our game, LED Zeppelin, is a play on words.  It comes not from the pop group of the same name but from Graf Von Zeppelin, a German who invented the first rigid air ship in 1900.  The association fits perfectly.  The game consists of six LEDs and an indicator LED that flashes at a rate of about 2 cycles per second.  A push button is the "Operations Control" and by carefully pushing the button in synchronisation with the flashing LED, the row of LEDs will gradually light up __ Contact: Collin Mitchell

LEDs or Lamps Sequencer -  Very simple, versatile modular design No limits to the number of modules used in the ring __ Contact: Flavio Dellepiane, fladello @ tin.it

Lego Mindstoms IR Link PIC transceiver -  I just finished a half duplex serial asynchronous link from a simple PIC circuit to the RCX.  It is able to receive codes from the RCX (or Lego RCX remote control) store them in RAM & EEPROM and transmit any IR op-code to the RCX in turn.  Included in the firmware is a routine that takes any opcode(s) and expand it to the proper IR packet for transmission to the RCX.  I've used the UIRT circuit with a few modifications for the hardware.  The UIRT includes a serial port programmer for the PIC16F84A so you won't need a separate programmer.  Here's the website where you can find the programmer.  Here are the modifications to get the UIRT to work with the RCX.   __ Designed by Lloyd Gordon

Lego Mindstorms Double Rotation Sensor -  I usually use one motor for the left wheel and one for the right wheel.  The problem is that the motors are never perfectly matched and my RCX ends up going in circles.  I thought of buying two rotation sensors to keep track of the rotation of both wheel axles.  However this would use up two sensor ports, leaving only one for my other sensors __ Designed by Lloyd Gordon
