INTRODUCTIONElectronic Roulette (roo-let) replaces the ivory ballwith a circuit of flashing light emitting diodes (LEDs).Red LEDs are arranged in a circle next to a black orred number and two green LEDs are positioned nextto “0” and “00”. When the switch is pushed, the LEDslight one after another, in a sequence that representsthe movement of the ivory ball. The number next to

the lit LED when movement stops is the winningnumber. During movement, the sound of a bouncingball is generated. If the switch is not pressed again,the circuits will automatically turn off, to conserve thebattery power. A constant tone will alert you to checkyour number before automatic shut down.

THEORY OF OPERATION

THE BLOCK DIAGRAMThe function of many of the circuits will be presentedin the form of an analogy (similar operation, buteasier-to-understand system). In this manner, theoperation of a circuit can be explained without theuse of mathematics and equations.Figure 1 shows a Block Diagram of the ElectronicRoulette circuits. The Timer circuit is used to turn allthe other circuits on and off. The Pulse Generatormakes pulses that create the sound and force thering counter to move the position of the lit LED. TheSound Circuit generates the sound of a bouncingivory ball, and a warning tone a few seconds beforepower down. The Ring Counter lights each LED in acircular sequence. The LEDs represent the positionof the ivory ball.

THE TIMERWhen S1, the start button, is pushed, capacitor C7(Figure 2, Schematic Diagram) is charged to thebattery voltage. This is similar to flipping the “TimerGlass” shown in Figure 2a to produce the conditionshown in Figure 2b. Just as the sand runs downholding the lever arm up (Figure 2b), the charges inth capacitor C7 forces transistors Q6, Q8, and Q9 on.As long as the lever arm is up in Figure 2b, the othercircuits are powered through the contact C1 onswitch X1. At first, due to the weight of the sand(similar to capacitor C7 being fully charged), thecontact C2 will open and remain open. Right beforethe sand totally runs out (capacitor C7 has lost mostof its charge), the contact C2 will close, as shown inFigure 2c, and sound an alarm to warn you that thecontact C1 is about to open and turn all the poweroff, including the power to the warning circuit.Eventually all the sand runs out of the “Timer Glass”(capacitor C7 has discharged) and the power isturned off (Figure 2a). To make the timer stay onlonger, you could get a bigger “Timer Glass” (largercapacitor for C7) that holds more sand and replacethe smaller one.

Assume that part of the sand from the “Timer Glass” inFigure 2 is poured into a bucket as shown in Figure 3a.When the bucket has enough sand, it will flip anddump as shown in Figure 3b. Each time it flips, itcloses switch X2, sending the battery voltage to theRing Counter and it strikes the “Drum” producing asound. The bucket in Figures 3a & 3b representscapacitor C6 in the schematic diagram on page 13.Capacitor C6 charges (charging = filling the bucketwith sand) through resistor R20 and discharges(dumping the sand) through resistor R19 and diode

D41. Each time the sand changes buckets, a pulseis sent to the Ring Counter and to the Sound Circuit.When the bucket is empty, the spring returns it to thefilling position shown in Figure 3a. The sand goinginto the bucket will flow slower as the “Timer Glass”in Figure 2 runs out of sand. It will take longer andlonger to fill the bucket as the sand runs out. Thisproduces more space between the pulses sent to thering counter and has the effect of slowing down therotation of the lights, similar to the ivory ball slowingdown on a roulette wheel.

Figure 3 Pulse Generator

THE SOUND CIRCUITIn the sound generator circuit, a 500Hz oscillator isalways running. This oscillator is represented by thespinning wheel in Figure 4a. No sound is heardbecause the spinning wheel is not hitting the drum.When the bucket in Figure 3 dumps sand, the leverarm pushes the spinning wheel against the stop andthe small balls on the spinning wheel hit the drum,producing a high frequency sound (Figure 4b). Thelever arm turns the sound on and representstransistor Q7 in Figure 4c. When the lever arm isremoved, the spring pulls the spinning wheel awayfrom the drum and the sound stops. In much thesame way, transistor Q7 turns off shortly after a pulseis received. This action stops electrical current fromflowing through the piezoelectric buzzer (drum),eliminating the sound. Just before power down,transistor Q7 is turned on and kept on to produce thewarning sound.

THE RING COUNTERIn it’s simplest form, the ring counter can becompared to a circle of buckets with only one bucketfilled with sand as shown in Figure 5a. Because ofthe weight of the sand, the filled bucket hangs lowerthan all of the rest. When a pulse is received fromthe pulse generator circuit, it pushes the sand to thenext bucket as shown in Figure 5b. This processcontinues passing the sand from bucket to bucket ina circle, until no more pulses are received from thepulse generator.

The Light Emitting Diodes (LEDs) are no more thansmall electronic lights. If they are arranged in a circleand connected to a ring counter, they can be used torepresent the ivory ball position on the roulettewheel. When the buckets filled with sand stretch outthe springs in Figure 5, they could also close a switch

as shown in Figure 6. This would light the next lightin the circle and produce the effect of a ball spinningaround the roulette wheel. As the pulses get furtherand further apart, the electronic ball will appear toslow down and eventually stop.

IntroductionThe most important factor in assembling your AK-300 Electronic Roulette Kit is good soldering techniques.Using the proper soldering iron is of prime importance. A small pencil type soldering iron of 25 - 40 watts isrecommended. The tip of the iron must be kept clean at all times and well tinned.

Safety Procedures• Wear eye protection when soldering.• Locate soldering iron in an area where you do not have to go around it or reach over it.• Do not hold solder in your mouth. Solder contains lead and is a toxic substance. Wash your hands

thoroughly after handling solder.• Be sure that there is adequate ventilation present.

Assemble ComponentsIn all of the following assembly steps, the components must be installed on the top side of the PC board unlessotherwise indicated. The top legend shows where each component goes. The leads pass through thecorresponding holes in the board and are soldered on the foil side.Use only rosin core solder of 63/37 alloy.

DO NOT USE ACID CORE SOLDER!

1. Solder all components fromthe copper foil side only.Push the soldering iron tipagainst both the lead andthe circuit board foil.

2. Apply a small amount ofsolder to the iron tip. Thisallows the heat to leave theiron and onto the foil.Immediately apply solder tothe opposite side of theconnection, away from theiron. Allow the heatedcomponent and the circuitfoil to melt the solder.

1. Insufficient heat - thesolder will not flow onto thelead as shown.

3. Allow the solder to flowaround the connection.Then, remove the solderand the iron and let theconnection cool. Thesolder should have flowedsmoothly and not lumparound the wire lead.

4. Here is what a good solderconnection looks like.

2. Insufficient solder - let thesolder flow over theconnection until it iscovered. Use just enoughsolder to cover theconnection.

3. Excessive solder - couldmake connections that youdid not intend to betweenadjacent foil areas orterminals.

4. Solder bridges - occurwhen solder runs betweencircuit paths and creates ashort circuit. This is usuallycaused by using too muchsolder. To correct this,simply drag your solderingiron across the solderbridge as shown.

What Good Soldering Looks LikeA good solder connection should be bright, shiny,smooth, and uniformly flowed over all surfaces.

COMPONENT CHECKMake sure that all components have beenmounted in their correct places.

Make sure that the LEDs have been installedcorrectly. The flat side of the LEDs should be inthe same direction as shown on the top legend.

Make sure that diodes D39 - D43 have not beeninstalled backwards. The band on the diodesshould be in the same direction as shown on thePC board.

Make sure that transistors Q1 - Q9 are installed

with their flat sides in the same direction asmarked on the PC board.

Are capacitors C5 - C8 installed correctly? Thesecapacitors have polarity. Be sure that the negativelead is in the correct hole.

Make sure that the ICs are installed correctly. Thenotch should be in the same direction as shownon the top legend of the PC board.

Put a 9V alkaline battery into the battery holderand push the switch.

TROUBLESHOOTINGOne of the most frequently occurring problems ispoor solder connections.

1. Tug slightly on all parts to make sure that they areindeed soldered.

2. All solder connections should be shiny. Resolderany that are not.

3. Solder should flow into a smooth puddle ratherthan a round ball. Resolder any connection thathas formed into a ball.

4. Have any solder bridges formed? A solder bridgemay occur if you accidentally touch an adjacentfoil by using too much solder or by dragging thesoldering iron across adjacent foils. Break thebridge with your soldering iron.

FINAL ASSEMBLYMount the four plastic spacers onto the fourcorners of the PC board from the foil side with four4-40 x 1/4” black screws (see Figure I).

Punch out and save the chips from the box asshown in Figure J. Slide the PC board into the box

and mount the PC board with four 4-40 x 1/4”screws and four black washers (see Figure K).Cut the strip off of the box as shown.

Tape the box lid shut (see Figure L) and you’reready to go!

PROBABILITYIf among (F+U) equi-probable and mutually exclusiveevents, F is regarded as favorable and U asunfavorable, then for a single event, the probability ofa favorable outcome is:

The probability of an unfavorable outcome is 1 minusthe probability of a favorable outcome. In otherwords, since there is the same chance that anynumber may win on any spin (mutually exclusiveevents), the chances of winning equals the numberof winning numbers divided by the total number ofpossible numbers. Roulette has 38 possiblenumbers that may win. Therefore, F+U is alwaysequal to 38. If you wager on a single number, thechances of winning are 1 divided by 38, or

approximately 97.37%. If you win, the house paysyou 36 times your wager. Multiplying your chance ofwinning times your payback shows the advantage forthe house. In this case, the number is 94.74% whichmeans the house has a 5.26% advantage over theplayers wagering on a single number.

If a wager is placed on black or red, the probability ofwinning is 18 divided by 38 because the number ofblack numbers and the number of red numbers is 18.The probability of a favorable outcome is one color iswagered equals 47.4%. The payout if you win is 2 to1. This yields an advantage for the house of 1 -(0.474 x 2) or approximately 5.26%. As you can see,the house always has a 5.3% advantage.

RULES FOR PLAYING ROULETTEThe object of the game is to increase the value ofyour chips more than any other player. Chips withgold centers are worth $100.00, green centers =$25.00, red centers = $5.00, and white centers areworth $1.00. Each player starts with 1 green, 2 red,and 5 white chips ($40.00). All the rest of the unusedchips belong to the house. Determine how long theroulette table will be open, one hour for example.One person must act as the Croupier (kroo–pya).The Croupier is the attendant who collects and paysthe stakes using the houses money. Since there isno way to predict the outcome of each spin, theCroupier may also be a player. It is possible for aperson to play roulette alone and try to beat thehouse by increasing his total chip value.

The very first action in roulette is to place your wageron the gaming table. The types of bets and theirrates of return are listed in Chart A. The method forplacing a wager is shown in Chart B. Placing wagersstarts when the Croupier announces “Place yourWagers!”. All wagers must be in place when theCroupier announces “No more wagers!”.

After all wagers have been placed, the start button ispressed by the Croupier and the lit LED thatrepresents the ivory ball races around the circleadding excitement and anticipation to the game. Thenumber next to the lit LED, when the motion stops, isthe winning number. All wagers are paid by theCroupier according to the rates of return listed inChart A.

The game ends when the house runs out of chips orthe predetermined time period expires. To prevent aperson from doubling his wager until he wins, amaximum limit of $100 should be placed on eachwager. When a player loses all of their chips, theymay borrow from other players at whatever interestrate that player demands. At no time may a playerborrow more than $40.00. Once a player owes$40.00 and has lost all of their chips, they arebankrupt and can no longer place wagers. Abankrupt player may assume the position of Croupierand earn $1.00 from the house for every 10 spins toremain in the game. A Croupier who is not bankruptis paid no salary by the house.

WORD GLOSSARY

Capacitor An electrical component that canstore electrical pressure (voltage)for periods of time.

Cold Solder Joint Occurs because insufficient heatwas applied or the connectionwas moved before the solder hadset. Connection looks crystalline,crumbly, or dull.

Flux A substance that is used tocleanse the surface of oxidebefore it is soldered. Alwaysused in electronics work. Most ofthe solder used in electronics hasflux built right into it.

Heat Sinking A process of keeping thecomponent from becomingoverheated during soldering. Anymetal object that can be clampedto the component lead will workas an effective heat sink. Analligator clip or pliers work well.

Integrated Circuit (IC) A type of circuit in whichtransistors, diodes, resistors, andcapacitors are all constructed ona semiconductor base.

Jumper Wire A wire that is connected from oneplace to another on a PC board,thereby making a connectionbetween two pads.

LED Common abbreviation for lightemitting diode.

Light Emitting Diode A diode made from galliumarsenide that has a turn-onenergy so high that light isgenerated when current flowsthrough it.

Oxidation Most metals, when exposed toair, form an oxide on their surfacewhich prevents solder fromadhering to the metal.

Polarity The division of two opposingforces or properties.

Printed Circuit Board A board used for mountingelectrical components.Components are connectedusing metal traces “printed” onthe board instead of wires.

Resistor Component used to control theflow of electricity in a circuit. It ismade of carbon.

Rosin Core Solder The most common type of solderused in electronics generallyreferred to as 63/37 rosin coresolder.

Solder A tin/lead alloy that melts at avery low temperature, used tojoin other metals together. Itproduces excellent electricalconnections.

Solder Bridge An unwanted solder connectionbetween two points that are closetogether.

Solder Melting Point The temperature at which atin/lead alloy (solder) melts. Thecommon solder used inelectronics (63% tin / 37% lead)has a melting point of 370OF.

Solder Wick Braided wire coated with flux toeffectively remove solder from aconnection.

Soldering The process of joining two ormore metals by applying solder tothem.

Tack Soldering A connection where the lead orwire does not have anymechanical support.

Tinning the Tip A process of coating thesoldering iron tip with solder tominimize the formation of oxideon the tip, which would reducethe amount of heat transfer.

Transistor An electronic device that uses asmall amount of current to controla large amount of current.

Wire Gauge Refers to the size of the wire. Thebigger the number, the smallerthe diameter of the wire.18 gauge to 24 gauge isgenerally used for hook-up inelectronics.
