This year at the Trunk O Treat at my church I made the game "Simon Says Narnia". This is the electronic game Simon by Hasbro built into a wooden wardrobe like in the movie The Chronicles of Narnia, "The Lion, the Witch and the Wardrobe" by C.S. Lewis.

Step 1: How the Electronic Simon Game Works

The Simon game lights its colored buttons with 3.5VDC (On State) and 0V (Off State). With this condition a TTL logic device can be used with the Simon game. I connected wires to each color of the (+) side of the small Simon light bulbs. I tied each of these (control +) wires to separate TTL MOSFET Transistors (On Semiconductor TTL Power MOSFET part# MTP10N10EL)to drive higher current load. I need around 300mA@12VDC to illuminate the game pushbutton switches and around 850mA for the LED's in each the picture frame.

Step 2: Build the Wardrobe

The wardrobe is constructed from 1"x2" furring strips to make a low cost frame with plywood sheeting on the outside. The sheeting is 1/8" project plywood that comes in 4Ft X 8Ft sheets. The dimensions are noted on the drawing. The over all size is 4Ft wide by 6Ft tall and 16In deep. The wardrobe has two doors that close and open. I used double hinges so the door will swing open to 270 degrees.

Step 3: Build the Game Part1

I took apart the handheld Simon game and added external button controls mounted in a wood Wardrobe. The large 2" diameter color Simon game pushbutton are lit by 12VDC and the LED's around the picture frame for each Narnia character. The picture of Lucy with yellow LED's in the picture frame is connected to the yellow Simon game button for function. The picture of Edmund with Blue LED's in the picture frame is connected to the blue Simon game button for function. The picture of Susan with red LED's in the picture frame is connected to the red Simon game button for function. The picture of Peter with Green LED's in the picture frame is connected to the green Simon game button for operation.
The Simon games low voltage lights drive the TTL MOSFET Transistors to turn on and off per the color light.

Step 4: Build the Game Part2

The game is made with rubber dome chiclet switch pads. The conductive traces on the PCB are normally separated by a non-conductive gaps that when the rubber membrane dome switch is pressed make contact with the two traces to form a complete circuit. I soldered 30awg wire from each trace per pad. (Two wire per Pad) For each of the function game buttons I soldered two wires to make the switch pad work. The function buttons I used was the four color game buttons, game button, level button, start button, and last play button. These button wires were soldered to 18awg wire and insulated with shrink tubing. I labeled the set of two wires for each button function and connect them to the correct switch for operation.

Step 5: Picture Frames of the Narnia Characters

The picture frames are made from cardboard cut 2" wide to make a frame that is 12" x 16". I installed three white LED's in the 12" sides of the frame and installed four white LED's in the 16" sides of the frames. The colored LED's are installed 1.25" from the top of the 2" wide cardboard. The colored LED's are located closest to the picture. I installed six colored LED's in the 12" frame sides and ten colored LED's in the 16" frame sides. I poked the leads of the LED's through the cardboard and wired/soldered then in parallel with own 471-ohm per LED. I covered the wires that make of the LED frames with white paper to cover the wires.

Each picture frame has two sets of (+ -) power wires one for white LED's for frame lights and the other set (+ -) for color button functions. I download the pictures from Narnia websites.

Step 6: Game Buttons

The function buttons I used was the four color game buttons, game button, level button, start button, and last play button.

Step 7: Simon Says Narnia Game Video

Watch the game light up when you press the last game button.

Step 8: LED Light Strip, LED Light Bars

LED Light Strip or LED Bars:

Installed inside the wardrobe on the sides and top are LED light strips. The LED light strips are constructed easily and work and look fantastic at a low cost.

The Narnia sign has three light strips 35" long inside. I printed out the sign with banner paper and the LED light shines through the banner paper. The banner paper is taped to the open side of a cardboard box.

The LED's are spaced every 2" on center starting 1/4" from the end. I marked each LED location on the front side of the vinyl divider. I made a wood drill jig that is the same as the LED lead spacing. I drill the two holes per LED. I inserted the LED through the flat face side of the vinyl divider and bent the shorter lead (LED cathode -) to keep the LED's from falling out. I wrapped around each cathode LED lead with sold bare cooper wire that is 18awg to 22awg and soldered it together.

The Vinyl Divider H-Channel #P235 (Home Depot) is 8ft long. The flat side is the face where the LED is mounted to and the back side with the two groves

Step 9: LED Light Strip, LED Light Bars Circuit

See the circuit layout drawing. I put tape over the exposed wires on the back side. This technique makes LED Strip or LED Bar Lights easy to make. I can make a complete 36" long LED Strip light in around 20 Minutes. These LED light strips produce a lot of light and look fantastic......
