THIS STYLE OF PROJECTOR IS MORE STABLE AND SLIGHTLY HARDER TO MAKE. IMAGES OF A FINISHED PROTOTYPE BELOW. SORRY NO PICTURES OF THIS ONE IN ACTION JUST YET.
MATERIALS LIST
1. THICK CORRUGATED CARDBOARD (CARDBOARD CAN BE REPLACED WITH ANYTHING STURDY AND NOT TOO HEAVY EG. THIN FIBERBOARD/WOOD PANELING ETC.)
2. MAGNIFYING GLASS (A FRESNEL LENS IS RECOMMENDED)
3. BLACK PAINT
4. DUCT TAPE
5. SATINY KNIFE OR SHARP KNIFE
6. RULER
7. PENCIL OR TEXTA
STEP 1
FIRST MEASURE THE HEIGHT AND WIDTH OF YOUR TV SCREEN. MAKE SURE TO MEASURE JUST THE SCREEN AND NOT THE BOX AROUND IT.
STEP 2.
THEN ON THE CARDBOARD/WOOD ETC. MARK OUT YOUR MEASUREMENTS FOR THE SCREEN HEIGHT AND WIDTH AND SET THE DEPTH TO 18 INCHES. CUT 2 OF EACH WITH YOUR STANLEY KNIFE. (WHERE I HAVE WRITTEN "TV HEIGHT" AND "TV WIDTH" I AM REFERRING TO SCREEN SIZE.)
STEP 3.
STEP 4.
NOW WE WILL MAKE THE FRONT OF THE BOX. THE FRONT OF THE BOX MEASURES THE HEIGHT AND WIDTH OF YOU TV SCREEN AND FITS ON ONE END OF THE PROJECTOR BOX YOU HAVE JUST MADE. MARK AND CUT OUT THE RECTANGULAR SHAPE TO THE WIDTH AND HEIGHT MEASUREMENTS.
AFTER YOU HAVE MARKED AND CUT OUR THE PIECE IT IS THEN TIME TO CENTRE A SQUARE HOLE. DRAW TWO LINES ON THE RECTANGLE SHAPE FROM CORNER TO CORNER AS SHOWN BELOW. THIS WILL GIVE YOU A GOOD GUIDE TO GET THE HOLE CENTRED.
STEP 5.
STEP 6START BY MARKING OUT THE
MEASUREMENTS ON THE CARDBOARD/WOOD WITH A RULER AN THEN CUT
OUT THE SQUARE SHAPE. CREATE A STRAIGHT LINE FROM ONE CORNER
TO OPPOSITE CORNER TO FORM A CROSS ON THE FOCUSING CUBE,
CENTRE THE MAGNIFYING LENS WITH HELP FROM THE CROSS. NOW TRACE
AROUND THE MAGNIFYING LENS SO THAT YOU HAVE A DRAWN CIRCLE ON
THE FOCUSING CUBE AND NOW CUT OUT THE CIRCLE. NOTE : THE
MAGNIFYING LENS MUST FIT SNUGLY INTO THE HOLE.
NOTE: IF YOU ARE MAKING THIS FROM
CARDBOARD, YOU CAN ANGLE THE STANELY KNIFE WHEN CUTTING THE
CIRCLE SO THAT THE HOLE IN BACK SIDE OF THE CARDBOARD IS
SLIGHTLY LARGER THAN THE FRONT. I HAVE TRIED TO DEMONSTRATE
THIS IN THE PICTURE BELOW.
STEP 7.
TAKE ALL PIECES PAINT THEM BLACK. BOTH SIDES IF YOU WISH BUT PAINTING THE INSIDES ONLY IS ESSENTIAL FOR A GOOD PICTURE. THE BLACKER THE BETTER. MAKE SURE YOU USE FLAT OR MATT BLACK PAINT.
STEP 11.

THEN ON THE CARDBOARD/WOOD ETC. MARK OUT YOUR MEASUREMENTS FOR THE SCREEN HEIGHT AND WIDTH AND SET THE DEPTH TO 18 INCHES. CUT 2 OF EACH WITH YOUR STANLEY KNIFE. (WHERE I HAVE WRITTEN "TV HEIGHT" AND "TV WIDTH" I AM REFERRING TO SCREEN SIZE.)
YOU WILL THEN HAVE 4 INDIVIDUAL
PIECES THAT WILL FORM THE SIDES OF THE CUBE, TOP,BOTTOM, LEFT
AND RIGHT. WHEN WE PUT IT TOGETHER IT WILL LOOK LIKE THIS. I
HAVE COLOURED THE DIAGRAM ONLY TO HELP YOU VISUALIZE THE BOX
BETTER.
NOW WE WILL MAKE THE FRONT OF THE BOX. THE FRONT OF THE BOX MEASURES THE HEIGHT AND WIDTH OF YOU TV SCREEN AND FITS ON ONE END OF THE PROJECTOR BOX YOU HAVE JUST MADE. MARK AND CUT OUT THE RECTANGULAR SHAPE TO THE WIDTH AND HEIGHT MEASUREMENTS.
AFTER YOU HAVE MARKED AND CUT OUR THE PIECE IT IS THEN TIME TO CENTRE A SQUARE HOLE. DRAW TWO LINES ON THE RECTANGLE SHAPE FROM CORNER TO CORNER AS SHOWN BELOW. THIS WILL GIVE YOU A GOOD GUIDE TO GET THE HOLE CENTRED.
THE MARK AND CUT OUT THE HOLE
WITH A STANELY KNIFE. THE SIZE OF THIS SQUARE HOLE SHOULD BE
12INCHES(HEIGHT) X 12INCHES(WIDTH) FOR LARGER TV'S AND
7INCHES(HEIGHT) X 7INCHES(WIDTH) FOR SMALLER TV'S.
IT WILL FIT ON THE FRONT OF THE
FIRST BOX WE MADE (TO MAKE THE FIFTH SIDE).
NOW WE WILL MAKE THE FOCUSING
CUBE. IT IS ANOTHER BOX JUST LIKE THE ONE YOU HAVE JUST MADE,
BUT SMALLER AND THE END OF THIS BOX HAS A CIRCLE CUT IN THE
MIDDLE FOR THE LENS.
THE HEIGHT AND WIDTH OF THIS
ONE WILL BE 12INCHES(HEIGHT) X 12INCHES(WIDTH) X
8INCHES(DEEP)FOR LARGER TV'S AND 7INCHES(HEIGHT) X
7INCHES(WIDTH) X 8INCHES(DEEP)FOR SMALLER TV'S. THE HOLE IN
THE FRONT WILL BE THE SIZE OF YOUR LENS. SEE STEP 6 ON HOW TO
CORRECTLY CENTRE YOUR LENS. SO CUT 4 PIECES 8 INCHES DEEP AND
EITHER 7 INCHES IN WIDTH FOR SMALLER TV'S OR 8 INCHES DEEP AND
EITHER 12 INCHES IN WIDTH FOR LARGER TV'S. YOU WILL THEN HAVE
FOUR PIECES THAT MAKE UP THE TOP, BOTTOM LEFT AND RIGHT SIDES
OF THE FOCUSSING CUBE. NOW MAKE THE FRONT PART OF THE BOX THAT
HOLDS THE LENS BY FOLLOWING STEP 6.
TAKE ALL PIECES PAINT THEM BLACK. BOTH SIDES IF YOU WISH BUT PAINTING THE INSIDES ONLY IS ESSENTIAL FOR A GOOD PICTURE. THE BLACKER THE BETTER. MAKE SURE YOU USE FLAT OR MATT BLACK PAINT.
STEP 8.
ONCE THE PIECES ARE DRY, ITS
TIME TO STICK THEM TOGETHER. USING SMALL PIECES OF DUCT TAPE,
FORM THE SIDES OF THE BOX (BLACK ON THE INSIDE) AND STICK THE
SMALL PIECES OF DUCT TAPE ON SO IT HOLDS ITS SHAPE. REPEAT
THIS STEP FOR BOTH SMALL AND LARGER BOXES.(YES! THERE SHOULD
BE TWO OF THEM).
STEP 9.
NOW THAT THE BOXES ARE HELD IN
PLACE REINFORCE AND CLOSE THE GAPS BY RUNNING A STRIP OF DUCT
TAPE DOWN EACH JOIN.
STEP 10.
NOW TAKE THE FOCUSING CUBE
FRONT AND INSERT THE MAGNIFYING LENS IN IT. THEN ATTACH THIS
PIECE TO THE FRONT OF THE FOCUSING CUBE.
TURN YOUR TV UPSIDE DOWN.(IT
WON'T DO ANY MAJOR DAMAGE, IF YOU DON'T WANT TO DO THIS THERE
IS AN ALTERNATIVE).WITH DUCT TAPE ATTACH THE BOX TO THE SCREEN
OF YOUR TV MAKING SURE TO CLOSE ANY GAPS SO THAT NO LIGHT WILL
ESCAPE. THEN INSERT THE FOCUSSING CUBE INSIDE THE BOX. YOU ARE
NOW READY TO USE YOUR PROJECTOR.
STEP 12.
SOMETIMES IT IS DIFFICULT TO
PREDICT WHAT THE BEST POSITION FOR THE TV AND FOCUSING CUBE
SHOULD BE TO GET A PICTURE. I ALWAYS START BY LINING UP THE
OUTSIDE END OF THE BOX ABOUT 2 INCHES FROM THE WALL, THE
PICTURE IS VERY SMALL BUT AT LEAST YOU KNOW ITS WORKING. THEN
SLOWLY MOVE THE TV AND PROJECTOR AWAY FROM THE WALL UNTIL THE
DESIRED SCREEN SIZE IS ACHIEVED. THEN USE THE FOCUSING CUBE TO
FOCUS THE IMAGE. IT WILL TAKE A LITTLE FIDDLING AROUND WITH
BUT YOU'LL GET IT.
DON'T WANT TO TURN YOUR
TV UPSIDE DOWN? HERE ARE THE ALTERNATIVES.
THE FIRST ALTERNATIVE IS TO PUT
YOUR TV ON ITS BACK WITH THE PROJECTOR ON FACING THE CEILING.
THIS WILL THEN PROJECT THE IMAGE INTO THE CEILING. YOU COULD
LAY BACK AND WATCH THE MOVIE ON THE CEILING OUR PLACE A MIRROR
AT A 45 DEGREE ANGLE AT THE END OF THE PROJECTOR. THE IMAGE
WILL THEN BE PROJECTED ONTO THE MIRROR AND BOUNCE OFF ONTO THE
WALL REVERSING THE IMAGE TOP TO BOTTOM.
YOU MAY ALSO CHOOSE TO DO THE FOLLOWING
THIS METHOD WILL ALLOW YOU TO KEEP YOUR TV IN IT'S NORMAL POSITION.
IF YOU FEEL YOU ARE TECHNICALLY INCLINED, THIS IS HOW THIS IS DONE (VERY SIMPLE): REFER TO THE PICTURE OF THE INSIDE OF MY TV. WHAT YOU ARE LOOKING AT IS THE INSIDE OF A 13" TV. BELOW IS AN IMAGE OF THE INSIDE OF A TV.
NOTE: THE COLOR OF THE WIRES MAY BE DIFFERENT ON YOUR TV. MAKE SURE YOU ARE SWITCHING THE SAME TWO WIRES. CAUTION: ALSO BE SURE THAT THE TV IS OFF AND UNPLUGED. FAILURE TO DO SO COULD CAUSE SEVERE INJURY INCLUDING POSIBLE DEATH FROM ELECTRICAL SHOCK! OR IT COULD JUST DESTROY YOUR TELEVISION! :-(

THE ONLY OTHER ALTERNATIVE IS
TO WATCH THE SCREEN UPSIDE DOWN. ADDING ANOTHER MAGNIFYING
LENS WILL NOT TURN THE IMAGE AROUND THE RIGHT WAY.
HOW TO INSERT THE FRESNEL LENS.
MEASURE
THE DIAMETER OF THE 5TH BIGGEST CIRCLE ON THE FRESNEL LENS AND
HALF THE AMOUNT TO GET THE MEASUREMENT OF THE RADIUS. SET YOUR
COMPASS AT THIS MEASUREMENT AND PLACE THE POINT OF THE COMPASS
ON THE MIDDLE MARK OF THE FRONT PANEL. DRAW YOUR CIRCLE AND
CUT IT OUT. USE DUCT TAPE TO HOLD THE RECTANGULAR SHAPED LENS
IN PLACE. (USING DUCT TAPE WILL ALLOW YOU TO TURN OR MOVE THE
LENS IF YOU HAVE TO. HOME INSTRUCTION 2 INSTRUCTION 3 INSTRUCTION 4 TROUBLESHOOTING
