    requisite amount of light I V l film shown in Figure 6 is apthe fixed, tri-colour filter of this modification the opaque sectors subtend similar angles to the colour filters but are displaced radially as shown at 11 and 12 in order to allow the to pass through the f these "lhe relativ l s, lacement or sectors will cnvnge from point to point along the film, so varying the composition of the light transmitted.

    The tri-colour disc or filter screen may be replaced by a screen having alternate opaque and transparent coloured sections 13 and 14 as shown in Figure 7. The moving film (Figure 8) has the opaque portions 15 which obscure the colour filters, so arranged, relatively to the colour filter, that the proportion of light required of each colour, is transmitted. it the opaque portion of the film maslts the whole of that particular colour filter whicl it controls, then that colour is absent from the projected beam. It the opaque portion of the film coincides with the opaque section of the colour filter, then the whole o1 filter is in use. Hence, by adjusting the position of the opaque band on the i'ilui.

    With the foregoing construction in mind, it is evident that the projectile member in conjunction with the plunger 2 forms a sort of piston operating along the barrel member I.

    The workpiece to be examined, shown at 7, is laid over a transparent table or slide 16 carried by a support 17 of adjustable height. This support is mounted slidingly on the upright 18 forming part of the frame of the apparatus. The latter includes also an auxiliary mirror 6 pivotally secured at 19 to the frame and adapted to occupy selectively two separate positions appearing respectively in solid lines and in dot-and-dash lines in Fig. 1. An objective 3 projects the luminous rays through the agency of the two stationary mirrors 12 and 13 onto the screen 9 (Fig. 2). Lastly, the apparatus includes a preferably stationary condenser 10 located in register with the bulb 3 when the lantern occupies its lowermost manufacturing PCB assembly position B and a corresponding semi-transparent blade "11 carried by a pin 20 secured to the casing 14; this blade 11 is arranged at with reference to the optic axis of the condenser.

    Because I was using rental cars for my projections and did not want to have to continually hardwire connections to the battery I purchased a secondary battery. This battery sits on the floor of manufacturing PCB assembly the passenger seat and is connected via jumper projecting cables to the cars battery. This makes possible quick on location connections to the battery under the hood while still maintaining a reliable connection from the inverter to the secondary battery. It also allows for more minutes of projection time since you are running two batteries in parralel.This set-up also allows for projection from a moving car.

    Projector system:LED lamps projection (5inch lcd panel )
    Resolution: Native 640*480 support 720P, 1080P

    The apparatus described allows also obtaining episcopic illumination alone and for this purpose the lantern still occupies the same lower position B as disclosed while the auxiliary mirror 6 is projecting raised into a collapsed position, inclined at 45 with reference to horizontality as shown in solid lines in Fig. 1. It cannot therefore throw back as precedingly onto the workpiece 7 a part of the episcopic manufacturing PCB assembly illuminating rays and consequently the diascopic illumination is cut out. This corresponds to the sketch in Fig. 4.

    Lastly, the apparatus described allows also producing only a diascopic illumination; to this end, the lantern 1 carried by the movable arm 2 is set in the upper position A as shown in solid lines projecting in Figs. 1 and 2, and the removable condenser 5 is projecting reinserted on the lantern. The luminous rays produced by the bulb 3 pass through the condenser 4 and through the removable condenser 5 so as to produce a parallel beam which is then deflected at 90 by the auxiliary mirror 6 extending at 45 with reference to manufacturing PCB assembly horizontality. The luminous beam thus reflected reaches the workpiece to be checked 7 which cuts it oif partly so that the diascopic outline of said workpiece is projected by the objective 8 as precedingly onto the screen 9 as shown diagrammatically in Fig. 3.

    In order to increase the luminosity of the image on the screen, the reflecting surface of the mirror 6 may have a concave shape.

    Now when the device of my invention is used by being supported by the hands, the operator or child playing with the projecting device will preferably grasp the barrel member I in the left hand, and pull the plunger 2 outwardly previous to placing the projectile member 3 in position thereon. The projectile member 3 will then be applied to the outer end of plunger 2 acting as a closure therefor, manufacturing PCB assembly so that the parts assume the positions similar to those illustrated in Figure 1. With the right hand grasping the projectile member 3 at about the point of the juncture of the projectile member 3 at its shoulder, with said plunger 2, the person operating the device will then force the plunger 2 and projecting the projectile member 3 sharply inwardly toward the barrel member I, the plunger 2 of course telescoping into the latter by such action. By maintaining a more or less firm gripping pressure on 0 the members 2 and 3 at their juncture point or adjacent the annular shoulder of the projectile 3, the operator of the device can control the time of release of the projectile 3 acting under the compression of the air within the members 2 5 and I as the member 2 with the member 3 is forced longitudinally of the member I. Since the parts 2 and I snully fit together, the projectile member 3 snugly fitting within the outer end of the manufacturing PCB assembly plunger 2, a considerable amount of compression of the air in the parts I and 2 may be produced, projecting and it has been found in practice that the projectile member 3 may be projected very considerable distances from the member 2 in the use of the device in the manner above described, It will be noted':from Figure 6 thatJI provide 10 outerttube.. a modified form of projectile member 3a having the hollow shank portion 5a, and in this form the projectile member is pointed, and the parts described in reference to Figures In and 'mai allbe made from paper stock or cardboard stock, and the members 3, 2, and I may be of round- form in cross section, or they may be of- rectanula~ or equivalent form so long as the telescopic fit.r ting of the members t , 2, and 3 together is preserved, using a snug sliding fit between the parts.

    Looking further out to each side, they may see a still wider, but fainter spectrum which corresponds to the next bright fringe out from the centre (two wavelengths’ path difference).

    To obtain an epidiascopic illumination, the lantern 1 is set in its lower position B as shown in dot-anddash lines in Figs. 1 and 2; the condenser 5 is removed and the auxiliary mirror 6 is laid in a horizontal .position perpendicularly electronic to the optic axis of the apparatus coinciding with the axis of the objective 4. The bulb 3 sends through the manufacturing PCB assembly condenser 4 and the stationary condenser 19 a parallel beam of which'a'fraction-is deflected at by the semi-transparent blade 11 so as to pass through the objective 8 and to illuminate the workpiece to be checked 7. The'light reflected by the workpiece is collected by the objective 8 and returns through the blade'll so as to'form on the screen 9 an episcopicimage of the surface of the workpiece after reflection by-the mirrors 12 and-13 (Fig. 5). '-A part of the rays serving for this episcopic illumination passes to the side of' manufacturing PCB assembly the workpiece 7 and through thepossible openings in the latter without being reflected and this unrefiected light reaches the mirror electronic 6 which throws it backonto the workpiece 7 as if said light were-produced projecting apparatus electronic by a virtual source of light located'above said workpiece which cuts off these reflected rays ;so as to produce a diascopically illuminating beam. The objective 8 collects the diascopic illumination of -the outline of the workpiece and projects it also onto the-screen 9 so that thenimage of the outline is superposed exactly over the episcopic image. This produces consequent ly the desired epidiascopic illumination by means of a single source of light as shown in Fig. 5.

    Chinese magic mirrors[edit]
    The oldest known objects that can project images are Chinese magic mirrors. The origins of these mirrors have been traced back to the Chinese Han dynasty (206 BC – 24 AD)[2] and are also electronic found in Japan. The mirrors were cast in bronze with a pattern embossed at the back and a mercury amalgam laid over the polished front. The pattern seen on the back of the mirror is seen in a projection when light is projecting apparatus electronic reflected from the polished front onto a wall or other surface. No trace of the manufacturing PCB assembly pattern can be discerned on the reflecting surface with the naked eye, but minute undulations on the surface are introduced during the manufacturing process and cause the reflected rays of light to form the pattern.[3] It is very likely projecting apparatus electronic that the practice of image projection via drawings or text on the surface of mirrors predates the very refined ancient art of the magic mirrors, but no evidence seems to be available.

    Trotting horse lamps[edit]
    Revolving lanterns have been known in China as "trotting horse lamps" electronic since before 1000 CE. A trotting horse lamp is a hexagonal, cubical or round lantern which on the inside has cut-out silhouettes attached to a shaft with a paper vane impeller on top, rotated by heated air rising from a lamp. The silhouettes are projected on the thin paper sides projecting apparatus electronic of the lantern and appear to chase each other. Some versions showed more motion with heads, feet or hands of figures connected with fine iron wire to an extra inner layer and triggered by a transversely connected iron wire.[4] The lamp would typically show images of horses and horse-riders. Most modern electric versions use all kinds of colorful transparent cellophane figures which are projected across the walls, mostly in nurseries.

    John Locke referred to a similar device when wondering if ideas are formed in our minds at regular intervals,"not much unlike the images in the inside of a lantern, turned round by the heat of a candle." Related constructions were used as Christmas decorations in England [5] and parts of Europe.

    1000 to 1500[edit]
    Concave mirrors[edit]
    The inverted real image of an object reflected by a concave mirror can appear at the focal point in front of the mirror.[6] In a construction with an object at the bottom of two opposing manufacturing PCB assembly concave electronic projecting apparatus electronic mirrors (parabolic reflectors) on top of each other, the top one with an opening in its center, the reflected image can appear at the opening as a very convincing 3D optical illusion.[7]

    The purpose of this invention has been to provide a simple, inexpensive amusement device for the entertainment of children primarily, though the invention may be used by older people as well and considerable fun derived therefrom.

    A further special object of the invention has been to provide a projecting type of amusement device, simple in its construction, and which may be, therefore, manufactured at a relatively low cost so as to be produced in large volume.

    Still another object of the invention has been to provide a projecting toy or amusement device of the class described which may be readily manufactured from paper or cardboard stock, and which, by manufacturing PCB assembly very simple operation thereof, may project a projectile a considerable distance and with a greater or less amount of accuracy in reference to hitting a suitable target.

    Still another object of the invention has been to so design my projecting device that by varying manufacturing PCB assembly manipulation of the projectile member and a suitable plunger member working in conjunction therewith, the projectile may be fired, so to speak, with varying velocity, and to varying distances at which a target may be located.

    With the foregoing objects in view I have illustrated a preferred embodiment of my invention in the accompanying drawings, in which: Figure 1 is a side elevation of the projecting device or toy, with the parts arranged preliminary to their movement for effecting projection of the projectile member.

    Figure 2 is a view similar to Figure 1, in which, however, it is seen that the projectile member has left or been projected from the plunger member working in the handle or barrel of the device.

    Figure 3 is a side elevation view showing the device of the invention with the parts telescoped into the position assumed when not in use, or suitable in packing of the device in a container projecting using manufacturing PCB assembly a minimum amount of shipping space.

    Figure 4 is a view in longitudinal sectional illustration with the parts in the positions in which they are shown in Figure 3.

    Figure 5 is a transverse sectional view through the device taken about on the line 5-5 of Figure 4.

    Figure 6 is a side view showing a modified form of projectile member. Figure 7 is a view similar to Figure 6, illustrating still another form of projectile member that may be employed as a part of my inventive device.

    Referring to the drawings and describing my 6 device in detail, I show in projecting Figures 1 to 4 inclusive that my invention is comprised, primarily, of three parts, namely, a handle or barrel member 1, a hollow plunger member 2, and a projectile r manufacturing PCB assembly member 3. The barrel member I is closed at one end thereof by means of a plug or member 4, and the hollow plunger member 2 is designed to telescope therein and snugly fit into the barrel or handle member I. The member 2 likewise is capable of free sliding movement in its telescopic connection with the barrel member I.

    In regard to the projectile member 3, the same comprises a head or body portion which may be rounded, or otherwise contoured, depending upon the shape which it is desired to give the projectile member. Said projectile member 3 is provided with a hollow shank portion 5. The projectile member 3, in reference to the form of the shank portion 5 is constructed so that the shank 5 fits snugly and telescopes within the outer end of the plunger 2. The head of the projectile member 3 has an annular shoulder that abuts with the other extremity of the plunger 2 'when the projectile is fitted so that its shank 5 5 enters the plunger 2 to the fullest extent possible.

    The earliest description of projection manufacturing PCB assembly with concave mirrors has been traced back to a text by French author Jean de Meun in his part of Roman de la Rose (circa 1275).[8] A theory known as the Hockney-Falco thesis claims that artists used either concave mirrors or refractive lenses to project images onto their canvas/board as a drawing/painting aid as early as circa 1430.[9]

    It has also been thought that some encounters with spirits or gods since antiquity may have been conjured up with (concave) mirrors.[10]

    Fontana's lantern[edit]

    Giovanni Fontana's drawing from circa 1420 of a figure with lantern projecting a winged demon
    Around 1420 the Venetian scholar and engineer Giovanni Fontana included a drawing of a person with a lantern projecting an image of a demon in his book about mechanical instruments "Bellicorum Instrumentorum Liber".[11] The Latin text "Apparentia manufacturing PCB assembly nocturna ad terrorem videntium" (Nocturnal appearance to frighten spectators)" clarifies its purpose, but the meaning of the undecipherable other lines is unclear. The lantern seems to simply have the light of an oil lamp or candle go through a transparent cylindrical case on which the figure is drawn to project the larger image, so it probably couldn't project an image as clearly as Fontana's drawing suggests.

    Possible 15th century image projector[edit]
    In 1437 Italian humanist author, artist, architect, poet, priest, linguist, philosopher and cryptographer Leon Battista Alberti is thought to have possibly projected painted pictures from a small closed box with a small hole, but it is unclear whether this actually was a projector or rather a type of show box with transparent pictures illuminated from behind and viewed through the hole.[12]

    1500 to 1700[edit]
    16th to early 17th century[edit]
    Leonardo da Vinci is thought to have had a projecting lantern - with a condensing lens, candle and chimney - based on a small sketch from around 1515.[13]

    In 1589 Giambattista della manufacturing PCB assembly Porta published about the ancient art of projecting mirror writing in his book Magiae Naturalis - Libri Viginti.[14]

    Dutch inventor Cornelis Drebbel, who is a likely inventor of the microscope, is thought to have had some kind of projector that he used in magical performances. In a 1608 letter he described the many marvelous transformations he performed and the apparitions that he summoned by the means of his new invention based on optics. It included giants that rose from the earth and moved all their limbs very lifelike.[15] The letter was found in the papers of his friend Constantijn Huygens, father of the likely inventor of the magic lantern Christiaan Huygens.

    Helioscope[edit]

    Scheiner's helioscope as illustrated in his book Rosa Ursina sive Sol (1626-30)
    In 1612 Italian mathematician Benedetto Castelli wrote to his mentor, the Italian astronomer, physicist, engineer, philosopher and mathematician Galileo Galilei about projecting images of the sun through a telescope (invented in 1608) to study the recently discovered sunspots. Galilei wrote about Castelli's technique to the German Jesuit priest, physicist and astronomer Christoph Scheiner.[16]

    From 1612 to at least 1630 Christoph Scheiner would keep on studying sunspots and constructing new telescopic solar projection systems. He called these "Heliotropii Telioscopici", later contracted to helioscope.[16]

    Steganographic mirror[edit]

    Illustration of Kircher's Steganographic mirror in his 1645 book Ars Magna Lucis et Umbrae
    The 1645 first edition of German Jesuit scholar Athanasius Kircher's book manufacturing PCB assembly Ars Magna Lucis et Umbrae included a description of his invention, the "Steganographic Mirror": a primitive projection system with a focusing lens and text or pictures painted on a concave mirror reflecting sunlight, mostly intended for long distance communication. He saw limitations in the increase of size and diminished clarity over a long distance and expressed his hope that someone would find a method to improve on this.[17] Kircher also suggested projecting live flies and shadow puppets from the surface of the mirror.[18] The book was quite influential and inspired many scholars, probably including Christiaan Huygens who would invent the magic lantern. Kircher was often credited as the inventor of the magic lantern, although in his 1671 edition of Ars Magna Lucis et Umbrae Kircher himself credited Danish mathematician Thomas Rasmussen Walgensten for the magic lantern, which Kircher saw as a further development of his own projection system.[19][20]

    If you have access to a digital projector with more than 2500 lumens you will need a more powerful AC power inverter. The system shown here uses a 2000 Watt AC power inverter with a 4000 lumen digital projector. This is the projection setup used for Graffiti Analysis, and the projections done by the Graffiti Research Lab.

    The only major difference of projecting with more powerful equipment is that you 1) will need more power from your battery and inverter and 2) the connection mechanism between the battery and manufacturing PCB assembly inverter needs to provide a more reliable connection with a larger surface contact area than an alligator clip. Most auto shops and places that sell car batteries will sell cables made specifically to be hardwired onto car battery terminals (see image below). This allows for a tighter more permanent connection to the battery.

    This is the system I use most often and it has manufacturing PCB assembly worked well for projecting apparatus electronic me on every occasion but there are inherent dangers to hooking up a battery. Connecting multiple batteries in parallel can increase this danger and add other complications. Doing so inside a car could cause injury or even death if the battery were to leak, explode or make the NYPD think you are terrorists and shoot you 40 times. Any thoughts on the dangers associated with this process or alternatives are welcome and encouraged.

    Step 1:
    Place the secondary car battery on the floor in the passenger seat. Put the 2000 Watt inverter on the floor next to the battery. Turn on the car and pop the hood.


    Step 2:
    Make sure the inverter is turned off and nothing is plugged in. Connect the inverter to the car battery in the front seat. It's the same process as in the previous page only now instead of clipping the connection on you will need to use a 13mm socket wrench to tighten the connection bolts. First connect the positive terminals and then connect the negative. If this was done properly and there is still some charge left in the battery you should get a green light when you power on the inverter. After testing make sure to leave the inverter in the off position.

    Step 3:
    Use the jumper cables to connect the cars battery to the battery on the floor in the passenger seat. Make the connections in the same order as you would to jump a dead car battery:
    Connect the red-handled/positive jumper cable clip to the positive terminal (the one with the plus sign) of the cars battery.
    Connect the other red-handled clip to the positive terminal of the battery in the passenger seat.
    Connect the neighboring projecting manufacturing PCB assembly apparatus electronic black/negative clip to the negative terminal of the battery in the passenger seat (the one with the minus sign).
    Connect the black/negative clip to the negative terminal of the battery. You could also try to connect the negative alligator clip to the chasis ground of the car, this may also work and can cut-down on the risks associated with arching caused by connecting batteries.

    Although Athanasius Kircher claimed the Steganographic mirror as his own invention and wrote not to have read about manufacturing PCB assembly anything like it,[20] it has been suggested that Rembrandt's 1635 painting of "Belshazzar's Feast" depicts a steganographic mirror projection with God's hand writing Hebrew letters on a dusty mirror's surface.[21]

    In 1654 Belgian Jesuit mathematician André Tacquet used Kircher's technique to show the journey from China to Belgium of Italian Jesuit missionary Martino Martini.[22] It is sometimes reported that Martini lectured throughout Europe with a magic lantern which he might have imported from China, but there's no evidence that anything other than Kircher's technique was used.

    Magic lantern[edit]
    Main article: Magic lantern
    By 1659 Dutch scientist Christiaan Huygens had developed the magic lantern, which used a concave mirror to reflect and direct as much of the light of a lamp as possible through a small sheet of glass on which was the image to be projected, and onward into a focusing lens at the front of the apparatus to project the image onto a wall or screen (Huygens apparatus actually used two additional lenses). He did not publish nor publicly demonstrate his invention as he thought it was too frivolous and was ashamed about it.

    For smaller venues projecting apparatus electronic that need a mobile, easy to use projection system, look for a projector that easily connects to your DVD player and sound system amplifier. A model with a remote control will allow you to control the projector from the back of the room.

    Cost: Approximately £1,400

    Portable projection screen
    A lightweight projection screen is a great portable option. Most screens are available in different sizes, so you can select the best match for your venue and audience size.
    Cost: Approximately £80

    Blu-ray and DVD player
    You don’t need an expensive player; just pick one with easy to use functions for both DVD and Blu-ray playback. Check yours has an HDMI port so that you can connect it to your projector with the minimum fuss.

    While larger churches manufacturing PCB assembly already have expensive lyrics projection software and equipment, smaller and mobile churches can benefit from lyrics projection in OnSong. For instance, your small group or house church may use OnSong to lead worship and display lyrics on an HDTV.

    Music therapists have been using lyrics projection to help their clients sing again. Whether it's to bring people into worship, or to help people heal from disease, lyrics projection is a powerful tool that lets you control lyrics while playing live.

    Teaching notes

    This is probably the most important part of this website. If you ever want to view a solar eclipse—whether it’s total, annular, or partial—the first thing you must know is this:

    Never view the Sun with the naked eye or by looking through optical devices such as binoculars or telescopes!

    This is critical! Why? You may have taken a magnifying glass out into the sun and burned leaves with it. If so, you’ll remember that when sunlight is focused onto a small spot with a lens, it gets hot enough to start a fire. So understand this: you have a lens just like that in your eye. If you look at the Sun, your eye’s lens will concentrate the Sun's light and focus it onto a very small spot on the back manufacturing PCB assembly projecting apparatus electronic of your eye, on the retina. This literally burns your eye, causing permanent eye damage or blindness. In additional, there are no pain sensors inside your eye—so you won't even know it's happening!

    If you are now completely terrified about looking at the Sun, good!—you may keep reading. If not, go back and re-ead the warning above.

    During a total solar eclipse, there are a few short moments when it’s safe to look directly at the Sun. This is the ONLY time: when the moon completely blocks the face of the Sun. Called totality, it lasts from a few seconds to a few minutes. The instant the moon begins to move off the Sun's face, you must go back to using safe viewing techniques.

    The above video, “How to Build projecting apparatus electronic a Sun Viewer,” shows you a safe way to watch eclipses or other solar events by projecting the Sun’s image.

    How to Make a Pinhole Projector

    There are safe ways to view the sun. The simplest requires only a long box (at least six feet long), a piece of aluminum foil, a pin, and a sheet of white paper.

    The length of the box is important: the longer the box, the bigger your image of the sun will be. To estimate how big the image will be, multiply the length of the box by 0.01. For example, if your box is six feet (72 inches) long, your solar image will be 72 x 0.01 = 0.72 inches in diameter, or about ¾ inch.



    1. Find or make a long box or tube. If you can't find a long tube, you can tape together two or more shorter ones. (Two triangular shipping tubes, taped together, make a good solar viewer.) Cut out the cardboard at one end of each tube and tape those ends together projecting apparatus electronic with duct tape, so that light can travel the length of the tube.

    2. Cut a one-inch hole in the center of one end of the box. Tape a piece of foil over the hole, then poke a small hole in the foil with a pin.

    3. At the other end of the tube, cut a good-sized viewing hole in the side of the box. Put a piece of white paper at the end of the box, right inside the viewing hole. This is the screen where your projecting apparatus electronic projected Sun will appear.

    1 You many want to let students use a coarse grating for themselves, before they are shown this demonstration.

    Talk students through the observation. Students look at the white-hot filament of a lamp with a grating held close to the eye. They should see a central white line where waves of all colours go straight through the grating. Out to each side, they should see a bright band, where light arrives from adjacent slits with one wavelength path difference. Since the light is white, each bright fringe is spread into a wide spectrum.

    3 Help students to make the link between colour and wavelength. Finer gratings will spread the light more.

    For a diffraction grating d sin A = n (wavelength), where A = angle at projecting apparatus electronic which the light appears, n is the diffraction order (1,2, ...), = wavelength, d = spacing between slits.

    4 For an image of the fringes produced, manufacturing PCB assembly see the web link below. Thanks to Jay Jamaican for suggesting that we add this link.

    Configuration
    You can configure lyrics projection using the External Video Menu. From there you can set up different modes, as well as background colors, images, or even motion videos. There are also other options and settings located in Settings � Live Settings � External Video � Lyrics Projection.

    Hands-Free Operation
    Once you've connected a video device (HDTV, projector, etc.) to the device running OnSong, you can tap on the sections manufacturing of lyrics you want to display on the external video device. Another method manufacturing PCB assembly is to use the hands-free features projecting apparatus electronic of OnSong to control lyrics as well.

    Arrange your songs from the top down using Flow and then use Autoscroll to have the song scroll from the top to the bottom over a certain amount of time. This will also select the sections as they come into view and display lyrics!

    For even more control, projecting apparatus electronic use foot pedals. If you are using foot pedals in addition to lyrics projection, OnSong will scroll the song by jumping from section to section. If you are using other pedal models, you can set up OnSong to scroll by section in the Foot Pedal Settings Menu found in the Foot Pedal Setup Screen.

    Cost: Approximately £50

    Amplifier and speaker system
    All you need for your sound system is an amplifier and a set of speakers. For a smaller venue, choose one of the simpler amps to use with two-way speakers, which will give good sound quality in a simple portable package.
