Iron - a light gun for the Speccy.
IRON (C) L.D.E. SOFT Today I, L.D.E. soft, prepared for you another article from interesting shemkoy for Spectrum, which is called "Light pistol. " This is not my own development, but only a split secret and little-known wide circle circuit is very interesting gadgets for our beloved Spectrum. But I also spent Coy are the mental and material costs to you were able to calmly collect myself on this device prepared by my description. I also give the address of the manufacturer's light gun, this is for those who do not hold soldering iron in his hands. Maybe it will even be a kind of advertisement for this firm ... This lotion I found on sale at the old radio market, the year of commercials in 1994 ... Then this pistol worth 40,000 tons RUB! Agree sum in those days considerable. Well, okay, most importantly, worked normally and toys on this thanks. The gun make even a floppy disk with 4 (at the time) games, adapted for a light gun. Connect the gun to your computer is using an interface KEMPSTON joystick moreover, the design is thought to use virtually any type of interface (which I highly approve of). But this miracle of technology suddenly disappeared from our Mitinskoe radio market and many of Moscow's (and other) were sinkliristy without this device. In addition, in the company description for the device was not given full electronic circuits, and all marked with chips and parts were simply erased. But I decided to repeat the scheme of the gun and tell it to all who wish to have around this lotion. After work, I have been successfully fabricated several of these pistols and everything works fine. And play with this gun is much more interesting than similar in principle to all known video deck Dandy. The fact that the Spectrum-precise targeting to hit almost reaches up to + / - 1 pixel screen, and therefore need to aim all the rules, with foresight. And the so-called Dandy, 100 points out of 100 can beat a blind man (this is not a joke). Therefore, a pistol on the Spectrum much cooler! We now turn to the scheme: R10 VT3 +9 in VD1 C1 R6> R1 R3 R4 VT1 R9 C5 VT2 R8 8 ■ 10 9 R2 C3 R7 1 ■ 3 R5 February 1912 ■ May 11 ■ 4-C6 June 13 R12 D1.1 C4> D1.4 D1.2 Exit List of radio:> R1-1.2mOm R4-7.5kOm R7-220kOm R10-2.2mOm Total R2-100kOm R5-7.5kOm R8-2.2mOm R11-7.5kOm R3-1.2kOm R6-120 Om R9-2.2mOm R12-120 Om C1-C4-10mkF 0.15mkF VT1-KT368B VD1-FD256 C2-C5-10mkF 4700pF VT2-KT3107 DD1-K176LA7 (K561LA7) C3-22n C6-33n VT3-KT3107 powered battery "Krona" Now some of the technical data received from the accompanying description: Power supply - battery "Krona" 9B (located in the handle pistol). Shooting range - from 0.2 to 4 m. Output - open collector. Rate - up to 5 shots per second. The required brightness screen for confident shooting from a distance of 2 m - not less than 100 nits. Accuracy is at a distance 2m when using a TV with a diagonal of 51 cm + / - 1cm. Connect the gun to various kinds of Kempston joystick: Connecting effected by means of four wires of different Color: Green - 1-th output trigger buttons White - 2-th output trigger buttons red - the output data Blue - 9 in the charts Option: I - joystick with the closure of the buttons on the negative (common) --- Green Left Red --- Right White ----- common Blue ----- common Version: II - joystick with the closure of the buttons on the plus 5c. (Num) --- Green Left Blue ----- right White ----- common red --- total Certainly it is possible to reduce the number of wires coming up to 3, but will lose the ability to use various types of joysticks. Structurally, the scheme is going to a small shawl, which is placed inside the gun. It is desirable to screen the board and mounting bracket parts of tin, which is connected to the negative power supply circuits. Receiving the LED is placed directly on the board, as in the case is battery power, "Krohn." In corporate performance used a gun from the game "videosport, with optical lens in the barrel of the gun. But the body can be glued together, and himself, setting the trunk of any converging lens of suitable size for distance of 70-100 mm from the photodiode. If the scheme is properly collected from the healthy parts, the adjustment is only in the selection of the distance lens to the photodiode and install the latest focus of a lens. Well, sort of, and all I can to help you. And now address the manufacturer: TOO novine, 195299, St.Petersburg, POBox 87. Denis (L. D. E. SOFT) 400-0436
