generator rewinding (updated) FIRST WINDING for light it must be wound evenly, since the volume of the wire that can fit into the coil and the convenience of winding each subsequent layer of wire depend on the evenness of the winding you need to decide what kind of light will be used - a 12-volt halogen bulb or an LED old tungsten filament lamps are not considered, because the amount of light they have = 15 lumens per 1 watt of energy, this is too dim if you want to keep the retro style - buy a 12-volt halogen bulb instead of this one the light of a halogen incandescent lamp is bright yellow, almost white the most natural of all electric lamps, except for xenon it is perceived easily and does not strain the eyes, you can clearly see the brightness of such a bulb = 25 lumens per 1 watt of energy these are hot bulbs, they heat up to 400 ° C they can be bought in a case with or without a reflector buy more ceramic base, which is attached to the headlight with bolts, you can use a motorcycle headlight with an existing halogen lamp, the LED light is bright (that is, economical, with the same power) = 100 lumens per 1 watt of energy, you can choose pure white or yellow-white (warm white), this light can tire the eyes, because its spectrum consists only of ultraviolet light, which is passed through a yellow phosphor, a deceptive white color is obtained, not real, but visible as white, in the spectrum of such light there is only yellow and ultraviolet, and there is no red, orange, green, blue, blue, violet, therefore the eyes never get used to such unnatural light, the LED cannot be overheated above 45 ° C, so it must be mounted in a thick aluminum case that will have time to cool in the air, for a three-volt LED, you need to wind 150 turns of wire 0.8 mm thick. Three full layers = 150 turns or a little more. If the wire is thinner, then more turns will fit, for example 160 It will not be worse, the main thing is to fill each layer with wire from edge to edge evenly, as I do in the video If the wire is thicker than 0.9 mm, then it will be less than 140 turns and the voltage will not be enough for the LED to glow, because it needs at least 3.3 volts It is advisable to use a single-crystal three-volt LED with a power of 10 watts, for example XML-T6 You can also use a three-watt one in a plastic case like peas, but not an assembly of a large number of small LEDs, since they constantly burn out due to improper selection of resistors or without them at all In addition, they have bad lenses that do not shine far It is not recommended to install 1-watt LEDs, since the generator will still burn them out, because it will be included without a current limiter directly into the generator for a 12-volt halogen lamp, select a wire of 0.4 ... 0.5 mm 400-500 turns quantity turns depends on the thickness of the wire, there should be 4 full layers SECOND WINDING for controlling the thyristor 250 turns of 0.2 mm wire or the same thin as the third winding, but carefully, so as not to break such a thin wire at the terminals. Again, you can also use 300 turns, it won't be worse, wind a full layer or 2 full layers THIRD WINDING for charging the capacitor, that is, for a spark from 3000 turns to 6000 turns with a wire of 0.1 mm ... 0.2 mm, the greater the number of turns, the higher the voltage, which will give a better spark, but 3000 turns are enough for a good spark, if you took a wire of 0.2 mm, adding an external high-voltage coil, preferably 12-volt, you can use a 6-volt thyristor, better than BT152, you can use the Soviet KU-202 and other thyristors or triacs, you can wind a little in bulk, but try to wind evenly, insulation through 3-4 layers, paper tape
