Specification Brand : HPYNPES BulletPoint1 : Function introduction: When the top is rotated, the vibration switch is turned on due to the centrifugal force, and the light-emitting diode emits light. Due to the persistence of vision in the human eye, it seems that the LED emits a segment of linear light effect. BulletPoint2 : Working voltage: DC5V, PCB dimensions: 65mm*55mm BulletPoint3 : Designed for Beginners:Special design for electronics starter to learn to solder electronics components. Soldering project kit will improve your electronic knowledge and soldering skills in practice BulletPoint4 : Easy to Assemble: Electronic DIY kits uses safety materials, effectively avoid corrosion and wear out. Components’ names have been marked on the PCB board and the circuit design is simple. Even beginners can easily solder successfully BulletPoint5 : Warm Reminder :DIY electronic components kit requires buyer to assemble and welding, If you don't have any soldering experience, please read the soldering instructions and use soldering tools carefully to avoid safety problem CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier1 : 0768443667692 ExternallyAssignedProductIdentifier2 : 768443667692 ExternallyAssignedProductIdentifier3 : 00768249060543 Hazmat1 : LITHIUM METAL BATTERIES PACKED WITH EQUIPMENT Hazmat10 : CN_SmallLithiumMetalBatteryWithEquipment Hazmat11 : DE_SmallLithiumMetalBatteryWithEquipment Hazmat12 : EG_SmallLithiumMetalBatteryWithEquipment Hazmat13 : ES_SmallLithiumMetalBatteryWithEquipment Hazmat14 : FR_SmallLithiumMetalBatteryWithEquipment Hazmat15 : GB_SmallLithiumMetalBatteryWithEquipment Hazmat16 : IN_SmallLithiumMetalBatteryWithEquipment Hazmat17 : IT_SmallLithiumMetalBatteryWithEquipment Hazmat18 : JP_SmallLithiumMetalBatteryWithEquipment Hazmat19 : MX_SmallLithiumMetalBatteryWithEquipment Hazmat2 : UN3091 Hazmat20 : NL_SmallLithiumMetalBatteryWithEquipment Hazmat21 : PL_SmallLithiumMetalBatteryWithEquipment Hazmat22 : SA_SmallLithiumMetalBatteryWithEquipment Hazmat23 : SE_SmallLithiumMetalBatteryWithEquipment Hazmat24 : SG_SmallLithiumMetalBatteryWithEquipment Hazmat25 : TR_SmallLithiumMetalBatteryWithEquipment Hazmat26 : US_SmallLithiumMetalBatteryWithEquipment Hazmat27 : ZA_SmallLithiumMetalBatteryWithEquipment Hazmat3 : II Hazmat4 : 9 Hazmat5 : AE_SmallLithiumMetalBatteryWithEquipment Hazmat6 : AU_SmallLithiumMetalBatteryWithEquipment Hazmat7 : BE_SmallLithiumMetalBatteryWithEquipment Hazmat8 : BR_SmallLithiumMetalBatteryWithEquipment Hazmat9 : CA_SmallLithiumMetalBatteryWithEquipment HeatingElementType : Ceramic IncludedComponents : PCB board, LEDs, Vibration Switch, Battery, Wire, User Manual ItemName : DIY Practical Soldering Practice Kit Practice Learning Electronics Training Board ItemPackageDimensions_Height : 7.2898 centimeters ItemPackageDimensions_Length : 1.397 centimeters ItemPackageDimensions_Width : 6.096 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : soldering-stations Manufacturer : HPYNPES Material : copper ModelNumber : A NumberOfItems : 1 PartNumber : SonewZP29975 PowerSourceType : Battery Powered ProductDescription : How it works When the battery is installed, the vibration switch S1 is disconnected, so the circuit does not work. When the gyro is rotated, due to the centrifugal force, the vibration switch S1 is turned on, and the circuit works. The working principle of the multivibrator circuit is that when the power is turned on, the two transistors Q1 and Q2 will compete to be turned on first, but due to the difference of components, only one of the transistors will be turned on first. Then the two triodes in the circuit will take turns and cut off, and the two light-emitting diodes will continue to circulate and emit light. When the top is rotated, the bright LED will appear a straight line effect. Since the lights are staggered and every two lights are alternately lit, there will be multiple dotted patterns.
