Try your hand at soldering or brush up on your soldering skills with this beginner-friendly lighthouse soldering kit! The PCB comes in 2 parts: the main PCB, where you solder the 11 components; and the base PCB, which slots into the bottom of the light house and (with a couple of blobs of solder) gives your lighthouse a strong and stable stand. Once soldered, this kit will emulate an Isophase lighthouse - but fear not all you lovers of Occulting lighthouses! By changing the value of the resistors you can change the flashing pattern. Please note: Battery not included What you will need: A soldering Iron Solder Flush cutters Eye protection, flying legs can hurt! 1 x CR2032 Battery Kit contains: 1 x 220 ohm resistor ( Red, Red, Black) 1 x 82k ohm resistor (Grey, Red, Orange) 2 x 220k ohm resistors (Red, Red, Yellow) 2 x 2N3904 NPN Transistors 1 x Power switch 1 x CR2032 battery holder (battery not included) 2 x 10uF Capacitors 1 x Lighthouse PCB 1 x Stand PCB 1 x White LED Documentation: Step by Step guide Want to know how this works?
