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:

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
