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
