A LED lantern made from a matchbox. More than easy soldering project where the object is a lantern hanging on two matches. It’s fed by some copper wire and a button battery.
2x neodymium magnet 2mm
3mm RGB slow flash LED, 3v
cr2032 3v button battery
an (empty) matchbox, 2 matches
and of course a soldering iron with some solder, and other tools….
The copper tape conducts electricity from the battery to the LED. The battery has a positive and a negative side. Often the positive side is marked with a ‘+’ sign. The LED also has a positive leg (long) and negative leg (short). Two matches are used as poles. The battery is locked in between two neodymium magnets and some copper tape, so you can replace the battery when needed.
