Christmas illumination using breadboards

Just a thing I quickly made a short while ago. There’s nothing special going on. The board on the left has one resistor per LED, on the board on the right, two LEDs and one resistor are each wired as a series circuit.

Note: I don’t leave this running unattended — I’m reasonably sure the entire thing would fall to the floor in a medium~major earthquake and the risk of causing a short is relatively high. Not that the short would necessarily cause a fire, but better safe than sorry.

Merry Christmas
