When your cubicle desk looks like everyone else’s, you’ll do anything you can to differentiate your space. And if you’re looking for a unique way to bring a little festive cheer to your 9 to 5 drudgery, check out this adorable and minimalist 9V-powered LED tree by Redditor ‘jingle_balls123’.
For those of us who don’t know the first thing about wiring up such a creation, other Redditors have even chipped in to help with instructions on how to build your own:
If using a 9V battery, you’ll need to connect 6 LEDs (in this example: forward V = 1.5V) in series such that 1.5V*6=9V. This will change depending on the forward voltage of your LED. Next, you choose a resistor that will cause the forward current of your diodes to equal the current flow of the circuit. The link I provided pre-edit will help you design your LED array depending on your battery, # of diodes, and diode parameters.
