This flicker lamp was created using a 3D printer and some hand wired circuitry. I modified the original print file to include a base that holds the batter and circuit board for the flickering LEDs. Then I drilled a hole between the base and globe portions using a step bit so that three LEDs could be hoisted into the globe. Each flickering LED is in series with a 330ohm resistor, and all three are power by one 9v battery. The LEDs are soldered to different lengths of solid wire to hold them aloft. I did not account for the cap that connects the 9v battery to the circuit board but luckily it fit just right with the cap on. Not a lot of engineering went into this build, mostly measuring the circuit board and battery to add the correct size base to fit everything.
