Steampunk desk lamp

thingiverse

I designed this desk lamp using Onshape CAD software and printed it with my Ender 3 FDM Printer. Assembling is done using 31 M4x16mm and one M4x25mm cylinder screws. For the steampunk effect I painted it with Iron Rust Paint and finally I installed a 5V LED strip. Additionally I used an Arduino Nano for the fade effects using a BC337 NPN transistor and a 10kOhm resistor, some (very few) soldering skills are needed then. The lamp consists of 10 parts, each part has to be printed once. No support is needed. I used a 0.35mm Nozzle and a Layer height of 0.16mm. No rotation or positioning of parts is needed for printing. Cable keying and attachment of the Arduino board is done using a small bracket which can be omitted if you don’t need it. For painting I used a iron rust effect set of ochre brown color, painting was done after assembling the lamp. I used a 5V self-adhesive LED strip of warm-white color for the lighting, it can be cut to fit well into the lamp. My LEDs draw around 100mA of current with a 5V USB power adapter. Optional lighting effects like shown in the video: You will need a NPN transistor like the BC337 since the Arduino pins can only source a few mA of current. The circuit is pretty simple as you can see in the circuit diagram you find above. The Arduino sketches can be uploaded to the microcontroller board using the arduino software. „fade.ino“ uses a sine table to obtain smooth fading on and off, „flicker.ino“ just uses a random delay where the LEDs are on with random brightness, and „flourescent.ino“ imitates the behaviour of an old flourescent lamp which flickers every 20-30s. https://www.youtube.com/watch?v=DSmo3u_l5Xo
