This week, finally, we learned how to use the laser cutter.
Because acrylic embraces the property that it can transmit light, thus the idea that making a light bulb comes up.
Firstly, I found the image of a light bulb and then put it in the illustrator and to be prepared of laser cutting, I changed the file a little to meet the laser cutter’s requirement. I set the stroke weight of the bulb’s outline to 0.01pt for cutting and filled other parts of the bulb to make sure they were going to be etched.
Afterwards, I used a piece of cardboard to test my setup, and it’s not bad.
So, I tried on a piece of acrylic.
Great, I got a perfect acrylic bulb.
Of course, to light up the bulb, I need LEDs illuminating at the bottom of the bulb. Therefore, I need a container not only to support the bulb but also to hide LEDs.
I measured the thickness of the acrylic and LEDs using the digital caliper, which is super convenient and straightforward. Then cut a block of wood into two pieces and stuck the bulb between them using the wood glue.
Next step, I build the circuit. It’s quite easy, basically, I just used electric wires to connect resistors, LEDs, switch, and batteries.
Next, I stuck LEDs into the gap between two pieces.
To hide the “ugly circuit”, I cut 4 pieces of wood and stuck them together as a box to contain those components.
Finally, I finished!
