Intro: Infinite Filament Cube

12 led filaments and half mirror to build a infinite filament cube

Step 1: What Is Led Filament?

https://en.wikipedia.org/wiki/LED_filament

If you want to buy them on ebay, you can try to search the key words led filament chip.

Step 2: Solder the Filament Correctly

Solder the led filaments like the photos. And solder the motor wires to the terminal of the filaments.

Tip: the filaments are really sensitive to the solder iron temperature, you may break it if you solder it too long time or the iron setting is too high temperature.

Step 3: Hang the Filaments Cube Inside the Half Mirror Cube and Glue It.

Step 4: Connect the Filament Cube's Terminal to the DC-DC Boost Circuit.

I use xl6005 boost circuit to convert 5V to 60V for the filaments. Then I can use the USB power bank to power my filament cube. XL6005 can support 5V input instead of 12V input only.

Step 5: Some Other Things I Made With Led Filaments

I finally found them at AliExpress, but only via Google images from "led filament chip" (won't paste the link since it points to the German store and a search inside AliExpress only returns tons of bulbs with filament, but not the pure stuff).
