Since there was excess material in the production of LED parts for cars, I tried dressing up my own personal computer as a glowing personal computer.
We made some scratches on transparent acrylic sticks, which are also used for optical fibers and Christmas trees, so that the entire acrylic stick shines with two LED bulbs.
Attention should be paid to the fact that even if the number of scratches is too large or too small, the light does not reach the whole and some parts are not lit.I think it started to glow relatively nicely.
Since 12V electricity flows to the power supply of the PC, any parts for automobiles can be used for the PC.
However, it is necessary to pay attention to parts that require large currents, depending on the capacity of the ATX power supply, which may cause forced shutdown or hardware trouble.
It is a part that was manufactured 10 years ago, but there are products that are currently illuminated as a whole, so if you use them, that may be recommended.
