So yeah , to be able to use this custom unit , there is alot of conditions xD
Cost saving and simple.
This LED I'm making is based to the firefly (an insect with a light up buttock xD )
Simply made from LED bulb , Battery , thread and a small piece of pla-plate.
in this case , I made mine using a blue L.E.D i obtained from a old toy , and 1 x CR1220 flat battery. (you can use different size items as you prefer)
The pla-plate acts as a push and pull mechanisms that enable and disable the circuit... when pushed in , it will disconnect the LED leg from the battery that disconnects the circuit , , and when you pull it , the circuit will be connected as the LED leg touches the battery ....
The thread will maintain the position of the LED legs and the battery~
Well , this isn't a pro way to make a L.E.D unit , but you can make this using items you can get from stores at low price ~ PLEASE be very patience when setting the LeD unit xD
heheh so its working , then its ready to be set up in my Gunpla xD
Fabulous ~ xD bright enough to light up the top camera :D
Comparing , the original L.E.D unit and the Firefly unit ....
Both using the same battery , CR1220 , but different bulb size ~ the blue one appears brighter and more beautiful xD
I hope i am able to shared this to help you gain knowledge and get some idea to custom or enhance your Gunpla xD
