Sorry, but please allow me to hijacjk this thread. Think it's a good thread for people who wants to makes their toys looks cooler.
Not my macross toys, but my 2 MG Griffon. I fitted a LED into their head:
They definitely looks better then before.
I'm using a 12V DC power supply, coz my display cabinet also uses this voltage. So I only need 1 switch to turn on/off all the lights. As a LED only needs about 3V, I connected it in such a way that there's 3 LED connected in series with a 100 ohm resistor. Hard to go into details, but that's approximately how it's done.
Next, perhaps I'll try to see if I can add in LED to my VF-1S.
