I wish I could do those Micro LeD's but I am afraid that my big old Gorilla fingers might get in the way. I am wondering if the tiny black squares between the upper and lower lights is a Resistor? What I find amazing is that the headlights and taillights switch when changing the trains directions. Maybe the only way to try is to do it.
Yeah those black squares are surface resistors. This type that usually get soldered flat onto boards by machines have generally replaced the old style color banded raised ones. They are really tricky to solder by hand.
I would also be nervous about drilling through the face of my train. I think these E231 series are a dime a dozen in Japan. Rarely see the metro trains for sale on eBay over here except for some new ones from Japanese sellers which are at least AU$40+.
Interesting to know about those tiny resistors. I don't have any qualms about customizing any train but but for the most part they are used ones from Japan.
