8000 ibertren coaches series lights
Version 2.0
After the first home made lighing project for the ibertren coaches series 8000 i decided to fnd an easyer, more precisier and professional solution. That's why i started to learn to use some CAD circuits software. and after a some project ideas this is the fist definitive final solution:
Afeter that i started to look for a place to print the citcuit drawn before after a month my 1st prototipe arrived home!!!
This design is optimised for Digital circuits and is made specifically to consume less power possible; lights turn up a 12v and with the electrolitic capacitor they can stay on for a sencnd in case of a lack of electrical contact. The capacitor is placed in the 1st passengers compartment; that's a good soution that allow to lock the light system to the internal compartaments structure.
After the 1st circuit draw i tried to find more elegant alternative solutions, the best idea i had was to change the electrolytic capacitor with a tanatalium one; they are squared small and have high capacyty, thanks to their shape they can be placed on top of the circuits hided from sight throw coach windows. Of this kind of circuits i realized 3 different types one with a maximum of 3 capacitor and another one with a maximum of 6 capacitors .
A small change has been done even in the bottom part: i have eliminated the two copper plates under the train prefering leaving the electric wire directly fixed to the screws, leaving the power supply almost invisible
A small change has been done to optimaze lights for trains that operate only in analog circuits: i put 4 couples of leds in parallel way to allow them to switch on at 6V. This solution however consume more or les the double of the digital version. Above the 2 schemes: 1st with Tanatalium capacitors and the send one with electrolithic capacitor.
