hi there!
i have improved my proton pack from the 12" ray figure!
now it has a blue light where the powercelllight is!

Kind of a blurry picture, but it looks like you did a nice job!

here! i did a video on how to do this!

Nice! Is the pack hollow inside or did you have to drill it out?

like i said in the video there is a lot of space inside the pack! all u have to do is cut out the blue coloured area for the led to shine through!

Ah, I watched the video while at work where I don't have speakers. XD

no problem! i watched the video and found out that it could be hard to understand for someone who is not into electronics! so basicly speaking:

just solder the blue led parallel to one of the red leds!
but NOT directly (meaning positive on positive and negative on negative)!!!!!!!!!!!!!!
this “could” influence the chosen red led in speed and/or brightness!!!!!!!!!!!!!!!
do it like i said in the movie! follow the red wire to the circuitboard! there is the main-positive, grap it from there!

here is a pic!

a little hint:
take the chance an colour the clear leds with a red permanent marker for a realist look!
