Hahaa, I have the mobile arcade version of that kit! Funny thing is that it still has the kitchen and lantern parts.

Hi Jkiker, you can snip the leads on both the LEDs and the resistors pretty much as short as you want, good call on using the mini copper jaws as a heat sink to draw the excess away from the diode as for your second question, I generally wrap the wire around the resistor/ LED leads, or wrap the resi...

This fellow here does some pretty innovative stuff with lighting and (pic)microprocessesors, he has a spot where he heas a primer on LEDs and running basic circuits. He also uses current blocking diodes in place of/ in conjunction with resistors, pretty clever. http://dorobou.blog.so-net.ne.jp/ You ...

Something I've been noticing from our Japanese brethren

I was looking at a fellow's lighting setup for his 2199 Yamato and he has diodes in line with his LEDs. Why is that? LEDs themselves are diodes and will work in only one "direction" so why bother with an extra diode? I've noticed this same thing from a few different builders in Japan too b...

I started to film my build of the 1:500 Space Battleship Yamato, I got through most of the main lighting and was just about to get into the Madman lighting kit when my responsibilities in the RCN took me back out to sea. If you look for John Beaulieu in Youtube you will find my build quickly enough.

I did that for my Stargazer Serenity build. Swapped the amber and yellow LEDs for white ones and tinted them blue.

By the way, the boards will handle 9 volts with no problems, just change out the LEDs first. :wink:

another thing you can do is just get white LEDs and tint them with clear red/green/blue ect.. that way you can save the headache of working with different voltages.

also, this site has a handy calculator to help with figuring out resistor values

Ok, I have a two string of LEDs, two LEDs in series per string. My source is 9 VDC. Being lazy, I punched the numbers into an online resistance calculator, which gave me 150 Ohms. No problem.
