[QUOTE="Avolow, post: 3571289, member: 50962"] Hi all, So, after a recent de-cluttering of my display cases and crawl space I took a ton of robots from my Transformers collection and sold them at a local vintage toy shop. After prices were negotiated and agreed upon the owner told me he was short on cash and part of it would have to be in trade. That didn't hurt my feelings one bit with this in the shop. :D [IMG]http://www.therpf.com/attachment.php?attachmentid=442402&stc=1[/IMG] When I got home and started looking at the lighting kit online I about had a hart attack. I didn't realize just how much it was going to cost. With that thing going for more than the model does I decided to try and come up with something custom. Looking at different options I realized it was not going to be that easy for me to get some of the effects that I am looking to do, and while I am no stranger to a soldering iron I am not that great with designing electronic circuits. I started looking online for a few pre-made diagrams and found a couple that I like. One of them is a fade in and fade out LED that I would like to use on the some of the NAV lights. I know from reading about the LEDs that I am going to have to recalculate the value of the resistors and maybe the capacitor and transistor for the number and color of the lights. [media=youtube]qLAi7hkDuYw[/media] The next one I found is a random LED flasher that I think I can use in the bussard collectors. This one I may try and find a different flasher that supports either 5 or 10 LEDs, 5 if I do two boards (one in each warp nacelle) or 10 if I just do one board in the secondary hull. [media=youtube]Ep7LGheUBbo[/media] So far they seem very straight forward and something that I can wrap my head around easily enough (I think). I am going to be picking up some double density LED tape that I can cut up and use for general window lighting and maybe a few other places like the original light kit includes. I have even thought about some fiber optic lighting in the shuttle bay if it will all fit in. Now, where I think I am going to need some help is with the bussard collectors. I love the look of both the spinning spokes and the rotating lights. One or the other, but not both. I am also not interested in a noisy model, so the motors are out. I have been looking at the TrekModeler and Trekworks pieces. These are very nice, but just the two bassard light assemblies from one of them are as much as the whole light kit and I am not in a position to be able to spend a lot of money on this kit, so I need to try and replicate the effect on my own. I really like the way they look and I have seen a few videos with them. They do mention that the cameras are not showing them at their best, but I think the look of these are what I am looking for. [media=youtube]gqCLBu0Wk_c[/media] [media=youtube]ZKlvW-5bsfY[/media] [media=youtube]4U93vwYxz1U[/media] I know this one is the new movie version, but the colors could be changed to give the TOS effect. I have found a few similar diagrams on various sites. All of them use the 555 timer and a 4017 IC.

Should I go with diagram A were the sequence would light 1&2, 3&4, 5&6, 7&8, 9&10 in rotation then start over giving it a repeating 5 flash sequence. Or should I go with diagram B were it would light 9 2 9 10, then 3 4 11 12, then 5 6 13 14, then 7 8 15 16, then start over giving it a repeating 4 flash sequence.
