Large scale LED controller for boat
I sure could use some help on this project, also would be willing to pay for high quality professional services. (must prove you are qualified)
Here's the project: We have 50 - 20ma high output LED's that will be installed in the boat transom, approx. 2" spacing. Need to have these led's scroll, chase, dim. Power supply is 12v (not 24v)
Where do I start? I'm not an electrical engineer, I am a test engineer stuck with this project for a show boat to be displayed at an annual convention.

You can buy 50' LED rope light with 8 function controller for <$50, see ebay. May require dropping the 12V down to whatever the unit uses.

No rope light stuff for this boat! These are high output stainless led designed for marine environment were using. Were looking for a high end custom install, not a store bought, off the shelf screw on or glue on. Thanks though.

Well, if you want to make it yourself and have flexibility in the patterns and timing, you will likely want to use a microcontroller and drive the LEDs using multiplexing.
For a standard multiplex, there will be 15 wires that you will have to route to the LEDs. If you would like to elaborate on what you require, including customisation features, I can design or at least help you design a unit.

Well, what do you require?
* Individual control of brightness for each LED?
* User programmable patterns?
* Pattern-change triggered by external input? (or just internally timed?)

User progamable...dimming all, screoll, sequence, etc.
If the guys like the transom, then they want me to do the sides, which will be 125 LED's per side.

How will you find someone to come install if you haven't specified a location!

Well he said he was a test engineer and his people had given him this project. It would be logical to assume that he can do the electrical install itself but wants someone else to do the microcontroller module design.
