Need someone to build a fairly simple LED lighting controller.

Hello,

I am looking for someone to help me with a basic stamp application
and was wondering if someone on the list can assist me.

We are an architectural model shop and are building a large
architectural model with lighting. The lighting is going to be White
LED modified with JKL white caps to make it look more incandescent.
We are using Advance Transformer's Xitaniaum's DC/DC current
controllers so we can add LED's in series and not worry about the
load etc.

Now I need a controller to manage the 5 lighting circuits with a
timed program. The idea is that 5 circuits come on in a sequence and
then go off in a sequence so that the building does not light up all
at once and look like a lantern. The user can start this sequence
with a single switch.

The program outline is farily simple, something like

Switch 1 on starts timed sequence
Output 1 goes high for 5 min
wait 15 seconds
Output 2 goes high for 4 min
wait 10 seconds
Output 3 goes high for 4.5 min
wait 10 seconds
Output 4 goes high for 4 min
wait 20 seconds
Output 5 goes high 20 seconds

If Switch 2 on then start program again after 1 minute

.

Other options.
Jumper or internal switch would light all lights for installation
and troubleshooting.
All time delays would be variable so that we can tweak the program
(with a laptop, downloading a new program) in the field when we
install.
I would like to look at the possiblity of adding a simple light
sensor so that the model would start automatically at dark.

The DC/DC controller is 24V input and 5V output so we can easilly
switch these with a relay (lag is not important)

I was hoping that someone could either write the code and advise or
preferably buy the hardware (not the LED stuff, just the stamp,
relays etc., get it working and ship back to us.

Lead time is one month. Contract is approved so this is something we
definately need.

Feel free to forward this if you know someone who might be
interested. Call 800 448 8808 or contact me off the list at
cwho@l...

    check out this web site for hardware that would work in your application.
