Today, I was thinking about how I can turn a household bulb into a party light by connecting an embedded computer for my next party in my garage.

We will use a SSR (solid state relay) relays to enable common AC household light…

Where do you buy your SSRs? I've been looking into doing this with Christmas lights, but haven't found out where to get them.

You can get the SSR4 boards from cubloc.com,
I think to get actualy SSRs, you can get them anywhere such as mouser.com,
digikey.com, etc...etc...

Interesting project, definately quick. The cycling compact flourescent will kill the ballast on the bulb pretty fast. A CF is always a good energy saver, but for on off, LED or incandescent would be a better option.

Futurelec is a good source of medium-quality SSRs. For inductive (usu. motors) loads, put a quencharc across the load. One can make his own SSRs if he needs many. A good place to start would be a perusal of a MOC 3010 optocoupler data sheet and applicaton note. If one chooses to use a high-current incandescent such as a halogen bulb, consider a plastic inrush surge limiter, in series, these don't have a linear R w/ temp.

Now add a couple of servo motors to the base, make a few more, add a color shade or two and you've got some serious party equipment.

On a safety note, this device should be enclosed in an earthed metal box equiped with a fuse. On the bench, open as it is shown, it should only be used through an isolation transformer.
