Purple looks good on green, doesn't it?
I'm an avid listener to The Amp Hour and they interviewed the guy behind OSH Park. @Laen was a heck of an interview, and made me want to try out his service. But my circuit drawing skills are, well we'll say, lacking.
I also hang out on IRC, and one day, in #electronics, someone posted a link to this: http://oshpark.com/shared_projects/s4fzpaFO I needed it. It was just to clever not to have a copy of my own. A few minutes later, I had an OSH Park account, and had ordered copies of the board.
The circuit is really simple, and easy to follow. It's a bunch of leds, a bridge rectifier, a big cap, a couple of current limiting resistors, and a resistor to make sure the cap discharges. I could guess at the design values... and had already decided on what I was going to use, but, I thought it might be a good idea to contact the designer.
The designer of the board, is a seemingly prolific electronic artist, who turns out some really neat LED projects. His site is: http://www.theledart.com/blog/ Aki was a big surprised when I contacted him, but was happy to help. He sent me a copy of the schematic that he built the circuit from.
A few days later, this showed up at my door:

My friends and I were wondering if I would need to trim the board, turns out that the solid black line is a routed line. Not a bad looking board?
As soon as I had the schematic from Aki, I went and ordered the right parts. But I couldn't resist putting int he parts I had on hand.

You don't really grasp how many solder joints are involved in a 48 led bulb until you need to start trimming the legs off.
I didn't ask Aki how he did the hookups for the light socket, I suppose I should have. Here's what my bulb looked like after getting my contacts in place, and all the LEDs soldered in.
And since I'm silly, I ordered most of the finishing parts from Chinese suppliers.. it was another week before I could finish the board. Here's the final product:
Oh, and I did a little video of the project too:
