An ongoing project for creating a high power and speed studio flash (cheaply) that can sync with a chdk enabled camera.
Once I get the new parts (couple weeks ish) I'll make an instructable.
If you don't know what chdk is have a look:

Currently I can take photos at about 1/1000s consistently.
I believe the limitation is the camera.
As the flash timing moves about +-1/4ms
The bulb is being run at about 7.5j, but is capable of about 32j, so I'm going to get a proper sized tank capacitor and use a voltage doubler off the line to charge it faster.
