That's a cool project.
Disposable cameras are really hard to come by where I live. So I had to buy a "proper" slave flash.
But I would've loved to build my own flash. I built a C shaped flash bracket though, I'll post some pics soon.

Unfortunately I can't read the text, but be careful of the sync voltage of those disposable camera flashes.  The ones I have are over 100v so it makes it harder to trigger.   I think a lot of people use a SCR or optoisolator to separate the high sync voltage from the camera. 

I am very curious about how you trigger it, I guess you turn on the USB power + flash at the same time and you didn't use a optical slave trigger
