When the iPhone’s initial specs were released by Apple, tons of users complained about its lack of a camera flash. Using a USB connector, 4 white LED’s, and a tact switch, I built a removable flash unit.
More after the jump.
The LED’s are ~8000mcd 3mm white LEDs (T3 IIRC). You can get a set of 50 from ebay for less than $20. I had a bunch of them sitting around the house when I was struck with this idea.
The connector is from a broken car charger. I was afraid that the car charger’s connector would only include pins for the + and - points on the iPod, and I was right. Luckily I was able to pull the pin in the + position out and stick it in the 3.3V out spot.
You turn the flash on by holding a small tact switch I installed in the hole where the cord used to be. Just hold down on the button and snap your picture - it’s that simple.
And of course some before/after shots from the iPhone’s camera itself:
Of course, in a completely dark room, it lights up beautifully. Here’s my hall closet, which was originally solid black:
I posted a brief how-to over at the forums, enjoy
