Dang... looks like I got into the second batch. Shipping on the 18th

Lol weird. Wasn't there that type of on board eprom or something that you could only clear with a UV light ? I wonder if it's something similar.

Xenon flash bulbs also produce an Electrical Pulse because of an arc needed to create a flash. I noticed how close he held the camera to the Pi and now I have to wonder if it would crash if the xenon flash was held further away from the Pi.

External triggering is the most common method of operation, especially for photographic use. The electrodes are charged to a voltage high enough to respond to triggering, but below the lamp's self-flash threshold. An extremely high voltage pulse, (usually between 2000 and 150,000 volts), the "trigger pulse", is applied either directly to or very near the glass envelope.

Seems the SMPS IC is photosensitive:

IC that now.

needs a glob put on the chip

Covering the entire package with a glob-top material, such as Namics Chipcoat G8345-6, provides the best light blocking. When using a glob-top material, it is important to use sufficient material to completely cover the corners of the package

On the RPi thread, people were just suggesting to put blue sticky-tack on the IC . Or to just flip it the other way around.

Re: The What You've just Bought thread!

Does anybody know how that blue tack will affect the chip/board over a period of time and hot/cold temps? That stuff would most likely work fine, but technically it's not designed for IC chips and boards. The glob is made for covering IC chips

I'm sure they were just using it temporarily - at least I hope, anyway.

Who knows? That glob stuff might cost more than the Pi
