What REALLY seems to be going on here is that everything was already made... 2-3 years ago, and the crowd-funding is all a publicity-making machine. Seems like it is all done...
If that is the case then why don't they have real final units to show the media. At least one report from a journalist I've spoken to said the prototype failed in two devices he tried, and they struck it up to being a prototype issue that will be sorted out in production.
Also, if it's already finished, why isn't there any technical data released at all?
I am not surprised that the prototype failed in the device that he tried in. Here are some measurement that I made on my boost converter circuit based on the LTC3539 chip.
First I measured the current consumption of a Fuji Camera, I am not sure of the model, but at least five years old, it use and XD card.
Here is the current consumption while taken a picture with the flash on. The current is 200mA measured with a Tektronix TCP202 dc current probe:
Same setup without using the flash:
And the current drawn during start up:
If I zoom into the peak, I see this:
The batteriser needs to be able supply about 1A of peak current if used in this camera.
So now I know what the peak current looks like I can use an electronic load.
This picture shows the battery terminal (input), blue trace, using the boost circuit:
Without the boost circuit, the battery terminal voltage looks like this:
The battery voltage drop less without the boost circuit than with.
Note: Some the components I am using are too big to fit in the batteriser clip.
FAILfor high current devices like digital cameras.
