I'm no god member, but have to agree with them....
I expected an arduino based camera, which would be amazing due to the difficulty of making such a thing, but... I suppose I should've expected it.. it is a camera of which the arduino controls the on/off switch.
The number of views a topic receives isn't a reliable means of expressing the popularity of the topic. I myself would've named the topic allong the lines of 'arduino controlled spycam'.
That said, why this topic receives (so many) negative reactions.. is a bit odd. It is easier, friendlier and overall better for the forum if such posts weren't made. No tips or comments other than 'it doesn't work!' or 'useless' are provided.. so basically, it can be considered flaming / trolling.
But meh, as I've said, I got tricked by the title aswell... and my advice to you, don't feed the trolls.
