You guys are bringing everyone down.
No, just being practical. Ideas on their own are actually worthless, and that's a well proven fact in most cases.
The OP asked if it was possible to sell his idea, the answer is almost certainly no, without even knowing what it is.
You can have great ideas and make lots of money with electronic designs, but not usually in mass market products.
Sure, no one would deny that.
BTW, the OP has actually told me what the idea is privately (I guess he thinks I'm trustworthy
), and well, I don't think anyone is about to go out and steal it and get rich. As predicted, IMO:
a) it's not really original, very simple and obvious (for those with the need), and the solution can be hacked together with off-the-shelf modules already.
b) it has very limited niche appeal
c) it has the usual problems with the actual physical implementation of it, and big differences in any sort of consumer installation and need.
It's more like something you'd see on Hack-A-Day, and you'd get more excited about that he used a toaster oven to solder the boards or whatever, than about the actual idea.
Sorry, just being honest.
Dave.
