It's an easy way to find out which community is better (you guys win).
And thanks for the answer. I didn't know you could fit an AM radio circuit in something that small.
This came out of a lighter. You would press the button down to generate the spark and it would also makes these LEDs flash. What I don't understand is, how does the piezo sparker activate this circuit from over 1 inch away?
You can press the sparker anywhere along that circuit within a 1.5 inch...
I dropped it and now there is no LED indicator light lighting up. And it will not show up in My Computer.
I managed to strip it down to this.
So the first thing I notice is that this chip is loose.
And on the underside, it has 4 metal contacts, so we know that it goes there in that missing...
