Still think the wireless keychain is so baller.

But watching the homemade video reminded me of a few past projects, wanted to pass a tip along to you.
MAKE SURE you triple check all switches and connections BEFORE you start gluing/taping/heatshrinking what have you.
And even with "simple" projects like this, it's still a really good idea to wear safety glasses (yes my Dad was a shop teacher) during the entire process. I willing to bet, for sure, that every old fart tinkerer on here as had something fly up into his face.
Wait... that sounded weird.
