Upon setting out to build a simple track for my 3yo son and I to play on, I was discouraged to find how difficult it is to get/make either a slim-featured electronic or even simple mechanical finish line. After quite a while searching the web and viewing multiple different finish line options, I finally had a bit of an epiphany. I'll use my experience with online coding languages and make my own darn finish line!
At this point I have a promising proof-of-concept and am a third of the way to a working prototype (I don't even have a track yet!). I'm hoping to do a full walk-through on how to do this as I refine the process. In the meantime, here's a hint to get your collective taste buds salivating. I'm a complete novice at any lower level electrical work, so fear not, I will create a SIMPLE project!
