I read this forum now for about 1 week. It is very interesting what is invented and tested on this forum.
I live near Utrecht (The Netherlands), married and we have 2 kids (boy and girl).
Two times a year we build a big (4x 25 m) analog slottrack. We do our races and after that, everything goes back in boxes.
Upgrading a slottrack to digital is expensive or the quality is bad (lot of problems and errors). After searching the internet I found this system. It is so simple, that I love it. And the best, no visual slottracks

CU, Jack.
