As I was bored today I desided to see how easy it would be to implement my idea for the electronic target scheme discussed a few days ago,and interestingly I have designed a cpld which does most of the work,and emailed some company that makes target scoring software and asked if they would like to see a demo of a system which is a bit cheaper than the 4 grand a seat I have seen for optical systems.You never know they might say yes as long as it doesnt involve spaghetti hoops.
