I wasn't sure on which Forum to post this but I was curious to know if anyone had made their own data log page? I thought about making one up in EXCEL and then printing them out and putting them in a binder. If someone has already put one together and doesn't mind sharing it would be great and give us some ideas and a basic template to work from. There are dozens of various data log book available online, but some are downright expensive! Just a thought.
