I see there are cheap indoor wall clocks that are syncd with WWVB. But can't find anything that use gps instead. I am wondering why? Are the receivers too power hungry or the signals just too weak? I'd think going with a gps time sync would be a more future proof design.
We didn't get the briefcase either. But one officer did bring his K9. Which then tried to bite my classmate during the "come up here and pet it" session.
With ropes you can start with a basic loop that acts as a pulley. Butterfly, wireman's loop, farmers something - I forget the names.
But you basically create a loop that let's you double back your rope. With a lot of modern rope they are slippery enough you get pretty good mechanical advantage. Some folks then go to a taught line hitch or something to even keep things adjustable basically. Key is usually to give yourself enough space to tighten, and I skip the taughtline hitch in most cases.
