I want to make card sync tool and have read a lot about how easy it is to make it. Like on this famous address: http://www.powerchutes.com/manometer.asp Yes, it's easy. If you can find the "simple parts". I am talking about transparent plastic tube. It's absolutely impossible to find it. I've been to car/bike parts shops, Bunnings, Jaycar, and last I've read it can be found in pharmacy. It's not there too. It's not possible to find that tubing in the internet too. Anyone made the tool? Where did you get the damn tube?
