I always find it annoying when I'm trying to build a prototyping involving breadboards, servos, motors, and wires, and nothing wants to stay in place. By using clay, though it's easy to hold your components in place while still being able to move them if you need to. I use oil-based clay because it's always malleable and ready to be shaped, and you don't need to store it in any special fashion. Happy prototyping!If you think this is a good tip, please vote for this Instructable in the Electronics Tips and Tricks contest!
