01: Prototype

As you’re making a lot of parts from scratch, prototyping with cardboard or paper on each step is a great way to make sure your patterns and cuts and modifications will work in real life. Remember: gluing stuff back together ranges from ‘a big pain’ to ‘impossible’.

02: Test

As with most projects, you should probably get your Raspberry Pi and custom software up and running before installing it. Testing as you go is always a great way to fix mistakes before you seal something into a case.

03: Wear

If you plan to wear it for a costume or at an event, do a trial run around your home during a normal day. You’ll quickly learn the best way to wear it without either damaging it or other things around your home, and find out how dexterous you still are.
