Rob Morrill has written a course of Circuit Playground Express projects for adafruit. One of them is the gondola which I feature here.
I didn't have to make any modifications to this one but here are a couple of notes about the materials.
I used velcro to stick the CPX to the cardboard. Better if you can find a "Heavy Duty" velcro, holds 3 kg, which I found at Bunnings.
The shelf, supported by gusset braces, for the battery is important so the gondola hangs perpendicular. Wrap a piece of masking tape all the way around the battery for extra support.
See the video for my gondola in action!
