It may report audio and the play again the recording. It even has an illuminated bar graph to point the capability of the canister, similar to within the film.

As an alternative of making the 3D mannequin from scratch as Chris was doing, Plecter began with an present mannequin created by Microwavabletofoo and uploaded to Thingiverse. Plecter 3D-printed the reproduction canister in a number of items utilizing yellow and black PLA, ABS, and translucent Zortrax Z-GLASS filament for the capability gauge window. Behind that window is a mini bar graph product of WS2812B individually addressable RGB LEDs on an OSH Park protoboard.
