Iterate onwards, incorporating sound output.
Day 1:
Design and develop body parts from templates,
what will it do?
I am going to make a modular toy dinosaur kit incorporating some electronic behaviours. The kit is for 8-10 year olds and will allow them to freely construct their own dinosaurs, mixing body parts as they wish. The dinosaurs will be made by slotted ply construction, and copper vinyl at the interfaces will act as an electrical conduit between different body parts. Each body part will contain one element of the electrical circuit: one or more inputs, one or more outputs, processor, or power supply. For the prototype I will attempt to use 3 tilt sensor inputs and 2 LED outputs, and work onward to an additional output triggering an MP3 module, to play dinosaur sounds.who's done what beforehand?
The principle of the kit owes a great deal to the classic dinosaur kits of my youth, as well as on the electrical side of things, Ayah Bdeir's Littlebits, and Yuri Suzuki's Denki puzzles. All of these examples brilliantly capture my aim of producing a simple, fun, educational kit, very elegant in presentation such that young minds can freely explore both the possibilities and constraints of a puzzle like kit, as well as simple electronic theory and ending up with a cool dinosaur at the end too.what materials and components will be required?3mm Laser ply,

Develop integration of electronic components into body parts,
Design main circuit board,
Produce main circuit board,
Laser cut body parts,
Assemble electronic components with body parts,
Write code and upload to board,
Test first assembly
Iterate onwards, incorporating sound output.
what questions need to be answered?
What electrical implications are there for separating the various electronic components and what happens in all the combinations that they might be connected? Do those constraints fit with the pysical/geometric constraints of the kit/puzzle?what is the schedule?
As I am short of time anyway in the next few weeks, I am considering concentrating on completing previous week's assignments and tackling the final project after the course ends, in order to make the most of the tutor contact time I have remaining. This may well be ill conceived, in any case the general schedule will be:Day 1:
Design and develop body parts from templates,
Try to answer those unanswered questions.
Day 2:
Test and develop slotting together using copper vinyl,
Develop integration of electronic components into body parts,
Day 3:
Design main circuit board,
