# 3D Printed Heel Clips
## Overview
Add rocket boosters to your shoes with these 3D Printed heel clips! The Heels are compatible with the Nike x Acronym Blazer Low.
The LED animations are powered by a Circuit Playground Express. The boosters light up and a pew and pew sound plays when you stomp hard!
These 3D Printed heels attach to the backs of each shoe with M3 thumb screws. The Circuit Playground his housed inside a clear case that attaches to the printed heel.
Alligator clips and machine screws make this assembly modular and can be reconfigured into different designs.
With MakeCode for the Circuit Playground Express or MakeCode Maker, we were able to quickly make this demo.
MakeCode an easy to use block based code editor that's great if you're just getting started.

## Circuit Diagram
The wiring diagram below provides a visual reference for connecting the components. It is not true to scale, it is just meant to be used as reference. This diagrams was created using the [Fritzing software package](http://fritzing.org/download/).
Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - the length of wire, position and size of components are not exact.
Wires are measured and cut to have enough slack to reach each component.
Silicone ribbon wire is used to make them easier to coil and manage each wire inside the tight spacing.
A 420mAh LiPo Battery connects to the JST port on the Circuit Playground

## What is MakeCode Maker?
**MakeCode Maker**, https://maker.makecode.com, is a web-based code editor for physical computing. It provides a block editor, similar to Scratch or Code.org, and also a JavaScript editor for more advanced users.
Some of the key features of MakeCode are:
* **web based editor:** nothing to install
* **cross platform:** works in most modern browsers from tiny phone to giant touch screens
* **compilation in the browser:** the compiler runs in your browser, it's fast and works offline
* **blocks + JavaScript:** drag and drop blocks or type JavaScript, MakeCode let's you go back and forth between the two.
* **works offline:** once you've loaded the editor, it stays cached in your browser.
* **event based runtime:** easily respond to button clicks, shake gestures and more

# 3D Printed Heel Clips
## Assembly
## Solder Wires
Measure and cut the Alligator wires short. Use ribbon cables and jumper wire to connect the NeoPixel PCBs into a shared connection.
## Thread wires
Pass the wires through the cutout for the boosters.
## Booster
Use three M2x8mm long screws to attach the two booster parts to the Heel
## Pressfit NeoPixel
The NeoPixel PCB press fits into the booster cap. Align the threads to the booster and twist to the right to tighten.
## CPX Mount
Attach the 3/8" to 1/4" Adapter Screw into the center of the CPX mount.
The battery holder attaches to the mount with M2.5x5mm long screws.
## Tripod Adapter Washer
The 3D printed washer fits over the 1/4" to 1/4" Screw adapter and then attaches to the Circuit Playground case. The washer helps to space out the case when mounted.
## Attach mount to Heel
The mount fits between the heel and is attached with two M2.5x5mm screws.
## Alligator Clips
Attach the alligator clips to the pads on the Circuit Playground.
The 420mAh lipod battery fits in the holder with the cable facing up.
Use a JST extension cable to reach the JST port on the Circuit Playground.
## Attach Heel
The heels attach to the three threads on the back of the shoes.
Use six M3x7mm PC Thumb screws to securely attach the heel assembly.
