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.

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.

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

MakeCode for Adafruit Boards

MakeCode Maker is an easy-to-use block-based programming editor that runs in the Google Chrome web browser. It’s has an intuitive interface and features lots of examples and demos.

The Maker version works with supported Adafruit boards, so you can make interactive projects with a wide selection of microcontroller boards.

Pair Device and Upload

Once you have the MakeCode program open, click the edit button on the top right to open it in a new MakeCode project.

The code blocks and simulator will be ready to modify. Let's get the device paired with WebUSB.

  1. Click on the Gear icon, at the top right.
  2. Select Pair Device from the dropdown.
  3. For the Circuit Playground Express, Click on CPlay Express and Connect. 
  4. Click the big blue Download button to upload the code.

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
How is it related to makecode.adafruit.com ?

makecode.adafruit.com and maker.makecode.com are editors built using the MakeCode project. In both editors, one can use drag-and-drop blocks or JavaScript to program micro-controllers.

  • makecode.adafruit.com specifically applies to the Adafruit Circuit Playground Express only
  • maker.makecode.com aims at supporting the Adafruit Express boards (and more boards from different manufacturers), with an emphasis on breadboarding support.
Is it open source?

Yes, Maker is open source under MIT at https://github.com/Microsoft/pxt-maker.

Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below.

Slice with settings for PLA material. 


The parts were sliced using CURA using the slice settings below.

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed
  • Supports: Everywhere, Angle 40 degrees

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.
