Story

Dystopian Night City Cyberpunk 2020

There be dragons...well dragon 3D-printed spikes on fabric...close enough.

Dragon Con is my favorite cosplay fandom event I attend every year in Atlanta.

I like to set challenges for myself when I make new costumes, using something I already know and adding something new, everythings a remix.

I usually say I make everything with love... and few curse words.

Potion List: Using my Ultimaker S5 and a Circuit Playground Express from Adafruit mixed with some Neopixels, I was able to program the LEDs to light-up with movement.

The LEDs in the shoulder piece are simple surface mount LEDs, with a push button and a CR2016 coin cell battery(held together with copper tape) that I designed in KiCad. I didn't plan out the PCB that well, hence the copper tape. Also poor planning on my part, because I ended up just using some double sided tape to get the PCB to stay attached to the shoulder piece the entire night.

I'll attempt to improve the PCB for that design and *gasps* maybe share it in the future. I think I'll have OSH Park print my circuit boards next round.

3D Printer Magic

3D Printer Settings

CPE is easy to print with and with the right print settings gives a nice icy FX. I started the print and after the first 2 layers, pause the printer and lay down your fabric(works best on porous fabrics). You can tape down the edge of the fabric to the build plate with painters tape, just make sure that it is not overlaying in the way of the print or nozzle area.

Uploading the Code to the Circuit Playground

Take your micro USB cable and plug it into the computer and the Circuit Playground Express. Press the RESET button to put the Circuit Playground into programming mode(the light on the Circuit Playground will turn green). From the file explorer on your computer, click and drag you code file you downloaded onto CPLAYBOOT (this is what the computer recognizes/names the Circuit Playground).

Words of Wisdom

Make sure your Micro USB Cable is for data transfer, some micro usb cables are just for charging and don't transfer data, you won't be able to upload the code to the Circuit Playground.

Custom parts and enclosures

3D Printed Spikes on Fabric

The Dragon spikes were based on Dave Shorey Designs 3D Printing on fabric design and I modified the design for my bodysuit and corset.
