Giancarlo’s Physical/Digital Spray can (Final Project)

i made, what i call, “street art magic” — a physical/digital spray can

essentially it’s a symbol for the use of spray cans and their connection to street art in the digital age. 

this one works as a can, or trigger, for the acrylic tag that i constructed to become a light. the use case would be someone who is a fan of graffiti and just wants a novel spray can that lights up a tag; however, it would be great for the setup to be used as a communication tool for young artists to non-verbally communicate when they arrive hone after a night on the streets. Being that Huzzahs are [going to be] used, the cans can trigger lights that are remote (another town, city, state) by using WiFi. 

overall the process was undulant but the challenges made it worthwhile in the end. currently the product and video, themselves, are only a work-in-progress, due to challenging software/hardware interface issues. the current production uses acrylic to display the tag and diffuse light, with a 3D printed casing to wall mount and house the neopixel strip. 

this seems like an appropriate time, so the materials are as follows: 

  1. 2 acrylic sheets (fill and outline)
  2. 3D printed case 
  3. 315/433mhz RF transmitter/receiver (if wanting to create a local remote to trigger) 
  4. Arduino Gemma (if wired version, current prototype) 
  5. Arduino Huzzah (if WiFi version, to interface with others) 
  6. Arduino Huzzah/Metro (if using RF transmitters, for a local remote trigger) 
  7. Dozen (approximately) pvc coated wires 
  8. Neopixel strip 
  9. External Battery 
  10. Button 

In using the materials, I tried to manage my time efficiently so I could work on the various pieces of the project concurrently. Almost all software and hardware resulted of new endeavors, but it wasn’t too overwhelming (other than the RF module being defective). 

Process photos and explanation: 

Wiring photo (RF attempts, Current modified button cycler, and Huzzah); Tag sketch (in notepad); Laser Cutter; 3D model for case 

Overall I’m satisfied with the current state of the project, but my next steps for the near-future iterations will use both the RF module and Arduino Huzzah (for the local, and/or remote LED triggering spray cans).

The telepresence chairs have transformed into telepresence hands that you can put on your desk, give to a significant other, and hold hands together (while apart). The model for that one looks solid, but I printed it on the wrong side and print failed. No biggie.

The spray can is not a digital spray can anymore (unless the digital interfacing works very well) or it will be on hold till version 2.0. I think as a trigger turning on a laser cut tag would be dope.

Storyboard: Just words for now

SPRAY CAN: Its night, a kid is spray painting (graffiti), he hears people (maybe the cops) coming, he runs, frantically opens his house door, clicks can (fake sound like regular can earlier painting), light turns on illuminating his room

HANDS: It’s night agin, a student is doing work, video pans to his significant other at home, the student stops, holds onto fake hand on his desk, the other person’s hand lights up, they hold theirs, they are now holding hands together (but apart).


Giancarlo — more IoT exercises and Final ideation

Final Project

Here is a continuation of my final project ideation. I’m going to continue with the spray can and chairs (two separate projects). Ideally, I would like the spray can to work on adobe or similar software, as a digital spray can (with varying stroke weights) similar to a wacom pen without the pen pad. For the chairs, I am pretty pumped from them, as I’m currently designing a set of chairs to be used. I am unsure how I would like for the telepresence part to be shown on each, a heat map would be amazing, but I think that’s outside of the scope for this project. If possible, it would be great, though. I don’t know which will be the main focus (but why not both).

So, here are the materials that will be needed for the digital spray can:

  1. Spray Can casing (which I will 3D print on the machine Liam and I now own)
  2. LED
  3. Sensor/Button
  4. Arduino Feather (or another WiFi capable board)
  5. LED screen/Interface (for the spray can to interact with)

Materials needed the telepresence chairs:

  1. Chair Frames (CNC’d)
  2. LEDs (for telepresence)
  3. Sensor (to be notified when the chair is being used)
  4. Arduino Feather (2x for each of the chairs to interface with each other)


Unfortunately I couldn’t connect to any working WiFi, like last week, for the IoT homework (although I did try 3 hotspots and 2 routers). So I did not have any luck with continuing with the sensor and Adafruit compatibility. I do have the accounts made for each, though.

Giancarlo Cipri — Qui-Gon Jinn Halloween Costume



For the 2021 Halloween Parade I was Qui-Gon Jinn (Liam Neeson’s character) from Star Wars.

Why this costume?

I decided to do Qui-Gon Jinn, since I am a huge Star Wars fan and his character is (SPOILER) unfortunately short-lived, but definitely impactful. When I was a young kid, I would always watch Star Wars Episode 1 with my mom and Qui-Gon was her favorite character. He was a great mentor, and a Jedi career highlight was finding Anakin (for better or worse).

How was it to wear?

Overall, the costume was great to wear, as it was just a super long Star Wars robe. I purchased it from Party City — as making the lightsaber from lathe to hardware and software was a tall task — but still tailored it so that the hems fit me well, the hood wasn’t absurdly long, and so it closed with velcro (thanks Marko!).


What I learned in the process

Make more lightsabers! Getting it perfect is difficult, but definitely a gratifying process. I’m glad with the way mine turned out, especially since I gave it a bit of a twist. In making my saber, I was using Qui-Gonn’s as a template, but in early iterations I added/subtracted various elements. Here are some photos of different handles/finishes.


  1. The project first started on the Lathe, where I turned a block of wood into a dowel, and then carved the dowel into the handles I currently have via different chisels.

2. After the lathe, I primed the saber and let it dry over night. Then, I drilled various holes through the middle of the saber (from top to bottom), with the final being about 3/8″ thick.

3. From there, I found what finish I wanted on the saber and actually switched from a black gloss to a black “wood stain.”

4. Then, I ran to Canal Plastics with the lightsaber crew (Cathy, Erika and Liam) for frosted polycarbonate tubing and drafting sheets. These were the LED casing and diffusion for the saber.

5. After, I refined the code and fed everything through the handle for it to be soldered, including the button.

6. Lastly, I assembled it and had some fun!

Thank you Becky for the amazing night and guidance!

Giancarlo’s Qui-Got Jinn Halloween Costume Progress

Wow, this is my third time changing Star Wars characters. Last week I mentioned that I was doing Obi-Wan, but I officially changed to Qui-Gon. After speaking with everyone, this one makes most sense — I have long hair, my favorite color is green (for the lightsaber), and the brown robe is perfect.

In terms of lightsabers, I currently have two different prototypes that I’m considering. Both were made on the lathe and will be spray painted black and silver for accents.

Here’s a progress shot of my Arduino and NeoPixel in the lightsaber.

Aside from that, I’m using some black washers, black and silver rust-o-leum spray paint, and polycarbonate tubing (that I will purchase from Canal Plastics with the lightsaber crew — Erika, Cathy and Liam).

Overall, this project has been super fun and drilling though the lightsaber was a lot less intimidating/difficult than I thought.

Giancarlo’s Halloween Costume

Costume: Obi-Wan Kenobi (Jedi Lightsaber and Robe)

The lightsaber will be made out of wood carved on the lathe — see last week’s proposal for pictures of the draft (as I’m currently doing the final model).

The lightsaber will have a hole in the middle, so I can feed the wires through for the LED and the blade of the lightsaber will be a plastic tube with Styrofoam to diffuse and stick the LED NeoPixel.

Link for the robe below


For some reason the Tinkercad doesn’t showcase different colors (and blue in my case) but it previously worked in-person.

Arduino Techniques: Fade, Loop, ON/OFF button (maybe magnetic… for the force). Hopefully I can get my Gemma to work soon.

Green Guy Night Light

Product Description

The Green (best color ever) Guy Night Light is made for children who are afraid of the dark. His LEDs shine in three different colors: white, red and blue; and they showcase the location of vital organs within the body. One can also say that this is an educational tool that promotes body awareness. These are both great problems to solve and console the user.


The Green Guy Night Light is simple in construction and is made up of the following materials:

  1. Green Corduroy (body fabric)
  2. Black Zipper (LED and stuffing enclosure)
  3. Black Thread
  4. Cotton Stuffing
  5. 3xAAA batteries
  6. 3xLEDs (white, red, blue)

Product Journey

This product was extremely fun to make as I’ve never sewn a plush toy before, nor had I used LEDs. I found it easy to sew the corduroy as it is a light fabric and the machine had no problem going over it. The most challenging part was definitely the LEDs and the indication of the organs (which I have yet to make a successful solution) through chipboard within the body. Lastly, I was most surprised to see how long it was going to take to do the LEDs.

For Future Iterations

Next, I would definitely like to refine the product by indicating which organs are being shown through embroidery (hand or machine). I had not thought of this until I had sewn the body and seen that the chipboard was not enough.

Giancarlo’s Plush Night Light Proposal

The night light plush that I will be making is in the shape of a free-form body. The intended audience is young children, and the LEDs will be placed along different body parts (head, heart, stomach, hands, feet) — for body awareness and comfort.

The left photo is of my sketches — with purpose, LED circuit and materials (hopefully). Green is my favorite color so I’m hoping that it is possible. Also, I’m planning to put a zipper on the back for easy opening/closing.

The right photo is of my two sewing sketches.

My only concern is that velvet, corduroy and suede all have the tendency to be thick/opaque. I hope this is not the case in terms of LED diffusion.

Also, I do think it would be pretty cool to have a child and parent version, TBD as a result of the single figure.

Lastly, here’s my attempt at wiring all LEDs; however, I could only get 3/7 to light.
