Final Project

Light Tunnel Version 3

Lighting project background

What Dose it do?

It is an art project, which is a luminous tunnel with colorful, attractive and interactive LED lights, the audience can enjoy the view while walking through it and interacting with it, and it will be installed in the gardens or on a walkway on the sea or on the corniche

Who has done what beforehand?

in 2018 i was working in fabLab jubail and we had art festivial that is comming on april 2018 ,and i have been asked to do something for the lab so they can demonstrate it in the festivel, so i was looking for ideas for something that mix art with technology, so my manager showed me this video for a festival in bahrain a one year ago and asked me can you do something like this, he is refering to the light tunnel specially in this video

so i said its logically doable, iam not sure but i can try to do it if you provide me with the materials, so he said ok go ahead and do yuor best, so i accepted the challnege.

after three weeks of searching and working with the resources that was available in the lab i have created my first outdoor project

Light Tunnel V1

Light tunnel V2

after three month somone from that art event was impressed with my project and reached me out to make another on, my first project was 21 arch with one color on each arch only, this guy was asking for 34 arch and with 6 colors led light, and what makes the challenge even harder he asked me to do it in 10 days and i was fasting during Ramadan season.

inspiration from Pinterst

for the third version of the light tunnel i want to change a littile bit from the arch design, so i was searching on pinterst for new ideas i found this project by Jordan Greene from Atlanta its look intersting so i decided to build something similer and put my own touch to it.

Final Project Sketch

putting all things together the plan is to make V3 of my light tunnel, with the things i will learn in the academy iam sure there will be a chance for developing new version, , putting in mind that the devices that available on market today is expensive i want to design my own electronics for that.


for the final project, we were asked to incorporate 2D and 3D designs, additive and subtractive fabrication processes, electronics design and production, embedded microcontroller and programming, system integration, and packaging. and in this section i will answer the following

Electronics design and production and Embedded programming

Looking for the right led to work with

i know that it will work with NEOPIXELS but it bit expensive to buy from outside and the ship it here so i started to look for led to control in local shops, after looking around for several days i found one is good to be work on,


Understanding the pins

what i understand that after multiple test that if i want to control each pixel or led in the strip i have to make sure to have 3 pins,


So i made a search on the net i found this tutorial for wiring the addressable led with Arduino,

Sktech i connected the power 12V and connect the Data pin to Arduino

FastLed Liberary

then i downloaded FastLed Library for Arduino and made the first test.

Make Arduino stand alone controller

After the successful test i wanted to make something and install it in my room, at this Time i have finished the Computer controlled cutting week so i made the case using Maker Case and put my Arduno UNO inside it

Lighting up my room

Then i installed it in My room and here how it looks like


Test with Attiny 45 and Attiny85

Then during the output week I used the board i have designed during input week and tested the led with Attiny 85 , and attiny45

margin cut


Board Design

i used Kicad to design this board you can refer to input device for full details about it munzir al radi board

munzir al radi board

generate a tool-path

munzir al radi board

Mill it with SRM-20

after that send the file to the printer to start milling it , you can refer to my assignment electronic production for more information about the exact steps to cut the machine


Milling Result

LED —- Attiny45

Red —- »> 12 V White —- »> GND Green —- »> pb0
GND —- »> GND

Make sure to connect the gnd to together so the signal will stable

i used the liberrary FastLED to sontrol the strip light


the first problem was that the memory was not enough in the attiny45 pwm


to solve these issue

with sequencing


What i found out is that Attiny 85 Have bigger memory than Attiny 45 but also it was not satisfying enough for me so i will change it to Something else


During Networking And Communications Week i designed a new board using atmega328au because it has more pins and memory, check the datasheet for more information about it.


microchip parametric


I used Kicad design the board

you can refer to Networking And Communications Week for full information about the board

Milling the Board

i Used SRM-20 for milling it , you can refer to my assignment electronic production for more information about the exact steps to cut the machine


Solder the Board

Then I soldered the board schematic

2D and 3D designs and Fabrication processes


Designed a joint for the Structure

the project structure is a Hexagon Shape, and in order to make the shape be easily assembled and de assembled i decided to design a 120' joint on each angle, and X shape joint to be attached together and hold each hexagon, i did the design on computer aided design week

joint joint

Using 3D printer

for printing the joints i used Ultimaker extended 2+ 3D printer and Creality CR-10 , and used PLA 2.85mm filament joint

Printing process

Mold and Cast

During Molding and casting week i have designed a mold for the joint in order to make the production of it easier and faster, i made a wax mold then i por into it a silicon and mad the soft mold then i applied to it Smooth-Cast™ 305 material from Smooth-cast

Time-lapse video for me making the design

And then making the mill and mold

Result of the mold

this is the final result for the silicon mold


Final result for the mold

Here is because the material i used it has some softness it stretched when i took it out of the mold , but the result was good to see the exact location for the holes and how they are connected to each other


2D Design and using CNC

Jordan Greene

For the 2D design i used VCarve pro to design the structure for my project because it can produce a toolpath that i can use immediately to Shopbot CNC


I used MDF 18mm thikness for the structure of my project and Shopboot PRSalpha 96-48 to cut the materil

System Integration

i used wood glue to hold the base of the hexagon together

then connected the led and electronics together

what materials and components i used?


i will use MDf wood becouse its cheaper and available in the lab

Electronic PCB
3D printer

the project structure is a Hexagon Shape, and in order to make the shape be easily assembled and de assembled i decided to design a 120’ joint on each angle, and then i will use 3D printer to print it

where will they come from?

Most of the materials and electronics components that I have mentioned are available in our lab and some of them i will buy it from local store Like Adressable LEDS, and to lower the cost I ordered them from Amazon SA.

how much will they cost?

Total Cost will be 210.75
