Hi All,

This is my second instructable: Arduino chandelier from mini jars. My first one was my : Cuckoo Alarm Clock from Hard Drive.

I wanted to give my room some special design, with mooth lighting so when I had the option to use RGB leds and a Arduino board I decided I needed my own making a chandelier.

Step 1: Intro: Gallery

Before we get started we are going to need a little bit of motivation, take a look at these pictures and realize what you will be making.

This project very tedious and time consuming. Any time that you get frustrated while making this project, take a deep breath, come back to this step, take a look at the pictures and remember what you are working towards!

Hi! I want to do one like yours since a year or so. Now I'm for it. Only a question before buying the littles glass jars, what size are them? I have come to find 18X40mm, 16X35mm and 10X18mm. Which would you recommend me?

Thanks and keep up with the good work!

The mini glass jars is 16X35mm, it is the best choice. Wish you have a beautiful chandelier.

Hey there im new with arduino and well i wanna try this project, do yo have the code of this project? hope you can share it :D

Would you be able to do this for an Arduino uno?

Awesome Project! It would be cool if you had it change colors/move to music!

you said to connect four pieces of copper wire to the LEDs, but only three pieces are connected to the PCB. What happens with the fourth copper wire?

how many Ohms are the SMD Resistors?

Hii i really loved this but i kind of suck at electronics and want to start to learn so please could u like guide us step by step on how its made the pcd deaign and where the copper wire connections are connected on the pcb . Thank i would be great fulll thankss
funelab (author)  rehan syed9 months ago

You can learn how to make a PCB in other Instructable http://www.instructables.com/howto/Home+made+PCB/

In addition, you will find the copper wire connection point on the circuit board, which is the output of the shift register IC 74HC595, behind the resistors.

Where did you get the LED Board? Or did you make it yourself?

funelab (author)  LupaWulfe989 months ago

I had to design their own printed circuit boards, so if you want one, please wait for a month, I will sell the kit on Etsy.com. Thanks!

Do they have to have their own board? or will it work without it?

funelab (author)  LupaWulfe989 months ago

It includes a complete circuit boards, just plug in and enjoy.

Sadly, I won't be able to for the kit on Etsy. Will the chandelier work without the LEDs having their own boards?

funelab (author)  LupaWulfe989 months ago

If you do not have the circuit board, the LEDs will light without control, it's like you get directly the LEDs on the power supply and it will remain on until you disconnect power.

LupaWulfe989 months ago

on the circuit board, what are these?

funelab (author)  LupaWulfe989 months ago

It is the SMD resistors.

Where would I get those? what is their purpose?

LupaWulfe989 months ago

Where is the resistor attached? Also, how did you design the circuit board?

funelab (author)  LupaWulfe989 months ago

Let's start with Eagle PCB tutorials.

Sir. U r project was so nice .
Could u. Please. Upload a clear circuit diagram photo
funelab (author)  ashin19949 months ago

In Step 5, Just Right-click in the download link (LampJars.sch) and click "Save link as" line ==> Have fun! This file is opened by Eagle Software version 6.4 or higher.

How do you hook th batteries up to the cicuit board? And how do you recharge the batteries?

funelab (author)  LupaWulfe989 months ago

I have designed 2 wire connector on the external adapter to charge the battery. The battery is mounted on the circuit board by plastic wire ties.

What is the difference between the Octal Bus Tranceiver and the 8-bit shift registers?

And where in the project were the Octal Bus trancievers used?

funelab (author)  LupaWulfe989 months ago

Arduino mini with lower 20mA output curent, but I used up to 19 shift register IC. So, I used Octal Bus Transceiver 74hc245d to increase the output current of the Arduino Mini. I connected to the Arduino board and 74HC595 via 74HC245, a standard SPI interface consists of three bus Data, Clock and Latch.

Thanks :) , i have a little problem when i try to download the eagle file this site show's up ??!!

when i click on the file :( ?

Thanks in advance

i was asking where did you used the Octal Bus Transceiver 74hc245d SMD

and what does SMD means ?? :)

Thanks in advance.

funelab (author)  m.tech.s312 months ago

"Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards(PCBs). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board for components not suited to surface mounting such as large transformers and heat-sinked power semiconductors." from Wikipedia.

It's just the package of chip, sorry for late reply.

So leaving the copper wires exposed is safe? they won't like over heat or corrode? idk I'm just wondering Bc they look so thin. lol
funelab (author)  mconde412 months ago

Copper wire coated with a very thin layer of insulation, low-voltage (5V) & low-current (15mA) is very safe. The copper wires break easily if there is a strong force.

sboasso1 year ago

great project... one thing: the copper whire is coated true? where i can get a spool like yours?

Also looking into doing this awesome Instructable! Any idea on the thickness of the wire? Also, you could use different coloured copper wire:
