LED Fireworks

Nowadays technology changed everything. Things that have been made many years ago are now appearing in a new form with new and modern parts.
So I decided to simulate fireworks with LEDs and made a machine that makes LED fireworks.
It works simple, there are a lot of LEDs that everyone is connected to a capacitor with a resistor, the machine charges the capacitors and a timer drives a motor that strews them around.

Step 1 Things You Need

To make your own LED fireworks machine you need the following things and tools:

• Some colorful LEDs
• Some 1K resistors
• Some 470uF capacitors (or higher)
• Two plastic disks
• Some screws with bolts
• A long narrow plastic strip
• 1x 1N4007 Diode
• 1x 1N4148 Diode
• 2x 100nF ceramic capacitor
• 1x TIP122 transistor
• 1x 50K potentiometer
• 1x 33K resistor
• 1x 100K resistor
• 1x 100uF electrolyte capacitor
• 1x 3.3uF electrolyte capacitor
• 1x BC547 transistor
• 1x 555 IC + socket
• 1x Simple push button
• 1x Small motor
• 1x 9V battery + connector
• Some wire
• Foil
• Drill
• Screw drivers
• Soldering iron
• Soldering oil
• Soldering wire
• Glue
• Pliers
• Wire cutter
• A bubble bag
• Things to make a PCB (if you want to have a circuit board)

Sorry, wrong contest ;D

I assume you're referring to your post in the wedding DIY contest, and I disagree! I've always wanted fireworks at my wedding but they didn't fit in the budget - now they do! :)

[agis68]

I Had fireworks and accidentaly burned my best man 's hair!!!!!!!!

[vahid_you2004]

By this machine you have fireworks but you won't burn anyone!

[roland985]

nah, you'll just poke all the guest's eyes out...

[vahid_you2004]

Yes, if you do this in closed area or near guests certainly you'll poke all the guest's eyes out!!!

[rcisneros]

Damn. I was going to say that.

[sibuadvancetech]

cool stuff!! thank you!!

[Shanjaq]

Maybe encase the cap/led/resistor modules in hot-glue to make them more durable and less of a danger to eyeballs =D

[jtmjr]

i could have used this under my tables
I really like the looks of this wish i had seen it before our reception you got my vote :)
keep me in mind when voting i built the 3 tier fruit wedding cake

Very cool! Would look like fireworks in the dark. One question: what is that song in the video? :D

[br_amar]

That song is from a bollywood movie called "DHOOM"

Here is the song:

Thank you.
I don't know; i found this song in a rigntone pack; the file name is Dhoom.mp3

Very nice job and well presented. The white disks are handmade right? from what material? (I know are made from plastic) but i mean what plastic??? please give me a response maybe you find me a solution in a big problem with my old scanner!!! You will be my hero you know!

[vahid_you2004]

I don't khow, the plastic disks was parts of a toy wheel, and the white disk is a thin layer of foil attached with glue to the disk.

It's beautiful , thanks .
But i would have used a copper wrapping around the led's ,
or you could flip the led's to north direction and lay diffrent poles of copper wrapping , the copper is attached the output and input ;)
I didn't say you should have , i only said that i would .
Peace .
