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)
<p>haha, arent led 'fireworks' kind of an oxy moron? Last thing you want with electronics is fire...</p>
http://www.instructables.com/id/Make-a-bomb-no-potassium-nitrate-used/step3/Put-the-igniters-in-an-empty-box/ <br> <br>Please check this out. It is my first instructable. I would really appreciate it as i am only 13 :)
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! :)
I Had fireworks and accidentaly burned my best man 's hair!!!!!!!!
By this machine you have fireworks but you won't burn anyone!
nah, you'll just poke all the guest's eyes out...
Yes, if you do this in closed area or near guests certainly you'll poke all the guest's eyes out!!!
Damn. I was going to say that.<br>
cool stuff!! thank you!!
Maybe encase the cap/led/resistor modules in hot-glue to make them more durable and less of a danger to eyeballs =D
i could have used this under my tables<br>I really like the looks of this wish i had seen it before our reception you got my vote :)<br>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
That song is from a bollywood movie called &quot;DHOOM&quot;<br><br>Here is the song:<br><br>http://www.youtube.com/watch?v=9uIz1DFNJnY
Thank you. <br>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!
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 .<br>But i would have used a copper wrapping around the led's ,<br>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 ;)<br>I didn't say you should have , i only said that i would .<br>Peace .<br>
