DIY RC Fireworks Ignition System

This Instructable will show you how to make a safe remote controlled fireworks detonator that reduces accidents like skin burn and accidental explosions. Every year hhere in the Philippines All you need is $10, 30 minutes of time, RC Car, Chopsticks, 6 volts VRLA battery, Wire and a Container. Please rate this as a 5 star. Have a Happy New Year.

Definition:
RC detonator - Circuit that allows you to ignite fireworks without using a match. Just press the button on the remote and the fireworks ignites


There is a video at the last page "it was really fun.
Me and my father had a great time.
We had a lot of fireworks.

Cool idea.

[icekid]

Cool it's easy to make, cheap and effective.
Hey everyone try this it works.  !!!!!!!!!!!!!!!!!!!!!!!

[ASCAS]

The relay can be found anywhere one example is radio shack.
The relay depends on the RC circuit or RC car's output voltage, I tested my RC car output voltage using a digital tester and the reading was 5 Volts so I used a 5 Volt relay.

Try to read more books or search in the Internet. I am 12 years old but i know a lot about electronics i already built 9 original circuits and about 210 circuits for experimental use or modification but only 136 worked. But i dont post to much instructables becuase i am not good with designing Casings for my projects most coverings look bad but they work pretty well.

[bugmenot5]

Wow cool you must be a brainy dude. i will recomend some people to try this. But i am sure this will work. thanks dude

[watch81]

looks like a lot of fun.. i gotta try this one

[herbert1982]

that was great, thaks a lot men

[ASCAS]

Its kid. still 12

please read it and comment :)
p.s i am 13

I hate being a killjoy, but this is really dangerous. The reason RC cars are on 25/40mhz is because this frequency is not used by anything else, due to interference. I'm telling you, this WILL accidentally go off occasionally.

I'd suggest using a modified wireless camera trigger, as these have 100m+ range, ~0% interference, and are less than £15. (About $25). They are also much smaller, and have the power in them to trigger an e-match easily. Not sure if they would trigger your ignition system, but it is still safer.

On the other hand, Great 'Ible! I love to see household items repurposed! I built something just like this when I was about 8, to trigger FX charges. (Basically over-volting little capacitors). Safer than fireworks, so I did not care too much about the interference.

[ASCAS]

Interferances can happen, I believe in what your saying. In my newer verion I had used an infrared RC circuit.

You can buy a relay in radioshack. A relay is a electronic switch like a transistor but the only difference is that the relay can handle higher voltage and ampere to pass through it.

[sngehl01]

that is not entirely true. a relay can handle AC voltages while transistors can not, a transistor switches more quickly than a relay, a relay produces voltage spikes due to the coil, transistors operate on less current, if a relay burns out, the circuit stops, if a transistor burns out, it could produce and electrical short,there are quite a few differences, and each serve a purpose, plus, transistors are much cheaper. A TIP120 has a collector emitter voltage of 60 and a collector base voltage of 60. The base will take up to 5V. You could very well make a transistor driver circuit for this, but what you did works very nicely. Good work!

[electrokid]

Cool idea.
Hey try using nichrome wire-draws alot less current than copper

[nathanielg]

I am also great in the electronics area and i am 14. But i noiced one flaw in your system. If any other person is using the same frequency( in a walkie talkie, or another rc car) you will have premature or unwanted detonation of your system. this could result in a injury or worse... so i just wanted to warn you about that..... But great instructable and thank you

[pastaking]

Ditto. Try using a 2.4ghz TX/RX combo, or have two on different frequencies and wire them to relays connected in series so both have to be driggered to detonate the target.

[HamenChips]

We have the same screwdriver

[ASCAS]

Yeah but in my 2nd version of this i added a 2.8 ghz remote from a old rc helicopter :)) so the only thing that might trigger it is my wifi or my cordless phone. I recomend for you to use a rc car with a special frequency.

[monkhm]

You could just use a normal model rocket igniter :P

[charchar97]

so, im too lazy to post an instrutable, but i just used the smallest PIECE of wire that i could find and used four 1.5v batteries.

[avatar_i]

12? TWELVE years old?! OMG, I'm... much older... but I ain't got near the smarts that you do!
Bravo, Lad! Well Done!
Now, how much do you charge for tutoring...

[jpoopdog]

heres a smarter idea, get a signal relay card kit from an electronics store, then modify it by making the input signals resistors values realy low (just use weaker resistors), that power the relay switch, so you can switch high currents and voltages withsignals from 6v at below 1 miliamp. also, use a garage door opener kit, which comes rebuilt, form china costs $10 after shipping, and can transmit a signal for up to 300-400m.
use it instead of a r/c car remote and controller for 2 reasons.
1. its super weak
2. anyone else can control it because its on a universal toy car band (27mhz or 40mhz)
even walkytalkys use that band and will detonate your fireworks.

[ASCAS]

Yup! Other RC devices cannot provide enough power to burn the ignitor, like mine. So I added the relay

[iloveairsoftstuff]

nice ible, but i have one exactly like it accept without the relay.

[A.J.]

yeah, where did u get the relay? what is the trigger voltage? can i get bigger ones (for 120v)?

[imakethings]

take any 5v realy. but tou will get limiled range with this RF module.look fort aeroplane R/F modules.

[chaoschao99]

 what type of relay is this and where, and how can i buy this, what would i search on google. it would be a huge help if you could just tell me the exact name of the relay. thanks alot

[chaoschao99]

 so whats a relay and where do i buy one?

[budsiskos]

 VIDEO PLEASE :D
