Introduction: R/C Car Remote Detonator

Picture of R/C Car Remote Detonator

this is a really cool remote detonater that utilizes an R/C car. I haven't yet desighned an igniter to go with it, but im sure you can find one on this site, but it does work wiht a modded model rocket igniter. also i need to be sure to give somebody else credit for this because i think i saw it somewere else on this site but im not sure were. im also sorry about the bad pics, but its the best i could do cuz i already built it.

Step 1: Take Apart the R/C Car

i think this is really self explanatory. take the thing apart. on mine i was able to strip it right down to the circut board box, but if you cant i would recomend cutting it. after you get it pretty much stripped you should (at least mine did) come to to the cassi and the circut box, which just popped right out. but be sure if you cut it to make sure that the battery compartment is not destroyed. THE BATTERY COMPARTMENT SHOULD BE CONNECTED TO THE CIRCUT BOX OR IT WILL NOT WORK!!!!

Step 2: Cut and Splice the Wires

the next step is to cut and splice the wires. be sure to cut the wires leading to the back motor, the one that drives the car, because this one gets more electriccity as it is a more powerfull motor. then just strip the ends and splice them to aligator clips.
NOTE: i just cut my aligator clips of a rocket laucher thingy, thats why theres the extra wire. i also cut my wire a little short. i would not recomend doing that.

Step 3: Fix the Antenna

next is to cover the thing in some kind of camo. i used black duct tape. and then take a straw and run part of the antenna through it and coil the rest on top of the box, then duct tape it to the side. this is so that if you have to cover it in leaves, the antenna will still stick up.

Step 4: Now Youre Done

just connect the battery and youre ready to go! note i used a 6 volt battery. i think it has to be at least a 6 volt, or 4 double A's, and it helps if theyr'e rechargable.

i made this and i'm having an issue. It works until i add a load to it. mine reads 7.6 volts when it isn't attached to anything, but when i hook it up, it reads nothing.

Sir_Warrior_1-6 it is not illegal to build use and or own one of them you can buy them from amazon for 20$ or ebay for 10$ its called a wireless firing system its used for pyrotechnic shows and modal rockits and stuff i own one as long as its not used to kill any one its legal to own

Sir_Warrior_1-6 (author)2014-08-07

Highly Illegal, Feds can raid your house and face Federal charges. BAD IDEA. FACT.

ArmySoldier22 (author)2011-03-05

While this is a great idea for a remote detonator, make sure that if you decide to build\use something like this with pyrotechnics, that you are out far away from anything. Wouldn't want a random radio frequency setting off something in your face as your hooking up the detonator.

carmaster (author)ArmySoldier222011-04-29

With this, you'd have to be within a few hundred meters for it to detonate, these RC car ranges dont go too far.

I personally think its too close for an explosion.

Wait, why not use cellphones?

Yeah, soooo, this is super old but I felt the need to comment here for others that stumble upon it as I have today. ArmySoldier is right. Your r/c detonator is a receiver. That has nothing to do with range. Receivers will receive any signal that can reach it. It doesn't have to be another r/c controller.

What does this do???????

well if you looked at the title you would see it said "remote detonator". one could then assume that this is a remote detonator.

What does a remote detonator do?????

Gilo (author)TSC2011-01-14

Remote: at a distance; away from;
detonator: something that detonates; as in KABOOOM!

I have been throught model rocketry as a kid and I have made a remote igniter.
so , it ignites something. in this case the model rocket's engine.

I also have made a remote alarm sensor in 7th grade. it senses an activity and sets off an alarm; a four-tone "beeper" i scratch-built.

thats a nice avatar iloveairsoftstuff.

btw, i used to make my own model rocket engines, airsoft. that was more than 30 years ago. so you dont know i dont know something about pyrotechs.

TSC (author)Gilo2011-01-15

Yay I think I know what it means cause I have built a few rockets and lanch one or two.

well, since i now know that you have no knowledge whatsoever about pyrotechnics, i would recomend that you simply hook up a beeper to it.

OK Thanks!!!

Connect this to a fuse, then push up. Fuse will ignite, maybe setup to light a firework.

ilpug (author)thepaul932011-01-14

a remote detonator is an electronics doohickey that causes something to blow up when you press a button. simple as that.

Gilo (author)2009-01-10

This instructable could land on the wrong hands and minds. think about it. Your title can surely attract the wrong people too.

wow. the mere fact that youre looking at it tells me alot about you....... just to let you know, i put these instructables on this website to be used for airsoft. my name says it, and if you look at my other instructables, they say it to. thats what this is desighned to do. if someone really wanted one of these to blow up or cause harm to somebody, not posting this isn't going to stop them. oh well, youre only the second person ever that has been critizising my instructables, and i know i have helped alot of people, and i have no intention of stopping posting my new airsoft ideas and discoverys, so i guess i will just take the good with the bad

hey. take it easy. I have nothing against your instructable, i like it. its just that "remote detonator" is just a bit so so in this day and age. and blowing up things is the first thing that comes to mind. just be responsible with titles, at least. I am all about sharing things and knowledge. You have good one there, no doubt. cheers.

sorry. thanks anyway though. it's just that i desighn this stuff with safety in mind, and many people (like the school principle) don't understand. it's just nice to come on to a web site like instructables where i can be appreciated for the things that i do and invent and can express my thoughts openly without worrying about critisism from overly cautious people who think anything that has to do with a match is gonna kill everybody. and about the name, i would change it, but i don't think anything else would fit. if you have an idea, tell me and i might change it.

i agree. people think that any kid talking about cherry bombs is a terrorist these days. people need to relax.

ilpug (author)2011-01-14

there are different funtions on the remote. you coule rig it to be hooked to four different sets of fuse wires, and activate each one on its own, by pressing up/down or left right.

raykholo (author)2009-02-28

its a really easy concept that will work with many applications... just hook up a relay in place of one of the motors (or even both) and then wire whatever u need (igniters, whatever...) then press the appropriate button to detonate... just saying that theres an easier + more efficient way to do this, as well as easier to explain..

jrigvd (author)raykholo2010-11-27

i have made a 4 channel remote for my detonator

ya. ive kind of already got that concept down, and i didn't feel the need to explain it in alot of detail because the concept is kind of implyed

ok -- then my bad just thought that if someone wanted to mod it, ot something like that , some of this info might have helped... but ur right

roycetaft (author)2010-05-17

I did the same thing not too long ago. I didn't have the fancy duct tape, but I had an old Ipod Nano box that did the trick. I didn't use relays as some people below had mention. I used the rechargable battery pack that the car came with to power the car's circut board and ran wires right out from the the wheel's power output to a model rocket engine ignitor. Worked as easily as said.
(Basicly restating what you said)

The only thing is, look out for interference. Wouldn't want a homemade explosize going off before you have the camera ready!

zipzapper859 (author)2010-03-20

i just made one. it is acually really easy to make. i am going to use it for many things

Colonel88 (author)2009-11-04

That car looks too expensive  for a detonator...

butthead95 (author)2009-07-28

u could always just use a glowplug for the fact that you can stick a fuse inside for easy ignition

zizou361 (author)2009-07-23

I made one of these, and i am wondering if it would be possible to add a disposable cameras flash/Capacitor setup to give this a bit more kick, and if it is, how to do it?

nope you don't need it and it would fry the circutry. u can try it though and tell me how it works.

fgfgh (author)2009-06-28

what do you mean by detonate?

bombmaker2 (author)fgfgh2009-07-11

make sumthing blow up

shmickley (author)2009-02-03

if any one wants to know a zenifer diode rated below the batteries voltage connected positive to negative aka connected backwards will glow red hot when power goes threw it this is hot enough to light most fuses, gunpowder, flash powder or a sparkler (there really cheap, easy and are good slow burning fuses) zenifer diodes are really cheap available from any electronics supply store in bulk they are probly cheaper then LED'S

cool. how long will these last, like how many things will they ignite before they burn out??

i did mean zener diode i just have bad spelling. regarding the rating the further below the rating is from what u are using the more heat/energy will be produced as regarding amps the more or less it's rated for will determine stuff like how hot it can get how fast it heats up. regarding how long they will last will be determinant by resistance, what ur lighting, size, input, how long it will be outputting heat ect so its kind of hard to say unless the diode is directly connected to what ur lighting/exploding then its most likely to get damages really quickly . the way u using the diodes here are generally good for thing with low flash points as if they heat up to much they will melt if your planing on lighting magnesium or thermight go with a filament from a light bulb and use the correct voltage/amps as light bulbs are generally of high quality and are made to be used at high temps and used frequently

thanks. i have actually found nichrome wire to work very well, but only once. it will ignite visco, but ignites black match (paper fuse) better. i might try this though.

oh, i btw i looked it up on ebay, and did you mean a zener diode? if u do i think this might work better than nichrome, it does half to be rated lower, right, so with this i would have to have something that is rated below 6 volts right, and do amps or ohms matter at all?

codongolev (author)2009-01-10

wow. this would be so useful (I have heard so many horror stories here on instructables about short fuses).
