How to Make Your Own Rc Car Recever Glitch Buster for $1


Introduction: How to Make Your Own Rc Car Recever Glitch Buster for $1

The novak glitch buster is a cool rc car component that filters static or noise from an rc car receiver but it's hard to find at hobby shops and a little expensive for what your getting, so here's how to make your own for $1 in five minutes.


Step 1: The Parts Needed

A 10 to 16v 2000 to 6700+µf capacitor you can get these at radio shack.
A receiver input plug you can get these at the hobby shop.

 A soldering iron and solder

Step 2: Building It

Now tin the wires on the capacitor and receiver plug then solder the wires together, makeing sure not to reverse the polarity.


Step 3: Your Done

Now plug the glitch buster into an open port in your receiver and your done.

    Don't plug it in backwards tho ;)

    It accomplishes a voltage stabilization. Very obvious from the wiring, it is plugged in an unused socket. Frequency: unimportant. Size: bigger is better but more expensive.

    When current bursts happen (like a motor running), the voltage provided by a battery has some down-peaks. This happens because the internal resistance of a power source never is zero. A capacitor can be a great aid for giving an additional boost when short current peaks appear because of its very low resistance, therefore the voltage will be more stable and the reciever will do a better job.

    Even better: Use a Gold-Cap and an electrolyt-condensator in parallel. Together they cover a greater frequency spectrum.

    hi mak89,

    thanks for the extremely well-put-together info on why this would work!

    i have already ordered myself a 4700uF electrolytic capacitor, 10v, but i really really want to add a Gold-Cap into this rig as well, but am unsure of how to wire it into the wire ???

    would the gold-cap go in-between the electrolytic and one of the wires, if so, which wire, would it matter which one ?

    also what voltage does the gold-cap need to be ?

    i have also only found my buggy's power source is only 4.8v (4 x AA batteries!) but i can only find gold-caps upto 5.5v, so would this mean i'd need two of these at-least ???

    i realise this post is quite old but i would greatly appreciate you help here as my buggy's electronics are so cheap, including the really cheaply made radio gear, i need to give it all the possible help i can !!

    many many thanks in advance if you could respond!

    & a major thanks to coolpizzadude for the instrucable !!!

    Hi offtherails2010, thanks for the flowers! =)

    The 4700 uF Cap and the Cold-Cap need to be connected in parallel (

    Both capacitors will most likely have a marking on the case which indicates the negative connection. You can see that in Step 1 and 2, where the capacitor has a big golden stripe with black minus signs on it. Your should have something very similar.

    Now all you have to do is solder those negative connections to the black wire from the plug, and the others (positive) connections go to the red wire. The white (or sometimes yellow) wire is not needed.

    Gold-Caps with 5.5V maximum voltage should work when you are using rechargeable batteries, because they should not deliver more than 4x 1.32 = 5.28 volts when fully charged. However, standard batteries deliver 1.5 volts when fresh, and I doubt a Gold-Cap will find 6 volts very funny, so be aware of this and don't kill your expensive Gold-Cap. ;)

    And of course, as those caps are polar (meaning the have a plus and minus connection), you should never switch the polarity, because then they will explode. Belive me, it does not smell like roses. ;)

    lol @ " and I doubt a Gold-Cap will find 6 volts very funny" !!!!! mak89 --- i am EXTREMELY Grateful !!!!!!

    I very much-so so so appreciate your help here, as i am new to electronics and only started learning this year (at 34 years old !!!), made my 1st perfboard knight rider circuit here for RC vehicles which kind of worked 1st time, lol !!!!

    I totally get the polar capacitor importance and am very happy to see the experts (YOU!!) not being lazy in thier explanations of them and what would seem to be questions asked hundreds of times to you, so please accept my most-sincere thanks !

    i have found 10v 4700uF capacitors very easily enough but am finding it near-impossible to find a high capacitance 10v Gold-Cap, could you possibly direct me to one being sold on ebay or on a company's webpage so i can see for myself the proper statistics, characteristics and more importantly, price!!

    I dont mind paying upto £5 for each one (about $7.92), as i will need two as whatever mods i do for myself, i also do for my friend !!

    many thanks in advance and i am truly grateful for your help !

    You're never to old to learn something new. ;)

    As I said, Gold Caps with max. 5.5V should be enough - you don't need to search for higher voltage if you use them with 4 rechargeable batteries. As for Ebay, i recommend this:

    Just remember: 1000 uF = 1 mF and 1000 mF = 1F (which is very much). You already have a 4.7 mF capacitor, so you would need a Gold Cap with at least 100 mF = 0.1 F.

    Okay okay so this is the last time i bug you about this, i promise!!!

    I have finally found and bought a 6.8mF electrolytic capacitor to go along with the two 1mF Gold Cap capacitors to make my ULTRA Glitch Buster for my RC Buggy !!!

    But... I had to wire-up the two Gold-Cap's in series because the software i am using said that they would instantly be blown as soon as my RC Power Pack was connected to them if they were in parallel (RC power-pack being 5.6v with 4 x Rechargeable AA batteries @ 1.4v each and the Gold-Cap's are only 5.5v each!) !

    So the 6.8mF electrolytic is in parallel with the two Gold-Cap's in series in the circuit i am about to etch but would like a quick 'look' from you to just confirm what i'm about to make is, in theory, what coolpizzadude's instructable is indeed telling us to make!!!

    HERE is my circuit diagram!

    Also i do realize that tampering with my RC Receiver is totally up-to ME and you bear NO RESPONSIBILITY for DAMAGE caused to my electronics for whatever advice you give, because at the end of the day, its MY choice to tinker & tamper with my gear!

    {A little disclaimer to help you sleep at night just in case i solder something wrong & it all goes BANG - lol x2! }

    please please please could you help us one last time & many thanks in advance !!!


    You may ask me as much questions as you want! ;)

    I took a glance at the two first links, and it appears you like it BIG! :D Are you aware that both caps are 3cm a.k.a. two fingers high? Just that you will find a spot in your RC-car to put them in.

    Your Gold Caps are capable of withstanding up to 6.3V peak, so I'm not sure if it is really necessary to connect them in series. Does your Power Pack really deliver 5.6V? I think this is more of a peak value just after charging, in normal conditions your Power Pack will deliver less, usually lower than 5V. How about measuring your pack with a multimeter? Then you know what's really going on without assumptions. I would recommend measurements before and after charging and usage (so a total of 4), leaving some time between charging and usage (at least 5 minutes).

    Considering the circuit, I must say that the diodes (green arrows) will make your circuit unusable. Think of them as one way valves. When you connect the circuit to your battery pack, the Gold Caps will charge, however they can not supply any current to the rest of the world, because the diodes are blocking. The electrolytic cap on the other side will have a lazy day, because he can't even charge.

    So what you want is your circuit minus the diodes. If your measuring less than 5.5V on your pack, I would even recommend changing the series connection of the Gold Caps to a parallel one.

    And yes, all your work will blow up and I am not responsible for it! hahahahHAHAHAAHAAA! ^^ *maniac laughter*

    Just kidding, take care about the polarity and don't hit the caps with overvoltage, then you're ok. ;)

    !!! DUDE !!!

    Your like, totally AWESOME !!!! I'm sooooooooo grateful for the help !

    Yaa - i dont like doing things by halves, mainly because 'Overkill is sooooooo Under-Rated' lol !!!

    And as always, a well seasoned pro in electronics (You!) is always right!

    - I measured the power pack of the RC car about 30 minutes after we finished racing and it was reading 5.16v with my multimeter, then measured each cell, about 1.29v per AA....

    Also measured a set of four freshly charged AA batteries and the max reading was 5.20v, so again, your totally right, the caps can all go in parallel, did away with all the diodes too, HERE is the simplified circuit for my ULTRA Glitch-Buster and also the PCB i am about to etch HERE.

    I completely realize that the capacitor spaces on the PCB for the Gold-Caps are the wrong size, they should be RECTANGLE, but my software is very basic and i couldn't be bothered designing a new component but i did a test print and the spacing for the leads are a perfect-fit !

    Please please please would you be gracious enough to give my new plans a quick look & tell me if its theoretically viable for me to go ahead and start the etching ?!!!?

    & Yup, the sheer size of the finished Ultra-Glitch-Buster doesn't matter, one-way or-another, i'll find a space for it ! Our RC Cars are so cheap & nasty that they need all the help they can get!

    Once again i am truly grateful for you taking the time to help me 'perfect' my design so my poor cheaply-made RC car can have one less problem !

    "Overkill is sooooooo Under-Rated" - Bwahaha! :D Me gusta! ^^

    The PCB is OK, the capacitors are correct between each other. As long as you don't switch the cables going to the receiver, you're fine.

    I'm curious: Why are you making such a complicated PCB design? If I were you, I'd put them in a straight line from left to right with the + on top, aligning the connector in the same way. Can you attach this arrangement better?

    PS: For creating PCBs and schematics, I use the freeware KiCad (, which I really love. Have a look at some tutorials on Youtube when you're struggling, but don't give up! Once you master this program, you can do anything you will ever need. And I can tell you by experience, this software is better than the one I have to use at work...

    PPS: Do you know that when you connect two identical caps in series, the total capacitance will be 50% of a single cap? It's the same as the parallel connection of two resistors, which halves their resistance. So series connection of capacitors and parallel connection of resistors (and inductors) are bad, for various reasons. If you want to know more details, feel free to send me your questions.

    DUDE !!

    Your truly LEGENDARY !!!

    ive just bought two 0.1 gold caps from the netherlands !!! one for me and one for me buddy !!

    Also my buddy said a MAJOR thanks to you for further educating us both on the capacitor farad conversions which we are both trying to wrap our heads around, your quick explanations have been written down on paper, microsoft word, notepad and will be referred-to on a very regular basis !!!

    I applaud the way you handle these questions as its very RARE that i get any responses for electronics help as my googling skills are not very good although thats where ive learnt the most and will always try to bother goolge first !!!

    A GREAT many thanks again my friend !!! You are totally AWESOME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Great ible check out my rc ibles too :)
