Introduction: From Old Motors Into Signal Booster

Picture of From Old Motors Into Signal Booster

Do you have old dc motors / any motors? don't throw them! lets recycle it!

Lets make a signal booster!!


  • Phone
  • Smartphones
  • Modem
  • Wifi
  • & anything

Simple to make, Super signal booster, easy to use and carry, light and thin, And many more.

Suitable for use when an adventure, because the signal will weaken as in the wild. Insert the signal booster into your phone, and Voila your signal is increased.

OK LET'S MAKE IT!!!!!!!!!!

Step 1: You Need:

Picture of You Need:
  1. Old motors
  2. Clear tape
  3. Scissors
  4. Matchstick / lighter

Its FREE!!!

Step 2: Open the Motors, and Take the Coil

Picture of Open the Motors, and Take the Coil

Open the motors, & take the coil.

Choose the best coil to make the best signal booster (i use the yellow coil)

Step 3: Take the Wire

Picture of Take the Wire
  1. Cut the wire from the coil with scissors
  2. Roll the wire with your fingers (image 2 & 3)
  3. Make another roll (image 4 & 5)

Step 4: Burn the Wire

Picture of Burn the Wire

Use matchstick / lighter to burn the wire. Burn the two wire to make the wire receive the signal. Only burn the roll wire!

Step 5: Make the Case!

Picture of Make the Case!
  • Cut a small clear tape
  • Paste the two wire to the clear tape (image 2)
  • Cut another small clear tape
  • Paste another tape (image 4)
  • Cut the edge of the case (Image 5)

Step 6: Signal Booster Installation

Picture of Signal Booster Installation
  • Turn off your phone
  • Put the signal booster near your simcard

  • Turn on your phone
  • And see the difference!!

Step 7: Finish!

This tool is similar to the signal booster stickers. If you want to know how it works, look at google

where to place the wire under the battery ?

ThomasK19 (author)balsuryana2016-07-17

Exactly. Google tells me this is just nonsense.

MuneebS5 (author)2016-08-11

can it works with tv anteena ?

balsuryana (author)MuneebS52016-08-15

yes it can

knowledge pirate (author)2016-08-12

Dam ingenious because its so simple and it works.

SoakedinVancouver (author)2016-07-17

Hmmmm.... I would dismiss this set up out of hand but for the fact that we used to do something similar with AM radios while out in the boondocks. As in, take a non-functional AM radio, rip the small ferrite bar antenna out of it, unwrap a few meter of the wire, mount the ferrite bar on the outside of a working radio, POSITIONING THE FERRITE BAR OVER THE WORKING RADIO'S FERRITE BAR ANTENNA, and then hang the wire you previously unrolled to the rafters or what have you (tree branches, hanging deer carcass, whatever...). Your reception will be boosted up.

Now, could it be that in this author's case, no pun intended, he happened to position his rather short (i.e., high frequency "tuned"...) metallic loop just at the right spot, i.e., over the internal PC trace antenna? So, if you try his scheme, do a series of tests, moving the outside antenna all over your phone, taking a signal reading every time you move it. Also, fiddling with the length of the wire used might prove worthwhile. Of course, this setup might end up causing internal interferences via unintended module couplings, so watch out for DIMINISHING readings when moving the antenna around... Worth trying, also see if there is a pattern out there for cell phone frequency optimized fractal antenna patterns...

Good instructable, as it did get my curiosity up, and reminded me of an old trick of my foolish youth... :)

I made a hand mixer into am radio amplifier back 55 years ago. I had got a new 6 transistor radio and I could only receive 2 stations! So I build an amplifier with 4 3 feet radial wire and hooked to the coil in the mixer. Took it outside to the peak . I had my bedroom in the attic. When my radio came with in 2 foot of the amplifier then I could receive 50 different station. Old cell phone antennas outside of the CAR with out any connections except capacitance between the cell phone and the antenna. Go to so you people that have NO IDEA ABOUT RADIOS!

antennas (author)Mick Gibson2016-08-09

Someone here knows nothing about radios.....

Mick Gibson (author)antennas2016-08-10

No I have a Masters and two time I went back to school and had learned about transistors and ICs. Now what!

I don't know about using a hand mixer, but I am aware of the "attic bedroom coilspring mattress", and the "I had to lug that sucker up three flights of stairs" copper cored radiator. But these had to be physically connected to your radio. And if the radio was a transmitter, FCC people would show up soon enough, for educational purposes.

Topteddy49 (author)2016-07-17

Of course it will work and it wont do any harm to the phone. The coil here will either inductively or capacitive couple (or both) with the internal antenna and act as an external collector of any signal going. I would agree with the post from soakedinvancouver suggesting fiddling with the length and the coil of the wire. Any copper wire will do. It doesn't have to be from a motor winding. Good instructable.

antennas (author)Topteddy492016-08-09

No it won't that's not how antennas work. Not even close. Plus surprise, the antenna is on the outside of the phone. oh my.

PKM (author)2016-07-11

I wondered how signal boosters work, so I looked it up on Google. I found which I think tells you everything you need to know (they don't work at all and may make your reception worse).

If you don't want to take this one guy's word for it (after his double blind experiment), what about the 184 people who gave this signal booster sticker a 1 star review on Amazon?

balsuryana (author)PKM2016-07-11

anyway, Thanks for look my works. i hope you enjoy this

Don't let them get you down man, I think it's cool and demonstrates some good qualities on your behalf that you tried to solve a problem.

Also, annealing the copper wire after making the coils would reduce the internal stress in the wire which resulted from the bending. I don't remember the physics lesson regarding how current flows across a bent wire, but doing so probably decreases the coil's resistance to some degree, even if only by an insignificant amount.

antennas (author)IngenuityAtWork2016-08-09

It only demonstrates he knows nothing about antennas at all. It is not annealed, it is just burned , he is removing the insulation which is not required in an antenna. This does not work. Physics proves it doesn't work.

JayH10 (author)PKM2016-07-18

Checked out your Amazon link. Found it more interesting that NONE of the
suggested "boosters" received more than a 3 star rating....kinda tells
the tale, eh? Also, the author only got ONE more bar! He could have
gotten that by just turning around or holding the phone slightly

Snake oil does nothing but just p***** off the snake.

ThomasK19 (author)PKM2016-07-11

Hehe. That was also my first thought. One of those voodoo devices xD

spark master (author)2016-07-17

sweet, will try it fer sure, you do not need to sand the wire, rf doesn't see it, nor reflect/refract off it. The antenna in a phone is inside a plastic case. It is way thicker and yet the system works well usually.

bravissimo maestro

bodger-bill (author)spark master2016-07-20

This may not be quite true !, by sanding soft wire you are effectively giving it a greater surface area, imagine a cog wheel if you had no teeth on it, it would just be the surface area of the diameter, now cut the teeth and check the exact external surface area ?

antennas (author)bodger-bill2016-08-09

No. It does nothing at all.

Yonatan24 (author)2016-07-17

Common sense tells me that this is fake. Am I wrong?

balsuryana (author)Yonatan242016-07-17

i have test it with my smartphone, and it affect to my signal. When i remove this, my signal is bad again and if i use this again, this increase my signal

btw. thanks for look my works

adelsonline (author)balsuryana2016-07-17

Dear Balsuryana, this device you built seems to work as a extension for the cell phone´s internal antenna, so it could improve the reception in areas with very weak signal. I just couldn´t see any sense in burning the copper wire or putting the device near the SIM cards. As a suggestion you could try to fix the tape to other places or to the phone´s back cover. Thanks for the post.

This. Burning the wire does nothing. How could it?

also, the SIM card has NOTHING to do with the reception or signal, or antennas....they are chip cards that signify to the phone, what carrier to use!!! Sigh.


asadabdul (author)david.roseman2016-08-03

Well, burning the wire certainly do something: remove the insulating varnish from it. But... dunno if that makes anything for this project`s claim.

Yonatan24 (author)adelsonline2016-07-18

Exactly. He/She made an antenna, but from what I know, an antenna needs to be connected to something in order to work. :)

Yonatan24 (author)balsuryana2016-07-17

I didn't know smartphones can experience the "Placebo" effect... :)

Fixem (author)Yonatan242016-07-19

Placebo effect that's it!!!

rbormann (author)Yonatan242016-07-17

Well, add far as i know, a piece of metal, coil or not, have no reason to improve reception, and close to the SIM card, is even somehow senseless, but if someone has a reasonable expansion i would like to know, for sure.

MTspacez (author)2016-07-23

I don't understand how this is supposed to work. Why not just use copper wire instead of taking apart a motor?

BryanB7 (author)2016-07-17

It works on my phone. I also checked for an antenna port could not find one. but my phone antenna dose go by my sim card on the other side of the phone. I would not leave home without my home made antenna. Thanks for the Booster.

balsuryana (author)BryanB72016-07-18

you are welcome. thanks for look my works

BryanB7 (author)balsuryana2016-07-19

It was my pleaser .

OoJ1 (author)2016-07-18

I've done many type signal booster,as long as material you use can receive radio wave,it will increase signal if measurement is right,..

Aristarco (author)2016-07-18

In most phones EXCEPT the iPhone, there is a "small coax-like" antenna connector available, it's called a U.FL connector. They have this connector since the flip-phone era but even when it's at the back, not every phone has easy access to it without removing the back cover. They were used for testing but you could find "external antenna adapters" online. The iPhone has this connector but it's not accessible and it is already connected to the frame antenna. In this picture of an iPhone 5s motherboard:

you can see 3 of these connectors, one at the upper left and other at the left of the SK Hynix processor, another to the left of the processor marked with an orange frame. On the other side:

there's one at the lower right of the processor marked with a yellow frame. Some of them are for Wi-Fi, some for Bluetooth and the rest for the Cellular signal.

JayH10 (author)2016-07-18

Flip phone? Show of hands for those that had one (or even know what it is!) I used to have one.Also had a phone with a very log antenna went into the wall!!! And my contact list was a book in the drawer under the phone! And I actually had to DIAL(insert finger in hole and spin the dial). Not better, just different. But the sound quality of the call WAS much better!!!!!

IlanE1 (author)2016-07-18

Don't outright knock this. For most of the readers, cellular coverage is such that one never needs any help. Perhaps in areas where the signal is truly marginal, the copper coils serve as a kind of focusing repeater [plucking more micro-watts of signal off the air, and re-emitting them in a small area]. If coils placement is lucky, there may be a measurable effect. The burning is hokum, and the location is a matter of luck, rather than proximity to the SIM.

JoeM77 (author)2016-07-17

You can also encrypt your messages by opening the back cover and pouring sand into the phone.

Wow, it works! the universe CH41138 ._.

WannaDuino (author)2016-07-17

or do you work for samsung and try to advertice here


WannaDuino (author)2016-07-17

yes yes and when i stuck ducktape on my celphone, and when i then call my mother in law.

see trips from the stairs. Every time i call her.

qqqqqqqqqqqqqqqqq (author)2016-07-17

What is the reason for burning the centres of the coils?

Although Copper Oxide has been used, historically, for semiconductor diodes, it tends to degrade rapidly.

onion2 (author)2016-07-10

Why it is next the sim card ?

balsuryana (author)onion22016-07-10

to receive signal more fast. and this can boost your signal

M.J3 (author)balsuryana2016-07-17

Sim card doesn't received the signal, the antenna does. Stickers booster don't work, it's always fake !

If this small metal thing increase reception, manufacturer would have use it !!!

If you want to boost the signal, use a better antenna: disconnect the original and plug an extenal antenna.
