About: I love writing, I make video in MY UPLOADED VIDEOS channel in Youtube for my instruction, and i love making something. www.instagram.com/balsuryana

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

Lets make a signal booster!!

For:

  • 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:

  1. Old motors
  2. Clear tape
  3. Scissors
  4. Matchstick / lighter

Its FREE!!!

Step 2: 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

  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

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!

  • 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

  • Turn off your phone
  • Put the signal booster near your simcard

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

Step 7: Finish!

Thanks for look my works.

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!

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.

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.

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.

I wondered how signal boosters work, so I looked it up on Google. I found http://www.andybrain.com/extras/cellphone-antenna-... 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? https://www.amazon.com/Cellular-Innovations--BOOSTER-Universal-Antenna/dp/B00009WCAP/ref=sr_1_5?s=wireless&ie=UTF8&qid=1468241391&sr=1-5&keywords=signal+booster+sticker

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.

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.

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
differently.

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

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.

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 ?
