DIY a Cell Phone Jammer Kit for Fun

Do you know what is a cell phone jammer kit and do you know how much fun it can bring to you? Let's see a video first.


Geeks can be pranksters . If you’re a small mischevious, a cell phone jammer kit is a must have gag device for the belt. Think of all the pranks you could pull off by blocking radio frequency signals using a jammer, even blocking cell rings from functioning.  Is that interested? Then take read more about cell phone jammer kit on wiki page.

An cell phone jammer kit can be built as a do-it-yourself project as Adafruit’s Wave Bubble, a self-tuning transportable cell phone jammer kit shows. The Wave Bubble calls itself a self-tuning, wide-bandwidth transportable cell phone jammer kit.

Self tuning is by dual phase lock loops which nullify the necessity for a spectrum analyzer. Multiple programmable frequency bands make it work across a range of RFs. Tuned antennas give it a range of 20 feet. Output power is .1W (in high bands) and .3W (in low bands). Three hours of jamming work over dual frequency bands (as used by some cell rings) with a rechargeable internal lithium-ion battery ought to be for your dirty deeds. Or you can get more hours over a single band as used by cordless rings, GPS, Wi-Fi or Bluetooth. All this can be crammed in a palm sized cigarette pack.

The Wave Bubble site backs-up the project with details under Share-Alike so go ahead & make yourself one.  As the site warns, this is advanced stuff asking for lots of circuitry savvy.

Note: Using a cell phone jammer kit to block communication by disrupting the signal is an exclusive right of the authorities. Among other things they are extensively used to prevent remote activation of explosive devices by terrorists. Federal Communications Commission (FCC) rules apply & they take a dim view against illegal use of cell phone jammer kit.
