Stop Those Pesky WiFi’ers… Okay.

One comment

Why would you want to? Well, maybe security? Not me… but if you need to, here’s an “Open Source” hardware project that will auto-tune and do it!

Wave Bubble RF Jammer

So, now you can jam those pesky Wi-Fi users. Riiight! Whatever floats your boat… but, it IS interesting!

“This website details the design and construction Wave Bubble: a self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camoflauging: it is the size of a pack of cigarettes. An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). The battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). Alternately, 3 AAA batteries may also be used. Output power is .1W (high bands) and .3W (low bands). Effective range is approximately 20′ radius with well-tuned antennas. Less so with the internal antennas or poorly matched antennas. Self-tuning is provided via dual PLL, therefore, no spectrum analyzer is necessary to build this jammer and a single Wave Bubble can jam many different frequency bands – unlike any other design currently available! To reconfigure the RF bands, simply plug it into the USB port of your PC and type in the new frequencies when prompted. Multiple frequency ranges can be programmed in, each time the device is power cycled it will advance to the next program in memory. While the documentation here is both accurate and complete (as much as possible), the construction of such a device is still an advanced project. I would not suggest this as even an ‘intermediate’ skill project, considering the large amount of difficult SMT soldering (multiple TSSOP and SOT chips, 0603 RC’s), obscure parts, and equipment necessary to properly construct and debug. This design is not for sale or available as a kit and never will be due to FCC regulations. Please do not ask me to assist you in such matters.

Oh, and did I mention it is also HIGHLY illegal? Hummmm…

Update to the DirCaster Project Already!

Leave a comment

Thanks to Henry L. Ratliff, a listener to our podcast, we now have a fixed DirCaster release with new features! Here’s the ChangeLog:

ChangeLog for Version 0.7a
==================================================
2006-12-25 H. L. Ratliff
. Fixed several PHP Notice errors issued when error level set to ALL
. Patched occasion where single digit day in pubdate sometimes
displayed for example ‘ 1’ instead of ‘ 01’. new function fixDat()
. Substituted RSS title tag value with file name when id3 title value
is empty. stripType() drops the file extension
. Corrected raw ‘&’ in RSS title tag (use ‘&’ instead)
. Fixed variable name error which caused, the logic to produce only
a set number of feeds, not to work. Controlled by $maxFeeds.

The DirCaster Project

Thanks so much to Henry for helping get the bugs fixed, and the new features I talked about wanting on the last podcast included. He rocks! Oh, by the way, DirCaster generated RSS feeds now pass the FeedValidator.org RSS feed tester for iTunes and RSS feeds PERFECTLY!
