At some point you’ve decided that you’re going to sell your wireless product (or any product with a clock that operates above 8kHz) in the United States. Good luck! You’re going to have to go through the FCC to get listed on the FCC OET EAS (Office of Engineering and Technology, Equipment Authorization System). Well… maybe.
As with everything FCC related, it’s very complicated, there are TLAs and confusing terms everywhere, and it will take you a lot longer than you’d like to figure out what it means for you. Whether you suffer through this, breeze by without a hitch, or never plan to subject yourself to this process, the FCC dance is an entertaining story so let’s dive in!

Inspired by the detonator in the Captain America: The First Avenger movie, [Jon] modified a normal Zippo lighter to activate a relay on a receiver module. His instructables shows how to create such a device by adjusting the insert in such a way that if someone flipped it open, all they would see would be a flint wheel, flint, wick, and all that stuff; nothing would be abnormal. In order to do this, the components would have to be perfectly concealed.
To acquire a remote signal, [Jon] used the whole metal case as an antenna instead of replacing the wick with one. An antenna pin on an RF module was attached to the insert to get the necessary effect. The flint wheel was then turned into a button and a notification LED was installed. Once the code was uploaded and a receiver module was fashioned together, the end product produced a flash of sparks on the other end.
This hack was made for educational use, and is only meant for demonstration purposes.

If you’re one of the hordes whose Xbox 360 died the fiery death associated with the RRoD you may be wondering what to do with that multi-hundred dollar door stop you’re left with. Why not salvage the parts for other uses? If you’ve ever wanted to use your wireless controller with a computer here’s a way to pull out the RF module and reuse it.
The concept is simple enough, there’s a daughter-board in the Xbox 360 which hosts the RF module for wireless controller connectivity. Once you extract it from the carcass of the beast, you just need to find a way to read and push the data to your computer. Any USB enabled microcontroller will do, in this case an Arduino nano was chosen for the task. A bit of level converting was necessary to interface with the device, but nothing too involved.
It sounds like at first there was an issue with syncing a controller with the hacked module, but as you can see in the clip after the break that problem has been solved.
