Cell phone signal detection part 5 – learning from RF Rockstars

Posted by on Mar 16, 2012 in Blog, Etc | 3 Comments

This is a placeholder post, I am going to add to this brief post (graphs! math! antennas!) in the next day or so. So check back!

I did want to report that I got a small mention in MAKE blog which was SUPER COOL.

Last week, I visited GigaHertz LLC in Pittsburgh. They have been schooling me in the world of RF, and in many ways, encouraging me to keep going in a field that is occasionally kicking my ass. Luckily, I have no ego 😉

I’ve also been learning a ton from Ed Nisley Tuesday nights at an electronics group meeting. He knows a lot about RF and is one of the quoted “naysayers” in one of my previous posts. Turns out, he was right. My first PCB spin was embarrassingly noisy. But…moving forward, I’m waiting now for the next 2 spins to return.

I also have emailing a little with Noah Shibley, who did a similar project a few years ago. I really love how the Engineering-maker community is so willing to share information.

OK- more later…

    That sounds like a really fun trip! I’ll definitely be checking back on this post for updates. I’m especially interested in the math side of things on this one.

    Hi Falldeaf,
    I didn’t do a whole lot of math in my post, sorry. Just the high pass filter….
