I am not an expert. I also have not read TFA. That said, calling it a 2.4Ghz spectrum analyzer is a bit misleading. Not, that it isn’t a really (really) hard problem to solve! Chances are it’s...

@fdawg4l Indeed, you haven’t RTFA. This article and the original mention the use of a radio module. Namely a CYWM6935 WiFi module, whose RSSI output appears to be used to do the acquisition.

@Johnathan, I gathered that from the code snippet he posted. Again, I’m not an expert, but I believe my theory about it not being 2.4ghz spec an. stands. RSSI means it’s actually demodulating and...

Has anyone else noticed the nice label on the MCU, really simple, i must implement that on my teaching units. such a great idea.

Can anyone explain to me how that is possible? I donno the arduino’s clock speed, since my thing are PIC’s, but according to Nyquist theorem, to acquire a signal, for fidelity purpouses, one need to...

Yeah, I second labels on the micro. Makes sense and avoids expensive mistakes when swapping chips over. What would be pretty clever is to have the programming and USB pins on the chip broken out via an...

Hey all, i’m the one who made this project. Just to address a few things: -I can’t claim complete credit for the chip label idea. Sparkfun does it on the atmegas that they sell, and it seemed like a...
