The SWA1 Smart WiFi sockets are great cheap WiFi controlled sockets that you can get on Amazon. Not only are they very convenient, but they are eminently hackable. Hackable to the extreme.

Filtering WiFi Noise

I recently needed to connect an ESP8266 board up to an audio control and processing board I was working on. And as you can guess the noise was horrendous. Kind of like when you leave your mobile phone near a radio and someone calls you. Pop, pop, crackle, pop pop...

So, some filtering was in order. In the end I came up with this circuit:

The values can probably be refined somewhat, but I just used components I had lying around.

More ESP8266 Hacking - LOHAS LED

LOHAS LED LampYes, I have hacked another ESP8266-based device. This time it's the LOHAS WiFi Smart LED lightbulb.

What is it with the ESP8266?

Xtensa have pretty much got it made.

But what is it that's so great about the ESP8266 that's got everyone using it?
