I have setup a network sniffer that i can use to capture packets between two networking devices. I made a YouTube video in which i explain how it works and below you will find both the shell script and python script i used to setup the bridge and dump the packets respectively. The raspberry pi is pl...

I usually connect the ground to a GPIO pin and turn the pin on and off to make the LED turn on and off. How do i go about turning on and off an LED if it is powered through an external battery an...

Luckily you can mute the counter so I won’t be awake at night listening to constant blips. http://jamesdotcom.com/other/gcs.jpg I don’t know if anyone here would be interested but I have made a quick YouTube ...

I had the Raspberry PI running at 1Ghz and found that with no cooling it would run around 52 degrees. With just the heat sink it would run around 47 and with both a h...
