How to Build a LED LAN Device Counter #piday #raspberrypi @Raspberry_Pi #iLuvPi2

From instructables user zerblatt007:

Do you know how many devices are on your local network? That is what we where wondering at our hackerspace HackBergen.

Yes, there are available programs and Apps to scan your network, but we can also scan with the Raspberry Pi (RPi) and show the result on a set of 7-segment displays.

These look cool, retro, are cheap and can be seen from a distance for you to have a general idea of how many devices are currently operating on your local network in these IoT times.

This build uses 3 modules of 7-segment common Anode LED displays that are controlled by an Atmega328. We use 3 because normal home LANs are C nets with a maximum of 256 devices and I had 3 of these nice 7-segment displays lying around. 🙂
