Watchdog for Raspberry Pi

Maybe not all of you know that Raspberry Pi has an integrated watchdog timer. This can be really useful, especially when you need to leave your RPi unattended for some time.

For those who doesn't know what is a watchdog, let's see just a small explanation...

Immagine that you made an incredibily wonderful home surveillance system and you are going to use it to check your house during an long trip abroad. After a bunch of days, something goes wrong and your system hangs, so it become unuseful. The only way to solve this problem would be to reboot the system, but you are away from it...

Watchdogs do this reboot for you.

3D printer remote control

Let's keep Whatsapp aside for a while... This time I will offer you a short post about a useful Raspberry Pi application if you own a 3D printer.

3D printers are becoming more and more affordable. Still high in price, but today you can buy them for less than €600. They are not really easy to use, but they can be quite useful in many situations. Also for creating cases for your RPi!
