Raspberry Pi Tutorial 45: How to use Screen (Linux)

In More Info, Raspberry Pi | No comment

Screen is a program that allows you to run multiple virtual windows or screens within one terminal login session. Why does this matter? It can be a PITA running multiple PuTTY windows open on your machine while you remote into your Linux computer. Screen eliminates the need for you to run multiple windows – instead you can just run screen.   A benefit more important to me is being able to run programs on your remote computer without needing to keep the ssh session window active. Why get a remote Raspberry Pi to run something if it means your home…

In More Info, Raspberry Pi | No comment

This tutorial brings together what the past two tutorials were working up: turning your Raspberry Pi into a text messaging greeter who welcomes you home from work!

I’m not affiliated with them, and there are other options out there. However it’s easy to get started with Twilio and the…

Raspberry Pi Tutorial 42: Who is Home: Network IP Scanning

In More Info, Raspberry Pi | No comment

This is the first of three tutorials that works on turning your Raspberry Pi into a home greeter bot. The idea is: whenever you return home after work or school your Raspberry Pi sends you a text message welcoming you home. The first step in this project is trying to figure out when you’re home without you having to purchase expensive sensing gear or manually interacting with something.   Smartphones are ubiquitous these days, as is Wifi. Everyone has a smart phone on their home wifi network. This can be taken advantage of by having your Pi scan your home’s…
