There’s a feature in most modern BIOSes, which makes it possible to power on a PC if a certain “magic packet” is received on the physical (MAC) address of the PC’s LAN network card.
I have a set of SilverCrest IP20 remote controlled sockets purchased in LIDL.
Remote: SilverCrest 113854 RCT DS1 AAA-A 3726
4x Switches: SilverCrest 113854 RCR DS1 3711-A IP20 FR 3726
These work on 433Mhz radio frequency, so the switches can be controlled using my Raspberry Pi instead of the remote control which came with the set.
In one of the previous posts I have shown how to control the socket’s with pilight and an RF transmitter.
Since the pilight protocol which will be able to control my outlets (quigg_gt9000) is not finished yet, I wrote a simple command which sniffs out the raw codes (with pilight-debug) and a bash script to use send these raw codes to control the outlets (with pilight-send).
At the time of writing this post, the newest device in the Raspberry Pi universe was Pi 3, released on 29th February 2016, boasting a 64bit CPU, an onboard Bluetooth chip, and last but not least: onboard WiFi.
We’ll focus on how to set up WiFi in this post.
I’ve started writing the original version of this tutorial in 2014, and back then I had less experience in managing Linux users, permissions and services, and also the official OS of Raspberry Pi, the Raspbian was a bit different, too. The below how-to is a major re-write of the original, and it’s intended to be configured on a Raspberry Pi 3B+ and Raspbian Stretch Lite (2018-06-27).
It’s a work in progress, so please be warned!
Now, on to the interesting stuff…
Downloading (legal) content using torrents is very convenient, but if you plan to keep the files “seeding” which is the term to allow them to be uploaded back to other users, then you’ll need to keep your computer running 24/7 which won’t be good for your electricity bills. For this reason it’s a nice idea to use a Raspberry Pi as a “torrent server” a.k.a “seedbox” which will run day and night, as it’s power consumption is tiny compared to a laptop, let alone a desktop PC.
We’ll be using Transmission as a torrent client, which can be installed as a “daemon” running in the background all the time on the Raspberry Pi.
The Raspberry Pi is a cheap, little credit-card sized computer, which can be used for a myriad of projects. I’ll show you how to get it up and running, including the necessary peripherials. This guide is aimed on how to set up the Raspberry Pi 2 and 3 with wired ethernet connection.
