This is a follow up post for that one: Hosted Raspberry Pi at PCExtreme – Reinstalled with Raspbian.
I crashed my original OS and asked the kind people at PCExtreme to reinstall my RPi. They did and here is what I did when I received the credentials for the newly...
My Raspberry Pi running Arch Linux ARM hosted by PCExtreme in the Netherlands wasn't reachable anymore after a forced reboot from their side. Most probably I didn't adapt the configuration of the static IP to newer releases of the network configuration system when I installed upgrades on the RPi. The forced...
This blog post is still in the makes, you can, however, already take advantage of the pretty content available so far.
- Install Arch Linux ARM on SD Card (get the image from here)
- Plug SD card into RPi, connect the Camera Module (see this) and power up the RPi
- SSH into...
The Raspberry Pi colocation costs 36 EUR incl. VAT per year, see here. If you spend this amount of money for energy only, it's:
Yearly Energy = 36 EUR/year / 0.27 kWh/EUR * 1000 Wh/kWh = 133 333 Wh / year # to enter it more quickly in your calculator: 36...
If you encounter problems like these:
dhcpcd: eth0: broadcasting for a lease dhcpcd: eth0: offered 192.168.1.64 from 192.168.1.1 dhcpcd: eth0: reject NAK via 192.168.1.1
Online you will find a lot of old threads suggesting things like commenting out the line
require dhcp_server_identifier in the file
dhcpcd.conf. Didn't help in my case.

- Arduino gets piggyback from Raspberry Pi
Simple USB-Serial Connection
You can also simply use a USB port on your Raspberry Pi to connect your Arduino.
Here is a...
Two or three weeks ago my Arch Linux ARM based Raspberry Pi died. At least it wasn't accessible via Ethernet anymore. Here are the syslog details:

Today my Raspberry Pi finally arrived! One of the projects I'm planning to use it for is out-of-band management for PCs.
This blog post will evolve as I'll discover interesting things to do with my RPi.
