[RPi] Measuring RPi Zero USB Network Speed with iperf

Sun, 27 Dec 2015 19:24:30 +0000

As I saw Jeff Geerlings Website and his iperf Benchmarks of different RPis link, I wondered how the RPi Zero would perform by using the USB Virtual Ethernet Interface on my Windows 7 x64 PC.

So I got the latest iperf 2 Version (iPerf 2.0.5-3) from the iperf Website at https://iperf.fr/iperf-download.php, installed iperf from the Raspbian Jessie Packages and launched the iperf Server on my Windows 7 x64 PC via iperf -s. The PC was attached to an Gigabit Switch via an Gigabit Ethernet Interface - so no bottleneck here.

[RPi] The cheapest Raspberry Pi Cluster Ever Made

As soon as the Pi Zero came out, I started on thinking about Clusters again. I wanted to create an big - but at the same time, cheap cluster.
Yes, an Pi Zero is not nearly as fast, as an RPi 2. And yes, there are some problems with this idea - especially about the fact, that the Pi Zero is not as common as an - say - RPi Modell B v. 2.0 - but - as this is more about science and trying to just “do it” - I tried it anyway.

[RaspPi] Multiboot with BerryBoot

If you start using Raspberry Pis, you will run out of Sdcards rather quickly. Reason for this is, there are so many awesome Distros you would like to use - that you are becoming something like an Discjokey for Sdcards: An awful load of sdcards with just some 100 MBs of distros - spread all over your desk. And while sdcards are somehow cheaper than they used to be - today - it is still an awful waste of money.

Raspberry Pi Con "Pi and More"

At the 23. of August 2012, the University of Trier held the first Raspberry Pi Convention in Germany. It was a little, but awesome gig with about 30 IT Students and other interested people.

The main idea was to rise the awareness for the new microcomputer, called “Raspberry Pi” which combines an 700 MHz ARM Processor, 512 MB of RAM, Full HDMI Output, Audio, Ethernet and USB into an very small and affordable package (about 35 US Dollar). With this microcomputer, and its General Purpose Input and Outputs (GPIO), pupils can actually have a “hands-on” (in) physical computing. That means: Connecting software (i.e. Python, Perl, C programs) with the real world. For example: Controlling LEDs, driving motors or even react on buttons, attached to the GPIO port. Combining these possibilities into a small and affordable package started a big hype about this little computer, long before it was even available to the public.
