[RPi] The cheapest Raspberry Pi Cluster Ever Made

Sat, 26 Dec 2015 20:13:03 +0000

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.

[iPAQ] Building Serial Console for iPAQ 3600 to Access Cisco Equipment

Tue, 16 Mar 2010 10:50:30 +0000

After I got the iPAQ 3660 working again, I wanted to use it as Serial Console to Work on the Cisco Equipment “on the road”. To achieve that, we need two or three things:

1.) An special connector Cable to attach the Serial Console of the iPAQ with an RS232 Connector / the Cisco Rollover Cable 2.) An Terminal Software. I did choose vxHpcPlus for that ( http://www.cam.com/vxhpcplus.html ) 3.) Something that makes it possible to use Landscape Mode so that you can read the Console Output more easily: NYDITOT Virtual Display, Version 5.02 ( http://www.nyditot.com/Products.asp )

[pRoToTyPe] iGPS-M Pro USB to Serial

Mon, 15 Mar 2010 17:22:42 +0000

As I wanted an better GPS Mouse for the pRoToTyPe, I did buy an iGPS M Pro USB Mouse ( http://www.transystem.com.tw/products/index_detail.php?mcat_no=2&cat_no=32&pno=10&ver=en ). I was certain that I could resolder it to Serial and use it on the Fonera Router. And thats how I did it: I did open up the Case, which was very easy, just unsnap it. You will find an socket were 4 wires do run out: Black (GND), Red (5V+), White (USB Data) and Green (USB Data) - I did cut these Wires and soldered them to an 8 Wire Cable. From the other 4 left Wires I did use only two: Under the Metal Shielding of the Mouse you will find an TX and an RX Solder Point - these are RS232 Connection Points. I did just pry open a bit of the shielding to run two wires into it, soldered it onto the points and did close the casing again. On the other end of the cable, I did solder on an RS232 Connector, Female. I did use the pRoToTyPe scheme with Phantom Power for that. Additionally, I did wire up Power and Ground a second Time to an USB Connector as well as the USB Datalines. So I have one RS232 Socket and one USB Connector and can use the Mouse for both occasions.
