PROP-6502 Propeller Laptop

„This is a Propeller laptop – with a 6502 co-processor and 64K of static RAM!  The Propeller handles all I/O for the 6502 and runs an integrated debugger so you can program the computer.  The Propeller serves as the programmable chipset for this 6502 laptop.  You could use an FPGA in this capacity, but could you easily do this and implement visual debugger software inside an FPGA?  Over the years hardware prototyping has evolved from building-block hardware (TTL) to programmable hardware (PLA’s and FPGA’s).  I believe the Propeller represents the next revolution:  100% software-based virtual hardware – and I built this laptop to prove it!
I’ve always want to design a computer from scratch, but modern CPU’s are too complex, run too fast, and have too many fiddly little pins to be any use in a DIY project.  An older processor like the 6502 is much easier to work with, yet you can still learn about computer architecture from it.  If you think an 8 bit processor is irrelevant because it is old, consider that just because 8 bit technology is out of fashion, does not mean the principles of computing have changed.  These principles, like mathematical concepts such as π and square roots, do not become obsolete just because they are old.“


Trip to asia 2009 – Ich packe meinen Koffer / Rucksack

Knapp 14 Tage vor Abreise sollten langsam die Vorbereitungen losgehen. Da ja alle Flüge bereits lange gebucht waren, müssen nur noch die Sachen des persönlichen Bedarfs geplant werden. Die generelle Frage ob Koffer oder Rucksack ist noch nicht endgültig geklärt. In Singapur und Malaysia braucht man sicherlich keinen Rucksack, aber in Kombodscha wäre ich mir nicht so sicher. Mein bisheriger Favorit ist der „AGADIR 65 MEN“ von Jack Wolfskin oder zumindest ein ähnlicher Rucksack. Das Fassungsvermögen von 65+8 Litern sollte für einen Trip durch warme asiatische Länder ohne Zelt und Isomatte eigentlich grosszügig genug bemessen sein.


Microsoft TAG connects real life with digital world

„Microsoft Tag connects real life with the digital world. Microsoft Tags are small, colorful codes that can be printed, stuck, or displayed just about anywhere. When you snap a Tag with the camera on your internet-enabled phone, additional information or experiences are automatically opened on your phone. There is no fumbling with URLs or texting short codes. Microsoft Tags can make product packages, posters, print-based ads, magazine articles, exhibit signage, billboards, storefronts, business card, or just about anything else, interactive.“


History of the internet

“ „History of the internet“ is an animated documentary explaining the inventions from time-sharing to file-sharing, from arpanet to internet. The clip shows a brief overview of this history and shall animate to go on discovering the history of the internet.
The history is told with help of the PICOL icons, which are also a part of my diploma.
The icons are available for free on in the size 32×32 pixel“

What the hell are you talking about?
We are talking about the „UNIX Time“. The UNIX is a number defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970. You can easily calculate or save times with this number.“

„If you cannot measure it, you cannot improve it.“ — Lord Kelvin

How much does it cost to leave your TV on all day? What about turning your air conditioning 1 degree cooler? Which uses more power every month — your fridge or your dishwasher? Is your household more or less energy efficient than similar homes in your neighborhood?

ioBridge – Remote Control and Monitoring

„We bridge the gap between the virtual world and the real world

Our purpose at ioBridge is to remove all the hurdles involved with connecting DIY projects to the web. This goal has been out of reach for all but the most tech savvy. Controlling or monitoring devices over the web requires proficiency in circuit design, network architecture, scripting languages and website design. Even if all those requirements are met, connectivity issues between devices on a local network and the web render many projects impractical.“

1LT/C – One Laser Tag Per Child


„Here it is, just ummm…. 6ish months late for those of you who saw its debut at ‘The Last HOPE’. For everyone else: 1LT/C is a machine that is capable of running  L.A.S.E.R. Tag for a cost of about $200, providing you get creative and make your own case out of oh… say cardboard? The end result is still well below $300 after you toss in a cheap keyboard+mouse and house everything in a Pelican case as pictured above.“
