Piddler (Project by Markus Dohr and Bernhard Heine, HTL)

Wednesday, December 26th, 2007

hello everyone!

First of all: Maybe the word Piddler puts up the question, what is that?
If you want to know look at the following page 🙂

Here is a short list, which contains the tasks of the school- project “Piddler” :
(adapters: Dohr Markus, Heine Bernhard)

1. The main task is to build a stroboscope. This will be realized by programming a microcontroller (with C),
which actuates LEDs.
Besides the frequency should be displayed on an LCD.
The flash power and the frequency will be varied with a potentiometer.

2. Another important task is the ciruit design. According to point 1 we are trying to
work with a 24V power-supply (and an additional power-supply for the necessary pumps).
This means that there are no special safety measures to consider.

3. Construction: for the frame we are using defined tread elements from the company Bosch.

4. Two pumps are designated, which are in charge of the watercircuit.

All this should happen in the following weeks. We have planned to finish the work at the project in the first week of March.

Deadlines:
Programming: 15th of January
circuit design: 30th of January
Construction: 15th of February
Assembly: till March

best wishes,
Markus Dohr

Good News!: Merry Xmas to Everyone and especially 15 Children in the 3rd World!

Monday, December 24th, 2007

iPressl bought 15 laptops today through the Give One Get One Program of the One Laptop Per Child (OLPC) Foundation. Currently, there are only 5 OLPC laptops in Austria, therby increasing the number of OLPC laptops in Austria times four. High Schools in Vienna and one school in Carinthia, as well as KIMEKI will be and are working with the laptops. I am already envisioning many projects in collaboration with KIMEKI, as well as schools and kindergardens in Austria. The OLPC laptop is an incredible push in technology, it is an open source project and already has incredible cababilites with an endless number of things to come (see also the OLPC Wiki)!

Merry Christmas!

Collaboration with KIMEKI 2008

Saturday, December 22nd, 2007

Things to come! were decided at todays meeting with Erich Kucher, current Vorstand of KIMEKI, in Klagenfurt. Many new ideas were discussed, such as future steps for our project CINEATRIX. A brandnew idea might be the incorporation of MIT’s $100 Laptop into future projects and programs of our collaboration.

2fast4u and the HTL Wolfsberg in Austria

Friday, December 21st, 2007

I am advising 4 HTL Wolfsberg students through the course of their High-School thesis. In pairs of two, they will be working on and optimizing two popular objects that were already built for this years HighSpeedPhotography exhibition 2fast4u.

Students: Andreas Maier, Bernhard Heine, Leopold Stefan, Dohr Markus HTL-Wolfsberg

More news will be posted by the students soon…

Solar Milestone Quietly Announced on Nanosolar Blog

Tuesday, December 18th, 2007

Extracted from NanoSolar Blog

NanoSolar Panel

After five years of product development – including aggressively pipelined science, research and development, manufacturing process development, product testing, manufacturing engineering and tool development, and factory construction – we now have shipped first product and received our first check of product revenue.

We are grateful to everyone who supported us through all these years and the many occasions where there appeared to be mile-high concrete walls in our path; the unusual intensity and creativity of our team deserves all the credit for achieving this major milestone today.

Our product is defining in more ways I can enumerate here but includes:

– the world’s first printed thin-film solar cell in a commercial panel product;

– the world’s first thin-film solar cell with a low-cost back-contact capability;

– the world’s lowest-cost solar panel – which we believe will make us the first solar manufacturer capable of profitably selling solar panels at as little as $.99/Watt;

– the world’s highest-current thin-film solar panel – delivering five times the current of any other thin-film panel on the market today and thus simplifying system deployment;

– an intensely systems-optimized product with the lowest balance-of-system cost of any thin-film panel – due to innovations in design we have included.

Today we are announcing that we have begun shipping panels for freefield deployment in Eastern Germany and that the first Megawatt of our panels will go into a power plant installation there.

As far as the first three of our commercial panels are concerned:

Panel #1 will remain at Nanosolar for exhibit.

Panel #2 can be purchased by you in an auction on eBay starting today.

Panel #3 has been donated to the Tech Museum in San Jose.

[These are obviously not the first three we ever produced – we have produced loads for testing – but these are the first three of what we consider our commercial panels.]

Live Streams – MIT-Austria

Friday, December 14th, 2007

The live streams have been an accompanying feature of MIT-Austria events, such as the 2fast4u High-Speed Photography exhibition, where visitors at the exhibition in Austria could communicate live with students at MIT.

The site at this time was www.redwired.org/tmp/2fast4u and we had 6 feeds running (meaning six cameras!) with 3 booths, where the users could also talk to each other and take snapshots of the different views of the cameras. Screenshots of the feed website can be found here.

At this time there are only two more feeds running: One at MIT, in building 4 in the basement, looking out the windows. The other one sits on a table on the 3rd floor in the Stiftsgymnasium St. Paul in Austria, viewing a former project of the school. The little house can be remotley controlled over the web:
