Paper-Dino

DE: Seit diesem Jahr arbeiten wir an einem Update für das Fritzing StarterKit. Wir haben viel positives Feedback zu unserem Kit bekommen und haben in unseren Workshops und im universitären Feld viel dazu gelernt. Die Erkenntnisse sollen alle in das neue Kit einfließen. Vor allem soll das Kit mehr projektorientiert und zu einem gewissen Teil mehr spielerisch sein. Unter anderem wird es kleine Papiermodelle geben, um Komponenten gleich einen Anwendungsvorschlag mitzuliefern. Hier ein kleiner Vorgeschmack.

EN: Since this year we are working on an update for the new Fritzing StarterKit. We had a lot of positive feedback about the old one and learned a lot in our workshops and in courses at the universities. Those experiences will go into the new Kit, which will become more project based and playful. E. g. we will have paper models to provide a little use case for electronic components.

Welcome Amin (belated)

Amin at Fritzing

DE: Heute möchte ich Amin vorstellen. Seit dem Herbst letzen Jahres kümmert er sich um die Operations bei Fritzing. Geboren ist Amin in Tunesien, einem liebenswürdigen und sonnigen Land am Mittelmeer.

Mit sechs Jahren war es ein LEGO-Flughafen der Amins technisches Interesse weckte. Später, nach seinem Studium des Umwelt- und Ressourcen-Managements in Cottbus (Schwerpunkt Solarenergie und Energieökonomie), gründete er sein eigenes Unternehmen (optimalabs.de) und sammelte wichtige Erfahrungen, die er jetzt in die Arbeit bei Fritzing einbringt.

Nebenbei stellt Amin zurzeit seinen Prusa i3 3D Drucker und einen Tricopter fertig. An den Wochenenden arbeitet er an seinem open energy monitor project.

Um zu beschreiben, was Amin für ein Typ ist, könnte man sagen, dass er – neben Lebenserhaltungssystemen natürlich – vor allem Sonnenmilch, eine Hängematte und einen Kasten Club Mate mit auf eine Reise zum Mars nehmen würde.

Willkommen nachträglich, Mr. Amin!

EN: Today, I like to introduce Amin to you. Since autumn he takes care for all the operations at Fritzing. He was born in Tunisia, a lovely and sunny country on the Mediterranean.

When he was six years old a LEGO airport generates his interest in technology. Later, after his studies of Environmental and Resource Management at the Technical University in Cottbus (focus on solar energy and energy economics) he founded his own company (optimalabs.de). The experiences he made are now coming into the daily work at Fritzing.

By the way, he is finishing his Prusa i3 3D printer and his Tricopter. On weekends, Amin is working on variation of the open energy monitor project.

To describe, what kind of guy Amin is we can say that he would take sun cream, a hammock and a box of club mate on a voyage to the mars (beside life support of course).

Belated welcome Amin!

Still Using OS X 10.5?

Qt, the GUI framework underlying Fritzing, has recently released their next generation framework (Qt 5.0). The new framework only supports OS X 10.6 and up, and does not support the Power PC architecture. We are contemplating a move to the new framework, and wondered how many OS X 10.5 and/or Power PC Fritzing users would be left behind. Please let us know.

Cheers,

– Your Fritzing Team.

a little something for the new year

2013 rings in a new Fritzing autorouter. Here are the before-and-after pictures:

The upper image is the Timer example using the old autorouter (version 0.7.10) followed by a Design Rules Check (DRC). The lower image is the same example using the new autorouter (version 0.7.11) again followed by a DRC. The old autorouter was unable to fully route the board, and the DRC found overlaps around the jumpers the autorouter placed. The new autorouter completely routed the board and the DRC found no overlaps.

For the cognoscenti out there, the new version is an A* maze router with rip-up-and-reroute. In practice (and compared with the old autorouter) this means:

  • The new router does not have trouble with diagonals.
  • The new router does not limit the search in the same way as the old router, so it finds routes that the old router missed.
  • After running the new autorouter, the DRC will usually not complain--or at least will only complain a little.
  • In schematic view, traces from different nets no longer overlap lengthwise (well, much less frequently than before).
  • In schematic view, if a connection can't be routed directly, the autorouter will try to place net labels.
  • No more red dots (unconnected zero-length traces)
  • Routing is not optimal--there are lots of unnecessary zig-zags--so you will want to do some manual rerouting after the autorouter finishes. We'll be working on this going forward.
  • The new router is much slower than the old one (can't win 'em all...).

As an extra holiday bonus–and because the DRC and autorouter no longer depend on straight lines–curvy wires are now enabled in PCB and schematic view. Here is a hand-routed example (at least for now, the autorouter can only use straight lines):

Happy 2013,
