Just download 8 GB and you are set...

Hey, Xilinx. Thanks for giving out your FPGA development environment for free (as in beer) and all... but seriously WTF: Since I downloaded it the last time (about a year ago), the size of the download increased from 4GB to 8GB?! Moores law in full effect?

(note: I still have only 2MBit DSL around here)

Furthermore: They send you a (uncompressed) .tar, which includes xz-compressed .zip archives.

$ tar tf Xilinx_ISE_DS_14.2_P.28xd.3.0.tar

Cobalt RaQ3 Frontpanel

To replace my current network router, I'm planning to maybe put a Raspberry Pi in the case of a Cobalt RaQ I have standing around since half a eternity.

Don't ask me why, but I spent way too much time (~8 hours) chasing the pinout of the RaQ and putting the awful lot of pins to a Arduino I often use for prototyping. Now I can write to the LCD, monitor button presses and let the LED blink. Because that's the most important thing for a router to do, in a closed network-rack, in the cellar, where the central heating is sitting. And none ever goes to look. Enough for today, I'll most likely put it back in the box I got it from, so that the project can be continued 2014 :-(.

Code is at github.
