While exploring the different methods of generating some waveform I stumbeled on an old project of mine that has been shelved for almost a year because it would not work no matter what I tried. So I got out, redesigned the pcb, soldered new components and wasted 4 hours tracking down some trace issues. But in the end I had a working DDS function generator based on this simple but effective design: http://www.scienceprog.com/avr-dds-signal-generator-v20/
This is ust a very short overview about my old 400 MHz/64 Mb RAM Laptop computer, that I turned into a serial terminal after usb stopped working and the body-case broke open. Unfortunately I couldn’t find the original layout for the board anymore but it followed the usual max232 schematics anyway.
I wanted another Arduino because I don’t want to dismantle a work-in progress every time I start another one. So I got this NKC electronic manufactured Freeduino Kit from physicalcomputing.at for 22 € + shipping.
I got really lucky with my 555 contest entry this spring because after all the winners claimed their prizes I got an email from chris saying that I will receive the Xilinx SP601 fpga-kit. Wooooohoooooo!
So after some I received the box and wanted to say thanks to all you guys involved and especially Xilinx for giving out such a cool thing.
On a side note: I didn’t know how costly international shipping was until I received the board. 46 € to get a kilo from the US to Europe + 12 € import toll. Really, individual shipping is very expensive. This makes me even more jealous of you US guys with your tons and tons of surplus hardware you have.
Anyway thanks to all of you and I hope there will be a new electronic design contest next year.
