I really love your blog (for this, 24C3 links, etc. etc. you mad scener you.)

But I don't get it about running UDP only on a capture the flag network (aside, I assume, from the unplanned session cutoff thing.) Is it that one only gets one sort and number of UDP port (say) 80, hence very similar circumstances for all players (depending on what the user session ignores; WASD or packets)?

I can definately recommend the fpga4fun shop (http://www.knjn.com/). I bought the Xylo-L and it is a really well thought out product, lots of example projects & source are provided and all the tools you will need to program the FPGA / ARM core (only drawback is windows only :P). They even managed a JTAG over USB solution for downloading files / debugging of ARM core.

dpyatkov – I feel your pain. I think Altera doesn’t even know how a lot of their blocks work! The cores on http://www.opencores.org are usually pretty easy to work with (I used an i2c core once, and it was a snap . . . anything with a wishbone interface really is). I think they even have FFT cores as well.

twistedsymphony – I design my own processors in my free time occasionally, and I’ve been really pleased with one of the XSA-3S1000 boards from http://xess.com/prod035.php3 – It’s only like $200, and you can program it with a parallel port, so you don’t need an expensive JTAG programmer.

http://fpga4fun.com is indeed a good starting place and Altera DE1 development board can't be beaten in price/features. opencores.org is a great place taht's useful when you already know how to put A and B together.

As part of the group (well actually, exactly half) that designed the real-time speech pitch shifter mentioned above, I can tell you that complicated audio signal processing on these CycloneII FPGAs is a headache. In fact, (for a license fee) Altera provides you with a ‘megafunction wizard’ in Quartus which can generate cool things like an n-point FFT block. However, like all things Altera, the documentation on these blocks is insufficient to quickly integrate in to your project. If anyone figures out how to use the Altera FFT block please let us know!

We use the Altera DE2 boards as well at the University of Michigan in our ENGR 100 class. The idea is to design some sort of music synthesizer with an FPGA. Things got really interesting when one group made a Windows 95 interface clone with a music composer on this FPGA.

The University of Florida has a similar class. You can check out their projects by visiting: http://www.add.ece.ufl.edu/4914/groups_fa07.html . As of now final reports are not posted, but judging is today so complete information should be available in the next couple of days.

lol, i've been planning on doing something similar to the real time spectrograph for quite some time now for audio, except using a lcd display (i swear hack-a-day has telepathic abilities :P)

#1, http://www.opencores.org/ is another great website for FPGA stuff. they have a ton of open source cores written in verilog/vhdl.

I'd love to learn more about FPGAs, I've never used one but I see them used in lots of cool projects and they seem like quite powerful tools. I see http://fpga4fun.com referenced a lot and it seems like a great resource.

Does anyone have any other resources, or maybe a good project tutorial for getting started with FPGAs?
