<div style>- Generally, I think a Logic analyzer project would be great as it is a good 'entry drug'. Also should be fairly simple (could have some local RAM as temporary storage and send back to host machine for display)</div>
<div style>- Since we have security interested people: maybe implementing some brute-force symmetric encryption algorithm cracker to see how it performs (probably not that fast with an entry level board with slow clock, but at multiple 'processes' can run in parallel).</div>
<div style>- Bitcoin generation.</div><div style>- Maybe some FFT stuff ? While this might be the primary domain for signal processors, it might be a good way to explore parallelism.</div><div style>- I personally like to have something to generate some frame-buffer PWMed to a LED board ( what I do here in software on non-realtime Linux RPi <a href="http://www.youtube.com/watch?v=2FCyhuT7fIE">http://www.youtube.com/watch?v=2FCyhuT7fIE</a> ). Ben Kochie and I were thinking about assembling a bigger board for Noisebridge.</div>

<br></div><div>If possible, I'd recommend getting a slightly more featureful board though, especially for educational purposes. I like the KNJN.com boards. Their "Saxo" board includes USB 2.0 (via a microcontroller you can choose to program or not) and a clock source. It's a little more expensive at $60, but still in the same ballpark:</div>
