Hackaday Munich: Hot Irons and Crunching Compilers

We're frantically working on the most awesome of plans for the daytime hacking event on Thursday, November 13th.

Because we are limited on time and tools it will be pretty hard to have some from-scratch hardware builds (we're afraid theyd get started but never be finished). But what we are excited about is bringing some interesting hardware to use for a few sets of contests. For instance, a reverse engineering contest, a firmware development contest, a machine learning contest, and an efficiency contest.

What do you think about these themes? What would you add to make the day really spectacular? Do you have any suggestions on the type of hardware to use for each theme?

Thanks for your help brain-storming this!
