What the 8 happened?

Sorry all, I really had to get some Z post-hackathon before typing any sort
of sensible text about it. I enjoyed the buzz tremendously and could not
sleep a lot during the event as hacking continued pretty much throughout
both nights.

Results of the ELL-i Bare Metal Hackathon are impressive to boot. All of
the contest entries include a small embedded computer running task-specific
software and electronics while some connect this to a bigger system such as
the Internet.

Contest winner Konsta Hölttä programmed a fully functional software
polyphonic audio synthesizer for STM Discovery F4 from scratch,
winning himself a Saleae Logic Pro 16 analyzer.

First runner up, Ivan Raul and Qinglai Xiao wrote a Gdb remote stub
for ARM Cortex M0 that supports SWD connectivity to the next MCUs in the
system. Special kudos for supporting more than one variety of M0 from the
beginning. Prize for Ivan and Qinglai is Saleae Logic 8.

Second runner up, Tatu Peltola made a direct conversion radio
receiver for Ellduino with very minimal external component count,
winning a Saleae Logic 4. The demo was entertaining and very hacky.

Honourable mentions go to Manik Madhikermi, Jose Granados Vergara
and Andrea Buda for best working system for their network enabled
blood pulse oxymeter and Tuomas Aura, Mohit Sethi and
Sandeep Tamrakar for Config with light & sound for coolest idea.

The hackathon core idea was to hand out very small embedded computer
developer boards to people, see them group spontaneously and try to achieve
any unlimited idea they decide to pursue in the 48 hours time. All of the
devices had an ARM Cortex M family processor with at most tens of kB of RAM.
Some of the boards have network connectivity and making networked devices was
