Here: http://circuitcellar.com/wiznet2014/rules/ I read:
I hope this is a joke, right?
I’d like to participate in the challenge. WIZnet is promoting use of open source hardware which I appreciate a lot.
But if participants only can submit with proprietary or non-free formats (doc, jpg, gif), I (and others) which use open source software exclusively just won’t participate.
Most open source hardware projects have a code repository and a web page with all the documentation, wouldn’t a couple of links not be enough as contest entry for those?
I ask you kindly to reconsider your accepted formats so that really everyone can participate:
Graphics: PNG, SVG
Documentation: TXT, (LA)TEX, OpenOffice/LibreOffice, PDF, HTML
