We are launching a new celebration around Open Source Hardware called Hardware Freedom Day and which will be celebrated on April 20, 2013 (Saturday). We just launched registration and will be sending an event kit (t-shirts, banners, posters, stickers, balloons, etc) free of charge to all the teams who register before March 15, 2013.
Need ideas for your event? You can always subscribe to our mailing list and see what others are doing. We also have an IRC channel on freenode (#hfd) for instant communication. Also please help us to make this event as big as SFD by using our banners and countdown on your website. Feel free to localize these artworks (all released under a CC-BY license) to your language and don't forget to share your files on the HFD wiki for others. Happy HFD!
