Well, this sure is a surprise announcement, at least for me. Blackmagic Design have today announced their 3G-SDI Arduino Shield, allowing you to control your Blackmagic cameras from your own Arduino based DIY projects.
For those who’ve never come across the Arduino before, see here, here, here, here and here. I’ll wait, but there’s plenty more about it here on DIYP if you require some further reading. Basically, they’re a bit like a Raspberry Pi, but simpler and geared more towards hardware connectivity and rapid prototyping, than software development.
