Epic Hardware Hacking Weekend

Feb

2012

It turned out to be quite an epic weekend of building boards and getting things up and running. It’s good to be back in the groove with my own electronics projects – it’s been far too long that I’ve been away. As a wrap-up to the weekend I thought I’d put together a bit of ...
