This sounds great! The site left me a bit confused however. Is it open in respect to software/firmware? Or also the hardware? Can I just build my own with stock components? Something was mentioned about a DIY kit... The WM12 is basically two TW4 modules ... Um, TW4? As an ignoramus I need some introduction please...

Apparently it isn't open source at all, firmware is CC BY-NC-SA 4.0. It appears that the author does not know what open source means.
