May Release - SSR1 Alpha3 (Patreon)

This is the March-May release: SSR1 Alpha3. 

I've made a couple of small changes to the hardware but some substantial improvements to the electronics, software and the documentation. SPI feedback is now incorporated, which represents a big performance improvement. Most importantly though I've written a 16-page accompanying document in which I go into a lot more detail about how to build this device and how to get it working.

Hopefully this will make this device much more accessible to those of you who have been waiting to have a go at building one!

Enjoy!
