So I sold it thinking that I would have preferred one of the earlier versions that had a bit more girth. So if you too want one of the previous versions, I think this pretty much covers what the changes were. If you have any further info about differences I may have missed or other changes that may have happened, then please let me know and I'll add the different variations.

I have redone all the layouts because I could see they could be made slightly smaller, require only a single ground connection and make better use of the space.
