Hey so, it's been a while.
After I got my initial prototype I decided to spend some time daily driving it to see if I could identify any issues, so far, nothing wrong, I'm very much liking this with boba u4 silents.
However, there have also been huge issues with getting aluminium and brass stock, not so much here, but for Salvun, who I decided to get the second round of prototypes from, partially because I was having immense difficulty getting good anodisation in Australia (This seems to have been resolved in the meantime but needs further testing, at present I'm waiting until I have all salvun units in hand (Full brass, Full Blue, Black Top, Dark Grey, Gold Base, Gold/Blue/Red/Black 4.5mm alu plates, 2x brass plates remaining)
As of a couple of days ago I got my first Salvun made prototypes for the board and I've got to say I'm very happy with the quality of these, right now I'm just waiting on final production sample PCBs to come in, the parts for these are already at the assembler and I should have those within a week or two.
Regardless, here's the update, here's the pictures
