Had to admit, the failure of the Beta 9 got to me a little bit. Took me a couple of days to take stock, stand back and think.
After much thinking, about life, being married, kids and generally having to work hard at a day job, remembering about that one time where that bloke ripped you off, Postulating how things can build up and get to you to the point where you just think that getting screwed and having your balls in a vice would be more preferable………..
You can come to yet another epiphany!….Screw it and put the Balls, in a vice.
I present to you……..The precursor to the release candidate for the production version….Err

The BETA 9, Butchery edition.
See those tiny M1.2 screws daintily poking through the two unpopulated header holes right by the SDA and 1V2?
Underneath is a small PCB, somewhat resembling the bit missing on this unfortunate Beta 8 board.
I’ll do the CAD another time, but, essentially what’s happening here
I’ve made a C clamp from a piece of PCB – sitting on the underside of the next PCB
The two tiny M1.2 screws and nuts (enough of the jokes please, it’s not the size that matters, it’s how you use them) screw to the bottom bit of PCB and pull the bottom board towards the Top board, clamping both together in the process.
It works perfectly!
And, finally, to show just how
prescient Lucky I was – Here’s the PCB . The SCL and SDA are perfectly centred on those two [currently unused] header pins.
Obviously, production version will be different, I’ll likley include a number of clamping holes to capture the whole J15 connector
Also, note another bug, the reason for the large red bodge wire….Yeah, Forgot to tie the 3V3 nets together on the PCB!, D’oh!
