DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!
Please make sure you are logged in for at least 2 hours
to make sure your IP is added into the firewall whitelist, thanks :)

I added in 2 more caps on VCC pins of the DAC since they are in stupid places.. Digital & analouge ended up mixed up as a result of it all.. but All likely better router than on the Falcon anyway.


EDIT:

PCB view...

I've ordered 10 PCBs and paid for UPS delivery.. Since the 1772 boards only went into production this morning, I have asked if those can be sent with the video boards so I hope to get both quicker then... £25 a go is a lot for UPS... but I should get the boards in a weeks time.. not 1-2months...

:D - Looks like you are building up quite a set of boards that I need Exxos :)

Put me down for the 1772 buffer board and this one.

EDIT: just need to think of a few other things to add from your wed shop to add to that order :)

Same for me, ready for when I get it fixed :roll:

Then time to print some more supports.
If it ain't broke, test it to Destruction.

Yes :) When every chip on the board has a patch PCB on it, then our work is done! :lol:

Agreed. I think we might have gone too far if we start putting patch boards on top of patch boards. :)

Hopefully the boards will come in a day or 2... What I will do is try to make one up for testing before anything else. No use you guys buying the chip and soldering it if the thing doesn't work ;)
