There was still the mistake with the not working blank input in the last version. And I did not like that. Specially if looking for testing Tindie with this. So I did some rework on the PCB layout. Now I do think I did fixed that issue. Additional I did change the layout in a way to be inside more Manufacturer's specs. In rev1 I use 5mil Traces/Spaces with 12mil drills. No it is 6Mil/16mil with 13mil drills nad is now again producable by OSHpark (with was important for me to get cheaper and faster Prototypes in low quantity - 1,55$/3PCBs ). To get that I did throw out some unnecessary components and changed the mosfet package to SOT-723. Boards are ordered and should be arrive soon. Here are some renders:

How could it be awesomer ? :-D

Thanks. ...mh maybe RBG would be awesomer or a total overkill.

total overkill is awesome! Now I want RGB ones!

I don't think a RGB version is useful...

@davedarko the PIC doesn't have enough pins for that, in the current system...

  Are you sure? yes | no

and now guess what I did with eagle yesterday... a RGB version is ~20% ready. But there is still a major porblem: PCB Space! 

When this gets to a showable result I will publish it in a extra project.

@Yann Guidon / YGDES. A RGB Version would be a total redesign with different Controller.
After a first look PIC16F1512 or PIC16F723A do look suitable. The RGB
feature is not realy usable if using the TIL311 style interface, but if
controlling it via i2c and/or UART additional color information could be
sent. 
And yes a RBG version would be total overkill and in most cases not  so usefull. But beside that it could be fun to build it.

  Are you sure? yes | no

It's your idea, just do what you like :-)

But I keep liking your implementation and wish I had some dozens for my prototypes ;-)

  Are you sure? yes | no

@Yann Guidon / YGDES - sometimes it's not about being useful :)
