CMOS Milliseconds Clock 

:-) The front of the displays are black so the decision was sorta made for me. Black isn't the best soldermask colour for trouble shooting though.

David Watts What troubles? It’ll be grand.

Ah, I always wondered if there was a way. Smart. I have a full license now but I think it is through Fusion 360 and I am not sure if that is the same, so I will keep plugging away at KiCad.

@@DavidWatts It works because the size restriction is based on coordinates. If you want a board that's 150mm wide, you populate the 'default outline' then select everything, including the outline, and shift it so that the initial origin point of the outline, which was at 0,0, is at -50,0. Then you extend the right board edge from its new +50 x coordinate out to +100, thereby giving a total of 150mm (-50 to +100). I have no experience with the Autodesk Fusion integrated versions. Despite having 'written the book on Eagle' (www.amazon.com/gp/aw/d/1260019195/ref=tmm_pap_title_0) I now only design PCBs for my own use and for charities and 'not for profit' groups. The Autodesk licensing costs render that impossible on a pension - much as I would like to make use of the 3D integration.

Interesting, I have some purple boards from PCBWay coming, looking forward to finding out.

That's where the fun is.

@@DavidWatts Missed third place of millisecond accuracy! They called Centisecond accuracy!

If it works first time I will send you one.

@@DavidWatts hahaha...sounds like a win win there?! 👍🏻

Cool, Aisler look pretty good and not that pricing considering it is the EU. Sadly they only have a green soldermask.

@@DavidWatts yeah there are limited options. I have also found they leave annoying board dags on the edges where they route it out from the panel. A small annoyance. I have also found the solder mask is not always applied evenly which again is not a huge deal, it works lol. When order 4 layer boards I have actually found them cheaper than China if you are after an insured delivery (which is a must for me when you are paying £40 per board and not their cheap $2 who cares price!

Yeah I saw quick a few of those all in one displays but driving the select pin for each digit would add some extra complications. Really just disabling the display on the other 4026s and only letting one through but it was enough to frazzle my brain.

I stole those decimal points as silkscreen to put on the actual board surface. The ones in the cutouts where the digits go are just symbolic. Shorting the D+ and D- was supported by the USB spec last time I read it, 500mA on USB1.1 or maybe 2.0.

There is no software, it is just logic chips. No idea if the PCB will work yet.

I think I hate it about as much as any new software I try, all my previous experience is still applicable here. It isn't like learning a new programming language, I know most of the rules, just not all the buttons to press. I doubt I will ditch Eagle completely but KiCad is pretty darn good.
