Thank you, Phil. An EasyEDA file. Perfect!

Have you had an opportunity to take advantage of the JLCPCB/EasyEDA promotion (see below)?

Hi Mike, yes I got them at the reduced rate, but I wasn't aware it was ongoing, that's good!
Meanwhile I added an overlay... it is looks much better than the pic, light reflection from the camera

Oh, yes, that does look nice.

Happy to hear that PCB promotion is good in the UK, too.

I tried the PIC16F876A's kindly donated by Sirius and as expected they work fine in the PIC14, also I found another PCB so for anyone wanting to join in the fun we will have three PIC14 PCBs each with a programmed 876A chip up for grabs FoC
All you need is a ULN2003, some buttons, two-off four-digit 7-seg common cathodes, a 20mhz crystal, and a CH40G module for uploading (mine & Wiggles are powered from the CH40G, no 7805). And a few decoupling caps
Cheers
Phil

No probs RT, sorry too late to edit previous post, the serial USB module is a CH340G (the "3" key is bad on my workshop laptop!)
