The PC should see the board as a COMx connected over USB, so the software
(C#/.NET) just has to send some WMI data (CPU load %, Disk usage %, …) to
the serial interface… sounds easy :-)
The software should be a service, so the data can be sent even when nobody
is logged in.
And I would like to
Never underestimate firmware ;)

Thanks Paul, I added another 0805 for the cap and the PCB is now in
production. Time to start writing the software for the pc side, that
shouldn't be too hard.

Hi
Perhaps a couple of SN75468 but the pin outs are different so you will
need a small adapter board. Or just discrete parts, again on an adapter.

You can have a lot of fun with those ring neons.

The link in that stack exchange article is ok. Here is a current one. So my
100pF cap doesn’t agree with their 4700pF...

Some datasheet I read a long time ago had a 1M resistor in series with a
100pF capacitor between shield and signal ground. That is what I have used
ever since as it was the first unequivocal statement on it that I had ever
seen, before or since. See this schematic as an an example
it's a two-layer pcb and a needed only a few vias. It was uncomplicated to
design the pcb. At least its nothing more than daisy-chained
shiftregisters and their outputs are driving the K115IDs and MPSA42s.
the first pcb design directly worked (only the HV-power supply is placed
too tight to
That's a good point, but it I think it is ok because the connector I'm
using is a 614105150721. According to the datasheet it should be a vertical
micro-B USB connector

How many layers does the board have?

Thank you all for the input. I measured two commercial USB to serial
converters I use to upload the firmware to the clocks. One has a connection
from the shield to ground, the other has no connection to ground :-)
I added a 0805 component, so I have all options. I will start with the 33k
Great job, I'm very glad to see my NCH6300HV is a part of your nice design!
