Just another question now I am soldering bits together for this IV-6 clock.
I think I might have fried the WeMos, or the first led I put on. I am not sure yet, but the led on the WeMos no longer comes on when plugged in.
There is a resistor (r15) that is between the vcc and C4 that’s not in the build manual anywhere, but think it should go on in the first step.
Do you know what resistance that should be?
Also on the build manual the capacitors that go with the ws2812s only say c8-12 and it should be c8-13.
Compared to nixies there are some strange things on the board for me anyway.
What is the massive resistor at R16 a 0r18(0.18ohm) it’s like 15mm long!!
And my usual supplier of parts in Ireland I use (farnell) doesn’t stock the PC817 that I need 14 of.
Other than this I am enjoying getting all the bits together.

So sometime can you tell me the resistor value at R15 please, or anyone else who might know from the pictures?
( search IV-3a IV-6 in the search box to see the thread of the boards built)
Hope everyone enjoys there few days off!

... the Nixie Cloxk PRISM Z566M is ready.
Many thanks to Ian and Ty for your support to make it so.

Wow, nice!

Would you contribute the PCB design files back so I can make it available to others?

Did you make any changes to the Firware, or is that the next part of the journey? At the moment, I am involved on other projects, but for sure the large tube firmware is due for an update. I'll be doing it shortly. I have made many many many improvements to the DA2000 firmware which I shall port forward to the Prism when time allows. Mostly it is to do with making the code more modular and maintainable.

I have flipped the PCB for the latest version of the IN-18 clock, (components all on the bottom) and am working on tidying it up a bit. It is in the repo if you are interested.

Hi Ian,

I think we should clean the layout again and edit it cleanly so that this PCB also meets our requirements.
Do we actually need the RTC? I work without RTC anyway and it works very well with WiFi.

I have changed the order and the colors of the backlight LEDs.

I still have this task. I'll take a look at the result.

You're making the incorrect assumption that all users would at all times have WiFi (and Internet) available.
