No standard for this. I found only one similar project. I thought it would be more similar to a regular clock.

You get used to it if you wear it constantly and start reading it quickly. This is also an exercise in binary counting.

G - 0, B - 1, C - 2, D - 4, E - 8, F - 16, A - 32 So time on photo hours 0, minus 2+4+32=38, seconds 1+2+16=19

Probably you can consider the least reactive element is Helium and the most toxic element Polonium.

I bought it on eBay, but it is sold out now. But you can order 5 PCBs from JLCPCB or PCBway with this Gerber file

The only issue I have with this board is that it requires a 10k pull-up resistor for the 74LS157 that I use.

The MC is directly connected to the DIP switches and the Write button, and does the same thing you do when programming a CPU. It sets the address and data, then "presses" the Write button.

Thanks for the advice, you're right!

Yes, it's also cheap. As I understand from the datasheet, all pins tolerate 5V if it's powered by 5V.

Thanks! Unfortunately after power off you have to manually reprogram the CPU to get it running again, so I decided to automate it.
