STM32 nixie clock My take on nixie tube clock, using STM32G070 with internal RTC and four 74141 as drivers. Clock uses Czechoslovak ZM1082T, but main board can by used with any nixie tubes.

Goal is to create a basic but fully functional phone using an STM32. The project is still in the schematic phase, but is almost complete. Contains the following components: Processor: STM32 -> ...

The NGD digital circuit theory, operation principle and design methodology are established by means of frequency-time diagram and verified by both simulation and experiment. Various arbitrary waveform ...
