Arduino Nano 33 IoT Modular Nixie Clock with Web UI USB 5V or 12V, Motion, Light, Temperature, Humidity & Pressure Sensors. NTP Sync, Web Interface for changing settings/time & wifi. Project description The story *** Caution the PSU can output high DC voltages, can cause serious injury *** I'm a bit late to the Nixie Party but I finally made it here. This Nixie Clock is a bit different from the others; it runs using an Arduino Nano 33 IoT, has a motion sensor, light sensor, temperature, humidity & barometric pressure sensor and runs from 5V USB or 12V. It has a web interface for changing settings and syncs the time using NTP. Before I got to the final product, I had spent a lot of time making a Shift Register version with transistors and multiplexing, this worked on the breadboard however I got severe ghosting when I made the PCBs. I gave up and switched over to the HV5530 IC which simplifies things. I had to devour a box of Mr Kipling cakes quickly so I could build the...
Just some random circuits that I've built.
