Nuri ERGİNER managed to create his own PCBs using a DLP projector and photo-resist dry film. Every Maker like me dream a PCB printer which can quickly and precisely convert our electronic idea into a psychical circuit board. I know there are plenty of project going on the subject. (see the end of the article) […]
Nixie Tube Energy Meter
https://www.electronics-lab.com/46760-2/
John Whittington decided to build a Nixie tube energy meter to measure his house power consumption. An Arduino would be the microcontroller but I wanted the meter to provide some form of data stream for a web based energy history. To make it an IoT, I a paired ESP8266 with it. I used both together […]
