Free Elektor Article: Nixie Bargraph Thermometer
https://www.electronics-lab.com/free-elektor-article-nixie-bargraph-thermometer/
Nixie tubes are always fascinating. Nowadays they are mostly used for clock displays, such as the project in the May/June 2016 issue of Elektor. The ‘Nixie’ bargraph tubes for analogue readout in the form of a column of light are less well known. Strictly speaking, they are not Nixie tubes because they do not display […]
Average and RMS voltage
https://www.electronics-lab.com/article/average-rms-voltage/
Introduction In the DC regime, only one definition of the value of a voltage is possible, this value is unambiguous and is determined by the difference between the reference value 0 V and the flat line figure of the DC signal. In the AC regime, however, it can lead to confusion to speak of only […]
