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 […]

Energy Wristband monitors energy usage on home
https://www.electronics-lab.com/energy-wristband-monitors-energy-usage-on-home/
by Matt Venn: A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a ‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4. Energy Wristband monitors […]
