RC square wave generators

The article contains schemes of three non-standard, but simple frequency-controlled RC square wave generators, made on transistors of structure p–n–p and n–p–n. The number of options for rectangular pulse generators, according to the most conservative estimates, is more than one hundred. However, on the pages of periodical… Continue Reading

Meter battery capacity

Meter battery capacity

Most of today's portable electronic devices draw power from the batteries, which have a limited life. Each charging and discharging cycle in small steps helps to demolition and battery "battery holds less". Presented device can measure the energy efficiency of the battery and to determine its consumption.… Continue Reading
