I’ve got virtual circuits on the mind lately. There are a myriad of tools out there that I could pick up to satisfy this compulsion. But the one I’m reaching for is Minecraft. I know what you’re ...

The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...

Often, it becomes necessary to interface an existing or new 5V AVR / PIC / MCU project to new devices that use 3.3V logic, like memory cards, sim cards, etc. Described here is a circuit that converts ...

A couple of weeks ago, I wrote an article about a digital and analog circuit simulator called ksimus. One of my readers asked what the difference was between ksimus and ktechlab so I thought I'd take ...

Elektor introduced a clever seat belt reminder circuit built with simple logic to trigger a flashing warning light.
