Introducing QSPICE: The Next Generation Mixed-Mode Simulation Tool for Advanced Circuit Design
https://www.electronics-lab.com/introducing-qpsice-the-next-generation-mixed-mode-simulation-tool-for-advanced-circuit-design/
The original Simulation Program with Integrated Circuit Emphasis (SPICE) was introduced in 1973. Engineer Mike Engelhardt began developing his version of SPICE a quarter-century after its inception. Fast forward another 25 years and Qorvo has unveiled QSPICE, the company’s latest advancement in mixed-mode SPICE simulation. “Basically, QSPICE is what I would have written 25 years ago […]
Building a Chaotic Oscillator from Common Components
https://www.electronics-lab.com/building-chaotic-oscillator-common-components/
Tim’s Blog writes: A chaotic oscillator is an electronic circuit that can exhibit “chaotic“, nonperiodic behavior. A commonly cited example is Chua’s circuit, but there are many others. I always regarded these as carefully designed, rather academic, examples. So I was a bit surprised to observe apparently chaotic behavior in a completely unrelated experiment. A […]
Simple circuit indicates a low battery
https://www.electronics-lab.com/simple-circuit-indicates-low-battery/
James Wood @ edn.com writes: The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single-sourced integrated […]

Here is a nice PDF document from Intel explaining how integrated circuits are made. From Sand to Circuits – How Intel makes integrated circuits [PDF] – [Link]
Disconnect circuit for 12 volt lead acid and lithium batteries
https://www.electronics-lab.com/50967-2/
KA7OEI designed a circuit that disconnects the battery when it over-discharges. He writes: The avoidance of overcharging is usually pretty easy to avoid: Just use the appropriate charging system – but overdischarge is a bit more difficult, particularly if the battery packs in question don’t have a “protection board” with them. Lead acid batteries (almost) […]
IRis – An Infrared Sensor using Photodiode amplification Circuit
https://www.electronics-lab.com/iris-infrared-sensor-using-photodiode-amplification-circuit/
[devttys0] designed a sensitive IR detector for capturing weak infrared signals. He shared in detail how he designed the circuit, beginning from the basic components, walking through solving the problems and finally ended up with a complete working circuit. Craig Heffner/[devttys0] built this circuit for a friend’s Defcon talk, Blinded by the Light, the talk […]
Iterated-map circuit creates chaos
https://www.electronics-lab.com/iterated-map-circuit-creates-chaos/
Lars Keuninckx @ edn.com writes: The Design Idea circuit shown below is a simple implementation of an iterated unimodal map, reminiscent of the logistic or Verhulst map encountered in the study of nonlinear dynamics. It is useful to show chaotic discrete-time dynamics to students, or as a random number generator. Specifically, the circuit implements: Vk+1 […]
HTML5 Circuit Simulator
https://www.electronics-lab.com/html5-circuit-simulator/
Iain Sharp build this port of online Circuit Simulator based on Paul Falstad’s simulator, however Sharp’s version is built using HTML5 and requires no plugin to run. Think of it like animated Fritzing circuits, with a slew of pre-built circuits and components available for tinkering with. HTML5 Circuit Simulator – [Link]
Making circuit boards with DLP projector
https://www.electronics-lab.com/making-circuit-boards-with-dlp-projector/
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) […]
