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...

Have an old cell phone laying around? Don’t know what to do with it? What if I told you that you could turn that old cell phone into a smartwatch! What I’d like to do for this crazy/ambitions project is turn an old cell phone into a smartwatch. So obviously an old cell phone is...

by Clemens Valens @ elektormagazine.com: The new PIC32MM family, currently Microchip’s lowest power 32-bit PIC32 family, features sleep modes down to as little as 500 nA. Filling the gap between the PIC24F XLP and PIC32MX families, the new family also offers so-called core...

Sanket Gupta pointed us to his latest article, on how to select an inductor and discuss about the various types of them. Inductors are two-terminal components used for filtering, timing and power electronics applications. They store energy in the form of magnetic fields as long as a...

ArduCAM has introduced a tiny Raspberry Pi compatible module based on Broadcom’s BCM2835 Processor, the same chip found in the original Raspberry Pis A, B, B+ and Zero. This module is tiny, measuring only 24 x 24mm and it is compatible with all of the software that makes...

Vasily Ivanenko made a VXO-based synthesizer: To make a VXO to mix with a ~7 MHz VCO, you’ll need a crystal that is higher in frequency than the highest frequency you want to synthesize. Some rummaging revealed a bag of 21.4773 MHz crystals that I could divide by 3 to garner 7.159...
Continue ReadingThe future of IC design
R Colin Johnson @ edn.com discuss about the future of IC design and the different technologies that can extend Moore Law. Such technologies include 3D memories, superconducting, quantum, neuromorphic and photonic mixed-signal devices. To celebrate 60 years of EDN, we’re looking...
