Friday Art: Circuit Sculptures

Circuits are beautiful in their own way, and a circuit sculpture takes that abstract beauty and makes it into a purposeful art form. Some artists can use circuit wires as the structure of a sculpture, and can try to tell a story with components. Twelve Circuit Sculptures We Can’t Stop Looking At article shows you

Step adjustable resistor box

A decade box is a type of test equipment that can be used to substitute the interchanging of different values of certain passive components when you need adjustable value in electronics laboratory. Decade boxes are made for resistance, capacitance, and inductance. Decade boxes are typically quite expensive devices (compared to other cheap electronics parts). I

8 Strategies to Develop a New Product – Hackster Blog

https://predictabledesigns.com/product-development-strategies/ There are multiple ways for you to develop a new physical product and bring it to market. However, the strategy that is best for you depends on your specific experience, your product, your team, and your finances. Keep in mind that there is no strategy to develop a product that is best for everyone

More measurement on Potato TDR circuit

This is a continuation to my recent potato chip to TDR circuit posting at http://www.epanorama.net/newepa/2018/10/16/potato-chip-to-tdr-circuit/ Here are some measurement results made with high speed oscilloscope (at shortest pulse setting and 50 ohms impedance). Blue measurement with circuit directly connected to scope and yellow wirh 10x scope probe.

Switched-mode power supply tutorials

A switching-mode power supply (SMPS) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required. The main advantage of the switching power supply is greater efficiency than linear regulators. The downside of

With the “Dead Bug” Method, Hobbyists Can Break Through the High-Frequency Barrier – IEEE Spectrum

https://spectrum.ieee.org/geek-life/hands-on/with-the-dead-bug-method-hobbyists-can-break-through-the-highfrequency-barrier PCBs are essential in mass-produced products. They assure almost perfectly repeatable circuits. And PCBs with a good ground plane are essential for high-frequency circuits. But rapid prototyping with PCBs has drawbacks compared with the speed and ease of building a circuit on a breadboard. This article presents one practical alternative to PCB for high-frequency

Potato chip to TDR circuit

A time-domain reflectometer (TDR) is an electronic instrument that uses time-domain reflectometry to characterize and locate faults in metallic cables. I designed a TDR circuit many years ago for easy cable testing with oscilloscope: That circuit was also turned to an electronics kit that is sold by Far Circuits. When getting the original 74AC14 seemed

Supply Chain Security is the Whole Enchilada, But Who’s Willing to Pay for It? — Krebs on Security

https://krebsonsecurity.com/2018/10/supply-chain-security-is-the-whole-enchilada-but-whos-willing-to-pay-for-it/ You can have it fast, cheap, or secure — pick any two. It seems to be possible as long as “secure” isn’t one of your choices. “Our IT industry is inexorably international, and anyone involved in the process can subvert the security of the end product,” Schneier wrote. We don’t often hear about intentional
