Scanimate is the name for an analog computer animation (video synthesizer) system developed from the late 1960s to the 1980s by Computer Image Corporation of Denver, Colorado. It is a form of analogue video synthesizer. The 8 Scanimate systems were used to produce much of the video-based animation seen on television between most of the →
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 →

Replacing SMD components without burning neighboring connectors without hot tweezers Desoldering Techniques One Hit Desoldering Desoldering without hot air How to Solder properly || Through-hole (THT) & Surface-mount (SMD) Sostituzione connettore alimentazione micro usb step by step How to repair bridge →
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 →
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. →
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 →
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 →
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 →
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 →
The powerCON is an electrical connector manufactured by Neutrik for connecting mains power to equipment in a small space (smaller than IEC connector commonly used on PCs). Neutrik powerCON 20 A is a locking 3 conductor equipment AC connector with contacts for line, neutral and pre-mating ground contact. It is a rugged solution that has →
