[Stephen] often finds the need to make his own PCBs at home, and when he got the urge to do some etching recently, he realized that he was fresh out of “Ferret Chloride and Bureaucratic Acid*.” ...

These days, PCB fab houses are just about everywhere, and you can’t go buy a taco without walking past eight of them. Still, some out there still like to etch their PCBs at home. If that sounds like ...

One of the most common issues I see with schematic and PCB layout is crossed wires. For example, the designer has connected the USART peripherals transmit line to the transmit line of the receiving ...

Rigid-Flex PCBs have been used in many modern electronic devices (such as mobile phones, laptops, and wearables, among others), due to their form factor, light weight, and cost-effectiveness.

Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...

Key to the development is the identification, by University of Southampton researchers, that a PCB manufacturing plant has everything needed to make micro-fluidic bio-chemical sensors. Disposable ...
