Electronics circuits prototyping

Electronics prototyping is an important part of electronics device development. Prototyping means to build and test an early version of) an electronic circuit. Prototyping your product is all about learning. Each time you create a prototype version you will, or should, learn something new. Start with the most simple, low cost way to prototype your

Signal processing tips from Hackaday

Signal processing is an electrical engineering subfield that focuses on analysing, modifying and synthesizing signals such as sound, images and biological measurements. Electronic signal processing was first revolutionized by the MOSFET and then single-chip digital signal processor (DSP). Digital signal processing is the processing of digitized discrete-time sampled signals. Processing is done by general-purpose computers

Cheap DDS Function Generator

Years ago you had to either build your own signal generator or buy usually a quite expensive signal generator. Lately there has been a push for very cheap ($15-25) digital function generator kits available from China. I wrote about some interesting function generator devices few years ago, and here is a closer look to one

Circuit board manufacturing

One of the key concepts in electronics is the printed circuit board (PCB). A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks. Simplest PCBs have only insulation board with copper traces on one side. More complicated PCB is sort of like a layer cake or lasagna- there
