This is a throw-together project using junk box parts that can be useful whenever an interesting-looking waveform is needed for a demonstration or for the beginnings of a video test generator or curve tracer.
Alternative Uses of Packaging in Electronics

In an era of collapsing economies, waning affluence, and too much garbage amid scarcity, a characteristic that is part of the engineering character - resourcefulness - is due to come back in vogue, as we are challenged to optimize the use of limited resources.
The Shape of Electronics Expertise
Dennis Feucht 9/11/2017 2 comments
As we progress in our acquisition of electronics skills, we occasionally reflect on the “shape” that our knowledge and skills are taking. This article is an overview of basic decisions that “sculpt” our know-how and some of the consequences of the shape of it.
Common-Base Bypassing and How It Affects CB Frequency Response
Dennis Feucht 7/8/2016 3 comments
The common-base (CB) BJT configuration is the second stage of cascode amplifiers. It is useful as a voltage translator to the high side of an amplifier with a large voltage range. This article addresses the question of how the RB, CB combination at the base node affects the frequency response.
The following will familiarize you with the important points of the Formula E race and the images are of the Venturi Team drivers and the car that all teams are using
In Part 1, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, and the gain of the transresistance amplifier circuit, shown repeated below, was derived. In this Part 2 we look at the consequences.
While visiting the Space Tech Expo in May in Pasadena, CA, I came across a group of companies displaying their technical achievements and solutions for Small Satellites known as CubeSats
A supercapacitor boost technology called S-CAP BOOST designed for backup and peak power solutions to industrial and medical applications. This technology is based on the latest supercapacitor technology and combined with intelligent control and monitoring
DC-DC converters operate at all power levels and complexities. At some low levels it can make sense to design and ‘make it yourself,’ but at higher powers, a pre-assembled module becomes more cost-effective. New ‘micromodules’ shift that point to lower levels.
