I've been so worried about the Great Pacific Garbage Patch. It's a monument to environ...
Hi All!
It's 84 degrees her in Chicago and everybody is eating lunch outside. I hope nice weather is happening wherever you live. Now, back to work!
I'm writing today because I'd like to get 2 judges for our Experimenting with Current Sen...

Should they really crackdown on cheating?
Lockdowns have forced schools to adapt to remote learning, a more challenging experience compared to i...
Current sources and sinks have applications in many circuits and there are many ways to make them. This blog is a brief introduction to single transistor current sources. Horowitz and Hill cover this material in a more det...
If you are like me you don't use the XY plot function on your oscilloscope often but it can be handy at times. I was reviewing videos by W2AEW on YouTube and saw this one where he describes a simple method for viewing c...
Summer is around the corner. I'm hoping for a summer of sunny days and warm weather. What are you planning for this summer? For myself, I'm attending the Sensors Converge Conference in San Jose, CA, June 27-29, 2022. The conference will feature a lot...
It’s been difficult to miss news sites, and social media feeds: the planet is in trouble, and we are in need of solutions for our warming world. The latest climate report from the UN’s independent scientific body, the Intergovernmental Pa...
It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of...

Is it summer yet?
I'm a warm-weather person, so summer is my favorite time of year. But it seems like the Spring this year in Chicago has been cold and wet, and moving forward too slowly for my taste.
To get everyone excited about the Summer (inc...
Another attempt at measuring the open-loop dc gain of an op amp, this time using the 'false summing-junction' method. The idea for this one came from a TI document comparing different approaches to testing op amps[1].
Before doing it for real, with a...
My friend Adrian recently showed me a plugin for KiCad that makes determining placement of components while populating a PCB easier. KiCad 6 has a feature that makes adding plugins simple. Open up KiCad and select the Plugin and...

Researchers at Keio University in Fujisawa, Japan, discovered a direct link between folk music ...
As I still had the prototype board set up from looking at the open-loop gain, I thought I'd try another quick experiment. This time I'm going to attempt to measure the output resistance. I'll do this by back-driving the output of the DUT [device unde...

Engineering remains a male-dominated industry, with women making up just 15% of working professional engineers as of 2019, but that is not the whole story of the industry. Despite men disproportionately filling roles, women have made great strides in...
I just received my Secret Santa present (not quite what was intended) - thanks to redcharly , dychen , and E14.
The intended gift was an Arduino Nano 33 BLE, but those were on backorder and the availability date kept slipping - so Dave let me pick so...
Even though access to science and engineering education in the US was incredibly limited until recent history—the first Black graduate of MIT, Robert R. Taylor, graduated in 1892—Black Americans have a significant legacy in the scientific...
