Amusing historical note, that's where the word "breadboard" came from. Wooden cutting boards were readily available, and people would make circuits by screwing down tube sockets and other components.

Engineers are accredited in the US too. But there is an "industrial exemption" that allows you to work as an engineer without a license for certain kinds of employers. You just can't offer engineering services to the public w

I've tried longer cables on the slower USB's. My experience is that it can be touch and go depending on the peripheral. As I understand it, cable length is limited by the round-trip time between the host and the peripheral. Where

Granted I live in a smaller town, but I see a lot of bikes on the bus. Given that we don't have a super dense transit system, bike + bus is a practical way for a lot of people to make buses work. The bike solves the "last mile pro

I admit that I'm just blown away by the metalwork in tiny little electrical connectors. To me it's as amazing as watchmaking, if not more so, because the connectors are multiple-nines reliable, dirt cheap, and probably have neve

For me it's vision and physical ergonomics. The GUI and mouse did great things for computing, but were never strictly safe from an ergonomic standpoint, and I see a lot of people walking around with carpal tunnel braces. Especially CAD

I'll definitely steal the phrase (with attribution of course). When I first started using Jupyter, I was curious about the idea of turning a notebook into a paper or book by hiding all of the code cells. In fact I learned how to do it,

Ooh I'll take a look! Sometimes I get behind the times because I have to find a favorable dev board.

Going further, if you're a hobbyist, you're probably instinctively prioritizing the aspects of the hobby that you enjoy. My first app was a shareware offering in the 1980s, written in Turbo Pascal, that was easy to package and onl

I think the problem is similar to insider sports betting, which is that once someone has made a bet, they will try to influence policy decisions in order to profit from that bet. It's not so much insider knowledge that's a problem

My mom was teaching CS in the early 80s, and subscribed to Byte. The ads were of little use for me, as I had zero money, but of course I flipped through them anyway. I devoured Ciarcia's Circuit Cellar and I think it was one of the m

I think you have this backwards. Condensers and electrets (a form of condenser with a permanent charge on one terminal) almost always have a built-in preamp. The reason is that they cannot drive a capacitive load of any magnitude, and their

I worked with a brown laser when I was in grad school. It made a couple of brown spots on the wall by accident.

This will be interesting to try. I'm not an engineer. I decided to try "vibe coding" a CAD model, by letting AI generate Python code within VS Code. I was able to make a primitive but useful part, and sent it off to Xometry.

For that matter, how does a business differentiate themselves, if people can write their own software? While we're busy trying to replace our employees with AI, our customers are trying to replace our products with AI.

What are the statistics on this? There are about 500k professors in the US, and they make up about 1/3 of college teachers. Also, most academics would object to this situation, so it's not apparently OK. There's a growing mov

Not an issue for the author but a rolling desk chair on one of those plastic mats made to protect a carpeted floor are the perfect storm for generating static. Also a fun fact that gas tanker trucks used to drag a chain for this reason.

I'm not blaming you here, but I think "automatons" may be inaccurate. A lot of the jobs that seem menial would be utterly bollixed if done by an automaton. The people continually handle the edge cases and tiny discrepancies b
