RE: Electronics Engineer Builds a PLFM Open-Source Radar System

I remember my group testing some of the early models of these back in the 1990's.

I hope things have improved since then.

RE: ETH Zurich Engineers Develop Small Magnets That Achieve 38 and 42 Tesla

This is a reasonable extrapolation of utilizing high temperature superconductors for increased magnetic density.

I can see other uses for this technology beyond just NMR.

RE: Researchers Develop Water-Based Enzyme Inks, Simplifying the EBFC Manufacturing Process

I like it.

It would make gathering critical health information easier and reduce the impact for day to day use.

RE: SWOT Spots Large Waves During Major Storms

DAB — Thu, 12 Mar 2026 19:10:10 GMT

I have watched this technology evolve over the decades as people realized that rogue waves were real and deadly.

They still need some way for a ship to see a wave with time enough to steer into it so they can minimize the damage such a wave can do.

Worlds most efficient rick roll!

Almost like the movie Blade Runner, where id #s were inscribed in fish scales and hair follicles. Now their entire replicant ID and DNA structure can be stamped into their bones and vital organs, and read later under a microscope.

RE: NASA Made Its Sea Level Changes Data Publicly Available

Your conclusion is wrong.

The CO2 rise is due to the melting ice. The global warming is a natural event based upon the planet coming out of the last ice age.

There is no verifiable data that supports human CO2 generation as causing the current levels of global warming.

The rise in sea levels is only temporary.

As the atmosphere warms it will absorb most of the added water and raise humidity levels worldwide.

You will also get a more consistent rain fall rate worldwide, which will increase the amount of arable land.

RE: Researchers Captured a Visualization of a Hydrogen Atom’s Electron Orbital

These results seem to validate my atomic model where there is a shell of captured photons around a solid nucleus.

RE: LEGO Introduces New Smart Brick at CES 2026

An interesting direction, seems a bit more consumerist than their previous electronics which were more about getting people coding and experimenting

RE: Clouds of Microplastics Discovered in China

I shudder at the thought of what exposure over time will reveal. Augh crap, that wasn't a good idea was it!

The effects of micro plastics will be felt for centuries.

RE: How many gas sensors can be connected to an ESP32 microcontroller?

dougw — Wed, 21 Jan 2026 14:18:13 GMT

An ESP32 has up to 18 native A/D channels, but some pins would be needed for control, so you might get 8-14 analog sensors directly connected, depending on your control scheme. There are also lots of sensors with serial interfaces - not sure what type you are talking about.

RE: How many gas sensors can be connected to an ESP32 microcontroller?

michaelkellett — Wed, 21 Jan 2026 11:24:55 GMT

There is no simple limit - the ESP32 supports standard interfaces like I2C and SPI and UART.

There may be physical imitations but your cash will probably run out first.

Why not explain what kind of sensors you mean to use and how many you would like to connect, and why you want to use an ESP32.

Very interesting.

This innovation could be useful in greatly expanding the use of LEGOs.

RE: Connector Design for Harsh Environments: Miniaturization, IP Ratings, and Signal Integrity

DAB — Thu, 15 Jan 2026 20:17:18 GMT

Connectors are very important.

A USN study found that 50% of all avionics failures were due to connector issues.
