From Thought to Circuit in Record Time with AI

Thus far, if the truth be told, I’ve had mixed experiences with large language models (LLMs) and generative artificial intelligence (GenAI) as personified by ChatGPT. I started, as many people do, by asking ChatGPT questions about things I knew nothing about, receiving responses that appeared to be reasonably impressive.

The reason for my emphasizing the word “appeared” in the previous … Read More → "From Thought to Circuit in Record Time with AI"

NIST Issues New Quantum Crypto Standards for Cyberspace

NIST, the US National Institute of Standards and Technology, has finally published a trio of new standards for post-quantum cryptography (PQC) in an attempt to get ahead of the coming cryptography crisis that’s forecast for the time when quantum computers get powerful enough to crack current RSA (Rivest-Shamir-Adleman) public-key encryption standards.  Although the RSA algorithm was published in 1977 and predates the Internet by a decade or … Read More → "NIST Issues New Quantum Crypto Standards for Cyberspace"

Unobtainium is where you find it: What happens when you can’t source an old IC?

If you’ve designed electronic systems for a while, or if you’ve repaired vintage electronic equipment, no doubt you’ve run into the fascinating term “unobtainium.” Here’s Wikipedia’s definition of the term:

“Unobtainium originally referred to materials that do not exist at all, but can also be used to describe real materials that are unavailable due to extreme rarity or … Read More → "Unobtainium is where you find it: What happens when you can’t source an old IC?"

Desktop Satellite Tracker antenna rotates in orientation, but does not change XYZ position. Accelerometer measures angle between antenna axis and direction of gravitational acceleration. Magnetometer measures angle between antenna axis and direction of Earth's magnetic field. From these two measured angles, direction of antenna axis is calculated.

@Karl Stevens, I agree with you that soft-core processors on FPGAs make little sense from a speed/power/cost perspective, yet if using one can meet your performance needs and avoids adding another chip to a design, it's likely worth it. Adiuvo's Leonidas FPGA tile is a tabula rasa. Put ...

Desktop Satellite Tracker video is EXCELLENT!!! Antennas are one part of radio that hasn't been obsoleted by A/D and D/A converters. My congrats to Zeke and the others!

Well I am back and the silence is deafening. Soft core processors are simply too slow, no matter what ISA PERIOD!!! The block diagram implies FPGA as "glue logic"...been there, done that. Using if/else to evaluate Boolean expressions is too slow no matter if a soft or embedded ...

Nice story. Wow! Evergreen Aviation. I haven’t heard that name in a while! (https://en.wikipedia.org/wiki/Evergreen_International_Aviation) I assume you’re familiar with their background and what an interesting guy their founder Del Smith was? When Air America closed down it was Evergreen that bought ...

You wax eloquent as always my friend, on what, “...tis a consummation devoutly to be wish’d…”. I shall therefore send a “slightly evil” minion (Operations and Maintenance),to you to ring out further details (all the really evil minions (Design), are required by law to remain in California - ...

"Wow! Could these be used with the “Hofstadter-Moebius Loop” logic system that operates my fully-automated, Trebuchet (that fires GPS-drone aimed, canard-guided projectiles made of FRP inside red Georgia clay, and shaped to look like a full-sized, 1955 Buick Roadmaster)?" Well, Duh!
