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"

Microsoft BASIC vs DEC BASIC vs Dartmouth BASIC: Dartmouth BASIC was a compiler running on Dartmouth Time-Sharing System, a multi-processor mainframe disk-based system, so had features that diskless microprocessor BASIC interpreters lacked. 1960s shortwave radio-receiver radio-frequency circuits, bipolar transistors vs vacuum tubes: Transistors were lower power, but tubes had better ...

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!
