When I decided to purchase a “for parts” copy of a Heathkit SM-2420 frequency counter from an eBay seller for $60 back in 2023, I had no idea what I was getting into. The unit was listed as not operable. Its line cord had been cut off, leaving a short and very sad looking pigtail. Nevertheless, it was a Heathkit frequency counter. I’d wanted one for decades. … Read More → "Saving Two Old Heathkit Frequency Counters"
Let’s go to space!!!! This week, we’re diving into the cutting edge of AI in space with Pratish Shah of Aitech. Pratish and I discuss Aitech’s IQSat – the world’s first AI-enabled picosatellite constellation platform, and how the shift to AI in space computing is changing the economics and timeline for collecting and analyzing data beyond Earth. We’ll also cover the immense … Read More → "From IQSat to Artemis II: Aitech’s Vision for Intelligent Spacecraft"
The following glossary provides a quick-reference guide to many of the terms, acronyms, concepts, and technologies that we discussed in my previous column. Some of these definitions are necessarily simplified (entire books have been written about many of these topics), but they should at least … Read More → "A Little AI Glossary for Your Edification and Delight"
Things are changing incredibly quickly in the AI space. Only a few short years ago, most people barely knew AI existed. Today, by comparison, they use it every day, often without realizing it, and the pace of change shows no sign of slowing.
The problem is that AI isn’t one thing. It’s a sprawling collection of concepts, techniques, … Read More → "Everything You Wanted to Know About AI (But Were Too Afraid to Ask)"
Back in early 2024, I discussed SiTime’s MEMS-based temperature-controlled and oven-controlled crystal oscillators (TCXOs and OCXOs) as replacements for ubiquitous crystal oscillators. (See “Adventures with SiTime’s MEMS-based Super-TCXOs – Super Accurate Clocks for the Future – Part 1.”) In that article, I wrote:
My podcast guest is Andy Hock, Chief Strategy Officer at Cerebras. Andy and I discuss the the revolutionary details of the Cerebras Wafer-Scale Engine (WSE). We also explore where the next major competitive frontier lies for AI hardware, how the latest WSE addresses the critical latency and energy efficiency challenges of deploying massive AI models for inference and … Read More → "Democratizing Large-Scale AI: The Future of AI Hardware with Andy Hock from Cerebras"
