The Amp Hour Electronics Podcast

Dave and Chris are back after a long vacation absence to talk about high end events, new scopes, fast board assembly, and nerds nostalgic for the sci fi future that never was.

Dr Barry Marshall won the 2005 Nobel Prize in Physiology or Medicine for discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease. But Barry is also an electronics hobbyist and vintage HP and Tek oscilloscope and vintage computer enthusiast. He visited the EEVBlog lab and sat down with Dave for an impromptu discussion about all sorts of things. https://www.nobelprize.org/prizes/medicine/2005/marshall/facts/

Davide Andrea is the author of The Electronic Connector Book and Principal of Elithion, a company that designs Battery Management System. He joins Chris to talk about the wide and wonderful world of connectors.

This week Dave and Chris discuss test equipment, the Arduino acquisition, Zephyr, Altium pricing, private equity owning YouTube channels, audio circuits, and more!

Joren Vaes is a design engineer at SOFICS working on simulating and delivering analog IP blocks on leading edge nodes like the 2 nm node from TSMC. Listen to how they bend physics to their will to make the chips that power our modern electronics.

This week Dave and Chris discuss DIN rail, IAC (featuring Space Lube), begging for Moonlanders, batteries, 10x-priced connectors, Gridfinity, concrete slabs, and more.

Jerry Twomey, author of Applied Embedded Electronics, joins Chris to talk about how to build more reliable hardware when there are embedded components involved. And these days, there are almost always embedded components involved.

Tim 'Mithro' Ansell returns to The Amp Hour to discuss his new Singapore based wafer sharing service called wafer.space. Now that eFabless is no more, this venture will aim to make silicon even more accessible to the masses, driving down the costs on a per chip basis. For $7K, you get 1000 chips delivered on a 180 nm process from Global Foundries.

Dave and Chris discuss solar, nuclear, making new injection molds from old ones (or not), and how to probe poorly placed test points with tiny needles.

Todd Bailey has been busy in the 11 years since he was last on the show. He has designed submarine sonar and many different pieces of space electronics, the latest being a hall effect thruster that uses solid propellant for his now sold company Starlight Engines.

Dave and Chris record after a long break between episodes together and discuss new electronics designs they're working on, solar and battery installations, dealing with tariffs, and building at JLC.

Andrew Seddon, founder and CEO of CircuitHub, joins Chris to talk about how CircuitHub has changed over the past 12 years as a startup and how they are continuing to push the boundaries of high mix domestic electronics manufacturing.

Matt Brown is a hardware and IoT security researcher. He joins Chris to talk about best practices for securing hardware that talks to the internet and share stories of products that didn't pass muster.

This week Dave and Chris discuss solar optimization, short videos, useless products, cameras, energy monitors, Bluetooth, magnets, and more!

Sam Aldhaher is a power engineer and 3D graphic artist, his Blender visualizations have helped many people understand how RF flows in a variety of circuits. Sam joins Chris to talk about how to get started in Blender and the variety of tools available once you do.

In this episode, Dave and Chris cover environmental monitoring, trade shows, manufacturing, tariffs, new test equipment, and AI coding.

Colin O'Flynn returns to The Amp Hour for a 3rd time to talk about recent developments in security, FPGAs, small scale electronics manufacturing, and the world of academia.

In this episode Dave and Chris discuss solar installs, wacky tariffs, peak power pricing, tiny electronics, oscilloscope triggering, and more.

Michael Gielda returns to the show (for a third time) to talk about the work AntMicro is doing to extend hardware, firmware, and silicon design. Their new tool System Designer allows even more high level testing of full systems, in addition to their popular Renode tool.
