The Amp Hour Electronics Podcast

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.

Tim from Mitxela stops by the show to discuss his extensive portfolio of projects involving, hardware (tiny LEDs), firmware (ridiculously low power processing), software (emulating gameboy), and mechanical (machining jewelry grade objects)

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.

Dave and Chris discuss bluetooth boards, what happens when batteries leak, new cellular capabilities in iPhones, AC flicker, old oscilloscopes, and more!

Kevin Cappucio joins Chris to talk about the Jumperless Breadboard, an advanced platform for prototyping and interacting with circuits that you place onto the breadboard.

Dave and Chris discuss the Tandy 200, test equipment cashflow, the return of the Pebble watch, GPT trying its hand at CAD, solar output...and more

The RP2350 from Raspberry Pi is a dual dual-core (Cortex-M33 and Hazard 3 RISC V) microcontroller with extensive peripherals. Some of the Raspberry Pi team (James Adams, Chris Boross, Liam Fraser, Luke Wren) join Chris to discuss how the chip evolved from the RP2040, including interesting security and lower power enhancements.

Stephen Hawes started Opulo, a company that builds the Lumen Benchtop Pick and Place. Opulo designs open source hardware and sane software for building your own PCBs in your lab.

This week Chris and Dave discuss the changes at Intel, being in control data in your home lab, bogus copyright claims for repair videos, and more!

A full 3 hour discussion with the legendary Lee Felsenstein, designer of the Osborne 1, SOL computer, VDM-1, Pennywhistle modem, and the inventor of social media.

Chris and Dave discuss updated house wiring, making smart relays capable of switching power, how to design a linear supply, and using AI tools to help troubleshoot code (but NOT layout)
