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 Cappuccio 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.
