Description
Chris Gammell and Dave Jones' voices span the chasm of thousands of miles each and every week to speak to each other and industry experts about where the field of electronics is moving. Whether it be a late breaking story about a large semiconductor manufacturer, a new piece of must-have test equipment or just talking through recent issues with their circuit designs, Chris and Dave try to make electronics more accessible for the listeners. Most importantly, they try and make the field of electronics more fun. Guests range from advanced hobbyists working on exciting new projects up through C-level executives at a variety of relevant and innovative companies. Tune in to learn more about electronics and then join the conversation! Visit The Amp Hour website for our back catalog of 150+ episodes.

This week Dave and Chris talk about upcoming demos, bluetooth, car troubles, new silicon, parts in the lab, and more!
Carl Bugeja joins Chris to talk about building PCB motors and actuators, starting a new business, documenting build processes on YouTube, manufacturing flexible circuits, and much more!
Dave and Chris discuss EVs, adapting power tool batteries for projects on the bench, robots, software updates, and more!
Pallav Aggarwal of CAPUF Embedded joins Chris to talk about blogging about learning electronics and helping others learn along the way! Pallav does teardowns, chip walkthroughs (like on the CH32V003), Linux projects, custom hardware, and more!
Chris and Dave discuss SPICE in CAD programs, new software releases, startup paperwork, crazy smarthome stuff, and toothbrushes that give away your data.
Dave and Chris talk through Renesas acquiring Altium and all its implications. Also Dave gives a history of Altium and they discuss how the industry might change (or not).
This week Chris and Dave discuss relativistic time differences, building with RISC V components, RF modules, silly consumer hardware, underwater electronics, and more!
Keith Burzinski of Nabu Casa works on ESPhome and making it easier to attach custom hardware to the open source home assistant project. He joins Chris to talk about the realities of offline smart home setups and how you can get started building custom things.
Dave returns after a few weeks on holiday to chat with Chris about robots, maker companies merging, hyped up tech at CES (and beyond), trains, power grids...and more!
Jeff Keyzer of Mightyohm.com joins Chris for a later-than-usual holiday episode, recording on what will be known as The Twelfth Day of Keyzermas
Dave and Chris discuss moon landings, oscilloscopes, design decisions for limited peripherals on microcontrollers, coding, smart home programs, and more!
Benjamin Cabé, developer advocate for the Zephyr Project, joins Chris to talk about the popular Ecosystem and Real Time Operating System (RTOS). Listen if you'd like to get started with an exciting firmware product that can really enhance your next project.
Chris and Dave return after a few guests shows and missed weeks when Chris was out with a new baby in the household. This week we talked about China, chip supply, RISC V, PCB tradeshows, LED factories, and more!
1Jeff Geerling of the Jeff Geerling YouTube channel joins Chris to talk about how to explore the wide variety of computing devices, from an ESP32 monitor on your garage, all the way up to a multi-rack server.
Andreas Olofsson is the CEO of ZeroASIC, a company that will build you a custom ASIC using chiplets. He returns to The Amp Hour to talk about what has changed in the chip(let) industry in the last 8 years and how they will lower the cost for quasi custom designs for the masses.
Kathy Joseph from Kathy Loves Physics joins Dave on The Amp Hour to discuss history and physics and we end up discussing the intricate history of the development of the Cathode Ray Tube.
James Adams and Liam Fraser of the Raspberry Pi hardware team once again join Chris to talk about the RP1 custom silicon on the Raspberry Pi 5
Dave hangs out with Fran Blanche for her 4th appearance on the show. Space, Youtubing, tube testing, storage nightmares, and oopsies.
Chris and Dave discuss selling low volume hardware, old stock of chips, Intel's weird investments, creating oddball PCBs, scopes without fans, and more!
Scott Williams returns to The Amp Hour after 6 months to discuss the technical aspects of consulting, including some of the tools he reaches for when building a new product

Superconductors 100.5 (I'm not wise enough to do a 101): Superconductors have a critical current (or magnetic field) above which they lose their superconducting property. The max current tends to increase as the temperature drops. Opinion: SCs, even if we get them working above room temperature, will never be cheap enough for widespread use just to power chips, or cars, ot homes.
Framework laptop would suit me, because I'm a cheapskate and I want to reduce wastage. I think the modules connect via internal USB Type-C, so the Type-C module is just a port saver. Imagine giving a live coding conference talk and finding they can only take Apple iThing connections. Easy. Open your "Joe 90" briefcase, grab the iThing connector module and stick it in where the other video output module was. A bit neater than carrying adaptor cables. And laptops are getting harder to repair/upgrade, while Framework reverses that. My current portable is still a old and beaten-up Lenovo laptop (Flex 14" 20404). Fitted maximum RAM and a big SSD. I only write code and assemble/compile and it's fast enough, so I'll look again at Framework when old faithful can't cope any more. My old Lenovo is easily repairable for battery, screen, keyboard, RAM, fan, connectors. I'm not so sure about newer stuff, so if I buy a Framework, maybe it's a vote, as well as making repair easy?
There was a chip released that I called an "Erg Thief". I got the release though the post (don't know why--I'm a semi-retired programmer who drives buses!). Anyway, it reckoned to run from about 0.4V, needing (from memory) 1.2V to start. The sheet listed charging from a single solar cell as an example. So, for moon power you need a lower PV cell voltage to reduce the leakage. 0.2 or maybe even lower? This chip could power your quartz clock from the Moon. Gotta be worth it :-)
Interesting conversation about LoRaWAN, DASH7 and IoT telecomm in general
awesome podcast...been tired of searching for electronics podcasts... ultimately reached here
