The Amp Hour Electronics Podcast

We are doing a 2025 listener survey! Answer the survey and put in your email to win one of three Jumperless OG units donated by Kevin Cappuccio (past guest of the show) Note: this was corrected from the original, these are not v5 units, they are the original Jumperless units. Apologies for the confusion ~CG Chris signed on to get solar installed He’ll be taking advantage of Duke Energy’s PowerPair, a program to get a bulk amount for the battery and ongoing payments to act as a virtual power plant. Telsa Powerwall 3 Teardown Australian politicians are proposing money for batteries for everyone in Australia Peter Walkinson batteries CATL batteries Back powering off a Chevy Bolt AC battery power Peaker plant Check out the rates for peak power in New South Wales (high!) Base load Chris is working on a new series for tiny hardware nRF52840 With careful planning, it’s possible to get a “0.4 mm pitch” (found out it’s actually 0.35 mm!) onto the JLC 6 layer process because they now allow via in pad. Jumperless v5 episode (though as a reminder, we’re giving away the OG versions, not the v5) Dave review of Jumperless (mailbag video) We are doing a 2025 listener survey and added some new questions Slow trigger  R&S version  Laminated cheat sheet Jeff Geerling Bosch video  The Tariffs in the US are an absolute mess. Since recording they have been downgraded, but they are definitely still going to have some outsized influece on the electronics world. Chris thinks that it makes more sense to race to the bottom of available parts (like the new $0.10 CH572 with Bluetooth), pay the tariff, and put in more time and effort on the software. Not that Chris is the intended audience, but also that it’s not going to have the effect that is Ghostbusters song
