It was Australia Day when Dave and Chris recorded The pinnacle of stereaming services: The Amp Hour+ Chris just got a new solar quote for his house, the roof shape is still too weird to make it a good option. Thunderbirds episode Solar city panels starting on fire Dave is looking at upgrading his solar again, including with DC batteries Span.io is working on smart circuit breaker boxes The Grid book Sydney program to use homeowners’ batteries How many times has this guy gotten laid off? (the one scamming for 8-10 engineering jobs at a time) Big layoffs are hitting the likes of Google, M ..read more

“Time is a (flat) circle“ Dave has been making videos about jellybean components, the latest about references and regulators PCB requirements Pricing pressures There was a fire in the Eurocircuits Hungarian factory. Chris was told about the DFM tool from past guest Joris Digikey was mentioned in a recent episode of Planet Money talking about the runway in Thief River Falls Wendover Productions talks about How Ocean Shipping Works Digikey location on a map Chris recently took a train to Washington DC Dave warned Chris about doing electronics on public transport, as someone was recently a ..read more

This week our sponsor is Keysight Technologies, who are ramping up a new contest called “Stump The Experts” and is focused on Keysight’s 5G testing technologies. You can learn more and enter the contest by going to TheAmpHour.com/5G Dave tore down his ATEM mini ISO Internally there is a Xilinx Zynq that has an $1800 single piece price The pipelined data path can also do things like Chromakey Texas power outage Lawrence Krause Dave is upgrading his solar Can solar be used as a hedge on inflation? North vs south facing depends on your latitude. String inverter vs microinveter John Edmond of Cr ..read more

Welcome, Natasha Baker, Founder and CEO of SnapEDA! Natasha has an EE background, she got her start working on tools at National Instruments She was reading IPC-7351 specs early on. What’s in there? All about how to create footprints, with different density levels, depending on the complexity of your board Most Nominal Neast A new version is coming out soon, check IPC.org for more info With corporate sponsorship, anyone can participate (and Natasha recommends it!) Interesting discussion around using an X shaped pad under a QFP Later, Natasha got interested in the marketing side ..read more

Dave did a teardown of a plane transponder, so we talk a bit about RF (without much knowledge) There is a PIC16C84 on board Learning or relearning Transmits 1030 MHz, receives 1090 MHz, 140W We’ll ask Jeff Keyzer on the upcoming Keyzermas Crystal radio is basically a pin diode with long antenna. Dodgy wiring on 3.5kW aircon Coefficient of performance Dishy (Starlink) teardown. Discussed briefly when Joris Aerts (518) was on the show. Which PCB software is the best? Question posed by past guest Robert Ferenec. 100 Photos vs 1 Photo anecdote Greg Davill is doing an “Advent for circuit boa ..read more

Welcome Brandon Gilles and Brian Weinstein of Luxonis Holding Corporation They make the DepthAI system, which uses the Intel Movidius Myriad X It was initially created for life safety problems, specifically targeted at distracted drivers. There is research that a car horn on a bike can help to lower fatal interactions. Brandon had multiple people in his life hurt or killed by cars while biking. Though a systemic change is needed, a tech solution is more likely in the short term. They built a hardware protoype and spent a couple hours of coding to prove out the concept. “Depth perception + CV ..read more

Dave had a recent video about selecting different op amps for the microcurrent (maintaining engineering!) ADI buying Maxim Maxim sampling policy Will there be a large amount of crossover parts? Microchip sent out a letter asking for better visibility into the backlog Boards with stackup Video about reviewing PCBs of forum member Chris borrowed an idea from past guest Luke Valenty about how to use pill shaped pads on the tinyfpga bx. This enables using a larger Process for PCBs “Lowest common denominator design” is the idea of choosing a PCB fab that has a very small space/trace, but only nee ..read more

Dave has been playing with a “Mint in box” Vintage Intel dev board Huffing my way to freedom Bake in the stackup on the gerbers, and they’ll always see it in the cam program Chris recalls Ted Yapo doing a test coupon for his sampling oscilloscope project. Dave talks about using the extra space on a panel to make test coupons in his panelization video. It was an “Instant sackable offense” at Dave’s past company for not ESD testing before coming into the lab, because they were working on boards that cost 6 figures. Chris has been thinking about team size (mostly because he’s normally a te ..read more
