An entire book about electronic connectors. You read that right. And I spoke with Davide Andrea about how he wrote it and all the tools he put online to support the book that are free. Fascinating discussion, check it out.

200 Gbps analog IP blocks on leading edge 2 nm nodes from TSMC and Globalfoundries. No, I haven't magically gained superpowers, I instead talked with Joren Vaes about his work at SOFICS on The Amp Hour this week.

I've been 3D printing up a storm on to hook things onto DIN rail and talked about that and many other things on The Amp Hour this week

What happens when one of the main providers that enables #opensource #silicon to thrive...shuts down? Companies like @mith.ro's new wafer.space jump in and offer an even more compelling option. $7K for 1000 chips on the GlobalFoundries GF180MCU process. Learn more:

More open source hardware! This one is a smaller add-on board, but in service of making lots of #bluetooth nodes that connect using Golioth's Bluetooth-to-Cloud service.

With #tariffs in the US and different PCB assembly options, it can be tough to optimize for cost on a project. I talked about my experience using JLC assembly + #KiCad on episode 700 of The Amp Hour. Other topics included #solar, #batteries, #bluetooth.

12 years ago, I talked to Andrew Seddon who was building a datasheet/footprint tool for #PCBdesigners. CircuitHub has since transformed into a digital factory for on-demand PCB assembly. We discussed #tariffs, #domesticmanufacturing, AI changes that to the industry

I love watching Matt Brown's videos reverse engineering #iot products that have ...let's say "less than stellar" security implemented. He shows his hardwaer #reverseengineering and we get to follow along and learn with him.

I talked to Matt on ep698 of The Amp Hour

Tim from Mitxela kind of does it all: (super tiny) electrical, (super tightly written) firmware, (super nicely finished) mechanical. We dug into what motivates him to keep making and how he hyper optimized things like the fluid (LED) pendant.

I have always wanted something like an #ssh connection to the #iot devices I work on. Today we published about how to use #Golioth RPCs and a simple front end to do just that.

I'm working on a video where Rajeev from Conexio optimized a #zephyrrtos program and hardware configuration to send every hour without needing batteries. Uses a Nordic nRF9151, solar panel, and supercap

I talked about my upcoming solar install on TAH this week. Also wacky tariffs, peak power pricing, tiny electronics (AirTag clone course), oscilloscope triggering, and more.

Hardware decisions are expensive over the long term. What if you could simulate a huge range of chips at the beginning of your design to determine which one to use?

Michael Gielda of Antmicro and I spoke on about understanding your problem space in intricate detail

I've been challenging myself to make some really tiny PCBs using Bluetooth chips (nRF52840). I talked about it on TAH this week (among other things), and hope to share the boards soon.

What happens when you take a switch matrix and allow any net (strip) on a breadboard connect to any other net? Well, really interesting things, it turns out.

I talked to @architeuthisflux.bsky.social about the Jumperless breadboard and how it all works

I chatted with the embedded team at @raspberrypi.com about the #RP2350 on The Amp Hour. It's an amazing "dual dual-core" part that is finding its way into many products. We chatted #hardwaresecurity and #lowpower, as those were key enhancements over the #RP2040.

2025 is the year of the Pick and Place Desktop! :-D

Well...maybe for me?

I enjoyed recording with @hawes.dev about the @opulo.io Lumen and all of the experiments and successes as they have built up the company and open source machine I hope to have some day.

After stating for literal years, "oh I should install octoprint on a Pi", I just successfully printed from the console for the first time. It was, of course, super easy to do. Procrastination is a helluva drug.
