first race of 2026 tomorrow!

compliant mechanisms are incredible.

fridays are for demos!

The Amp Hour is always good, but this episode with @chrisgammell.bsky.social and @ericmigi.com is truly excellent. They do a great job of articulating the challenges, trade-offs, and, ultimately, the joy of building consumer hardware products that you can call "done". Give it a listen!

good morning, orange site.

tonight I watched a norwegian man run up a hill at sub 6 min/mi pace... on skis. the olympics are incredible.

looks like we are doing the orange site this morning.

using solder to strip enamel from 28 AWG copper wire.

It's always kind of interesting to see people in very public influential leadership positions have extremely emotional reactions to competition and objectively minor critiques. Outside of it being textbook poor leadership, it also makes you wonder how they even make it through an average day.

happy nyc marathon registration day!

**Making Ferrite Core Inductors at Home** New post in which I walk through how to make inductors, and how the construction of an inductor impacts its attributes, particularly in the case of using a core material with high magnetic permeability. danielmangum.com/posts/making...

my grandmother somewhat regularly pops up on LinkedIn and drops a comment on one of my blog posts to the effect of “I understood none of this, but I love you very much”, and I for one think that’s pretty freaking awesome.

TL;DR: Empathy for what customers are going through with their own builds Building hardware gets you into the nitty gritty details of building IoT products, including some of the challenges our customers run into with our services. blog.golioth.io/why-build-ha...

all fast runners I know are great at running fast. all very fast runners I know are great at running slow.

I am not surprised that this is troubling, but I am troubled that this is surprising.

1. mistakes were made on this joint 2. iPhone cameras are incredible these days

the xkcd “waiting for my code to compile” looks more like this at @golioth.io on a Friday evening.

the continuity checks will continue until morale improves.

I think this is the first time we have had a full time student on The Amp Hour? But my goodness, what a student and what a guest! Aaed has been building robots on his YouTube and sharing what he does with others, lowering the cost and barrier to entry into #robotics theamphour.com/712-robots-e...

therapeutic.

PCBite remains undefeated.

**3,500 Miles in 2025** I wrote a recap of my year of running in 2025, particularly focusing on a rather eventful final two months. One of the greatest joys in life is exploring our limits, and running is one of the most visceral ways to do so. On to 2026! danielmangum.com/posts/3500-m...
