- 🙀 This Circuit Board Is a Watch My background is software and AP Physics. This year I designed a wristwatch that is just 1 circuit board, and PCBWay built it. Here's what I learned.
- 🧠 Work We Couldn't Afford At Zoom, engineering hours decided which platforms got parity. With AI, a solo developer can close gaps that used to mean falling back.
- 🙃 I Kicked Alexa Off My Echo Spot and Installed Doom How I unlocked a first-gen Echo Spot, installed LineageOS, and turned it into a custom clock, a local voice assistant, and a tiny round Doom machine.
- 🎨 I Turned a Tiny Wi-Fi Cube Into a Stats Display for My Mac Studios How I flashed a GeekMagic SmallTV-Ultra over Wi-Fi to show live CPU, GPU, memory, temps, watts, and fan speed from a Mac—no soldering, no root.
- ⚡ When the Compiler Is a PCB Factory I thought sending a board to a factory was like printing a PDF. Then the factory's output changed one LED—and asked me to approve the result.
- 👻 The Business Card That Lights Up When You Tap It I made a circuit-board business card that opens my website and lights an LED with power harvested from the phone tapping it.
- 🏮 The Chord Your Keyboard Can't Play I built a tiny piano app and found a chord that physically cannot be played on a MacBook keyboard. The bug wasn't in my code—it's soldered into the keyboard, and it's been there for sixty years.
- 🕺 I Ran DeepSeek V4 Flash Across Two DGX Sparks Over Ethernet NVIDIA recommends a 200G fabric for clustering DGX Sparks. I made tensor-parallel DeepSeek work over an ordinary 10GbE cable—and measured what the slower link costs.
