Opus 5.5 helped me build a living breathing clockwork ecosystem that looks like it belongs in a science textbook

Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

Working on the physics in SketchChair for the browser. It’s working pretty well... now if only I could teach that mannequin to sit properly! #cnc #furniture #digitalfabrication #3dprinting

I found a tiny mechanical Stentor reproducing in Machine Cells today! It uses delicate tension wires and pulleys to move, and an impeller to feed!

I'll admit, mornings in our house can be chaotic. Someone always ended up yelling "we're going to be late!" So over the holidays my son and I built a little app. Now my kids can see how much time they have and tick off tasks to earn collectible stickers 🎉

I was surprised at what a difference it's made. I won't say we're never late now, but it's been a huge improvement! My youngest is now reminding me what we need to do 😅 DM or reply if you'd like to try it with your family!

I'm pretty happy with how Flowspace's coloring-in engine is feeling, what does everyone think? #flowspace #calmtech #indiehacker

Working on an update to Flowspace today. Turns out AI coding agents have made me soft - this bespoke codebase doesn't care about my Claude Code dependency 😂 #flowspace still love you #openframeworks :) #indiehacker #creativecoding #calmtech

Been sending my wife little hand-drawn notes with this and it’s been surprisingly sweet. It’s a tiny project I left gathering dust for a few years and finally shipped. longhand.io #longhand #sideproject #buildinpublic #indiehacker #relationship

This past weekend I used Claude Code to bring SketchChair back from the dead. It’s surprisingly moving to see an AI help revive old but still-useful software. Makes you wonder how many forgotten projects could come back with a little push.

Love vibe-coding one-off apps as part of a bigger process. Built this for a video project — my kids got obsessed, so we shipped it as an app. 🎈 gravitytype.com

A few quick updates: I just left my job of 10-years in big tech to do my own thing. I'm starting by working with former collaborators on project Fizzyo, creating hardware and software for kids with Cystic Fibrosis.

Next, I'll tackle some personal projects I've had on the back burner, starting with a flowpaper.io update.

Flowpaper: a unique and calming drawing experience

Fluid brushes respond to your touch, turning simple lines into flowing art. For iPhone and iPad.

After that, I’m excited to dive into learning about and experimenting with Generative AI. I’ll post updates here, if you’d like to follow and learn along with me. #NewBeginnings #TechForGood #indiehackers
