48 components soldered by hand, 6 by @JLCPCB. My AI-assisted Nissan Leaf heater controller, is taking shape! Learning to solder has been fun, with plenty of help from my friend Adi. Next: test it with a current-limited bench supply before connecting it to the car.

Vibe-coded websites are getting old fast. I’m sharing this one anyway! Sometimes I need to know how dark it will be somewhere at a specific time. I’ve tried to get every new generation of LLMs to build me a website for this, and they’ve all failed. Until Opus 5.5. Its version looks good and actually works. Pick a place, date and time, and it shows you whether you could read a sign in that light. howdarkisit.com/

So much fun hosting @bot meetup in Oslo last week! Thanks to everyone who came, and a special shoutout to the Swede who drove three hours each way to attend. Big thanks to @naoufal_elh for joining us remotely. Photos by the awesome Ivana Piljic.

Trained a Norwegian speech-to-text model on EmbeddingGemma 2's audio encoder. 10–40× faster than NB-Whisper, ~$15 to train on one H100. Not as accurate yet (10% vs 4% WER on FLEURS). Idea from @TslShahir, recipe from @stablequan's QUAN-Transcribe. github.com/ahdrage/norsk-asr

The Leafy boards have arrived! I used AI and KiCad to design a Wi-Fi controller for my Nissan Leaf’s heater. JLCPCB soldered the trickiest parts. I’ll do the rest. Next: practise on a spare board, finish assembly and find out if it actually works.

Grok 4.7 is here. It's a notable improvement over Grok 4.6 at the same price and speed.

I’ve had enough of cold winter mornings in my Nissan Leaf. So I used Astra to design a custom PCB with KiCad that will let me turn the heater on and off from my phone. I sent the design to JLCPCB to manufacture the board and solder the trickiest components.

I’ll solder the easy stuff myself. The remaining parts are ordered from Mouser. The board is being manufactured now. Pretty insane that I can get a custom, one-off board made for $80.

Compile in London is on! Amazing talks, venue, atmosphere and food! Kicked off by @benln and @davidgomes followed up with a talk about the journey from worktrees to cloud agents.

For those who outgrew Supabase: at what stage did you move off it, and where did you move?

We've partnered with SpaceXAI to train Grok 4.5. It’s our most powerful model yet and the first we've built for more than software engineering.

Introducing Cursor for iOS. Build from anywhere by launching always-on cloud agents. Or remotely control agents running on your computer from the app. Composer 2.5 is 75% off in the app now through July 5.
