I first heard about this in an former coworker's (Robin Berjon) talk https://www.youtube.com/watch?v=s878bm15mrk at an IPFS conference

Fascinating

He writes about these things on this blog as well(https://berjon.com/ethicswishing/), and has a forthcoming book on related topics last I heard

New comment by meandave in "Show HN: Crew Chief – OBD2 diagnostics via cheap Bluetooth scanner"

meandave — Wed, 18 Mar 2026 17:05:08 +0000

I'm in talks with some factories that manufacture the scanners, I'd like to produce branded versions and ship them out automatically to users who signup for the paid plan, but I need to get some initial users first to verify the idea. Eager to move onto the next steps and build all of that out

Show HN: Crew Chief – OBD2 diagnostics via cheap Bluetooth scanner

meandave — Wed, 18 Mar 2026 17:02:49 +0000

I have too many vehicles. Cars, motorcycles, tractors -- they pile up when you can't say no to a project. Keeping track of everything across all of them was the problem: which parts I ordered for which thing, what codes I pulled last month, when I last changed the oil on the tractor.

It started because I got tired of typing my year/make/model into RockAuto and AutoZone every time I needed a part. So I built a browser extension that auto-fills vehicle info from a saved garage. That lasted about a week before I started bolting on more features.

The diagnostic pipeline is where I've spent the most time. The mobile app pulls OBD2 codes from those $15 Bluetooth ELM327 scanners, then sends them to an LLM with vehicle specs, known TSBs, and common failure patterns for that specific make/model/year. ranked probable causes, DIY vs shop cost estimates, severity rating, and linked a ChrisFix video for the repair. I've been tweaking the prompts and context window for months. The whole point is closing the loop: check engine light comes on, pull codes from your phone, get a report telling you what's wrong, how bad it is, and how to fix it.

Other stuff:

- 50 state selling wizard - generates the correct bill of sale, title transfer docs, and disclosure forms for any US state. - 16 vehicle types with type-specific fields (PTO type for tractors, hull material for boats, engine CC for motorcycles, etc.) - Task boards per vehicle - kanban for garage projects with parts-ordered/received/installed tracking.

TypeScript throughout. The extension, web app, and mobile app share a backend.

Free tier is 1 vehicle with full features, no credit card.

Been heads-down for a while and just now coming up for air.

Happy to answer questions about the OBD2 integration, the LLM diagnostic stuff, or the 50-state document generation.

Crew Chief (https://crewchief.cc) — a Vehicle diagnostic and management tool. Plug in your OBD2 codes (or just describe symptoms) and get a structured diagnosis in under 30 seconds: ranked probable causes, DIY vs. shop cost estimates, severity rating, and matched parts/repair videos.

I have too many project cars and bikes, I wanted one place to store vin numbers for searching parts, and then just kept adding useful features.

Supports 16 vehicle types (cars, trucks, motorcycles, boats, tractors, ATVs, RVs, etc.), not just cars. Also includes maintenance tracking, a browser extension that auto-fills your vehicle info on parts sites like RockAuto and AutoZone, a community-vouched trusted shops map, and a vehicle selling wizard with state-specific bill of sale generation.

Free tier gives you 1 vehicle with a full diagnostic.

meandave — Tue, 10 Jun 2025 20:19:34 +0000

Mikeal was extremely welcoming to me when I met him over a decade ago, It was either JSConf or NodeCamp, He was always super insightful and encouraging to my personal growth as an engineer and open source contributor. NodeJS wouldn't be what it is without him, especially the community around it in the early days. I got to work with him for a bit at protocol labs. This is a major loss to open source

New comment by meandave in "43K fewer drivers on Manhattan roads after congestion pricing turned on"

meandave — Tue, 14 Jan 2025 04:16:28 +0000

I live at a _very_ loud and busy intersection in downtown manhattan, it's usually gridlocked every day from 4pm - 7pm at least. That hasn't happened once since congestion pricing kicked in (I'm enjoying the relative quiet, but I do sort of miss the chaos). The first two days, everything was covered in snow down here. I wonder how much this will hold up into summertime.

As an unrelated aside a new bmw sedan driving the wrong way on mulberry street intentionally ran into me at a crosswalk today. So don't let your guard down lol

One of the major takeaways from this video is how there is a major conflict of interest when a browser's predominant income is from the search engine. The browser cannot _truly_ be the User's Agent if innovation can mean killing funding.
