Claude fixed an e-ink screen's firmware for full 6-colour display
Their reTerminal E1002 e-ink display needed a dashboard and firmware that accepted all 6 colours. Claude did both, after earlier reverse-engineering their NAS's LEDs. They vibe-debug 10x more than they vibe-code.

“most recently, a TRML dashboard for my Seeed Studio reTerminal E1002 smart e-ink display, and I also had to have Claude fix the firmware for full 6-color input”
Verified: these results were checked against evidence by Agents in the Wild.
What they did
Built a dashboard for their Seeed Studio reTerminal E1002 smart e-ink display, and had Claude fix the firmware to accept full 6-colour input. Earlier, Claude reverse-engineered the LEDs on their Lincstation N2 NAS so a daemon could set them properly, and helped build Thufir, a task manager to replace Things.
How it went
The display and NAS projects work. The task manager is still janky but usable enough for their purposes. They say they vibe-debug 10x more than they vibe-code.
Try it yourself with Claude
I have a [device] e-ink display. Build a dashboard for it showing [weather, calendar, tasks], laid out for its resolution and colour palette. If the firmware can't display all the colours the panel supports, find out why from the source and propose a fix, and explain the risk before I flash anything.

After $45 in GitHub Actions overage in one month, a solo founder put an idle homelab to work as CI runners, with Claude making it easy to set up. Daily spend dropped from $2-4 a day to under $0.25.
A first homemade synth has 36 hall-effect keys and buttons and 7 rotary encoders. The firmware started by hand, then gentle prodding at Claude got everything needed much faster. Rev 2 of the PCB is nearly done.
Working on a Quake project, Claude decided on its own to build a test suite: demo playbacks with snapshots compared pixel by pixel, plus recorded demos whose screenshots it checked for each element.
After building a minimal proof assistant, the writer asked Claude how they knew the prover was actually sound. Claude checked, found five different ways it could prove false theorems, and fixed them.
Four years after shelving a homemade RSS reader and selling off its $500 domain, the writer built it this year with Codex and Claude. They use it daily, along with 30 other strangers who found it public.
Chasing a childhood itch for the exact 1996 After Dark Flying Toasters screensaver, the writer turned to Claude. It did a lot of good reverse-engineering work, but kept inventing details that needed pushback.
