The night my Model 3 died in its sleep: “High Voltage Fuse A Blown” (P0A9501)
Tesla Model 3 dead overnight with “High Voltage Fuse A Blown” (P0A9501) – a false pyro fuse squib resistance alert, reconstructed to the second with Home Assistant, TeslaMate and a cheap BLE listener, plus the collateral damage in my PV system.
The clear-sky line
Three years of Fronius GEN24 data distilled into a clear-sky ideal-produce curve as a Home Assistant template sensor: the envelope-fit math, the validation numbers, and why production sometimes spikes above the ideal line when the sun comes back after clouds.

Wanted my PV history out of Fronius Solar.web, but there’s no bulk export and the official API is paywalled. So a 277-line Python script now does the login and dumps 4 years of production, battery, EV, and Ohmpilot data to CSV – 5 min to yearly. https://github.com/mharizanov/solarweb2csv
The patch that couldn’t install: a WordPress core exploit created an admin on this blog
How a broken auto-updater left my blog open to a WordPress core RCE (wp2shell, CVE-2026-63030) and the boring IP rule that saved it anyway.

41.7 kWh produced and 100% self-consumed today from our 6.4 kWp array today Battery was capped <90% SoC (HA automation, summer heat – keeps the LFP cells happy long-term), so most of that went straight to loads, hot water and the car rather than storage. Overall just about 1MWh production in June, with one more…
Anthropic’s Fable 5 available in Claude
Anthropic’s Fable 5 available in Claude That didn’t last long..  but what were they thinking to begin with? Marketing it for months as “too dangerous to release”, then when the govt believed them, it’s an “oops”..? I believe the ban won’t hold up though.
€14.5k into DIY solar in 2022, or the same into VUAA?
€14.5k into DIY solar in 2022, or the same into VUAA? ETF would be up ~€12.5k on paper, ~€7k after inflation. But the panels generated 27.7 MWh so far – that’s ~€3.5k of grid power I never bought. real gap: ~€4k and shrinking every year electricity gets pricier. no regrets

Our Tesla M3 efficiency vs. outside temperature stats for the last 10K km driven, collected using TeslaMate. No surprises here, driving at 20 °C outside is most efficient

Reflective stickers on my DJI Mini 5 Pro to help keep birds away. Registration and phone number printed in bright yellow – easy to spot, and the bright color maybe helps with birds too.

Built a tool to help my daughter prep for her 10th-grade national exams and 12th-grade matriculation exams -and, without her knowing, set a little trap to catch AI use. Well, it sprang sooner than expected 😂

Got an electric @STIHL trimmer – tired of the fiddly, needy gas one. Loving it. Might go electric for the mower and chainsaw too. One only needs to remember to change the battery upfront..🪫

Decoding the local Viber DB to extract messages
How an AI agent decrypted the local Viber database on my Mac in seven hours – a research experiment showing the technical barrier to hacking has collapsed.

Free image diff tool that compares two screenshots or diagrams in the browser – auto-alignment, five comparison modes, no uploads to anyone’s server.
AI capabilities double every 7 months
At BASSCOM AI conference in Sofia, Anthropic’s Patrick Dreisch delivers interesting insights now He says AI capabilities double every 7 months now This stroke me deep – “people are the bottleneck” by EnduroSat’s Krasi Stoev. Sad but true
2D orthophoto/3D point cloud viewer
Vibe-coded a 2D orthophoto/3D point cloud viewer so I can share my drone-captured collections with friends. It supports WebODM exported assets.

EV electricity since late Feb
Have not paid for EV electricity since late Feb, going purely on solar. More than 800km driven so far, feels illegal.

Speed camera watchdog for the Tesla
Added a speed camera watchdog for the Tesla using live Waze report-scraped data. Implemented same-street filtering to drop false positives from nearby roads. Still far from ideal. Don't ask why I needed this.
AI model benchmarking at contextarena.ai
Interesting AI model benchmarking at https://contextarena.ai/. I like how it visualizes the loss of attention as context increases – something many don't realize

OpenClaw on a cloud VPS
Just finished setting up OpenClaw on a cloud VPS. I'll be chatting with it over a private Discord server/channel. I've set it to use anthropic/claude-opus-4-6, so it should be quite powerful. Fun times ahead. OpenClaw is burning through tokens like crazy. Had to revert to more basic models after shelling out $35 in three hours.…
Home energy tracking
Progress on home energy tracking, but many more devices still need to be added. Shelly EM-50 will help cover more of the untracked consumption

5000 km driven with our new Tesla
Slightly over 5000 km driven with our new Tesla in the three months since we got it. The app estimates 625 BGN (320 EUR) in savings compared to an ICE vehicle. Actual savings are even higher, as 16% of the charged power is free PV produced at home.
Heat pump defrosting today
Our heat pump spent 103 minutes defrosting today, with two more hours to go. Not ideal, but such days are rare. It's foggy outside, with temperatures around freezing.
