HomeCostRadar

What it does

HomeCostRadar helps homeowners estimate the real cost of running and maintaining a home. Calculate appliance energy costs, estimate electricity usage, build a personalized maintenance plan, and forecast how much to set aside for future repairs. Every estimate shows its assumptions, data source, methodology, and confidence level—so you can understand where the number came from instead of trusting a black-box result.

Estimate home energy, maintenance, and replacement costs with transparent sources, methodology, ranges, and confidence for every number.

HomeCost Radar estimates your home’s operating and repair costs and shows a range, your confidence level, and exactly which data source and methodology produced every number. No fake precision, no hidden assumptions. Estimate appliance running costs and your monthly bill, browse 46 appliance cost guides , or compare electricity rates across all 50 states . A climate-aware task list that explains why each task matters, what triggered it, and where the guidance comes from. Every estimate links to its data vintage and versioned methodology. We never present a state average as your exact tariff. Appliance operating cost, an electricity bill estimator, a personalized maintenance planner, and a…from homecostradar.com

  Hi HN — my wife and I built HouseTrak out of frustration. Every time something broke or needed maintenance, the info was scattered: notes app, photos, emails, spreadsheets, reminders. There wasn’t one place to keep everything about our home. So we built HouseTrak — a simple iOS app that keeps maintenance, projects, assets, and important home details in one place. One app for everything about your home. It’s intentionally minimal and focused on being useful, not clever. Would love feedback, especially from homeowners: How do you currently track home maintenance? What’s missing from tools…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
