My WHOOP has no screen. My Kindle had no job. So I put them together
I run a lot, so every morning I check my recovery and decide whether to run or take a rest day. I wanted an always-on screen that would let me see everything at a glance. Then I remembered the old Kindle collecting dust in the corner. So I built this: WHOOP API → a server on my Mac mini → grayscale PNG → Kindle screensaver. It’s now open source, including the full setup guide.
My WHOOP has no screen. My Kindle had no job. So I put them together launched on August 9, 2026 with 11 votes, #971 of 23,274 launches that month and more than 90% of that year's launches.
In plain words
Kindle for WHOOP transforms an old Kindle e-reader into a low-power health dashboard for WHOOP fitness trackers. The open-source project pulls data from the WHOOP API, processes it on a Mac mini, and displays recovery metrics as a grayscale image on the Kindle's e-ink screen. It's designed for runners and athletes who want to check their daily recovery status at a glance without reaching for their phone, breathing new life into unused devices.

I built a tool to help you read Hacker News on Kindle2022 · ktool.io · ▲393Hi HN, I'm Daniel Nguyen. In June, I quit my job to start indie hacking full-time. The idea of KTool first came to my mind when I was reading "Ask HN: I'm a software engineer going blind, how should I prepare?"[0] I've been wearing glasses since I was 5. My right eye is basically blind. Doctors said there is no chance to cure it. I was genuinely scared. Like holy shit, if my left eye stops working, my life is done. Since then I've been very conscious about time spent on computer screens. That's when I started using Kindle-related products: to offload as many reading materials as possible to…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
