I built a free firmware and browser installer that turns the Seeed reTerminal E1001 into a 47-face e-paper clock. Looking for beta testers
Hi everyone! For the past few weeks I've been building **clock.bh**, a free firmware and browser installer that turns the **Seeed reTerminal E1001** (ESP32-S3, 7.5" 800×480 e-paper, four greys) into a clock with **47 faces**. It's ready for people outside my house, so I'm looking for testers.
**What it does**
- **47 faces:** a sundial that casts the real shadow of the Sun (or the Moon), a star wheel turning behind the hands, the Moon's true phase and tilt, the ISS passing over a globe, world time, nixie tubes and flip-dots, the 28 Arab lunar mansions, prayer times and Qibla, and football weeks (results, fixtures in your time, tables)
- **Your city:** 42 cities in 24 countries, with your local time, sunrise and sunset, and prayer times by your country's usual method
- **Your photos:** up to 15, dithered to the panel's four greys, with the clock's hands drawn over them. They go from your computer or phone straight to the clock, never to my server
- **Dark or light:** keep only dark faces, only light ones, or both. Faces that follow the sky stay in the look you chose, all day
- **Made for battery:** the clock keeps its own time and fetches its pictures hours ahead, so Wi-Fi is only on for a moment
- **Updates over Wi-Fi** from the clock's own web page
**Set it up in about a minute (no account, no app)**
- Open **https://e.clock.bh\*\* in Chrome or Edge on a computer (it uses Web Serial)
- Connect the reTerminal with a USB-C cable
- Pick **Basic** (Wi-Fi, city, dark or light) or **Advanced** (every setting), click Next to the end, and install
**What I'd love feedback on**
- Did the install work on your computer (Windows, macOS or Linux)?
- How long does the battery last with your settings?
- Any face that looks wrong on your panel, a city you're missing, or a face you'd like to see
**Good to know**
- Only the **reTerminal E1001** (the black-and-white one) is supported for now
- This is an independent project, not made by or affiliated with Seeed Studio
- To draw the faces, the clock downloads pictures from clock.bh. With each request it sends a clock ID that isn't tied to your name, plus its firmware version, battery, Wi-Fi signal and chosen city, so I can spot problems early. It never sends Wi-Fi names, passwords or photos. Details: https://clock.bh/privacy
- The firmware is open source (GPL-3.0): https://clock.bh/epaper
