With this in mind I've created this Google Form for people to submit details of what they've found in their local stores.

Add your submissions here:

There's a link from the form to view previous submissions, for you to use however you wish.

Please boost!

LightInk – An ESP32-based, solar-powered E-ink smartwatch with up to 10 months of battery life

LightInk – An ESP32-based, solar-powered E-ink smartwatch with up to 10 months of battery life

Daniel Ansorregui has developed LightInk, an open-source solar-powered E-ink watch inspired by 90s solar digital watches. It features a 1.54-inch e-paper display and supports Wi-Fi, Bluetooth, LoRa, and GPS, running on a 100mAh battery. The project integrates a custom low-quiescent-power design using a TPS63900 buck-boost converter, capacitive-touch input, and deep-sleep-driven firmware, along with ultra-fast partial e-ink updates (<1 ms active time) and precise RTC timekeeping with drift calibration. It also supports solar-first operation (no dedicated charging IC) and dynamic power gating of peripherals, enabling around 9–10 months of operation on a small battery supplemented by solar power. LightInk specifications: System-in-package - ESP32-PICO-D4 SiP CPU - Dual-core processor @ 240MHz Memory - 520KB SRAM Storage - 4MB flash Wireless - 2.4 GHz Wi-Fi 4 up to 150 Mbps and Bluetooth 4.2 BR/LE connectivity Display – 1.54-inch 200×200 B/W e-Paper panel (GDEH0154D67 or compatible) Audio - 10-15mm piezo electric disc speaker Connectivity

#dnesbastlim Upravil jsem fw @zivyobraz pro #epaper Good Display GDEP073E01. Pinout ESP32 Dev Kit se od Demo Kit liší, tak bylo nutné definovat nový board. Navíc má ESP hodně mizernou Wi-Fi anténu, tak jsem musel pomocí flagu "zpátky na stromy" a připojit se k serveru přes http 🙈😁
