Forecast: nerd fight with cute graphics
Weathergotchi – an open-source climate Tamagotchi
Cute weather pet or fake Tamagotchi? Commenters are absolutely split
TLDR: Weathergotchi is an open-source mini device that tracks room conditions and shows them on a low-power screen for over a week on battery. But commenters fixated on whether it deserves the “Tamagotchi” name, turning a calm maker project into a surprisingly funny branding debate.
A tiny open-source gadget that tracks temperature, humidity, battery life, and weather history on a paper-like screen should have been a straightforward maker win. Instead, the internet instantly turned it into a naming war. The device itself is real-deal DIY candy: a small battery-powered logger with a custom case, a little display that stays visible all the time, and files released so people can build or modify it themselves. For hardware hobbyists, that’s catnip. But for the comments? The real storm was over one word: “gotchi.”
Several readers were deeply unconvinced by the Tamagotchi comparison, basically accusing the project of cute-name inflation. One commenter flatly said calling it a Tamagotchi is “silly,” arguing that the label sets up the wrong expectations and sells short what is otherwise a neat weather tracker. Others piled on with variations of the same roast: if it’s a “-gotchi,” where’s the pet drama, the feeding, the chaos? One person joked, “Do you have to keep the device alive by... seeing new types of weather?” Another delivered the bluntest review possible: “This doesn’t look as fun as a Tamagotchi.” Ouch.
Still, not everyone came to fight. One commenter was genuinely excited about the open design and wondered if there’s a ready-made fully open hardware option for people who want the software fun without rebuilding the same gadget from scratch. And the YouTube video got a surprise side quest of praise for being funny and self-aware. So yes, the gadget may log climate data—but the comments logged mild identity theft, nerd nitpicking, and some very solid jokes.
Key Points
- •Weathergotchi is an open-source, battery-powered temperature and humidity logger with an always-on 1.54-inch e-paper display and onboard historical graphing.
- •The project publishes complete source materials, including hardware schematics, PCB layout, firmware, and 3D-printable enclosure CAD files.
- •Its firmware targets an ESP32-S3 using PlatformIO and the Arduino framework, handling sensing, timekeeping, EEPROM logging, display updates, and power management.
- •The hardware uses shared I2C peripherals including SHT45, DS3231, 24LC512, and BQ27441, while the e-paper display is connected over SPI and power control uses LTC2954 with BQ24075.
- •The low-power design is described as enabling more than one week of operation on a small Li-Po battery, though the author notes battery state-of-charge reporting accuracy issues during testing.
