The Cutest Weather Forecast on E-Ink and ESP32

17 January 2026 at 19:00
A photo of the cats and the generated image

There’s a famous book that starts: “It is a truth universally acknowledged that a man in possession of a good e-ink display, must be in want of a weather station.” — or something like that, anyway. We’re not English majors. We are, however, major fans of this feline-based e-ink weather display by [Jesse Ward-Bond]. It’s got everything: e-ink, cats, and AI.

The generated image needs a little massaging to look nice on the Spectra6 e-ink display.

AI? Well, it might seem a bit gratuitous for a simple weather display, but [Jesse] wanted something a little more personalized and dynamic than just icons. With that in the design brief, he turned to Google’s Nano Banana API, feeding it the forecast and a description of his cats to automatically generate a cute scene to match the day’s weather.

That turned out to not be enough variety for the old monkey brain, so the superiority of silicon — specifically Gemini–was called upon to write unique daily prompts for Nano Banana using a random style from a list presumably generated by TinyLlama running on a C64. Okay, no, [Jesse] wrote the prompt for Gemini himself. It can’t be LLM’s all the way down, after all. Gemini is also picking the foreground, background, and activity the cats will be doing for maximum neophilia.

Aside from the parts that are obviously on Google servers, this is all integrated in [Jesse]’s Home Assistant server. That server stores the generated image until the ESP32 fetches it. He’s using a reTerminal board from SeedStudio that includes an ESP32-S3 and a Spectra6 colour e-ink display. That display leaves something to be desired in coloration, so on top of dithering the image to match the palette of the display, he’s also got a bit of color-correction in place to make it really pop.

If you’re interested in replicating this feline forecast, [Jesse] has shared the code on GitHub, but it comes with a warning: cuteness isn’t free. That is to say, the tokens for the API calls to generate these images aren’t free; [Jesse] estimates that when the sign-up bonus is used up, it should cost about fourteen cents a pop at current rates. Worth it? That’s a personal choice. Some might prefer saving their pennies and checking the forecast on something more physical, while others might prefer the retro touch only a CRT can provide.

Poha Rasayana

Flattened rice, commonly known as poha, is rice which is flattened into flat, light, dry flakes originating from the Indian subcontinent. These flakes of rice swell when added to liquid, whether hot or cold. The thickness of the flakes varies between almost translucently thin to thick Poha and used in varieties of Indian dishes. It is called by different names in different regions, such as Avalakki (ಅವಲಕ್ಕಿ) in Kannada, Atukulu in Telugu,  Aval in Tamil & Malayalam, Poha in Hindi.

Avalakki Rasayana/Sihi Avalakki/Sweet Poha is a famous dish from Karnataka, usually prepared during festivals to offer as a Prashad to Lord during Tulasi festival or Krishna Janmashtami. Poha/Aval is Lord Krishna’s favorite food, so avalakki kayi bella is prepared for his offerings. Avalakki Rasayana is a very simple dish, involves no cooking, so could be a great energy dish for ones who are fasting for festivals


Red Poha vs White Poha! How to use RED POHA?

“Red Poha”

Most Indians kickstart their day with Poha for breakfast. So why not try your breakfast with healthy Poha. A healthier variation to the everyday poha is the red poha, which is made from red rice. Moreover, unlike white rice, red rice doesn’t undergo excessive processing, and as such the other bran layer remains intact. Red poha is slightly coarser in texture as compared to white poha.  Red poha can be used pretty much the same way as white poha. You need to rinse the poha 2-3 times and soak it in water first, for at least 10 minutes, so that it softens and then use in many dishes such as salads or stir fry with other vegetables and spices or use in cutlets. This rasayana recipe calls for Red Poha, but you could still use white Poha. It is really about making a healthier choice.

I Usually prepare rasayana as a side dish whenever I make avalakki oggarane (which is the spicy version of poha) for breakfast. Great to pack it in a lunch box too. This Rasayana is a mixture of Red Poha, Jaggery, Coconut, Banana, and Cardamom powder. I call this recipe as 5-ingredient Rasayana that could be prepared within 5-mins.

We had a lot of jackfruits this summer and was finding ways to use in recipes. So thought why not dump into sweet Poha dish and trust me, it tasted so good and made an awesome combination with banana and Poha. Make sure to use only ripe Banana and Jackfruit for this recipe. Jackfruit is purely optional, skip if unavailable. Make this simple no-cook yummy rasayana for breakfast or pack it for lunch box.

Notes

Many variations can be made to this dish,
  • Red Poha can be replaced with white Poha too.
  • Add more or less of jaggery as per taste. You could also replace with sugar or add half Jaggery and half sugar. You could also add a spoonful of honey.
  • Jackfruit is optional. Add only if available for the season. Traditional Rasayana is done just with banana.
  • Roast few finely chopped cashews and almonds in ghee, along with dry grapes and add to Rasayana.
  • No need Soaking if using thin flakes of Poha. The juice from the sugar/Jaggery and banana is sufficient enough to make it soft.
