Tom Nardi’s October 6, 2026 Hackaday article reports a 240×240-pixel example made with Python and Pillow, and says GIFs are supported too. The exact SmallTV model in the demonstration is not identified, so check compatibility for your device variant rather than assuming every model behaves identically.
What the low-fuss SmallTV hack does
The GeekMagic SmallTV line consists of compact display gadgets built around ESP8266 or ESP32 microcontrollers. In the Hackaday demonstration, a networked computer creates an image and pushes it to the SmallTV over HTTP; the device’s built-in photo viewer then displays it. The stock software stays in place, and the reported method does not require soldering.

Hackaday describes the workflow this way: “All you need to do is create a 240×240 image and shoot it over to the device, so you’re free to come up with whatever sort of visuals you’d like.” The 240×240 figure is the image size in the example, not a performance measurement or a universal compatibility guarantee.
What you can display
The example uses Python and Pillow to generate a 240×240 image showing Claude and Codex usage data. Those tools are examples, not stated requirements: the image can be created with another language or tool, as long as it is suitable for the device’s photo viewer and the workflow can send it to the SmallTV. Hackaday also reports GIF support, allowing animated content.

This approach changes the visual content shown by the existing software; it is not an installation of a new operating system or firmware. The article does not provide a controlled performance comparison or identify the exact model used in the demonstration.

Sending an image through the built-in viewer and replacing firmware are separate projects. The first keeps the stock software and centers on image creation and an HTTP transfer. Firmware replacement changes the device software and depends more heavily on the hardware variant and its installation method.
Quick Recap
| Consideration | Built-in photo viewer | Alternative firmware |
|---|---|---|
| Stock software | Retained; the image is displayed through the existing viewer. (Hackaday, October 6, 2026) | Replaced or modified, depending on the project and procedure. (smalltv-ultra documentation: project repository; SmallTV project repository) |
| Technical work | Create an image and send it to the device over HTTP. Python and Pillow were used in the report, but are not presented as mandatory. (Hackaday, October 6, 2026) | Flash firmware using the method specified for the exact board variant; project documentation describes different procedures. (smalltv-ultra documentation: project repository; SmallTV project repository) |
| Hardware access | The reported method avoids soldering. (Hackaday, October 6, 2026) | Some documented methods use OTA updates; other boards require USB or UART access. Soldering requirements are not established for every variant. (smalltv-ultra documentation: project repository; SmallTV project repository) |
| Variant compatibility | The demonstration’s exact model is not named, so compatibility across the product line is not established. (Hackaday, October 6, 2026) | Installation procedures differ by hardware variant; follow the instructions for the board you have. (smalltv-ultra documentation: project repository; SmallTV project repository) |
| Security and recovery | The report does not specify security or recovery behavior for the stock image-transfer workflow. | The smalltv-ultra repository warns about shared default credentials, plain HTTP, possible bricking, and advises against exposing the device to the internet. These cautions apply to that project’s documented firmware, not automatically to stock software or every alternative firmware. (smalltv-ultra documentation: project repository) |
How to choose a route
- Choose the photo-viewer method if your goal is to show custom artwork, information, or other visuals while leaving the device’s software intact.
- Consider firmware replacement only if you want capabilities that the stock viewer does not provide and are prepared to follow variant-specific flashing instructions and account for recovery and security risks.
- Verify the model first if you are buying a SmallTV specifically for this workflow. The demonstration covers the product line but does not name the unit used or establish compatibility for every variant.
