Muse Charm: Building an AI Tamagotchi Before Meta's Launch
In a creative experiment, Sean Hollister constructed his own AI Tamagotchi-like device, the Muse Charm, before the official launch by Meta, showcasing its capabilities and user experience improvements.

A Unique Take on AI Gadgets
Mark Zuckerberg’s Meta introduced the Muse Charm, a cute AI-driven gadget designed to act as a personal assistant reminiscent of a Tamagotchi. However, tech enthusiasts like Sean Hollister have chosen to build their own alternatives, like the Muse Charm, instead of purchasing Meta’s version. For just $50, he created an AI gadget that surpasses the basic functionalities offered by Meta's Charm, proving that a DIY approach can be both cost-effective and rewarding.
What Is Muse Charm?
The Muse Charm is built around the Waveshare ESP32-S3 1.75C, a compact 1.75-inch touchscreen smart device. While Meta's official Charm features advanced tech like cameras and 5G connectivity, Hollister's version lacks these luxuries but still provides a delightful user experience. His gadget serves multiple purposes, functioning as a pocket watch and a remote camera viewfinder, with added functionality for controlling smart home devices, given the right tweaks.
Initial Challenges with Setup and Functionality
Upon receiving the Waveshare device, Hollister faced a myriad of issues out of the box. The initial setup included plugging the device into a PC, linking it to the Muse phone app, and utilizing Meta’s open-source code found on GitHub. Unfortunately, Muse misinterpreted audio commands as transcriptions at first, leading to confusion. The responses from the AI helper were also slow and restricted to a few words on the tiny screen, making interaction cumbersome without a separate device for context.
Enhancing Functionality Through Customization
Despite the initial challenges, Hollister was determined to enhance the capabilities of his DIY Muse Charm. Utilizing Claude Code, he was able to reprogram the pendant to address its shortcomings. Key improvements included:
- The addition of a conversation history page for better readability.
- Integrating a more expressive British AI voice from ElevenLabs for spoken responses.
- Implementing a remote shutter functionality, allowing the device to take pictures from afar with a high-quality preview.
All adjustments came as a result of straightforward coding instructions from Claude, showcasing how accessible gadget programming can be, even for those with no prior coding experience.
Creating Engaging Interactive Features
One of the standout features of Hollister's Muse Charm is the integration of fun, interactive avatars designed to keep users engaged. Hollister programmed Tamagotchi-like minigames where the avatars require feeding, playing, sleeping, and bathing. The complexity was increased by designing several levels of hunger, boredom, and dirt—levelling up the avatar experience in a playful way that extends beyond the basic offerings by Meta. This customization process also allowed the avatars to become dirtier when fed crunchy treats, enhancing the playfulness and engagement of the device.

Concerns About AI and User Security
In light of using Meta’s AI technology, Hollister expressed concern about the safety and privacy implications of integrating such a device into his life. Following reports about privacy breaches, including the leaking of personal data like home addresses, he took precautions by connecting his device to a guest Wi-Fi network to safeguard sensitive information while still enabling the gadget’s functionalities.
Comparison with Meta's Market Offerings
While the Muse Charm from Meta aims to entice consumers with its adorable designs and integrated features, Hollister's DIY version illustrates both the potential and limitations of commercial AI gadgets. Meta's variant comes with advanced capabilities, but many enthusiasts may find more value in the ${50} DIY route, given that they can customize every aspect to fit their personal needs. Moreover, Meta’s current offerings may not allow the same level of programming freedom as seen with Hollister’s version, raising questions about whether the typical user will find Muse’s features extensively useful or if they would benefit more from open-ended devices like Hollister’s build.
Looking Ahead: The Future of AI Gadgets
The Muse Charm is slated for release this holiday season, and it will be interesting to see how it performs against both user expectations and its higher-priced competitors. For Hollister, the experience of developing his gadget from scratch has opened possibilities for future enhancements or entirely new projects. Whether the official Muse Charm offers the same level of customizability or user usability remains to be seen, but the marketplace is set for an intriguing evolution in AI-powered personal devices.
Key Takeaways
- Hollister built his own version of the Muse Charm for $50 using the Waveshare ESP32-S3 1.75C.
- The DIY gadget serves multiple roles, including a pocket watch and remote camera viewfinder.
- Customization with Claude Code significantly enhanced user experience and functionality.
- Concerns regarding user security led to prioritizing privacy by using a guest Wi-Fi network.
- Meta's Muse Charm is set to launch this holiday season, but user customization remains a key question for its appeal.
